The SBU — Ukraine's security service — has retooled its Sea Baby strike boat to carry six to eight fiber optic linked FPV attack drones into compartments on each side. The Black Sea just became a floating FPV arsenal — and U.S.
Sea Baby is no longer the weapon. The SBU (Ukraine's security service) strike boat now carries six to eight first-person-view attack drones into compartments on each side and launches them like a shotgun. The Black Sea is becoming a floating FPV arsenal.
The retooling is grounded in a specific operational record. Russian accounts around Kinburn Spit, roughly 40 miles east of Odesa, describe Sea Baby arriving offshore with Shmel thermobaric rockets and a side payload of FPVs, according to Forbes reporting drawing on those accounts. The boats are no longer being used as their own weapon. They are being used to deliver one.
The retooling tracks a concrete design problem. Ordinary FPVs, the cheap first-person-view craft that have defined the ground war, depend on a radio link between operator and airframe. Russia's dense jamming environment over the Black Sea has made that link unreliable at the kind of standoff range Sea Baby wants to operate. Some of the drones in those compartments now trail a fiber-optic cable back to the launcher, leaving them unable to be jammed at all. In October 2025, sea drones launching those fiber-optic-tethered FPVs hit the Russian ports of Tuapse and Novorossiysk, per Forbes reporting on the operations.
The pattern extends past Sea Baby. Defense News tracks Ukraine's larger project of turning every unmanned platform it fields, including surface drones, ground robots, and submarines, into FPV launchers. Other reporting in the same outlet frames the trajectory: in October 2025, Ukraine unveiled an upgraded sea-drone design for Black Sea strike missions; in December 2025, Kyiv pulled off what Defense News called the war's first underwater drone strike, captured on hacked Russian cameras. The whole sea drone fleet is being treated as a magazine of small attack drones.
Sea Baby's reach is why the doctrine now matters beyond Ukraine. The vessel's stated range, roughly 930 miles (1,500 kilometers) carrying about 4,400 pounds (2,000 kilograms) of payload, would let an unmanned boat launch inside Russian air defenses while keeping Russian targets far from land-based launchers. Caveat: that figure is an SBU estimate, not an independent measurement. Even so, the design logic of a low-cost expendable boat firing small jam-resistant drones fits an older naval problem: how to threaten a defended coast without sending a manned ship.
That is the logic U.S. naval analysts are now studying. The Center for Strategic and International Studies has argued the U.S. military's drone playbook should learn directly from Ukraine's improvised doctrine. The U.S. Naval Institute's Proceedings wrote that Ukraine's separate Magura-class naval drones, run by military intelligence (GUR) rather than the SBU, have acted as Black Sea "equalizers" against a much larger Russian fleet. Sea Baby and Magura are different boats from different agencies. What travels is the shared doctrine: cheap, expendable, hard-to-jam craft fired at defended targets.
That is the part to watch. A six-to-eight-FPV payload is small, but it is portable: any boat, ground robot, or undersea vessel that fits one compartment becomes a credible strike option. If U.S. or allied planners absorb even part of that template, the next naval standoff in the Pacific or the Mediterranean will not look like the last one. It will look like a coast trying to jam a thousand tethered cameras, while a hangar of FPVs comes at it from every available platform.
That hangar is already on the water near Kinburn Spit, where Russian accounts of the Sea Baby configuration first surfaced. Whether the doctrine crosses oceans before the boat does is the next question to track.
