Sea Baby
Ukrainian multipurpose USV used for self-destruct attacks and mine-laying.
The Sea Baby (Ukrainian: Морський малюк, romanized: Mors'kyi malyuk) is a multipurpose unmanned surface vehicle (USV) built for the Security Service of Ukraine (SBU) during the Russian invasion of Ukraine, which began in 2022. It can carry explosives for one-way attacks or be fitted for specialized tasks like hitting stationary targets—such as docked ships—or laying mines. The first designs came together in July 2022. By late 2023, later models featured backup communications systems and could carry warheads weighing up to 850 kilograms. The Sea Baby joined the 385th USV Brigade in August 2023, and in January 2024 the SBU showed a version armed with thermobaric launchers.

Facts from the source article.
Lore & Background
The Sea Baby was developed by the Security Service of Ukraine (SBU) after Brigadier General Ivan V. Lukashevych proposed the agency operate unmanned surface vehicles. Early USV models were designed in July 2022 in collaboration with specialists from the Ukrainian Navy and private companies, but the SBU later developed the Sea Baby independently. Unlike the smaller MAGURA V5 operated by the Main Directorate of Intelligence (GUR), the Sea Baby was designed primarily to strike static targets such as ships docked in port. Models from late 2023 used several redundant communications systems to avoid an incident where Starlink-dependent USVs were stranded after connectivity was declined by Elon Musk, and carried explosive warheads up to 850 kilograms.
Reader's Guide
The Sea Baby represents a significant evolution in naval drone warfare, demonstrating how a nation without a traditional navy can challenge a major fleet. Its development by the SBU, rather than private companies, highlights state-directed innovation in response to wartime needs. The use of redundant communications systems after the Starlink incident shows adaptation to technological vulnerabilities. The Sea Baby's role in striking the Crimean Bridge and forcing the Russian Black Sea Fleet to retreat to the eastern Black Sea underscores its strategic impact. The war has been described by scholars as the first 'drone war,' and Ukraine became the first country to create a military branch exclusively dedicated to drone warfare in June 2024. The Sea Baby's transformation from a self-destroying attack vehicle to a multipurpose platform capable of carrying thermobaric launchers, machine guns, and laying mines illustrates the rapid tactical evolution driven by the conflict.

The SBU is the primary operator, and the craft was formally assigned to the 385th USV Brigade starting in August 2023.
What can the Sea Baby actually do?
It can be loaded with explosives for one-way kamikaze runs against targets such as docked vessels, or configured to lay naval mines. Later versions from late 2023 could carry warheads of up to 850 kilograms and included redundant communication links.
What is the Sea Baby's most famous strike?
In July 2023, a Sea Baby was used in an attack on the Crimean Bridge, which became one of the most widely reported actions of the vehicle.
When was the Sea Baby first developed?
Initial designs were completed in July 2022, just months after the full-scale invasion began. By the end of 2023, the platform had been upgraded with backup comms and significantly heavier payloads.
