Sea Baby USV
Sea Baby is a Ukrainian naval unmanned surface vehicle developed and operated by the Security Service of Ukraine for long-range strike missions in the Black Sea. Official Ukrainian sources describe it as a small, fast USV able to carry a large explosive load over about 1,000 kilometers, giving Ukraine a domestically built means to attack Russian ships, port targets, and bridge infrastructure despite limited conventional naval forces.

MAGURA V5Unmanned surface vesselThe MAGURA V5 is a Ukrainian unmanned surface vessel built for reconnaissance, patrol, mine-warfare, fleet-security, and strike missions. In the Russia-Ukraine War it became one of Ukraine's best documented naval drones, used by Defence Intelligence units for long-range Black Sea attacks against Russian naval vessels.Ukrainian Explosive Naval DronesExplosive unmanned surface vesselUkrainian explosive naval drones are low-profile unmanned surface vessels developed during the Russia-Ukraine War to extend Ukrainian strike reach in the Black Sea. The family includes MAGURA V5 drones associated with Defence Intelligence of Ukraine operations and Sea Baby drones associated with the Security Service of Ukraine, pairing remote or semi-autonomous control with large explosive payloads for attacks on Russian naval targets..jpg?width=480)
Arash-2Long-range one-way attack UAV / loitering munitionThe Arash-2 is an Iranian long-range one-way attack UAV, also described as a loitering munition or suicide drone, associated with the Islamic Republic of Iran Army Ground Forces. Open sources describe it as a larger Arash/Kian-family strike system with rocket-assisted launch, reported passive-radar or seeker options, and claimed ranges up to about 2,000 km for attacks on fixed or emitting targets.

ForpostReconnaissance and strike unmanned aerial vehicleForpost is Russia's license-built and later indigenized derivative of the Israeli IAI Searcher II UAV, used for reconnaissance, target acquisition, artillery-fire adjustment, and in Forpost-R form armed strike missions. In the Russia-Ukraine War, Russian forces have used Forpost-R aircraft as higher-value reusable UAVs for surveillance and precision attack roles rather than expendable one-way drones.
Grad-armed Sea Baby dronesRocket-armed unmanned surface vesselGrad-armed Sea Baby drones are Ukrainian Security Service unmanned surface vessels adapted from the Sea Baby naval drone into a reusable coastal-strike platform. The variant replaces or supplements the explosive-boat role with a compact launcher for 122 mm Grad rockets, allowing Ukrainian operators to fire from the sea at shore targets such as Russian positions on the Kinburn Spit while retaining the Sea Baby platform's long range and high-speed unmanned surface-vehicle profile.Sources
