Direct proof of use
Sea Baby is documented in Ukrainian service during the 2014 Russia-Ukraine War through Security Service of Ukraine attribution, Ukrainian government reporting, and independent press coverage. The SBU identified Sea Baby marine drones as its own development and linked them to the July 2023 Crimean Bridge attack and strikes on Russian naval targets including Olenegorsky Gornyak and the SIG tanker.
The same conflict-use record continued in 2024 when United24 reported that SBU Sea Baby boats had been fitted with Grad systems and tested with the Ukrainian Navy against Russian positions on the Kinburn Spit. The Kyiv Independent separately reported the same Grad-equipped Sea Baby claim from an SBU source, while noting that a video circulating with the report could not be independently verified by the outlet.

Timeline
The public record begins in 2023 with SBU statements and video-linked reporting around the Crimean Bridge attack and subsequent Black Sea targets. In May 2024, Ukrainian government and media reporting described Sea Baby as a platform that had expanded from explosive maritime strike missions into shore-attack use with Grad rockets.
Later reporting from an SBU demonstration in October 2025 described Sea Baby as a heavier multipurpose Black Sea platform with rocket-launcher and machine-gun variants. That later reporting supports the platform's evolution in the same war but is not treated here as proof for additional named attacks beyond the claims it directly documents.

Narrative
Sea Baby's documented conflict role is long-range maritime strike and coastal attack for Ukraine. In the 2023 reporting cluster, SBU head Vasyl Maliuk attributed Sea Baby use to attacks on fixed infrastructure and Russian vessels in the Black Sea theater. The named targets place the system in operations against the Kerch Strait connection to occupied Crimea and against Russian maritime logistics or naval assets.
The 2024 Grad-equipped reporting broadened the documented role from one-way surface attack to fire-support or shore-attack use. United24 said the boats were already actively involved in combat operations and had been used against Russian positions on the Kinburn Spit, a Russian-held coastal area at the mouth of the Dnipro-Bug estuary. The Kyiv Independent's account matched the core claim but attributed it to an unnamed SBU source and explicitly said it could not independently verify the associated video.
The clearest supported operator is Ukraine's Security Service, acting with Ukrainian naval forces in the Kinburn Spit episode as reported by United24. Public sources do not provide a complete inventory, sortie count, or battle-damage assessment for Sea Baby operations, so this record is limited to the named attacks and roles that the cited sources directly connect to the system.
