submarine

The ultra-luxury cruise ship recently docked in London for the first time so I went to see what passengers can expect from a holiday that includes two helicopters and a submarine

As a travel journalist, I often have to convince people that my life isn’t all glitz and glamour, but it was difficult to argue my case as I sat drinking champagne on a six-star cruise ship.

The Scenic Eclipse II docked for the first time in London last month, and I got the chance to have a nosey around and see what life is like onboard this luxury vessel. Coming out of the very unglamorous tube, I immediately spotted the boat moored just off of Greenwich Pier, looking more like the kind of superyacht you’d see in the waters of Monaco than in the murky Thames.

While many cruise lines compete to build bigger and bigger ships, Scenic Eclipse II has focused on quiet luxury and an exclusive experience for those onboard. Only 228 guests can board each of its voyages, (200 if it’s visiting polar waters) and with a staff ratio of nearly 1:1, service is incredibly personal. Each of its 114 suites comes with butler service, and the layout means everyone gets a veranda where they can enjoy the views. Which is handy, because the ship visits plenty of places where you’ll need a good camera.

Our group took a quick, if choppy, Thames Clipper service across to the Scenic, and were relieved to step onto its much more stable floors. As soon as you step onboard, you definitely feel the luxury vibes, and it felt more like the lobby of a five-star hotel than a cruise ship. Sipping a glass of champagne in the plush lounge, and taking a sneaky peek at the top shelf drink selection for all-inclusive guests, I started to make a plot to stowaway on the ship.

But I settled for a sneaky peek around its deluxe rooms instead. Firstly, to one of the top decks to see the vast Owner’s Penthouse Suites, set at the front of the ship so you get to make the most of the views, presumably while soaking in your private spa tub while the butler tops up your drink. It had a plush bedroom area, huge living room with its own bar, and walk in-closets where you can store all your best cruising outfits for black tie galas.

You certainly won’t be slumming it if you opt for one of the lead-in Verandah Suites. These have a king-size bed, a curtained off living area, and marble en-suite bathrooms, and even the ‘basic’ level rooms on this ship get butler service, in-room dining, and much more included.

Of course, nobody goes on a cruise just to sit in their room, and Scenic Eclipse II is clearly for cruisers who have a more adventurous side. Passengers can book trips on one of the ship’s two helicopters, or even get onboard its submersible to explore the deepest waters with 360-degree views. The relatively small size of the ship compared to many mega cruise ships mean it can also visit a wider variety of places, and its itineraries range from Antarctic adventures to relatively tame Mediterranean voyages.

One feature that I found really fun was that the navigation deck would be kept open for the duration of the cruise, so you can pop along and chat to crew members, see the equipment up close, and live out your fantasies of being captain. But sadly, they won’t let you press the buttons.

A team of 38 chefs onboard means you have a huge range of culinary options for a relatively small ship, about 10 all-inclusive choices overall from lounges with snacks and coffee to impressive Italian, fine French dining, a sushi counter, and a Teppanyaki grill experience.

Add to this a couple of pools, an incredible spa with a gym and yoga room, and a plush lecture theatre offering a program of talks as well as workshops and entertainment, and I can’t imagine you’d ever get bored during your cruise.

After leaving Greenwich, the Scenic Eclipse II is made its way to Hamburg, continuing through Ostend, Belgium, before cruising the Elbe River. This five-night itinerary starts at £4,4951 per person.

The specifications of the ship mean it has plans to visit some of the world’s most extreme environments in the future, including Antarctica and the Arctic, as well as classic Mediterranean destinations, Oceania, and the remote archipelagos of South East Asia and Indonesia.

The U.S. Navy has shared details about its vision for a new family of modular surface-to-air missiles that is expected to include a version that will arm future variants of the Virginia class submarine. This would be an all-new capability for the service, at least as far as we know. All of the members of the Naval Modular Missile (NMM) are set to be based around a common Terminal Stage Interceptor (TSI), creating a range of capabilities in very different form factors. This, in turn, opens a door to new options for larger and/or mixed loadouts in vertical launch systems on surface warships and submarines.

New information about the Navy’s NMM concept is contained in a draft request for solutions contracting notice recently posted online, which Aviation Week was first to report on. Naval Sea Systems Command (NAVSEA) hosted an NMM Industry Day event earlier this year to get feedback from prospective vendors. The NMM effort traces its roots back to at least 2021, but the Navy has only released limited details about its plans for these new missiles in the past.

“The United States Navy (USN) is seeking a new, modular interceptor to serve as the basis for the Naval Modular Missile (NMM) program, a next-generation initiative designed to revolutionize surface naval capabilities through multi-mission utility, enhanced capacity, and a modular open architecture,” according to the recent draft request for solutions notice. “The NMM TSI is a modular, highly capable multi-mission interceptor that leverages state-of-the-art technology to provide effectiveness across the entire mission space.”

“The TSI is ten inches in diameter and consists of five modules,” which are “the Seeker Assembly Module (SAM), Lethality Module (LM), Command Module (CM), Terminal-Stage Rocket Motor (TSRM), and Control Actuation Module (CAM),” the notice adds. “This TSI will be integrated with multiple booster stacks and canisters to achieve a robust family of multi-mission and multi-platform variants.”

To start with, the contracting document describes the desired TSI as “highly agile” and “multi-mission capable,” but does not lay out any hard performance or capability requirements.

When it comes to the TSI’s seeker, there are certainly multiple options for prosecuting an aerial intercept, including active radars, imaging infrared sensors, and passive radiofrequency (RF) capabilities. Though we do not know yet what the Navy’s requirements here might be, a multi-mode seeker system could also be extremely valuable as the countermeasure ecosystem continues to expand.

An interceptor with a high degree of agility would also be required for any NMM variants intended to address high-supersonic and/or hypersonic targets, especially ones with their own ability to maneuver significantly during mid-course and/or terminal phases of flight. The Navy has made clear in the past that addressing the threats posed by ever more advanced supersonic and hypersonic anti-ship missiles, including air-breathing types, as well as ballistic and hypersonic designs, is a top priority. This has only been underscored by lessons learned from recent conflicts in and around the Middle East, as well as observations from the war in Ukraine. Those threats are only expected to be magnified in any future high-end fight against an adversary like China or Russia. Both of those countries have been investing heavily in the development and fielding of new high-speed anti-ship missile capabilities.

All this being said, the TSI element is perhaps the least interesting part of the overall NMM concept the Navy has now outlined. The service envisions at least four distinct NMM “All-Up-Rounds,” or AURs, topped with the common interceptor. As described now, the missiles are very different in form and function.

There is a Long-Range (LR) version that “brings multi-mission, hypersonic capability to the Mk 41 Vertical Launching System (VLS),
leveraging existing USN investments in a 21” rocket motor and fully integrating with future Long-Range Fires kill chains,” according to the recent notice. A single LR NMM will be able to fit inside a Mk 41 Vertical Launch System (VLS) cell.

A 21-inch rocket motor is a key component of the Standard Missile-3 Block IIA anti-ballistic missile interceptors in Navy inventory today. A similarly sized rocket motor is also a central feature of the still-in-development supersized Block IB version of the Standard Missile-6 (SM-6). Existing variants of the SM-6 are multi-purpose missiles that can be employed as anti-interceptors, including against certain hypersonic threats, as well as surface targets. The rendering the Navy has shown now of the LR version of the NMM is very much in line with the overall designs of the SM-3 Block IIA and SM-6 Block IB.

In addition, the Navy wants slimmer extended and medium-range NMMs that can be dual- and quad-packed into a single Mk 41 VLS cell, respectively. These are called the DP-ER and QP-MR versions. It’s worth noting here that the service uses similar extended and medium-range terminology today to describe different variants of the Standard Missile-2 (SM-2). Those missiles are primarily employed as surface-to-air interceptors, but have a limited secondary surface-to-surface capability, as well. However, SM-2s can only be loaded singly in Mk 41 VLS cells. The Navy is now in the process of integrating the Patriot PAC-3 Missile Segment Enhancement (MSE) interceptor into the Mk 41, offering another alternative to SM-2, but those missiles will also be loaded one per cell, at least initially.

The last and most notable version of the NMM that the Navy has outlined now is an extended-range version intended to be launched from future subvariants of the Virginia class nuclear-powered attack submarine equipped with the Virginia Payload Module (VPM). The VPM consists of four large vertical launch tubes and is set to be integrated first on Block V Virginia class boats. The so-called ER-S member of the NMM family would be loaded into those tubes via a seven-cell Multiple All-Up-Round Canister (MAC) adapter, first used on Ohio class guided missile systems.

The Navy does not currently have an operational submarine-launched surface-to-air capability at all, at least that we know about. This is something that has been explored by navies globally to varying degrees for decades, as you can read about more in this past TWZ feature. We will come back to this later on.

The NMM concept presents clear potential benefits operationally. The Navy’s 2027 Fiscal Year budget request indicates the service is aiming to eventually supplant all of its existing Standard missiles with NMM types. The new modular missile family could conceivably replace other munitions. With a new common TSI interceptor, even shorter-range NMM versions could offer expanded capability against an array of aerial threats in different envelopes. The Navy’s description of the LR type, at least, as a multi-mission weapon, also points to new capability against surface targets.

It’s also important to point out that the Navy says the LR and ER-S versions will be capable themselves of traveling at hypersonic speeds, helping to close any kill chain faster, even at extended ranges. This would be especially important for engaging incoming hypersonic threats, something the Navy can only currently do with versions of SM-6, to at least some degree. Depending on the full scope of capabilities the Navy has planned for NMM, this could open the door to new options for strikes on time-sensitive or otherwise fleeting surface targets.

The DP-ER and QP-MR versions would bring valuable additional magazine depth. Currently, the lower-end Evolved Sea Sparrow Missile (ESSM) is the only surface-to-air interceptor in Navy inventory that can be multi-packed into VLS cells on its surface ships. Greater magazine depth means more engagement opportunities before having to reload, a process that currently requires Navy warships to leave their stations and head to a friendly port. During those transits, they may also be more vulnerable due to limited remaining ordnance. Especially in the face of growing threats to established port facilities, the Navy is also pursuing new at-sea reloading capabilities to create additional operational flexibility and reduce vulnerability. These issues have also been highlighted by recent U.S. operations in and around the Middle East.

The NMM plan would present benefits logistically and when it comes to production, too. Multiple contractors could be brought on to produce TSIs and the different rocket motors, creating opportunities for competition and cost savings, as a result. It could also help with ramping up production at scale. The recent NMM contracting notice says the Navy could leverage multiple vendors just to produce the modular components of the TSIs, and that the service is aiming for a production rate of 1,000 interceptors per year within five years of a contract award.

These are all considerations that are top of mind for the U.S. military at present when it comes to anti-air interceptors, as well as other munitions. Higher-end surface-to-air missiles have historically been very long-lead-time items with the delivery timelines measured in months, if not years. This has already created serious issues for sustaining stockpiles that have been exacerbated by a succession of crises in the Middle East, as well as the need to support allies and partners, especially Ukraine.

Overall, NMM “will provide the US Navy, Joint Force, Allies and Partners with advanced defensive and offensive capability to out-pace the threat. As the effective range, capability and capacity of adversary anti-access/area denial (A2/AD) systems have increased, the US Navy and Joint and Allied forces are at increased risk,” the Navy’s budget documents explain. “Additionally, adversary capacity and expected large raid engagement tactics will demand US and Allied forces increase their platforms’ defensive capacity (depth of magazine) or be forced to resupply frequently in the midst of combat operations. The adversary’s increased capacity comes with increased capability in the form of highly-maneuverable, complex threats that will stress the current U.S. weapon systems capabilities.”

Then there is the additional matter of the submarine-launched capability. As stressed from the start, the explicit inclusion of the ER-S version in the NMM plan is especially significant since this is not something the Navy is known to have access to at all right now. TWZ has previously explored in detail the potential benefits, as well as drawbacks, of arming submarines with anti-air interceptors.

Historically, the most immediate use case for a submarine-launched anti-air missile capability has been localized defense against anti-submarine aircraft and helicopters, as seen in the video below. The threat of a submarine shooting back could have a deterrent effect, too. Still, a submarine could have to get close to the surface and otherwise expose its position to prosecute such an engagement. A submarine launching anti-air interceptors is not automatically guaranteed to achieve a kill, either. This all raises a question of the value proposition compared to simply trying to evade detection and escape pursuers. There are rules of engagement and other questions to be answered, as well, as you can read more about here.

However, the extended-range nature of the ER-S NMM variant raises the possibility of a different concept of operations involving a deep integrated and fully networked kill web, which is an area the Navy has already been investing in heavily. In this context, submarines might offer broader additional anti-air engagement capacity as part of a larger defensive posture around carrier strike groups, other surface action groups, and even potentially friendly assets on island outposts or along other coastlines, although this is unlikely to be the primary use of this capability set.

Submarines offer inherent survivability benefits and can operate discreetly across broad areas for extended periods of time. This, in turn, could create additional challenges for opponents who would have to account for the potential of additional surface-to-air capabilities to be hiding underneath the waves. Similarly, ER-S-armed submarines could be used proactively to take out enemy aircraft in areas far forward of any other friendly forces, and without opponents knowing they are there to begin with. This could be an especially valuable tool for targeting airborne early warning and control planes and other prized strategic force multiplying platforms. Targeting data could come from many sources, including future air moving target indicator space sensing layers, but also from warships equipped with the Aegis combat system or aircraft, including future sixth-generation F/A-XX fighters operating beyond the reach of their weapons capabilities. Acting as forward remote ‘shooter’ nodes, submarines would be very unpredictable and dangerous counter-air assets. Ukraine, for instance, has leveraged remote forward ‘shooter’ concepts in a similar manner, albeit on land, to great success.

Tied in with offboard sensor networks, submarines loaded with ER-S missiles might be able to conduct more general anti-missile defense missions, as well. For instance, a submarine would offer a new and different way to position such a capability closer to enemy territory, and potentially without their knowledge, from where boost-phase intercepts might be attempted. Missiles, especially larger ballistic types, are particularly vulnerable in the boost phase after launch. However, taking advantage of that has historically been complicated by the fact that the launch points are generally expected to be in more heavily defended areas.

If ER-S can also be employed as a hypersonic surface-to-air missile, it would give submarines armed with them additional operational flexibility. A VPM-equipped Virginia class submarine could also carry ER-Ss as just one part of a mixed ordnance load. VPM tubes are designed to accommodate a variety of munitions, including Tomahawk land-attack cruise missiles and Intermediate-Range Conventional Prompt Strike (IRCPS) hypersonic missiles.

In the missile defense context, the submarine with mid-course ballistic missile and/or hypersonic missile interceptors onboard could provide a more forward launch point for midcourse interception of these weapons. This would provide another layer of defense, especially in anti-access combat scenarios, allowing for the traditional missile defense layer, farther to the rear, to deal with whatever breaks through.

This all sounds great, but there is one problem with actually using this kind of capability in a sustained operational context. Firing off a larger interceptor from a submarine gives off a huge signature — infrared, radar, and acoustic. This is exactly what submarines operating forward try to avoid at nearly all costs. So how exactly this would be mitigated is unclear at this time. Clearly, there is a risk-reward calculus to all operations, but having a hugely valuable asset loaded with sensitive technologies and lives give away its position deep in enemy territory to shoot down a plane or missile would be a choice that would have to be made very carefully. The submarine could have a long way to run to safer territory if its presence were detected.

If nothing else, ER-S would create a submarine-based anti-air capability, and its very presence would impact adversary anti-submarine warfare playbooks. When it comes to chasing down U.S. submarines from the air, the hunted could now shoot back.

The Navy does still appear to be relatively early on in the process of outlining the NMM concept, let alone moving down a path that could lead to an operational capability. The requirements for NMM, including the submarine-launched capability, could well evolve further down the line, or even be truncated to focus first on a lower-risk spiral. As it stands now, the Navy is asking for $311 million to support NMM development in Fiscal Year 2027, which it says is a “new start” effort.

“The Department [of the Navy] is implementing diverse procurement strategies to enable rapid acquisition,” the service’s budget documents also note. “These will include the use of Other Transaction Authorities, ‘Marketplace’ acquisition platforms, and alternative concepts to increase supply and suppliers in addition to traditional FAR-based procurement strategies.”

Still, the NMM plan that the Navy has outlined now shows that it is pursuing a significant leap in anti-air capability that will be employed across its fleets, including on certain Virginia class submarines.

After more than 42 years of service as one of America’s most potent power-projection platforms, the nuclear-powered submarine USS Georgia has returned home from operations for the final time ahead of its retirement. The boat is one of four Ohio class nuclear-powered guided missile submarines, or SSGNs. The SSGNs are some of the most capable and in-demand submarines in the U.S. Navy’s inventory today, but all are set to leave service before the end of the decade.

The USS Georgia returned to its homeport of Naval Submarine Base Kings Bay, Georgia, on Monday. The boat is scheduled to be officially inactivated on July 31, the first step on a long road through retirement that is set to end with it being recycled.

Georgia was first commissioned as an Ohio class nuclear ballistic missile submarine, or SSBN, in 1984. It was the last of the four Ohio class boats to be converted into a conventionally armed SSGN, returning to the fleet in its new form in 2008. However, it was used as the main testbed for proving out the concept initially, as you can read about in much more detail in this past TWZ feature.

The Ohio class SSGNs are most widely known for their ability to carry up to 154 Tomahawk land-attack cruise missiles. However, they typically only carry around 100 of these weapons – a still impressive amount – and are actually highly capable multi-mission platforms. These boats can be fitted with up to two dry deck shelters, for deploying special operators underwater, including in mini-submarines, as well as uncrewed platforms. They are also equipped to act as discreet underwater intelligence fusion nodes and command centers.

This unique mix of capabilities has led the four converted Ohios to become among the most heavily tasked submarines in the Navy. The public presence of one of these SSGNs, as well as their SSBN cousins, in any region of the world sends powerful signals to opponents, as well as allies and partners. Over the years, they have made somewhat regular appearances during spikes in geopolitical friction globally.

USS Georgia, specifically, has been used for this purpose on several occasions in the past, especially in the Middle East. In late 2020 and early 2021, Georgia made rare publicized trips on the surface through the Strait of Hormuz during periods of particular tension with Iran. In May 2021, Iranian boats harassed the submarine and its escorts during one of these transits, prompting a U.S. Coast Guard patrol boat to fire warning shots.

The USS Georgia is also very likely to have been the submarine that fired more than two dozen Tomahawks at the Iranian nuclear facility at Isfahan as part of Operation Midnight Hammer in 2025. Whether or not it took part in subsequent strikes on Iran as part of Operation Epic Fury this year is unclear.

Despite what the Ohio class SSGNs continue to bring to the table, the Navy currently plans to inactivate all of them over the next three years. The plan had previously been to have all of these boats out of active service by 2028. This timeline has now been just slightly extended, with the USS Ohio, USS Florida, and USS Michigan set to follow Georgia into retirement in Fiscal Years 2027, 2028, and 2029, respectively. USS Ohio is also notably the lead boat in the class and, by extension, the oldest, having entered service in 1981.

As it stands now, there is no direct replacement for the Ohio SSGNs in the Navy’s shipbuilding pipeline. The service does have a number of Virginia class attack submarines capable of supporting special operations missions in service now and is planning to acquire enlarged Block V subvariants. Each Block V will feature what is known as the Virginia Payload Module (VPM), which gives the boat four additional larger vertical launch tubes, and will really make it more of an SSGN. Between the VPM and the existing launch tubes carried over from the Block IV design, these submarines will be able to carry up to 40 Tomahawk missiles at a time. The VPM tubes will also be able to accommodate the forthcoming Intermediate-Range Conventional Prompt Strike (IRCPS) hypersonic missile. However, no version of the Virginia class is expected to provide the same level of capability, at least in some regards, as is found on the Ohio SSGNs, based on what is publicly known. The first Block V Virginia class submarine with the VPM is not expected to enter service until 2028.

The Navy is also in the process of replacing its Ohio SSBNs with new Columbia class types. There has been talk in the past of acquiring new “Large Payload Submarines,” possibly based on the Columbia design, as a more direct replacement for the Ohio SSGNs. However, the Columbia class program has suffered delays and cost growth, and the priority remains on getting the new SSBNs into service. It is critical for those boats to be delivered on a tight schedule to ensure there is no gap in the ability of the maritime leg of America’s nuclear triad to meet operational requirements.

In the meantime, the USS Georgia is already heading toward retirement and, unless the Navy changes course, the last of these highly capable submarines will be out of active service by 2029.

China’s successful submarine-launched ballistic missile test into the southern Pacific this week was more than a routine military exercise. It provided Beijing with a rare opportunity to validate one of the most sensitive aspects of its nuclear deterrent its ability to command, communicate with and potentially deploy nuclear-armed submarines while remaining undetected.

The test, carried out on Monday, involved a ballistic missile launched from a strategic nuclear-powered submarine and has drawn close scrutiny from regional governments and defence analysts. While Chinese officials described it as a standard military drill conducted in accordance with international law, experts say it marks another step in China’s effort to build a more credible and survivable nuclear force.

Why submarine missile tests matter

Unlike land-based nuclear missiles, submarine-launched ballistic missiles (SLBMs) are designed to ensure a country can retaliate even if its territory comes under nuclear attack. This “second-strike capability” forms one of the central pillars of nuclear deterrence.

Analysts say the test was not solely about assessing missile performance. It also allowed Chinese military leaders to evaluate the complex command-and-control systems needed to operate nuclear submarines while they remain hidden beneath the ocean.

Maintaining secure communications with submarines without revealing their position is among the most technically demanding aspects of any nuclear arsenal.

Collin Koh, a security expert at Singapore’s S. Rajaratnam School of International Studies, said Beijing would likely have been evaluating communications, operational procedures and submarine performance alongside the missile itself.

A key part of China’s nuclear modernization

Regional defence experts believe the missile was launched from one of China’s Type-094 nuclear-powered ballistic missile submarines (SSBNs), although Beijing has not officially identified the vessel.

China has steadily expanded its nuclear capabilities over the past decade, developing what military planners describe as a complete “nuclear triad”—the ability to launch nuclear weapons from land, sea and air.

The submarine component is viewed as increasingly important because it offers a survivable retaliatory force if China’s land-based missile sites were destroyed during a conflict.

According to previous U.S. defence assessments, China has already begun near-continuous deterrence patrols using its SSBN fleet, joining the United States, Russia, Britain and France in maintaining an at-sea nuclear capability.

Challenges remain

Despite the progress, experts note that China’s submarine force still faces significant operational hurdles.

To threaten the continental United States with its most advanced JL-3 submarine-launched missile, Chinese submarines would likely need to leave the relative protection of the South China Sea and enter the wider Pacific Ocean, where they could be tracked by U.S. and allied anti-submarine forces.

Military analysts say American and allied navies closely monitor Chinese submarines using surveillance aircraft, underwater sensor networks and naval patrols.

China is also developing a quieter next-generation ballistic missile submarine that could improve its ability to operate undetected.

Regional reaction

The launch prompted criticism from several regional governments.

The United States said China had provided only limited advance notification before the launch and expressed concern over Beijing’s rapidly expanding nuclear arsenal. Japan, Australia, New Zealand and Taiwan also voiced concern following the test.

China rejected the criticism, insisting the exercise complied with international law and was intended solely to safeguard national security and strategic stability.

Beijing has repeatedly argued that its nuclear modernization remains defensive and consistent with its longstanding policy of not being the first to use nuclear weapons.

Analysis: A signal beyond the missile

The importance of this test extends beyond the missile itself. It demonstrates Beijing’s growing confidence in the sea-based leg of its nuclear deterrent, an area traditionally dominated by the United States and Russia.

The exercise also reflects China’s broader military modernization strategy under President Xi Jinping, which prioritizes survivable nuclear forces capable of guaranteeing retaliation under any scenario. Even if operational challenges remain—particularly the ability of Chinese submarines to evade increasingly sophisticated Western tracking systems—the test suggests China is moving closer to a fully credible second-strike capability.

Strategically, the launch sends multiple messages. Domestically, it showcases advances in China’s military technology. Regionally, it reinforces Beijing’s determination to protect its security interests. Internationally, it signals that China’s nuclear forces are becoming more sophisticated, mobile and resilient, adding another layer of complexity to strategic competition with the United States and its allies in the Indo-Pacific.

July 9 (UPI) — An Argentine court convicted former Navy Capt. Claudio Villamide and sentenced him to three years of suspended prison time for his role in the 2017 sinking of the submarine ARA San Juan, the country’s deadliest peacetime naval disaster.

The sinking killed all 44 crew members. The submarine was located in late 2018 at a depth of roughly 3,000 feet in the South Atlantic. It has not been recovered.

According to Argentine media reports, the court in Río Gallegos found Villamide guilty Wednesday of aggravated negligence and failing to fulfill the duties of a public official. In addition to the suspended sentence, he was barred from holding public office for six years.

Prosecutors argued that Villamide, who commanded the Argentine Navy’s Submarine Force at the time of the disaster, authorized the patrol mission despite knowing the vessel had serious maintenance deficiencies. The submarine had pending post-repair tests and was subject to a technical diving restriction that was ignored, prosecutors said.

Villamide maintained his innocence throughout the trial, arguing the submarine met operational requirements, and that investigators had not conclusively determined the physical cause of the disaster.

Because the sentence was suspended, Villamide will not serve time in prison.

In a unanimous decision, the court acquitted three other former naval officers charged in the case: former Rear Adm. Luis Enrique López Mazzeo, former Capt. Héctor Aníbal Alonso and former Capt. Hugo Miguel Correa.

Relatives of the victims expressed outrage over the ruling and what they described as the leniency of the only conviction.

According to Argentine newspaper Página/12, many family members believe the verdict fell short of delivering justice because it did not hold the Navy’s top commanders or senior government officials from the time accountable.

Lawyers representing the victims’ families said they will appeal the ruling before Argentina’s Federal Court of Cassation beginning Aug. 21, seeking to overturn the acquittals and increase Villamide’s sentence. At the same time, they described the decision as an unprecedented institutional milestone, according to La Nación.

For the first time, an Argentine court ruled that the loss of a military vessel during peacetime was not solely the result of weather conditions, but also of serious human failures and omissions.

Villamide’s defense also rejected the verdict.

His attorneys called the conviction “unusual and unjust,” arguing the trial established there was no direct causal link between the orders issued by naval command and the submarine’s final collapse in the South Atlantic, according to La Opinión Austral.

The defense said it also plans to appeal in an effort to obtain a full acquittal.

The ARA San Juan reported flooding and an electrical fire caused by seawater entering its battery compartment on Nov. 15, 2017. After contact with the submarine was lost, its wreckage, crushed by an implosion, was found about a year later nearly 3,000 feet below the surface of the South Atlantic.

June 24 (Asia Today) — Economic benefits are emerging as a potential deciding factor in Canada’s competition to acquire a new submarine fleet, with South Korea promoting a broad industrial cooperation package to counter a larger economic-impact proposal from Germany.

Canada is preparing to select a preferred bidder for the Canadian Patrol Submarine Project, a program worth as much as 60 trillion won ($39.2 billion).

German shipbuilder TKMS and South Korea’s Hanwha Ocean are the two qualified suppliers remaining in the competition.

Canadian Secretary of State for Defense Procurement Stephen Fuhr said this week that both proposals meet the Royal Canadian Navy’s requirements, according to industry officials.

With the technical assessment effectively completed, the economic and industrial benefits offered by each bidder could become increasingly important in the final evaluation.

Based on publicly disclosed projections, TKMS appears to have proposed the larger economic contribution.

The German company said its proposal could generate 160 billion Canadian dollars in economic activity and add 86 billion Canadian dollars to Canada’s gross domestic product over the life of the program.

It also projected employment totaling more than 650,000 job-years.

Hanwha Ocean said South Korea’s proposal could support more than 22,500 Canadian jobs annually, equivalent to more than 400,000 job-years, and generate approximately 94.1 billion Canadian dollars in cumulative GDP contributions.

Industry officials said the scale and feasibility of the proposed partnerships may be more important than a direct comparison of headline figures.

Hanwha Ocean has established partnerships with more than 100 Canadian companies, universities and other organizations.

HD Hyundai Group has proposed several billion dollars in cooperation across the energy, commercial shipbuilding and naval sectors.

Hyundai Motor Group is also supporting the broader South Korean proposal through Project Beaver, an initiative intended to establish a hydrogen mobility ecosystem in Canada.

The effort is part of a government-backed package that seeks to position South Korea as a long-term industrial and security partner rather than simply a submarine supplier.

Germany is also offering substantial government and industrial support.

TKMS has emphasized its cooperation with Norway, which is jointly developing and acquiring Type 212CD submarines with Germany.

Norway has offered to share experience involving submarine design and maintenance, repair and overhaul systems.

The German proposal also highlights the benefits of integrating Canada into an existing supply and support network among North Atlantic Treaty Organization allies.

Sustainment carries greatest weight

Canada’s evaluation structure places the greatest emphasis on the ability to support the submarines throughout their operational lives.

Sustainment accounts for 50% of the assessment, while the submarine platform itself represents 20%.

Financial considerations account for 15%, with strategic and economic partnerships making up the remaining 15%.

The weighting indicates that Canada’s primary concern is not simply acquiring advanced submarines but ensuring that it can operate and maintain them reliably for several decades.

Some industry observers have cautioned that excessive attention to economic projections could distract from the program’s core defense objectives.

Both South Korea and Germany have proposed major investments, local partnerships and job-creation plans.

Critics say an escalating competition over economic promises could transform a military procurement decision into a broader contest for foreign investment.

The figures presented by the bidders are also based on different assumptions, industries and time periods, making direct comparisons difficult.

The projected employment numbers may include jobs supported for multiple years rather than distinct permanent positions.

“The technological capabilities, delivery competitiveness and industrial cooperation package offered by South Korean shipbuilders are clear strengths,” a South Korean shipbuilding industry official said.

“Both countries are making an all-out effort, so it remains difficult to predict the outcome before the final decision.”

Hanwha Ocean is offering a Canadian version of its KSS-III submarine, a platform developed for and operated by the South Korean Navy.

South Korea has emphasized its shipbuilding capacity and ability to deliver vessels within Canada’s accelerated timetable.

The proposal also includes Canadian participation in construction, maintenance, technology development and supply chains extending beyond the submarine program.

South Korean companies have pursued cooperation with Canadian businesses in steel, automotive manufacturing, artificial intelligence, aerospace, energy and critical minerals.

The package is intended to demonstrate that selecting Hanwha Ocean would produce economic benefits across multiple regions and industries in Canada.

TKMS, meanwhile, is offering a submarine supported by the German and Norwegian governments and an established European defense network.

Its proposal stresses operational compatibility with NATO allies, shared training and access to a multinational submarine supply chain.

Canada is expected to announce its preferred approach between late June and early July. Industry officials said a decision could come as early as this week.

June 17 (Asia Today) — Canada is expected to select a preferred bidder within 30 days for a major submarine procurement program, narrowing the competition to South Korea’s Hanwha Ocean and Germany’s Thyssenkrupp Marine Systems.

The Canadian Patrol Submarine Project calls for the acquisition of up to 12 conventionally powered submarines to replace the Royal Canadian Navy’s four aging Victoria-class vessels.

The acquisition, infrastructure and long-term maintenance program has been estimated by South Korean industry officials at at least 60 trillion won, or about $39.7 billion. Some estimates place its potential value over several decades as high as 120 trillion won, or about $79.4 billion.

Stephen Fuhr, Canada’s secretary of state for defence procurement, said Ottawa expected to choose a preferred bidder within 30 days, according to Politico.

The selection would grant one bidder the right to enter detailed negotiations with the Canadian government, although it would not constitute a final contract award.

Canada previously identified Hanwha Ocean and Germany’s Thyssenkrupp Marine Systems as the two qualified suppliers for the program.

The contest has entered its final stage as South Korea promotes a package combining submarine construction, government-backed financing and broader industrial cooperation.

Canadian procurement chief visits South Korea

Fuhr visited Hanwha Ocean’s shipyard in Geoje, about 205 miles southeast of Seoul, on Feb. 2 with Canadian government and business representatives.

He toured the shipyard’s assembly facilities and automated production equipment and boarded the ROKS Jang Yeong-sil, the first 3,000-ton submarine in South Korea’s Dosan Ahn Changho Batch-II class, while it was undergoing sea trials.

Fuhr was accompanied by Hanwha Ocean Chief Executive Kim Hee-cheul and senior South Korean officials.

He later visited the South Korean Navy’s Submarine Force Command in Jinhae to examine its training, logistics and maintenance systems.

Hanwha Ocean said the visit allowed the Canadian delegation to assess South Korea’s submarine manufacturing capacity and its ability to provide long-term maintenance and operational support.

Canada seeks submarines for three oceans

Canada wants its future fleet to operate across the Atlantic, Pacific and Arctic oceans while maintaining interoperability with the United States and other allies.

Its requirements include long range, extended endurance, under-ice capability and reliable maintenance support.

Hanwha Ocean is offering a version of South Korea’s Dosan Ahn Changho-class submarine, also known as the KSS-III.

The company has emphasized that the platform is already in production and can be delivered more quickly than a newly developed design. It has also proposed cooperation with Canadian universities, shipyards and defense companies.

Thyssenkrupp Marine Systems is offering the Type 212CD submarine, a new design being developed for Germany and Norway.

The German bidder has highlighted its long-standing relationships within NATO, European defense supply chains and proposed investment in Canadian industry.

Germany and Norway have also reportedly examined changes to their own production schedules to make earlier delivery slots available to Canada.

Industrial benefits could determine outcome

Canada has made domestic jobs, industrial investment and long-term economic benefits central elements of the procurement.

The government has said work associated with the submarines should strengthen Canada’s marine and defense industries throughout the fleet’s operational life.

South Korea has therefore sought to expand its proposal beyond the construction of submarines.

Canadian officials have discussed potential South Korean investment in Canada’s automotive and transportation industries, according to people familiar with the negotiations.

South Korean companies have responded by exploring a hydrogen-powered commercial vehicle and fueling network rather than committing immediately to a conventional automobile assembly plant.

Hyundai Translead, Hyundai Motor Group’s North American trailer manufacturing subsidiary, has signed a dealership agreement with Canadian commercial vehicle dealer Breadner Trailers for Hyundai’s XCIENT hydrogen fuel-cell trucks.

The trucks have accumulated more than 1 million miles, or 1.6 million kilometers, of commercial driving in North America, according to Hyundai.

Glenn Copeland, president of Hanwha Ocean’s Canadian subsidiary, previously said Hyundai Motor Group had presented an initial proposal to Canadian officials for a hydrogen freight transportation corridor.

The plan could support Canada’s transportation decarbonization policies while adding a civilian industrial component to South Korea’s submarine offer.

Seoul prepares financial support

The South Korean government and state financial institutions are also preparing export financing to support the bid.

The Korea Trade Insurance Corp. and the Export-Import Bank of Korea have expanded financing programs for major overseas projects in defense, nuclear power and other strategic industries.

South Korean officials have said as much as 100 trillion won, or about $66.1 billion, from a broader export financing initiative could be made available for defense and nuclear energy projects. The amount does not represent financing committed exclusively to the Canadian submarine program.

Hanwha Ocean has also sought to demonstrate the strength of its domestic supply chain.

At the World Defense Show in Riyadh in February, the shipbuilder signed cooperation agreements with 11 South Korean defense and submarine equipment companies, including LIG Nex1, Hanwha Aerospace, Kolon Spaceworks, KTE and Firstec.

Hanwha Ocean says more than 80% of the components used in its proposed submarine can be supplied domestically.

A South Korean defense industry official said the final decision would depend not only on submarine performance but also on financing, delivery schedules, maintenance support and benefits for Canadian industry.

“Canada’s submarine project is more than a weapons sale,” the official said. “The remaining competition will be decided by which bidder can offer the most credible combination of capability, delivery and long-term industrial cooperation.”

A new type of submarine that appears to lack a traditional sail has emerged in China. The same shipyard launched a smaller ‘sailless’ submarine — a technology demonstrator — eight years ago. More recently, a top Chinese shipbuilding conglomerate put forward a concept for an uncrewed underwater vehicle (UUV) with a broadly comparable hullform. Designs of this kind can offer benefits in terms of speed, maneuverability, and reduced acoustic signature, but also have major drawbacks.

TWZ has obtained imagery of the submarine in question at JN (Jiangnan) Shipyard in Shanghai on June 1, as seen at the top of this story and below, from Vantor (previously Maxar Technologies). The boat, the name and/or designation of which are currently unknown, first appeared there sometime at the end of May, according to Naval News. That outlet was first to report on this development.

From the imagery, the submarine does not have a traditional sail. However, the exact shaping of what is present is also not entirely clear from the view that is currently available. As noted, JN Shipyard is known to have built at least one other ‘sailless’ submarine in the past, which we will come back to later on.

Writing for Naval News, undersea warfare analyst H.I. Sutton has assessed the design to be roughly 394 feet (120 meters) long and to be between 33 and 36 feet (10 and 11 meters) wide. What its intended missions might be are unknown, but this is certainly larger than common diesel-electric submarines (SSK) and even longer than most nuclear fast attack submarines. For comparison, variants of China’s Type 093 nuclear-powered attack submarine (SSN), some of the most modern submarines in People’s Liberation Army Navy (PLAN) service today, are approximately 356 to 360 feet (108 to 110 meters long) and 36 feet wide. The official stated length and width of the U.S. Navy’s Virginia class SSNs, across all existing subvariants, are 377 feet (114.8 meters) and 34 feet (10.36 meters), respectively.

We can also see that the submarine at JN Shipyard has an X-form rudder configuration, something that first appeared on a submarine in China in 2024. This offers advantages over cruciform stern arrangements with horizontal and vertical rudders when it comes to maneuverability, efficiency, and safety.

An X-shaped stern is a feature now further associated with a next-generation Chinese attack submarine design commonly, but still unofficially, referred to as the Type 095. Naval News also reported today on the recent launch of what may be another Type 095, which has a traditional sail, at the Bohai Shipyard in Huludao, hundreds of miles to the north of Shanghai. This appears to have caused some confusion online, with some mistaking the boat at Bohai for the ‘sailless’ type.

The newly emerged submarine at JN Shipyard may also have a shrouded propulsor, which could be a pumpjet type. Pumpjets offer further benefits for quieter operation, especially at higher submerged speeds.

The absence of a traditional sail is still the most notable aspect of the new submarine at JN Shipyard. Omitting a large structure sticking out of the top of the hull helps significantly with streamlining the overall design. Eliminating that drag can allow greater optimization for speed and maneuverability while submerged. It can also help make the submarine quieter and, by extension, harder to detect, even while transiting through an area at higher speeds. This can be especially useful when racing out to threats, even those far away.

Not having a traditional sail could impose certain design constraints. Traditionally, naval submarines have used their sails to mount periscopes and other sensor masts, as well as extendable communication antennas and snorkels to help cycle air without fully resurfacing. That is space that can be used for other purposes, including launchers for countermeasures and general storage.

Above all else, while running on the surface, the sail is key for general navigation and situational awareness. It can also provide an elevated position for local force protection or supporting vertical replenishment (VERTREP) operations. If sufficiently hardened, it can even break through feet of ice during operations in and around the polar regions.

The lack of a sail might reflect a focus on seabed operations far from the surface where mast deployment and other considerations might be less pressing. At the same time, the design’s features could just as easily be centered on improving performance, including the ability to make transits as quickly as possible during blue water operations. It could also offer benefits for shallow-water operations, though we have noted that, overall, it is very large compared to SSKs.

As mentioned, a smaller ‘sailless’ submarine had already emerged at JN Shipyard in 2018. H.I. Sutton previously estimated that design to be around 150 feet (45 meters) long and 15 feet (four to four-and-a-half meters) wide. That submarine also had a non-X-shaped rudder arrangement and what appeared to be an unshrouded propeller. The exact reasons for building that boat and how it has been utilized over the years remain unknown, but it would have at least provided a testbed and technology demonstration platform to explore this design concept, and potentially other capabilities. Whether it was designed for crewed or uncrewed operation, or to be optionally crewed, is not clear, either. The same is true of this new submarine, though it seems unlikely it is uncrewed.

At the Zhuhai Airshow in 2024, the state-run China State Shipbuilding Corporation (CSSC) did show a model of an unprecedentedly large, diesel-electric UUV. Its overall design was highly reminiscent, at least in broad strokes, of JN Shipyard’s original ‘sailless’ submarine, as TWZ noted at the time. JN Shipyard is one of many subsidiaries of CSSC.

CSSC said at the time that the drone submarine could be configured to perform a wide array of missions, including launching attacks on enemy vessels, laying mines, supporting special operations forces, and serving as a mothership for smaller uncrewed underwater vehicles (UUV). You can read more about all of this here.

Other shipyards and navies around the world have explored low-profile submarine designs in the past, but designs have generally been consigned to the world of paper concepts and limited experimentation. The U.S. Navy, for instance, previously tested a Large Scale Vehicle Range (LSVR) subscale demonstrator submarine with a novel sail structure. The Navy’s Acoustic Research Detachment (ARD) conducted that work in a lake in Bayview, Idaho.

In 2021, the Navy also notably put out a contracting notice calling for concepts for inflatable sail structures, which could combine the benefits of traditional sails and low-profile designs. What degree of work the service may have conducted since then on this Inflatable Deployable Sail System (IDSS) is unclear, but it underscores how important a sail is for general operations on the surface.

The PLAN’s submarine force otherwise continues to grow in terms of capability and capacity, with an increasing number of more modern types. U.S. officials have openly said in the past that the quality of newer Chinese submarines has been getting closer in parity to American designs. All of this is further underscored by the recent appearance of the other new submarine at Bohai. In addition to new nuclear-power designs, China is also understood to be developing at least one design with a hybrid nuclear/conventional propulsion system, referred to as the Type 041 or Zhou class. The first known example of the Type 041 came to light after it looked to have sunk in a shipyard in 2024.

Greater use of nuclear propulsion promises to extend the reach of Chinese submarines in the Pacific and beyond, and is clearly part of the PLAN’s larger vision for naval power projection going forward.

“The PLA Navy is executing a significant strategic shift from diesel-electric to all-nuclear construction, representing a fundamental departure from historical construction patterns,” U.S. Navy Rear Adm. Mike Brookes, head of the Office of Naval Intelligence, wrote in prepared remarks ahead of a hearing before members of the U.S.-China Economic and Security Review Commission in March.

Brookes also highlighted how the hybrid Type 041, specifically, could offer “greater endurance, potentially filling regional patrol and presence missions more economically than full-size SSNs [attack submarines] and SSGN [guided missile submarines.”

China has significant demands for naval presence, in general, especially to assert its extensive and widely disputed maritime territorial claims in the South China Sea and elsewhere. The PLAN continues to expand the scale and scope of its combat fleets, overall, at a pace that far exceeds that of other navies globally. This includes the U.S. Navy, where the disparity has become increasingly concerning, as TWZ routinely highlights.

More remains to be learned about the newly emerged submarine at JN Shipyard, but it could point to new low-profile designs without traditional sails, possibly to act as the PLAN’s underwater high-speed interceptor, being part of China’s larger future submarine future.

May 24 (Asia Today) — South Korea is preparing to publicly unveil a development roadmap for a nuclear-powered attack submarine program after the successful Pacific deployment of the domestically built Dosan Ahn Chang-ho submarine, according to military and defense officials.

The move signals Seoul’s effort to strengthen what officials describe as the strongest conventional strategic deterrence available to a non-nuclear weapons state in response to North Korea’s advancing nuclear and missile capabilities and growing maritime competition in the region.

Senior military officials said the Ministry of National Defense and the Defense Acquisition Program Administration have completed technical reviews for a South Korean nuclear-powered submarine program and are now coordinating with related ministries, including the Foreign Ministry, on a diplomatic and regulatory strategy.

The report follows the recent Pacific deployment of the 3,000-ton Dosan Ahn Chang-ho submarine, which sailed about 14,000 kilometers, or 8,700 miles, from Jinhae through Guam and Hawaii using only domestically developed lead-acid batteries, diesel engines and an air-independent propulsion system.

South Korean officials said the deployment significantly reduced the need for snorkeling operations, in which submarines surface or raise air intake masts to recharge batteries, and demonstrated the vessel’s long-duration underwater operational capability and hull durability.

Officials also said the submarine successfully demonstrated stable operation of its submarine-launched ballistic missile vertical launch system in rough Pacific conditions. The Dosan Ahn Chang-ho class is the world’s first diesel-electric submarine class equipped with vertical launch tubes for submarine-launched ballistic missiles.

Defense experts said the mission simultaneously highlighted the operational limitations of conventional diesel submarines and the strategic advantages of nuclear propulsion.

While diesel-electric submarines must operate at relatively slow underwater speeds to maintain endurance, nuclear-powered submarines can remain submerged for much longer periods and travel underwater at speeds exceeding 40 kilometers per hour, allowing broader operational flexibility, officials said.

The foreign affairs and security publication The Diplomat reported Thursday that South Korea’s pursuit of a nuclear-powered submarine would become “a major test case of non-nuclear deterrence” for a country that does not possess nuclear weapons.

Chung Sung-chang, head of the Korea Nuclear Strategy Forum and a senior researcher at the Sejong Institute, said the submarine under discussion would be a non-nuclear attack submarine that would not carry nuclear weapons.

Chung said South Korea plans to retain the hull design and submarine-launched ballistic missile strike capability proven through the Dosan Ahn Chang-ho program while replacing the diesel propulsion system with a small nuclear reactor.

He said South Korea should first publicly present its nuclear submarine development roadmap before negotiating a bilateral nuclear submarine cooperation agreement with the United States and securing approval from the U.S. Congress.

Chung also said Seoul would need a separate agreement with Washington to secure low-enriched uranium fuel for naval reactors derived from downgraded highly enriched uranium.

Officials are reportedly studying the AUKUS security partnership among the United States, Britain and Australia, under which Australia received access to nuclear-powered submarine technology while remaining within the international nonproliferation framework.

South Korean officials said the success of the Dosan Ahn Chang-ho deployment demonstrated that the country’s technical preparations for a future nuclear-powered submarine program had reached a mature stage, shifting the focus toward diplomatic negotiations and international coordination.

May 15 (Asia Today) — South Korea may announce a basic plan for acquiring nuclear-powered submarines as early as this month, officials and diplomatic sources said Friday.

According to foreign policy and security sources, the government is preparing a “Korean nuclear-powered submarine basic plan” that would outline its core principles and a timeline for acquisition.

A Defense Ministry official said the plan is being developed in coordination with relevant agencies but said the exact schedule could not be confirmed.

The official also said it has not been decided whether the Defense Ministry will lead the announcement.

Although no specific date has been set, some observers expect the plan could be released before the Shangri-La Dialogue, an Asian security forum scheduled to take place in Singapore later this month.

The plan is expected to include the defensive nature of the submarines, their missions and roles, a detailed timeline, fuel procurement and financing plans and South Korea’s commitment to complying with the Nuclear Non-Proliferation Treaty.

If announced, the plan would mark a formal declaration of the government’s intention to pursue nuclear-powered submarines.

A joint fact sheet released after a recent South Korea-U.S. summit said the United States had approved South Korea’s construction of nuclear-powered submarines and would work closely with Seoul, including on fuel procurement.

Defense Minister Ahn Gyu-back recently visited the United States and discussed cooperation on nuclear-powered submarine construction with U.S. defense officials.

May 8 (Asia Today) — South Korea’s first domestically designed 3,000-ton submarine has completed a long-distance Pacific deployment as Seoul seeks to strengthen its bid for Canada’s next-generation submarine procurement program.

The South Korean Navy said the Dosan Ahn Chang-ho departed Pearl Harbor-Hickam in Hawaii on Friday with two Canadian Navy submarine personnel aboard and is scheduled to arrive at Esquimalt Harbor in Victoria, British Columbia, in late May.

The submarine left Jinhae Naval Base on March 25 and traveled through Guam and Hawaii before heading toward Canada.

The deployment is seen as a major test of the submarine’s endurance, reliability and operational performance, as South Korean shipbuilders compete for Canada’s submarine project, estimated at about $42 billion.

The Dosan Ahn Chang-ho is expected to travel up to about 18,600 miles round trip, much of it independently. Defense officials say the mission is intended to demonstrate the submarine’s long-range capabilities, quiet operation, onboard living conditions and air-independent propulsion system.

Two Canadian Navy personnel, Maj. Britany Bourgeois and Petty Officer Jake Dixon, joined the submarine for the final leg from Hawaii to Canada.

The submarine is expected to take part in joint training with the Canadian Navy after arriving in late May. The exercises are expected to focus on anti-submarine warfare and interoperability.

Canadian officials are expected to assess whether the South Korean submarine meets key requirements for long-range patrols and operations near Arctic waters.

The Dosan Ahn Chang-ho will later participate in the U.S.-led Rim of the Pacific exercise, known as RIMPAC 2026, alongside South Korea’s next-generation Aegis destroyer Jeongjo the Great.

South Korea’s participation is expected to highlight its growing ability to operate with U.S. and allied naval forces in complex maritime environments.

Canada’s submarine procurement program calls for the acquisition of 12 submarines. South Korean shipbuilders Hanwha Ocean and HD Hyundai Heavy Industries are competing against Germany’s Thyssenkrupp Marine Systems for the contract.

Defense analysts say the Pacific deployment gives South Korea an opportunity to demonstrate proven operational capabilities directly to Canadian officials rather than relying only on written proposals or technical specifications.

The Dosan Ahn Chang-ho is the lead vessel of South Korea’s KSS-III Batch-I class. The submarine has an underwater displacement of about 3,700 tons, is 83.5 meters long and was designed and built in South Korea.

South Korean defense officials say the deployment marks a milestone for the country’s submarine program and reflects the expansion of the Navy’s operating range from coastal waters to the open ocean.

If South Korea wins the Canadian contract, it would mark the largest single defense export deal in the country’s history.
