With no traditional navy of its own, Ukraine has relied on 3 military innovations to hammer Russia's Black Sea Fleet

The Magura V5 is a multi-use uncrewed surface vessel.

The homegrown Ukrainian drone is around five-and-a-half meters long (about 18 feet) and can carry a payload of 320 kg (roughly 705 pounds), according to the naval analyst H I Sutton.

The V5 can hit a top speed of roughly 42 knots (around 48 mph) and has a range of about 450 nautical miles, Sutton says on his website.

The drone has reportedly been involved in a number of key incidents during the war.

Ukrainian intelligence has said that Magura V5 drones were used to attack the Russian corvette Ivanovets, the Sergei Kotov patrol ship, and the Caesar Kunikov landing craft.

An unspecified number of Magura V5 naval drones have also been modified to carry R-73 short-range air-to-air missiles, the Defense Intelligence of Ukraine has said.

This version of the drone was first spotted in May and has already been used during combat operations in the Black Sea, the service said last month.

The R-360 Neptune is a subsonic cruise missile developed in the Ukrainian capital Kyiv.

The missile has a range of around 200 miles and weighs about 2,000 pounds.

Ukraine has used these anti-ship missiles to strike high-value targets and as an alternative to the ATACMS — as the Biden administration has limited where Ukraine can use the US-made system.

The Neptune missile was used in the sinking of the Black Sea Fleet's flagship, the Moskva, and a modified version of the missile may also have been used to hit Russian air defenses, including S-400s stationed in Crimea.

Ukraine has attempted to alter the Neptune missile so that it can attack such land targets.

According to the Institute for the Study of War, "Ukraine first debuted Neptune anti-ship missiles against Russian naval targets in April 2022."

The think tank noted that Ukraine had "had to further develop and modify" the Neptune missiles as the war has gone on in order "to conduct deep strikes against Russian territory."

The domestically produced Sea Baby is another of Ukraine's unmanned surface vehicles.

The drone is slightly longer than the Magura V5, coming in at six meters long (almost 20 feet), and it can hit a top speed of 49 knots (around 56 mph), according to Sutton.

It can travel up to 540 nautical miles and can carry a payload of 850 kg (around 1,870 pounds), Sutton says.

Earlier this month, Artem Dehtiarenko, a spokesperson for the Security Service of Ukraine, said the Sea Baby had undergone a significant upgrade, Ukrainian media reported.

"If we're talking specifically of upgrading Sea Baby drones, which hit the Crimea bridge last year, as of today they have completely different characteristics, having become much more powerful," he said.

"For example, a year ago our drone could carry about 800 kg of explosives to a distance of about 800 km, and today it is over 1,000 kg and over 1,000 km. So today the SBU can attack enemy ships virtually anywhere across the Black Sea," he added.

Ukraine has said Sea Baby drones have been involved in a number of major strikes on Russian ships, including the patrol ship Pavel Derzhavin in October and the Olenegorsky Gornyak in August.

A Sea Baby was also credited with damaging Russian President Vladimir Putin's prized Kerch Bridge, which links Crimea with the Russian mainland, last year.

Despite Ukraine's successes, one expert previously told Business Insider that Russia still had some advantages in the naval arena.

Sebastian Bruns, a senior researcher at the Center for Maritime Strategy and Security at Kiel University, said that while Ukraine's operations in the Black Sea region have proven to be "powerful enough to sink or disable more than half of the high-value units of the Russian Black Sea fleet," Russia "still has the upper hand holding ports and shipping lanes at risk through targeted missile strikes and sewing mines."

"Ukraine won't win the war in the maritime domain only, but it could surely lose it there," he added.
