Ukrainian explosive naval drones are documented in the 2014 Russia-Ukraine War through official Ukrainian intelligence and security-service statements, as well as reporting from the Associated Press. Defence Intelligence of Ukraine identifies MAGURA unmanned marine vehicles as strike sea drones used by its Group 13 unit against Russian Black Sea Fleet vessels and lists a sequence of attacks from May 2023 through June 2024.
The Security Service of Ukraine separately identifies Sea Baby as an SBU-developed sea-drone line used in high-profile operations, including the July 2023 Crimean Bridge attack and strikes on Russian naval targets such as Olenegorsky Gornyak and the SIG tanker. Associated Press reporting later described SBU Sea Baby drones as unmanned naval craft used to target Russian shipping and infrastructure in the Black Sea.

Narrative
The Ukrainian naval-drone record covers more than one craft line rather than a single standardized model. MAGURA V5 is publicly associated with DIU operations and is documented in anti-ship attacks against Russian Black Sea Fleet vessels, patrol craft, and other maritime targets. Sea Baby is publicly associated with the SBU and is documented in attacks on maritime infrastructure and Russian shipping in the Black Sea.
These craft gave Ukraine a maritime strike option despite Russia's larger conventional fleet. The documented uses center on one-way explosive attacks, sea denial, and interdiction against ships, patrol craft, bridge infrastructure, repair facilities, and coastal positions. Later public reporting and SBU-linked statements describe expanded Sea Baby configurations with heavier payloads, multiple-rocket launchers, machine-gun turrets, and longer reach, but the core conflict-use evidence remains the documented Ukrainian use of unmanned naval craft against Russian maritime targets.
