Ukrainian UUV Blast Cripples Kilo-Class Sub in Novorossiysk Harbor
On 15-16 Dec 2025 a Ukrainian ‘Sub Sea Baby’ unmanned underwater drone slipped past harbor defenses and detonated beside a moored Russian Project 636.3 submarine in Novorossiysk, the first documented combat strike by a UUV on a submarine; Russia insists the boat is unhurt.
Focusing Facts
- Planet Labs 16 Dec satellite imagery shows the same Kilo-class hull riding lower and pier sections blackened after the explosion recorded on hacked CCTV.
- Because Turkey closed the Bosphorus to Russian warships in Feb 2022, the damaged sub cannot reach the only full overhaul yard at Kronstadt, leaving no suitable repair facility in the Black Sea.
- Eliminating one Varshavyanka would cut the Black Sea Fleet’s Kalibr launch capacity by about 10 %, from 40 to 36 tubes.
Context
Harbor raids using cheap unmanned craft echo the 1915 Dardanelles minefields that neutralized dreadnoughts at a fraction of the cost, yet this time the threat moves underwater and autonomous. Over the past decade war-fighting has trended toward swarms, sensors and precision micro-munitions eroding the value of capital ships—much as aircraft carriers relegated battleships after 1941. If a mid-income state can sideline a $400-500 million submarine with a remote-controlled charge, navies everywhere must rethink survivability, logistics and chokepoint dependence; the Bosphorus closure turned geography into a force multiplier for Kyiv. On a 100-year arc, the episode signals a gradual shift from concentrated, manned blue-water fleets toward dispersed, unmanned, attritable systems—potentially upending doctrines of sea control and nuclear deterrence that have stood since the Cold War.
Perspectives
Ukrainian and pro-Ukraine media
e.g., Euromaidan Press, KyivPost, Ukrainska Pravda — Report the Sub Sea Baby raid as a confirmed, highly successful strike that crippled the Black Sea Fleets Kilo-class submarine and slashed Russias Kalibr launch capacity. Coverage leans on SBU footage and Ukrainian officials to declare Kremlin denials almost certainly false , reflecting a patriotic incentive to amplify Ukrainian victories and downplay the lack of fully independent damage verification.
Defense-oriented international outlets with an Asian/Middle-East focus
e.g., EurAsian Times/Latest Asian News — Frame the incident as a watershed moment proving unmanned underwater drones can neutralise major submarines, heralding a new era of naval warfare even while noting Moscows flat denial. By spotlighting global strategic ramifications and future UUV arms races, these outlets sensationalise the tech angle and extrapolate far-reaching consequences despite conceding that the actual damage could not be independently verified .
Western public-service broadcasters exercising strict verification standards
e.g., BBC — Acknowledge Ukraines claim and show the explosion video but stress that it is not clear whether a submarine has been hit and seek expert opinions while noting Russias statement of no damage. The caution to avoid premature conclusions may tilt toward equivocation, potentially underplaying credible OSINT indicators cited elsewhere in order to preserve a reputation for neutrality.
