Sea Baby hit a tanker of Russian "shadow float" at the entrance to New Russian

3 May Ukrainian marine unmanned systems Sea Baby hit two tankers of the Russian "shadow float" at the entrance to the port of Novorosyjsk. President Volodymyr Zelenski published a thermal camera recording and reported that the ships used to transport oil could no longer carry out this task.

Cheap tool, expensive effect

Two tankers of Russian "shadow float" were attacked at the entrance to Novorossian. No information was given about the oil spill or the casualties among the crew. However, not only the scale of the damage, but the fact that the pressure on the ships used to transport Russian oil is transferred, is important.

Sea Baby, a naval drone developed by the Security Service of Ukraine, costs around $221,000. In the reality of the naval war, it is a small amount, especially when on the other side is the oil transport system counted in billions of dollars.

That's the point. Ukraine does not need to sink the whole "shadow float". All she has to do is question its predictability, security and economic account.

Shadow fleet under Ukrainian pressure

According to the Russian data, ‘Shadow fleet" has approximately 1337 units and is responsible for nearly 72 percent of Russian oil tankers carrying outside the western insurance and financing system. In March, Russian oil exports by sea reached 7.1 million barrels a day, bringing around $19 billion in revenue.

This is not the margin of the Russian war economy. It's one of her bloodstream. Therefore, the impact in the tanker at Noworosiansk is not just an episode with the use of new weapons. It is a signal that Ukraine is increasingly moving pressure to the sea.

Over the years, sanctions were to cut Russia off from oil money. In practice, the price limit mechanism proved to be leaky, flag changes on ships accelerated, and some Russian raw material found customers by other channels. Where diplomacy was embedded in compromises, Ukraine reached for a simpler and much more direct tool.

Sea Baby, an industrial response to war

Sea Baby has a basic operational range of 1000 km. After the modernization of October 2025, the range was increased to over 1500 km and the payload increased from 850 to 2000 kg. The maximum speed is 90 km/h.

The platform has a composite low detection hull, two waterjet propulsors powered by 400 hp engines and a modular cargo space. Depending on configuration, it can carry explosives, rocket launchers or machine guns with automatic guidance. According to the information provided, the structure is secured for reuse and can be offered to partners.

Zelenski said in April that Ukraine could provide allies with around 2,000 unmanned marine systems of various variants if such a demand arose. This is no longer a technical curiosity. It's a production announcement that changes the power system at sea faster than classic Shipbuilding programmes.

From paper sanctions to industrial sanctions

The Ukrainian strike campaign in Russian oil infrastructure was to cost Russia at least $7 billion between January and May 2026. In November 2025 Sea Baby drones damaged tankers Kairos and Virat off the coast of Turkey. On April 29, 2026, a unit was struck MARQUISE in the Tuapse area.

Noworosyjsk is another point on this map. According to the Russian data which Zelenski referred to, port capacity was to fall by about 38 percent. If this information is confirmed, it will mean that sea drones not only damage individual individuals, but also affect the rhythm of Russian oil exports.

This is why it is no longer just a description of combat activities. We are dealing with an industrial pressure tool: relatively cheap, difficult to stop completely and extremely costly to the opponent, who must defend the entire oil transport chain.

The sea is no longer a safe haven

Russia will have to face rising costs of protecting tankers. Insurance rates will increase, there will be a need to direct maritime forces to escort, to speed up the re-registration of units. Each of these reactions means cost. Each weakens the comfort with which Russian oil has been through gaps so far Western sanctions.

Ukraine has shown a simple and uncomfortable thing for Moscow: "the shadow float" is not untouchable. It is not enough to change the flag, documents and insurer when on the other side a state is able to produce sea drones on an industrial scale.

Over the years sanctions have been presented as a tool of diplomacy. Ukraine has shown that building pressure on Russia can look different: through production, technology and consistent activities at sea, as we are all witnessing today.
