underwater

SPOTTING yet another shark, my sister Hayley shouts: “Quick! There are loads over here,” pointing towards the edge of the reef.

We’ve only just jumped into the sea on our 90-minute guided snorkelling trip, £53 each, so I decide to closely follow the guide instead, who points out moray eels, box fish and spotted eagle rays, plus the aforementioned reef sharks, which are thankfully harmless.

There is coral aplenty, and it’s teeming with sea life in every colour of the rainbow, as if I’ve swum straight into a scene from Finding Nemo.

Water View

Staying in a water villa at Oblu Xperience Ailafushi – complete with an outdoor rainfall shower and deck with a ladder straight into the turquoise water below – offers the classic Maldives experience.

The sound of the waves lapping beneath us is more calming than any white noise track I’ve listened to.

Thankfully, this all-inclusive resort on Ailafushi island is not solely aimed at couples, unlike many luxury getaways in the Maldives.

ROCKIN’ AROUND

Moment TORNADO hits Spain as Xmas lights destroyed amid weather red alert

COSTA LITTLE

This is Spain’s cheapest island with £169pp holidays – and it’s still 23C

Even better, it’s just a 15-minute speedboat ride from the capital Malé, which works out much cheaper than a sea-plane transfer.

The main restaurant, Element X, is a buffet eatery, which also helps keep costs down.

Here, we find dishes from all over the world, but it’s the Indian selection with rich, buttery paneer masala, spicy lentil daal and fresh roti, that most hits the spot.

All the action on Ailafushi centres around the main pool, the X360 bar and the neighbouring beach, where water shoes prove handy for the coral.

Daily activities include aqua Zumba, water polo and volleyball, plus a DJ hits the decks at sunset.

There’s even a twice-weekly foam party, which reminds us of teenage trips to Ibiza.

After a few frozen piña coladas, the nightly karaoke proves entertaining, and there’s a games room complete with pool tables, board games and huge screens playing live sport.

But it’s the water slide that drops you straight into the Indian ocean that becomes our favourite activity.

Beach Happy

At the other side of the island – a 10-minute stroll away – we find the Elena Spa And Wellness Centre, one of the Maldives’ largest spas, with landscaped tropical gardens that blend indoors with outdoors.

My treatment room overlooks the beach, and beneath the spa soundtrack I can hear the gentle sound of the waves.

The Balinese massage, £57 for 60 minutes, melts away tension from our long flight, while Hayley’s detoxifying lymph massage leaves her abs looking super-sculpted.

As well as treatments, there’s a steam room, sauna and salt water infinity pool, £8 for an hour, plus a juice bike which you can pedal to blend your fruits of choice.

Later, on the 90-minute dolphin cruise, which costs £53 each, we camp out on the bow of the boat, and are soon fortunate enough to spy a pod complete with a calf leaping out of the water just as the sunset turns the sky orange.

We celebrate with a delicious five-course lobster-themed beach dinner from The Copper Pot food truck, £60 each, that includes brown butter lobster tortellini, poached lobster, fennel and mango salad and a gigantic lobster thermidor.

Another ray in paradise

Our most memorable evening is spent at Oblu’s underwater restaurant Only Blu.

At 6.8m below sea level, we tuck into three courses with wine pairings, and marvel at the marine life on the other side of the super-sized windows.

As we’re feasting on scallops with pickles and cauliflower, and Maldivian yellowfin tuna poke, a 5ft-long nurse shark glides past and hundreds of tiny fish quickly dart into the reef to camouflage themselves among the coral.

It’s not long before we spy a similar-sized blacktip reef shark, and I lose count of the number of rays that appear alongside brightly coloured trigger and lion fish, before my main course of melt-in-the-mouth, pan-fried reef fish with corn mash and an olive and caper emulsion arrives.

A gulab jamun cheesecake and rich deconstructed banoffee pie don’t disappoint either, and the night proves well worth the extra £95 each.

With the fish still entertaining us just a few feet away, if we could, we’d both happily stay here until sunrise.

ISLE BE BACK

Meanwhile, writer Samantha Rea found joy on the island of Sark.

The “toast rack” – which is basically a row of benches on a trailer pulled by a tractor – is chugging me uphill from the harbour.

With no seat belts or doors, I hold on for dear life.

But seeing as only tractors and horse-drawn carriages are allowed on the tiny isle of Sark (yes, there are no cars!), this is the best way to reach The Avenue, Sark’s main street.

And at £1.80 a ride, it’s worth a go.

Sitting in the English Channel, just off the French coast, Sark is 3.5 miles long and 1.5 miles wide with some fab foodie gems.

At Caragh Chocolates, I decorate truffles and a huge slab with hazelnuts, fudge and cranberries alongside owner Caragh, before leaving with my delicious creations.

Ninety-minute workshops cost £45 (Caraghchocolates.com).

While at cosy Nova’s Bistro, portions are generous and the rich beef stew with pastry lid, £26, and treacle tart, £9.50 (@Novas. bistro) are well worth the 20-minute walk from Stocks Hotel, where I’m kipping

I walk off some of my indulgence the next day on a one-hour tour of La Seigneurie House and Gardens, with its gorgeous fountains, bridges and chapel. It’s owned by a family who are like Sark’s royals and has a fascinating history. Entry costs £8 (Laseigneurie desercq.uk).

Sark is also great for wild swimming – the best spots being Dixcart Bay, Les Fontaine Bay and La Grande Greve.

Meanwhile, if you want to see the Milky Way once night falls, head to Sark Observatory, £10 (Darkskyisland. co.uk).

And just like the song, you’ll hopefully soon be counting stars. . .

UK flights to Guernsey cost from £100 return. Ferries to Sark cost from £38.50 return (Sarkshipping.gg).

Double rooms at Stocks Hotel cost from £250 B&B (Stockshotel.com).

Satellite imagery is now available showing the aftermath of a Ukrainian attack yesterday on a Russian Navy Improved Kilo class diesel-electric submarine in the Black Sea naval stronghold of Novorossiysk. The Security Service of Ukraine (SBU) claimed that this was the first attack against a Russian vessel using an uncrewed underwater vehicle (UUV). The operation could also mark the historic first successful use of a UUV as an anti-ship weapon, but the actual level of damage inflicted on the submarine remains unclear. Readers can first get up to date on the attack in our initial reporting here.

TWZ obtained satellite images of where the attack occurred in Novorossiysk from Vantor (formerly Maxar Technologies). Additional imagery from Planet Labs has also been circulating online.

The satellite imagery confirms that the UUV — named by the SBU as a Sub Sea Baby, a previously unknown type — detonated off the stern of the submarine, which was at a pier in the port of Novorossiysk. A substantial chunk of the pier itself was destroyed in the attack. This all aligns with video footage shot during the attack from a position on the ground nearby, which the SBU released yesterday.

The post-strike imagery shows that the Improved Kilo class submarine, also known as a Project 636.3 Varshavyanka class type, is in the same position as it was before the attack. Two other submarines that were moored nearby when the attack occured have moved. Other submarines and ships are still in the moorings, including on the outside edge of the damaged pier.

Some of the imagery available now suggests that the submarine that was attacked may now be sitting lower in the water, but that can’t be readily confirmed. Any damage below the waterline would also not be visible in the images. At the same time, there are also no clear signs of any emergency measures having been taken to keep it afloat, or to contain the leakage of oil or other potentially hazardous fluids, as one might expect to see if the damage was severe.

Based on the estimated length of what is visible of the submarine, some observers have noted that the epicenter of the explosion looks to have been less than 65 feet from the stern. The size and configuration of the Sub Sea Baby’s warhead, as well as other details about the UUV and its capabilities, remain scant.

To note, the stern section of Kilo-class submarine remains submerged so presumably it was even closer than 20 meters.

Highly probable that at least the propelled end got affected in a kinetic way.

It’s also worth noting that wider views of the port of Novorossiysk following the attack show four Project 636 submarines still present. There is nothing definitive to indicate that the targeted boat might have been replaced by another to conceal the extent of the damage.

For its part, the Russian Ministry of Defense had unsurprisingly denied that any damage was inflicted on the submarine or to any personnel at the port. The ministry has released a video that it claims shows the undamaged boat, but does not offer a view of the stern end. The background is also heavily censored. Even so, it does still reveal what looks like piles of broken concrete debris left on the pier after the explosion, which was clearly visible in the SBU’s video of the attack, as well as in the satellite imagery available now.

The press service of the Russian Black Sea Fleet, which operates the submarine, also denies any damage to its vessels. This is also consistent with reports from various Russian naval monitoring channels on social media, but clear corroborating evidence has yet to emerge.

Overall, at this stage, we still cannot say with any authority what degree of damage, if any, the submarine may have actually sustained.

On the other hand, the attack does show Ukraine was at least able to slip a UUV into a heavily defended harbor, in daylight, and detonate its warhead only a few dozen or so feet away from a prized Russian submarine worth, according to the SBU, around $400 million.

At least one Ukrainian UUV was therefore notably able to penetrate past barriers erected at the mouth of the port, intended specifically to protect the vessels within. It’s worth noting, however, that the defensive barriers Russia has already built around ports were primarily put there in response to Ukraine’s uncrewed surface vessel (USV) campaign. This underscores the significance of the use of a UUV in this attack, as another example of the steady adaptation of weapons systems and tactics in response to countermeasures that has become a particular hallmark of the conflict in Ukraine.

With that in mind, Russia is likely to introduce new countermeasures against this particular mode of attack, one which Ukraine has spent some time developing.

The results of yesterday’s attack, while inconclusive for now, will likely spur further such developments in Ukraine, as well. Before SBU targeted the submarine in Novorossiysk, Ukraine had unveiled a UUV dubbed Marichka, designed to launch kamikaze attacks against ships and maritime infrastructure. At least one other Ukrainian UUV, known as Toloka, has previously been disclosed. It’s unclear if either of these has any relationship to the Sub Sea Baby.

Video of the Toloka UUV:

Furthermore, the attack confirms that the Black Sea Fleet is very much still a prime target for Ukraine. This applies especially to the submarines like the Project 636 types and corvettes that are able to launch Kalibr long-range cruise missiles. These weapons have been regularly used in Russia’s nightly barrages launched against targets across Ukraine.

Already, Ukrainian naval actions had forced the Black Sea Fleet to retreat from bases on the occupied Crimean Peninsula to Novorossiysk. Attacks in Crimea were also prosecuted against another Improved Kilo class submarine. In September 2023, the Rostov-on-Don was severely damaged during a combined missile and USV attack on Sevastopol. Ukraine later claimed it was destroyed.

At the start of Russia’s full-scale invasion of Ukraine, the Black Sea Fleet had a total of six Project 636 submarines available.

Other navies around the world will likely have watched yesterday’s attack with interest.

As well as the United States, China and many other nations are developing their own UUVs for missions like this one.

UUVs are able to attack vessels and other targets at long distances and can be launched from submarines and motherships, further extending their range. They can also be used for surveillance and mine laying, among other duties. You can read more about these vessels in various TWZ stories here.

Ultimately, whether or not the Russian submarine was damaged, the attack has demonstrated once again that the war in Ukraine is a crucible for the development of new military technologies, especially uncrewed ones.

Ukraine’s state security service (SBU) said it carried out the first-ever uncrewed underwater vehicle (UUV) attack on a Russian vessel. The strike was on a Project 636 Varshavyanka class, or Improved Kilo class diesel-electric submarine, in the Black Sea naval stronghold of Novorossiysk. It would mark a historic first successful use of a UUV as an anti-ship attack weapon.

The SBU released a video it says shows the submarine docked at Novorossiysk along with several other ships. The video pans from right to left and at about the 16-second mark, the submarine erupts in an explosion. That means the UUV, which is not visible in the video, was able to navigate a packed harbor to strike a specific vessel. While we cannot independently verify the SBU claim about the use of a UUV in the strike, they did confirm that assertion to us directly.

Russia, meanwhile, denies any damage was caused by the attack.

‘The information disseminated by special services of Ukraine about the alleged ‘destruction’ of one of the Russian submarines in the bay of the Black Sea Fleet’s Novorossiysk naval base does not correspond to reality,” the Russian Defense Ministry (MoD) claimed on Telegram. “Not a single ship or submarine as well as the crews of the Black Sea Fleet stationed in the bay of the Novorossiysk naval base were damaged as a result of the sabotage. The watercraft serve normally.”

Today’s UUV attack appears to be the culmination of Ukraine’s development of these weapons and once again shows that the war-torn country is at the forefront of modern drone warfare innovation. Little is known about the Sub Sea Baby UUV, not to be confused with the highly adaptable Sea Baby uncrewed surface vessels (USVs) that have wreaked havoc on the Russian Navy.

Ukraine is developing several UUVs, at least that we know of. It released images in September 2023 of a UUV dubbed Marichka, designed to launch kamikaze attacks against ships and maritime infrastructure. That followed the announcement earlier that year of another UUV known as Toloka, which you can see in the following video.

Автономний підводний дрон TOLOKA

Being able to operate underwater not only helps greatly in avoiding detection and destruction, but it can also potentially mitigate some defensive barriers Russia has already built around ports as a result of Ukraine’s uncrewed surface vessel (USV) campaign. This onslaught has already kept Russia’s Black Sea Fleet (BSF) at bay, forcing it to retreat from Crimea to Novorossiysk. Ukrainian USVs have also damaged enemy military facilities in occupied Crimea and the Kerch Bridge, You can see one Ukrainian USV being destroyed below.

The U.S., China and many other nations are developing their own UUVs for missions like the one that struck the Improved Kilo class submarines. UUVs can provide the ability to strike vessels and other targets at long distances and can be launched from submarines and motherships, extending their range. They can also be used for reconnaissance and mine laying, among other duties. You can read more about these vessels in our catalogue of stories here.

In the case of the Improved Kilo class boat, “the vessel suffered critical damage and was effectively put out of action,” the SBU claimed. “On board the submarine were four launchers for ‘Kalibr’ cruise missiles, which the enemy uses to strike at the territory of Ukraine.”

The submarine damaged by the Sea Baby UUVs is one of six Improved Kilo class boats that were operated by the Russian Black Sea Fleet, a retired Russian Navy officer who uses the @Capt_Navy X handle told The War Zone.

These submarines are quite capable and can be very hard to detect when dived and running on battery power. These submarines carry Kalibr long-range cruise missiles that have frequently been used to attack Ukraine.

The Sub Sea Baby UUV attack “was a joint operation of the 13th Main Directorate of Military Counterintelligence of the SBU and the Naval Forces of Ukraine,” SBU explained, adding that the estimated cost of one of the Russian submarines is about $400 million.

This incident also marks the second time an Improved Kilo class submarine in Crimea was attacked by Ukraine. In September 2023, the Rostov-on-Don was severely damaged during a combined missile and uncrewed surface vessel (USV) attack on Sevastopol. Ukraine later claimed it was destroyed. You can see the damage to that submarine below.

If today’s attack did damage the submarine significantly, Russia would be left with four examples operating as part of the Black Sea Fleet.

While much about the Sub Sea Baby UUVs remains a mystery, a proven ability to use them as weapons holds Russian vessels at even greater risk. Novorossiysk was seen as something as a relative safe haven for the Black Sea Fleet, although aerial and sea drone attacks have occurred there. But the idea that Ukraine can use underwater drones to strike ships in port there changes this calculus, if that is indeed the true method of the attack. As a result, we will also be seeing a change in Russia’s defensive posture at the sprawling port located on the northeastern edge of the Black Sea.

At the same time, if this attack was executed by a UUV, it would be another world first and is likely a harbinger of things to come. Hitting ships in port over great distances via underwater drone attack is an asymmetric capability. It’s also one that America’s adversaries are investing in heavily, and especially China.

With all this in mind, the attack on the submarine serves as another reminder that the war in Ukraine has become a conflict where theory and development are put into practice.
