NewsTranscript
00:00Ukraine's unmanned arsenal has evolved enormously over the last couple of years.
00:04We've seen Kyiv's defense sector produce a dizzying array of innovations,
00:08from jet-powered bomber drones to AI-powered kamikaze killbots.
00:12But the latest addition may be the biggest and most impressive yet.
00:16Introducing the Sea Trident, a 10-ton beast of the seas,
00:20packing enough firepower to threaten the very existence of the Kremlin's Black Sea fleet.
00:24It's no exaggeration to say that this new drone could prove to be a game-changing asset.
00:30Opening whole new avenues of both offensive and defensive operations to Ukraine's armed forces,
00:35while giving Russia a truly massive new threat to worry about.
00:39The Sea Trident was shown off for the first time at the Eurosatarii 2026 event in Paris.
00:44Held every two years, Eurosatarii is the largest international exhibition
00:48for the land and air land defense and security industry.
00:52It attracts tens of thousands of guests with thousands of exhibitors from dozens of countries
00:57showing off their latest military innovations,
00:59from vehicles like tanks and trucks to small arms, communication systems and so on.
01:05Recent iterations of this event have seen a growing presence from the Ukrainian defense sector,
01:09which has quickly become one of the biggest and best in the world.
01:12And at the 2026 exhibition, Kyiv-based defense firm Global Mark was in attendance
01:18to wow the world with its enormous underwater unmanned vehicle,
01:21measuring up at a whopping 10 meters, 32.8 feet in length,
01:26with a width of 2 meters, 6.5 feet, and a height of 1.5 meters, 4.9 feet,
01:32this is no ordinary drone.
01:33It's more like a supersized torpedo, at least in terms of its aesthetics.
01:38Tipping the scales at a colossal 10,000 kilograms, 22,000 pounds,
01:43it easily ranks amongst the heaviest drones in the Ukrainian arsenal,
01:46and is capable of carrying a similarly huge payload of up to 1,000 kilograms or 2,200 pounds.
01:53Global Mark representatives also reveal that this drone has an operational range of up to 2,000 nautical miles
01:59and a maximum operational depth of 60 meters, approximately 200 feet.
02:04It can travel at a maximum speed of 10 knots or 18.5 kilometers per hour or 11.5 miles
02:10per hour,
02:11with a cruise speed closer to 6 knots, around 11 kilometers per hour or 7 miles per hour.
02:17The developer also revealed that the Sea Trident has been designed with a wide array of mission types in mind.
02:22Even though it may seem like a purely offensive asset at first glance,
02:26Global Mark claims it could be used for the likes of logistics and transport tasks,
02:30such as cargo deliveries, as well as strike missions and defensive operations,
02:35such as intercepting and neutralizing opposing underwater unmanned vehicles, for example.
02:40It's worth noting, too, that the company hasn't yet revealed how far along the platform's development is,
02:46or how soon it could be rolled out to service in the Ukrainian armed forces.
02:50However, the very fact that Global Mark was willing to show off this drone at the Euro Saturday event,
02:55suggests that it's likely quite deep into the development process.
02:58And the Sea Trident already has Russia running scared.
03:01One of the country's military experts, Vladimir Yeran-Osyan,
03:05an associate professor at the Financial University under the government of the Russian Federation in Moscow,
03:10shared his thoughts about the Sea Trident in an interview with one of the country's biggest weekly newspapers, AIF.
03:17Initially, Yeran-Osyan attempted to play down the innovation,
03:20claiming that the Sea Trident wasn't actually a true Ukrainian innovation,
03:24but was instead likely to be made up of different parts produced in Western countries,
03:28like the United Kingdom, Germany, and the United States.
03:31He also suggested that Global Mark might have been lying or exaggerating about the drone's technical specifications and capabilities,
03:39before admitting that it could be used to strike numerous pieces of port and coastal infrastructure,
03:44for example, sea terminals, or loading stations of oil and gas products, bridges, dams, and possibly hydroelectric power plants.
03:52The expert then added,
03:53Surely the enemy will try, with the help of Sea Trident, to sink large warships or submarines of the Russian
03:59fleet.
03:59He went on to spout the usual Kremlin-style propaganda,
04:03claiming that there's no real reason to worry,
04:05as Russia has faced numerous Ukrainian and Western drones in the past and adapted to them.
04:10He outlined a list of potential defenses the Kremlin could set up to counter this threat,
04:15like port entrance barriers,
04:17special listening posts to scan for the sounds of incoming threats beneath the surface,
04:21and even military divers patrolling key coastal locations.
04:25In reality, however, none of these measures would necessarily be enough to counteract the massive threat that the Sea Trident
04:31poses.
04:32Its advanced navigation systems could allow it to easily evade or circumvent Russian barriers,
04:37adjusting its depth and trajectory to strike its targets with impunity.
04:41Additionally, while Yeranosyan claims that the Kremlin's forces have successfully dealt with Ukraine's drones in the past,
04:48there is an enormous amount of evidence to disprove that.
04:50Indeed, the war has now reached a point where barely a single day passes,
04:55without fresh reports of yet another Ukrainian drone strike on Russian assets and infrastructure.
05:00Kiev's forces have been systematically eradicating Russian targets one by one,
05:05damaging and destroying everything from naval vessels to oil terminals and ammo depots,
05:10and the Kremlin's army has repeatedly failed to stop them.
05:13Its radars have been too sluggish, its air defences have been insufficient,
05:18and its forces have been caught off guard over and over again.
05:22This is equally true on land as it is at sea,
05:25as we've seen Ukraine's forces make strong use of their air and water-based drones,
05:29as well as missiles, to carry out numerous successful strikes on Russian ships in the Black Sea and beyond.
05:36In fact, these attacks began way back in 2022, during the opening exchanges of the war.
05:41Mere weeks into the conflict, for example, in March 2022,
05:46Ukraine used a Tochka-U ballistic missile to sink a large Russian landing ship in the occupied port of Berdyansk.
05:53Only a month later, Ukraine's forces celebrated one of their most iconic victories
05:57when they used their own Neptune anti-ship missiles to eliminate the Black Sea Fleet's flagship vessel,
06:02the Moskva missile cruiser.
06:04In the months that followed, we saw the likes of landing craft, assault boats, and support vessels
06:09either damaged or entirely destroyed,
06:11and as Ukraine's forces grew even stronger over the years,
06:15more and more of the enemy's vessels were eliminated.
06:17Even Russia's submarines weren't immune to these strikes.
06:20In September 2023, for example,
06:23Ukrainian missiles penetrated the hull of the Rostov-on-Don,
06:26and in December 2025, Ukraine used both aerial and surface drones
06:31to strike a Russian Project 636 submarine.
06:34Kiev's forces have also destroyed the rail ferries that helped Russia funnel supplies to Crimea,
06:40slowly starving the occupied peninsula of ammo and other military equipment,
06:44and every single year of the conflict has seen numerous ships of various sizes and classes
06:48sink to the briny depths or have to be towed away for costly repairs.
06:52These attacks have proven so effective and impactful that they've almost entirely nullified the Black Sea Fleet.
06:58As the Kremlin's commanders saw that more and more of their ships were being damaged
07:02and didn't have the necessary defenses to deal with Ukraine's UAVs and missiles,
07:06they began to move them further and further back from the conflict zone.
07:09As time went by, there were fewer Russian ships sailing across the Black Sea,
07:13with most of them simply sitting in ports or shipyards,
07:16hiding out and hoping that Ukraine would leave them alone.
07:19This, in turn, meant that there were fewer vessels actively launching the likes of
07:23caliber-class missiles at Ukrainian towns and cities.
07:26In other words, by counteracting the Black Sea Fleet,
07:30Ukraine was able to decrease the power of Russia's bombardments
07:33and save countless lives in the process.
07:35In short, it transformed the Black Sea Fleet from an active and potent threat
07:39into a veritable liability for Russia.
07:42Rather than using its naval vessels to strike its opposition
07:45and extend its advantage on the ground,
07:48the Kremlin is now unable to extract almost any value from these assets
07:51and instead has to spend most of its time, money and resources
07:54either protecting them or repairing them.
07:57And the most incredible part of all of this
07:59is that Ukraine pulled this off without a conventional navy.
08:02It relied mostly on drones and missiles
08:05to defeat what was supposed to be one of the strongest naval forces on Earth.
08:08And the Sea Trident has the potential
08:10to take its naval operations to an exciting new level.
08:13Now, before we get into how this new underwater drone might be used
08:17and the unique advantages it brings,
08:20there's more where this came from.
08:21So if you're getting value from the military show,
08:23don't forget to subscribe.
08:25Ukraine has used water-based drones before.
08:28There's the Maritime Autonomous Guard Unmanned Robotic Apparatus,
08:32or Magura V-5, for example,
08:34developed for the use by the Main Directorate of Intelligence of Ukraine,
08:38GUR,
08:39and capable of carrying out a range of tasks,
08:41including surveillance, reconnaissance, maritime patrols,
08:45mine countermeasures, search and rescue, and combat missions.
08:48These drones entered service in 2023,
08:51with subsequent years witnessing the arrival of the V-6 and V-7 models.
08:55Costing around $273,000 per unit,
08:59the Magura V-5 has proven incredibly effective on the battlefield,
09:03directly contributing to the destruction of numerous Russian vessels,
09:06including a Kula-class landing craft,
09:09Tarantul-class missile corvettes,
09:11and patrol ships.
09:12But the Magura has its limits.
09:14The V-5 has a maximum payload capacity of around 300 kilograms,
09:18or 660 pounds, for example,
09:20and an operational range of around 800 kilometers, or 500 miles.
09:24Even the more advanced V-7 version can only carry a 650-kilogram,
09:29or 1,433-pound forehead,
09:32at distances of up to 1,000 kilometers, or 620 miles.
09:37The C-Trident is better in almost every aspect.
09:40It's bigger, bulkier,
09:42and capable of carrying significantly more firepower over far greater distances.
09:46The fact that it can carry up to 1,000 kilograms,
09:48or 2,200 pounds of explosives,
09:51puts it in a completely different class from most other drones Ukraine currently uses.
09:56While smaller drones may only be able to deal superficial damage to Russian vessels,
10:01the C-Trident packs more than enough firepower to take out even the biggest targets.
10:05Plus, since this heavy drone operates under the water's surface,
10:09it should be able to strike the likes of submarines and cruisers in their weakest locations,
10:13blowing holes in their hulls that could quickly cause them to flood and sink
10:17before their crews can carry out emergency repairs.
10:20The C-Trident's vast range is another distinct advantage that elevates this asset
10:25above most other drones Ukraine has used up to this point.
10:28Since it can travel up to 2,000 nautical miles,
10:31the equivalent distance of traveling from Odessa on the southern coast of Ukraine
10:35to the coastlines of Spain or Algeria,
10:38the C-Trident would have no trouble traversing the entirety of the Black Sea.
10:41In fact, it has enough range to travel from Ukraine to Russian port cities,
10:46like Novorossiysk or even the occupied Crimean port of Sebastopol,
10:50before heading back to Ukraine without any risk of running out of fuel.
10:54That opens up countless opportunities for Ukraine's armed forces
10:58to plan and execute their operations in the foreseeable future.
11:01With a weapon like this in their arsenal,
11:03they'd find it easier than ever to orchestrate devastating strikes on Russia's naval assets,
11:08and the Kremlin would effectively have no way to protect its ships.
11:11Even if it relocated some of them through the Kerch Strait
11:14and into the Sea of Azov towards other port cities,
11:17the C-Trident would still be able to find and destroy them.
11:20The fact that the C-Trident travels below the surface
11:23also makes it a very different proposition for Russia to deal with
11:26compared to a surface-level drone like the Magura V-5.
11:30While surface drones are designed to be difficult to detect,
11:33they can still be spotted by planes or drones overhead.
11:36However, by traveling up to 60 meters underwater,
11:40the C-Trident will be impossible to spot from above.
11:43Russia will have to rely on the likes of underwater dive teams
11:45and advanced radar or sonar systems to have any chance of spotting these drones.
11:50This too should help Ukraine when it comes to carrying out surprise strikes
11:54on enemy vessels from below.
11:56And the very fact that a drone like this exists
11:58will strike fear into the hearts of Russian sailors and navy personnel
12:01because even if the waters seemed clear,
12:04they'll know that a 2,200-pound warhead could still be heading their way,
12:08hidden beneath the waves.
12:10The Russian Black Sea Fleet has already been running scared for several years,
12:13and the Sea Trident gives it a whole new nightmare to fear.
12:17This may make the Kremlin's naval commanders even more reluctant to use their ships,
12:21preferring instead to keep them close to the coast or docked in port,
12:24rather than sending them out to sea to fire missiles and launch drones at Ukrainian targets.
12:29And the benefits don't stop there.
12:31During the Eurosatari exhibition,
12:33Globalmark also announced that the Sea Trident is equipped with autonomous control systems
12:38and adaptive navigation.
12:39That means it can carry out its long-range missions with minimal operator involvement.
12:44In other words, this beast doesn't even need a pilot.
12:47Most of the time, it can rely on its own built-in AI systems to help get it where it
12:52needs to go,
12:53adjusting its course while en route to its destination,
12:55in order to give it the best chances of achieving any objective it's given.
12:59And as stated by the developer itself,
13:02this drone can be assigned a surprisingly broad range of objectives.
13:06Its most obvious use would be to carry its payload all the way to an enemy vessel
13:10and ram it from below,
13:12triggering a devastating explosion that would quickly sink most ships.
13:15However, it doesn't necessarily need to carry any explosives at all.
13:20Globalmark notes that it could be used for transporting supplies across bodies of water,
13:24which could prove useful in the future
13:26if Ukraine's forces were attempting to fully liberate Crimea, for example,
13:30or if they needed to move ammunition and other resources
13:33from one coastal location or port to another,
13:36with minimal chance of them being intercepted on the way.
13:39The operational opportunities simply go on and on,
13:42with the manufacturer also noting
13:44that Sea Trident drones could be used to patrol friendly waters
13:47and intercept enemy drones as well.
13:49In short, this is a remarkably versatile addition to the Ukrainian drone army.
13:54Of course, like any other drone, it's not perfect.
13:57It has its limitations that Ukraine's unmanned system forces will have to adapt to
14:01if they decide to introduce this weapon into the war with Russia.
14:05For example, it's not the fastest drone around.
14:08The Magura V5 can reach peak speeds of around 42 knots,
14:11approximately 78 kilometers per hour, or 48 miles per hour,
14:16and cruises at around 22 knots, 41 kilometers per hour, or 25 miles per hour,
14:21while the Sea Trident moves significantly slower.
14:24This could potentially put it at risk of being intercepted more easily,
14:27if Russia can find out how to spot it.
14:30However, it's clearly been crafted with the element of surprise in mind,
14:33and the fact that it moves so slowly
14:35may make it less likely to appear as a threat on Russia radar screens.
14:39It may look more like a large fish or a floating piece of debris
14:42than an imminent explosive risk, for example.
14:45Additionally, even though the Sea Trident can operate below the surface,
14:49it can't go too deep.
14:50Its 200-foot maximum dive distance would make it unsuitable for use
14:54in the likes of deep-sea or ocean-based strikes,
14:57meaning that it will mainly be used in shallow water and coastal locations.
15:01As far as Ukraine is concerned, however, that doesn't really matter.
15:05Ukraine's forces don't need to worry too much about attacking Russian ships at sea.
15:09Since so many of them spend most of their time sitting in shallow water docks and ports,
15:13the exact locations that the Sea Trident was created for.
15:17This gives Russian commanders a veritable Catch-22 dilemma.
15:20If they move their ships out of port and into the open sea,
15:24they become much more vulnerable to aerial drone or missile strikes,
15:27which could sink them before they're able to make it back to base.
15:30If, however, they leave their vessels in port,
15:33the lethal Sea Trident drones can pick them off with ease.
15:35On top of that, this new heavy drone could also be used in attacks against key pieces of infrastructure,
15:41like the support beams of the Crimean Bridge, for example,
15:44or ports where oil and other resources are loaded onto Russian Shadow Fleet tankers.
15:49Overall, it's yet another valuable addition for Ukraine.
15:53It's also a testament to the ingenuity of the country's defense industry,
15:57which continues to go from strength to strength.
15:59While Russia is struggling to cope with countless problems,
16:03from its failing economy to its stalling frontline forces and catastrophic losses,
16:07Ukraine is quietly but confidently going about its business,
16:10both at the front and far behind.
16:12Its soldiers and drone operators continue to deal devastating losses to their enemy,
16:17while its defense contractors continue to innovate and excel,
16:20producing an ever-expanding array of weapons, vehicles, and unmanned systems,
16:24with the potential to help Ukraine become even stronger than ever before.
16:28Ukraine also continues to benefit from the generous support of its NATO allies.
16:33You can learn more about that in this video,
16:35which looks at how the alliance is building up to its biggest ever financial commitment to Ukraine.
16:40Alternatively, check out this video for a look at how Russia thought it had outsmarted Ukraine,
16:45only to be proven utterly and embarrassingly wrong all over again.
