June 25 (Asia Today) — A South Korean civic leader proposed creating a satellite communications network modeled on SpaceX’s Starlink to provide outside information to people in North Korea.

Jang Man-soon, chairman of the Committee for Ten Million Separated Families and a co-chair of Citizens’ Solidarity for ONE KOREA, called the proposed system “Korea Link.”

“If we place a system similar to Starlink over North Korea, we could inform North Koreans who have access to approximately 8.5 million mobile phones about the realities and conditions in South Korea,” Jang said during an interview Thursday at the National Assembly in Seoul.

The figure was Jang’s estimate and could not be independently confirmed.

Jang said the network could communicate the importance of freedom to North Korean residents and correct historical accounts and information distorted by the North Korean government.

He said it could also help North Koreans develop pride in the goal of Korean unification.

Jang argued that a new means of communication is necessary because traditional methods of reaching North Koreans, including radio broadcasts and border loudspeakers, have become increasingly restricted.

He said North Korean leader Kim Jong Un’s “two hostile states” policy is partly intended to isolate residents from outside information.

“North Korea is at a disadvantage in politics, economics, culture and military power, so the government is trying to block outside information from reaching its people,” Jang said.

Jang also discussed the declining prospects for families separated by the division of the Korean Peninsula and the 1950-53 Korean War.

“The wish of separated families is no longer simply to reunite with relatives,” he said. “It is to set foot in their hometowns.”

Many first-generation separated family members are now in their 90s, and few still have living parents in North Korea, he said.

“Their greatest wish is to visit their hometowns before they die,” Jang said.

He warned that public awareness of separated families is fading with each generation.

Jang called for expanded unification education for young people, opportunities to hear testimony from first-generation separated family members and educational visits to areas near the inter-Korean border.

“The reality is that only about half of the public now believes unification is necessary,” he said. “We are preparing various activities, including youth education, testimony from first-generation separated families and visits to border regions.”

Jang urged the South Korean government to participate in practical projects intended to support North Korean residents and preserve awareness of freedom and unification.

“If we view the people of North Korea as members of the same nation, I hope the government will participate in the practical plans we are pursuing,” he said.

“We must work together to establish a foundation that will allow future generations to understand the meaning of genuine freedom in the Republic of Korea.”

KC-135 Tanker Spotted With New Satellite Communications Antenna

A U.S. Air Force KC-135 tanker appeared in the United Kingdom this weekend with a new antenna on top of the rear of the fuselage. The service has several efforts underway to improve the communications networking capabilities of all of its tankers and cargo planes, including ones that leverage Starshield, the government-focused cousin of SpaceX’s Starlink. This has become an especially critical priority for future survivability and effectiveness of the aging KC-135 fleet.

Aviation photographer Alessandro Ledda, who goes by Aerographist on Instagram, caught the KC-135 in question at RAF Mildenhall yesterday. The base is a major hub for U.S. Air Force operations in the United Kingdom. It has been utilized to support recent operations against Iran, as have other RAF facilities.

Ledda told TWZ that online flight tracking data says this particular KC-135 is serial number 63-7976, but that this might not be correct. The plane is largely devoid of markings, preventing easy confirmation. Two years ago, the Air Force’s Air Mobility Command (AMC) began removing serial numbers and other unique identifying markings from tankers and other aircraft as an operational security measure, as you can read more about here.

Ledda also told us that this is the first time he has seen a KC-135 with the new dorsal antenna, despite regularly photographing tankers of this type at Mildenhall. The base is home to the Air Force’s 100th Air Refueling Wing, which flies the KC-135, but is also a regular staging point for temporary deployments and a stop-over for aircraft just passing through.

A picture of the same antenna on top of a KC-135 had emerged online in April, but where and when it was taken are unclear. This may or may not be the same aircraft seen at Mildenhall this weekend. It is unknown how many Air Force KC-135s may have received this modification so far, and TWZ has reached out to the Air Force for more information. At the beginning of Fiscal Year 2026, the Air Force had 368 KC-135s in inventory, in total. At least a portion of that fleet is set to remain in service through 2050.

The antenna has a very roughly trapezoidal shape with a mostly flat top. There is a single small blade that sticks up at the rear, as well. The size and shape are broadly reflective of ‘hump’ style antennas associated with high-bandwidth satellite communications (SATCOM) suites seen on large military and commercial aircraft. In both pictures we have seen of this installation on the KC-135 so far, the new antenna is also mounted right behind a much smaller existing platter-shaped type typically used to support ultra-high-frequency SATCOM links.

Back in April, the possibility was raised that the new antenna for the KC-135 could be tied to Airlift/Tanker Open Mission Systems (ATOMS) and/or its successor, MAF NEXUS, both developed by the Sierra Nevada Corporation (SNC). MAF here stands for Mobility Air Forces, a collective term for the Air Force’s tanker and airlifter fleets, and the personnel that support them.

ATOMS is “a Starshield-based BLOS [beyond line of sight] satcom system SNC has been installing on a handful of [KC]-135s, [C]-17s, [KC]-46s, [C]-130s. Saw a C-17 getting it last week in Dayton,” Aviation Week‘s Brian Everstine wrote on X, speaking generally, in a thread discussing the first picture of the new antenna for the KC-135 that had emerged. ATOMS is “now transforming to Air Mobility Commands [sic] ‘MAF Nexus.’”

As noted, Starshield is a more secure, government-centric offshoot of SpaceX’s Starlink space-based network. Starshield and Starlink have been in increasing use across the U.S. military on aircraft, as well as warships and in various contexts on the ground, for years now, as TWZ has explored on several occasions in the past.

The size and shape of the antenna on the KC-135 at Mildenhall is, broadly speaking, in line with commercial Starlink antennas used on airliners and other civilian aircraft.

“The SNC solution for ATOMS, originally provided as a Quick Reaction Capability (QRC) in just six months, delivers enhanced situational awareness through multidomain networking and datalink,” SNC had explained in a press release in August 2025. “The system’s ability to provide a Common Operating Picture improves data interpretation and bolsters decision advantage, strengthening AMC’s effectiveness by leveraging multiple communications paths and sensors to seamlessly share data.”

That release followed the conclusion of the Air Force’s Mobility Guardian 2025 exercise, in which ATOMS “played a pivotal role” by “demonstrating its ability to provide seamless data management and communications solutions on multiple aircraft platforms, including the C-17, KC-135, KC-46 and C-130, as well as numerous ground nodes.”

The Air Force’s 2027 Fiscal Year budget request highlights at least two other potentially relevant communications upgrade efforts for the service’s KC-135, specifically, which could also make use of Starlink/Starshield.

There is the “Hybrid SATCOM capability,” which involves “the employment of Multi-Band, Multi-Orbit SATCOM terminals to switch between different government and commercial constellations,” according to official budget documents. This is tied to another project called MAF Connectivity focused on developing a “path forward as the tanker needs to be able to connect to the Joint fight to close kill chains and logistics chains.”

For MAF Connectivity, “possible capabilities include, but are not limited to, intelligent gateways, antennas, radios, software updates, crew displays, and multiple aperture array housings,” the budget documents also note. An “increment 1 first prototype installation” was also scheduled to be completed in the second quarter of Fiscal Year 2026, which began on January 1 and ended on March 31.

The antenna could be part of a different effort, as well. The Air Force has fielded a number of roll-on/roll-off communications and networking suites for the KC-135 over the years, but in an ad hoc manner and on a relatively limited scale. Last year, the Air National Guard also announced the demonstration of a new communications and data-sharing node packaged inside a heavily modified underwing Multipoint Refueling System (MPRS) pod, but the extent to which that capability may now be available for operational use is unclear. KC-135 and KC-46 tankers use unmodified MPRS pods to transfer fuel to receivers via the probe-and-drogue method.

As an aside, a Boeing 757 called Trailblazer (N-number N473AP), which defense contractor L3Harris uses as a testbed, also recently emerged with a new elongated dorsal fairing. Trailblazer’s new addition is similar in some broad strokes, but also distinctly different from the antenna seen on the KC-135 at Mildenhall this weekend. One of L3Harris’ major business areas is satellite communications systems, including for the U.S. Air Force. TWZ has reached out to the company for more information about this development.

For years now, the Air Force has been trying to more deeply integrate new communications and networking capabilities onto the KC-135, as well as other tankers and aircraft across the MAF. Senior service officials have also described this as a gateway to enabling other new capabilities down the road, including ones to help better protect tankers and airlifters from future threats. TWZ has previously highlighted this as a path to airborne control for “loyal wingman” type drones and other uncrewed aerial systems, something the Air Force has already been experimenting with to differing degrees.

“I gotta keep modernizing the tanker force,” Air Force Lt. Gen. Rebecca Sonkiss told TWZ and others at a roundtable at the Air & Space Forces Association’s annual warfare symposium in February. “If I was going to parcel out the things we care about in that, though, it’s connectivity and survivability. So those are the things that we really care about in that effort.”

“There’s various ways to get after survivability,” she continued. “It starts with being connected so that you have battlespace awareness, and then it continues on to how do we protect those assets.”

Sonkiss’ official title is Deputy Commander of AMC. However, she has been serving as the interim head of the command since her predecessor, Gen. John Lamontagne, became Vice Chief of Staff of the Air Force in January.

“The single biggest contributor to survivability in a big airplane is connectivity. The biggest contributor is not having a 12-hour-old Intel brief that you’re relying on to get you through the mission,” retired Air Force Gen. Michael “Mini” Minihan, who led AMC from October 2021 to November 2024, told TWZ in an interview in February, as well. “So real-world updates, real-time updates, just like our fighters and our bombers enjoy. Battle management that gets after maneuver and not just kill chain. Those things matter.”

“The reality is that the car I rented right now, driving from the airport to my hotel room, has more connectivity in it than the overwhelming majority of the mobility fleet. So connectivity matters,” he also told us at that time.

New communications and networking suites could enable AMC’s KC-135, as well as the rest of the command’s fleets, to serve as essential ‘translators’ between disparate networks and waveforms in the future. Providing a link between low probability of interception/low probability of detection (LPI/LPD) datalinks that stealthy aircraft use, such as the Multifunction Advanced Data Link (MADL) and Intra-Fighter Data Link (IFDL), and more general-purpose ones, would be especially valuable. IFDL is currently only found on the F-22 Raptor, while all variants of the F-35 fighter (and future B-21 Raider bombers) use MADL, and the two cannot ‘talk’ to each other directly, which has long created challenges. Upgraded tankers could serve as important parts of a beyond-line-of-sight mesh-like network that incorporates other kinds of line-of-sight links like Link16. In this way, they could help relay data to and from forward battle management and other command and control nodes, including ones in the air.

In addition, improved connectivity stands to provide additional operational and safety benefits across the MAF.

“According to the Air Force, the tankers’ ability to access tactical data links could increase mission success in contested environments by improving survivability, agility, and situational awareness for command-and-control elements and aircrews,” the Congressional Research Service (CRS) wrote in a report published in January. “The connectivity could provide aircrews with such information as potential threats, fuel availability, and safer landing sites. In addition, tanker aircraft could serve as a backup information conduit for other aircraft in a degraded communications environment.”

The points here have become a broader topic of discussion after two KC-135s collided over Iraq in March during the opening weeks of Operation Epic Fury against Iran. One of the aircraft crashed, killing all six onboard. The other tanker involved was able to land in Israel despite suffering severe damage. At the time of writing, the Air Force has not yet shared any official determinations as to the chain of events that led to that fatal incident.

“We should never put mobility crews, especially tanker crews, in a position during combat operations where they have to choose between being seen by everyone, including the enemy, or being seen by no one, including the joint force and civil aviation,” Minihan subsequently wrote in a post on LinkedIn. “Mobility force connectivity now. Write the damn check.”

“Most KC-135s [sic] communications networks are ‘not the type of battle space awareness that shows you where the red is, where the blue is, and the actions that are being taken in real time in a conflict,’”Defense One reported in March, citing an interview with retired Air Force Gen. Jacqueline Van Ovost, who previously served as head of U.S. Transportation Command (TRANSCOM). “All you have is the intelligence you took off with when you got the brief two hours prior to take off.”

All this being said, the Air Force is still years away from integrating more robust communications and networking capabilities onto the entire KC-135 fleet.

“Over the course of about the next six years, you’ll see the full fleet of KC-135s fully connected,” Lt. Gen. David Tabor, Deputy Chief of Staff for Plans and Programs, told members of Congress at a hearing last month.

The appearance of the KC-135 with the added antenna at Mildenhall does point to new progress on key connectivity upgrades for Air Force tankers and airlifters. At the same time, improved communications and networking capabilities are increasingly critical now, and it remains to be seen when they become more commonplace across the KC-135 fleet.

Special thanks again to Alessandro Ledda for sharing the picture of the KC-135 seen at Mildenhall this weekend with us.

Iran’s lakes are vanishing: Satellite images show a deepening water crisis | Environment

For many Iranians, the most immediate threat is no longer just war, but water.

Years of drought, falling rainfall and unsustainable water use have pushed the country into severe water stress, depleting reservoirs, rivers and groundwater reserves. The US-Israel war on Iran has added further strain after reports of damage to desalination plants, pipelines and other civilian water infrastructure in the early weeks of the conflict.

Iran is classified by the World Resources Institute as facing “extremely high” baseline water stress, using more than 80 percent of its renewable water supplies each year.

In this visual explainer, Al Jazeera breaks down Iran’s worsening water crisis and what is driving it.

How Lake Urmia disappeared

One of the most striking examples of Iran’s water crisis can be seen from space.

A time-lapse display of Lake Urmia in northwestern Iran shows how the largest saltwater lake in the Middle East, which covered nearly 6,000sq km (2,300sq miles) in the 1990s, shrunk to just 581sq km (224sq miles), less than 10 percent of its former size.

Consecutive droughts, agricultural water use, river diversion, and groundwater extraction have transformed vast stretches of Lake Urmia into exposed salt flats.

More than 60 dams built on its feeder rivers choked off inflows, while farmers diverted water into irrigation channels and decades of groundwater extraction drained the aquifers below. Rising temperatures accelerated evaporation as precipitation fell.

Lake Urmia is a salt lake in northwestern Iran near Iran's border with Turkey. The lake is between the provinces of East Azerbaijan and West Azerbaijan in Iran, and west of the southern portion of the Caspian Sea. At its full size, it is the largest lake in the Middle East and the sixth largest saltwater lake on earth with a surface area of approximately 5,200 km² (2,000 mile²), 140 km (87 mi) length, 55 km (34 mi) width, and 16 m (52 ft) depth. Lake Urmia along with its approximately 102 islands are protected as a national park by the Iranian Department of Environment. (Photo by Kaveh Kazemi/Getty Images)

Iran’s growing water deficit

To sustain its freshwater resources, a country must replenish at least as much water as it withdraws for agriculture, industry, and household use.

Iran has long been on the wrong side of that equation. Decades of dam construction, intensive farming, and groundwater extraction have pushed consumption far beyond what rainfall can replenish.

In 2025, Iran’s 92 million people consumed around 100 billion cubic metres of water, nearly 13 billion more than its renewable resources could provide.

Agriculture is by far the largest consumer of water in Iran, accounting for about 91 percent of all withdrawals, compared with seven percent for households and two percent for industry. Yet much of that water is lost before it reaches crops, as ageing and inefficient irrigation systems waste a significant share of the country’s most precious resource.

Disappearing dams around Tehran

Iran is one of the world’s major dam-building countries, and has constructed hundreds of large and small dams to store water, generate electricity, and manage shortages.

In recent years, dozens of reservoirs have dropped to extremely low levels, leaving several to nearly run dry.

Before-and-after satellite imagery of Lar Dam, Latyan Dam and Mamloo Dam, all clustered around Tehran and the southern slopes of the Alborz mountains and forming part of the main water supply system for the capital region, reveals how water levels have declined over time as drought and rising demand strain Tehran’s water system.

Drought displacing thousands

Water scarcity is increasingly reshaping where Iranians can live.

As wells run dry and farming becomes harder to sustain, many families are leaving rural communities in search of more secure livelihoods. According to Abdolkarim Hosseinzadeh, Iran’s vice president for Rural Development and Disadvantaged Regions, only 38,000 of the country’s 69,000 villages remain inhabited, while 31,000 villages have been abandoned.

The pressure extends far beyond abandoned settlements. According to Iran’s state-owned Water and Wastewater Company, about 27,000 villages, home to more than 10 million people, are currently experiencing water shortages. In total, more than 70 percent of Iran’s villages are facing some form of water crisis.

Many migrants head towards major cities such as Tehran, Mashhad, Isfahan, and Shiraz. Yet these cities are facing water pressures of their own. Home to more than nine million people, Tehran has seen growing strain on its water system as drought and demand continue to rise.

The map below shows how Iran’s population is concentrated in the western half of the country. Today, roughly 75 percent of Iranians live on less than 40 percent of the country’s land area, concentrating both people and water demand in a relatively small region.

INTERACTIVE-Iran main population centers-1780980355

The effects of water scarcity can also be seen along the Zayandehrud River, once one of central Iran’s most important waterways.

Satellite imagery of Zayandehrud Dam reveals declining water levels upstream after years of drought and overuse.

Further downstream, the consequences become visible in the heart of Isfahan. The historic Allahverdi Khan Bridge (Si-o-Se Pol) was built over a river that sustained the city for centuries.

Today, residents increasingly encounter dry riverbeds beneath its arches as sections of the Zayandehrud repeatedly run dry.

Only a tiny fraction from desalination

Desalination accounts for only about three percent of Iran’s water needs, a stark contrast to Gulf neighbours, which depend on it for the majority of their drinking water.

Most of Iran’s desalination plants are located along its southern coast on the Gulf. As a result, desalination is largely concentrated in coastal cities, while inland areas such as Tehran, Isfahan and most agricultural regions rely on other water sources.

New Large Chinese Submarine With Very Unique Feature Just Caught On Satellite Imagery

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.

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.

FAA grounds New Glenn rocket after botched satellite release

April 20 (UPI) — The Federal Aviation Administration grounded Blue Origin‘s New Glenn rocket after it botched the release of a satellite following its successful launch two hours earlier.

The third launch of New Glenn and second landing of its reusable booster stage “Never Tell Me The Odds” on a drone ship in the Atlantic Ocean was a success in those terms, but the spacecraft delivered AST SpaceMobile’s BlueBird 7 satellite to an orbit too low for it to operate properly.

Blue Origin said Monday that it is leading an investigation into one of New Glenn’s engines producing insufficient thrust to reach the mission’s target orbit.

“While we were pleased with the nominal booster recovery, we clearly didn’t deliver the mission our customer wanted, and our team expects,” Blue Origin CEO Dave Limp said in a post on X.

The FAA, NASA, the National Transportation Safety Board and the U.S. Space Force also have been monitoring the situation and will require Blue Origin to complete its investigation and report on the engine anomaly, the Orlando Sentinel reported.

“A return to flight is based on the FAA determining that any system, process or procedure related to the mishap does not affect public safety,” the FAA said in explaining why it grounded the rocket.

The New Glenn-3 rocket launched around 7:30 a.m. EDT on Sunday morning, nailing the flight and landing portion of its mission, and successfully released the BlueBird 7 satellite once it reached orbit.

Because one of the two BE-3U engines that power New Glenn’s upper stage didn’t produce sufficient thrust on its second engine burn, which is meant to boost the spacecraft to its target orbit above Earth, it never got there.

Although the satellite was released and powered on properly, the off-nominal orbit — which was too low for it to be useful — AST said it would be jettisoned.

BlueBird 7 is one of 45 satellites that AST SpaceMobile hopes to get in orbit by the end of 2026 as part of a satellite-based cellular network designed to operate with standard smartphones.

The satellite would have been the companies eighth to reach orbit, and it’s share price Feller by more than 6% on Monday, The BBC reported.

Limp said Blue Origin is analyzing data as it conducts the investigation and is “in steady communication with the team at AST SpaceMobile.”

“We appreciate their partnership, and we’re looking forward to many flights together,” Limp said.

Angry Kitten Jamming Pod Testing On HC-130J Focuses On Receiving Threat Updates Via Satellite

The U.S. Air Force is continuing to expand on the capabilities of the Angry Kitten electronic warfare pod, which just recently made its combat debut on the F-16 fighter in the latest conflict with Iran.

New testing has focused on improving the ability of HC-130J Combat King II combat search and rescue aircraft carrying the pods to receive reprogramming updates in near-real-time via satellite. HC-130Js just recently flew extremely high-risk and high-profile sorties over Iran as part of the effort to rescue the crew of a downed F-15E Strike Eagle. Being able to rapidly refine and optimize Angry Kitten’s capabilities will help the system remain as effective as possible, even in a very quickly evolving threat environment, and could be a stepping stone to more advanced functionality.

The Air National Guard Air Force Reserve Command Test Center (AATC) recently shared details about new testing of Angry Kitten on the HC-130J during an iteration of the Bamboo Eagle exercise. Bamboo Eagle is a large-scale air combat exercise series focused on preparedness for a high-end fight in the Pacific. AATC has already been test flying Angry Kitten on the HC-130J for more than a year now.

The pods have also been test flown on Air Force A-10 Warthog ground attack jets and Navy F/A-18 Super Hornet fighters. As noted, it is now being employed operationally on Air Force F-16s, as well. Angry Kitten was originally developed to replicate hostile electronic warfare threats during testing and training, as part of a cooperative effort between the Air Force and the Navy, and worked so well that it was adapted to operational use. We will come back to this later on.

During Bamboo Eagle, “AATC’s primary evaluation centered on the Angry Kitten electronic warfare pod integrated aboard a HC-130J Combat King II. The force development evaluation built directly on an operational assessment completed the previous year, which found the system potentially effective and suitable on the platform,” according to a press release that the center put out last week. “Testers incorporated recommendations from that assessment while the 130th Rescue Squadron flew the pod against simulated ship-based and ground-based threats during exercise vulnerability periods, evaluating both survivability and the system’s broader electronic attack capability.”

The 130th Rescue Squadron is part of the California Air National Guard’s 129th Rescue Wing.

“Running alongside that effort, AATC continued maturing the Ka/Ku-band communications suite, which enables over-the-horizon communications and near-real-time electronic warfare reprogramming via satellite link,” the release adds. “The suite compresses what was previously a multi-day technique development and distribution process to near-real-time between sorties.”

AATC has previously disclosed that it has been working on this capability, which looks to be unique to the integration of Angry Kitten on the HC-130J, at least currently. The Combat King II has the benefit of a wide-band satellite communication system, which is also found on U.S. special operations C-130 variants and other aircraft. The HC-130J carries the pod using a Special Airborne Mission Installation and Response (SABIR) system installed in place of its left rear paratrooper door.

“The C-130 testing features innovative real-time updates to electronic warfare techniques,” AATC said in a previous press release in March 2025. “Unlike the F-16 tests, where pre-programmed mission data files were used, the C-130 testing includes development engineers aboard the aircraft who can modify jamming techniques mid-mission based on feedback from range control.”

As can be seen above, to date, AATC has largely framed the benefits of this reprogramming capability within the context of accelerating continuing test and evaluation of Angry Kitten. At that same time, this would also be extremely valuable in an operational context.

In general, electronic warfare systems use built-in threat libraries to accurately detect, categorize, and respond to waveforms. In turn, their effectiveness is inherently determined by the breadth of data in that library. Specialists, often working in purpose-built reprogramming laboratories far from the front lines, have to work tirelessly to keep these systems up to date. Historically, this has been a very lengthy process, and one that has increasingly had trouble keeping pace with the rate at which threats are evolving.

As noted, Angry Kitten was developed first as a training and testing tool. It is a direct outgrowth of the AN/ALQ-167 electronic warfare pod, variants of which have been used in those contexts for decades to mimic hostile electronic warfare threats. However, Angry Kitten was designed from the start to be more readily updatable and modifiable in order to make it easier to adapt it to new and evolving threats.

“At the core of that technology is Angry Kitten’s Technique Description Language architecture. Georgia Tech designed TDL as a hybrid that pairs dedicated hardware modules for speed and bandwidth with software for complex decision-making,” according to a press release Naval Air Systems Command (NAVAIR) put out last month. “The practical result: government programmers can reprogram the jammer to counter new threats without sending it back to the contractor for expensive, time-consuming code changes. When an adversary adapts its radar tactics, NAWCWD’s team can update the jammer’s response in days instead of waiting months for a contract modification.”

Angry Kitten is also known to make use of advanced Digital Radio Frequency Memory (DRFM) technology. Using DRFM, radio frequency (RF) signals can be detected and ‘captured.’ Those same signals can then be manipulated and retransmitted. As an example of what this means in practice, signals from enemy air defense radars or radar seekers on incoming missiles can be recorded and pumped back in a way that creates false or otherwise confusing tracks. That same data can also be used as part of the reprogramming process to improve the stability capabilities, as well as be further exploited for general intelligence-gathering purposes.

This all already contributed to the evolution of Angry Kitten into an operational system.

“We had a jammer called ‘Angry Kitten.’ It was built to be an adversary air jamming tool,” now-retired Air Force Gen. Mark Kelly, then commander of Air Combat Command (ACC), told TWZ and other outlets back in 2022. “And all of a sudden, the blue team said, ‘you know, hey, we kind of need that, can we have that for us?’ And so I see this iterating and testing our way into this.”

When it comes to near-real-time updates for Angry Kitten, even if the communications suite used on the HC-130J won’t fit on smaller tactical jets, it could potentially be ported over into a capability that is readily deployable to forward locations. Another possibility is that an aircraft with a wide-band satellite communications system could then pass updates for Angry Kitten to other aircraft within line of sight using other datalink capabilities.

The underlying developments have further implications when it comes to developing so-called cognitive electronic warfare capabilities. Cognitive electronic warfare is a broad area of development focused on new technologies to further automate or otherwise accelerate the reprogramming process. The absolute ‘holy grail’ of the overall concept is an electronic warfare system that can adapt autonomously in real time to new threat waveforms, or known ones being modulated in unexpected ways, even right in the middle of a mission. You can read more about all of this here.

Ongoing work to expand and improve Angry Kitten’s capabilities will also now benefit from lessons learned from the employment of the pods in combat sorties over and around Iran.

The multi-day effort to recover the crew of an F-15E Strike Eagle downed in that country earlier this month also highlighted the immense risks involved in combat search and rescue (CSAR) operations, and the importance of adding new self-protection capabilities to the HC-130J, specifically. Air Force Combat King IIs can expect to face far greater threats while conducting CSAR missions during a conflict with a near-peer adversary like China. This has prompted questions about the utility of HC-130Js and other traditional CSAR assets in the context of any future high-end fight.

In the meantime, Angry Kitten continues to evolve in significant ways, including its growing ability to receive key updated data remotely in near-real-time when paired with the HC-130J.

Blue Origin launches New Glenn rocket, puts satellite in wrong orbit

April 19 (UPI) — Blue Origin successfully launched its New Glenn rocket and landed its booster stage, but it delivered a communications satellite into an orbit too low to be useful.

New Glenn-3, the third launch of the company’s rocket, cleared the tower just before 7:30 a.m. EDT on Sunday morning and roughly six minutes later its first stage touched down on the “Jacklyn” drone ship in the Atlantic Ocean.

The fully reusable booster, called “Never Tell Me The Odds,” was making its second landing as the mission hit its second stage engine cutoff, entered orbit and released AST SpaceMobile’s BlueBird 7 satellite successfully.

The release was successful and the satellite powered up properly, but had been placed into “an off-nominal orbit,” Blue Origin said in a post on X.

“During the New Glenn 3 mission, BlueBird 7 was placed into a lower than planned orbit by the upper stage of the launch vehicle,” AST said in a press release.

“While the satellite separated from the launch vehicle and powered on, the altitude is too low to sustain operations with its on-board thruster technology and will de-orbited,” the company said. “The cost of the satellite is expected to be recovered under the company’s insurance policy.”

AST’s BlueBird 7 satellite is part of a space-based cellular broadband network the company is building that will be accessible using normal smartphones.

The satellite would have been the eighth the company has put in orbit for the network, has satellites number through 32 in production and expects BlueBird 8, BlueBird 9 and BlueBird 10 to be completed in the next month.

AST said that it plans to continue launching satellites roughly every other month for the rest 2026 using “multiple launch providers,” with a goal of 45 satellites in orbit by the end of the year.

Blue Origin, in addition to launching satellites for commercial and government entities, is also building a prototype MK1 “Endurance” lander as a test vehicle in an uncrewed moon landing later this year, Space.com reported.

The prototype is a test run for its MK2 lunar lander that will be used in NASA’s Artemis program to explore the moon and establish a permanent human presence there.
