Ukraine said it sank a $65 million warship that Russia planned to use for an antiaircraft missile system

• Ukraine said it destroyed another Russian ship in the Black Sea using sea drones.
• The Sergei Kotov patrol vessel, part of Russia's Black Sea Fleet, cost $65 million, Ukraine said.

Ukrainian military intelligence said a $65 million Russian warship was the latest to be sunk in the Black Sea.

The Main Directorate of Intelligence of the Ministry of Defense of Ukraine said Tuesday that the vessel, the Sergei Kotov, was destroyed overnight.

The ship was worth about $65 million, it said.

It added that a Ukrainian special unit attacked the Black Sea Fleet vessel in cooperation with Ukraine's navy and the Ministry of Digital Transformation.

An intelligence source told Ukraine's Kyiv Post that Magura V5 drones struck the ship while it was patrolling in the Kerch Strait and that it sank.

Andrii Yusov, a Ukrainian intelligence official, told Radio Free Europe that Russia was planning to put an antiaircraft missile system on the ship.

Ukraine shared footage of what's said to be the attack.

The hit, if confirmed, would be another victory for Ukraine in the Black Sea, despite it not having any warships of its own.

The Sergei Kotov is a patrol ship operating as part of Russia's Black Sea Fleet, according to The Kyiv Independent.

Ukraine has been targeting Russian ships since the start of Russia's full-scale invasion in February 2022, damaging, destroying, or sinking many of them.

Ukraine has targeted Russian vessels with commando raids, missiles, and sea drones, including ones it developed itself.

In December, the UK's defense minister said: "Over the past 4 months 20% of Russia's Black Sea Fleet has been destroyed."

Russia has moved many of its vessels away from Sevastopol, its major Black Sea port in Crimea, to areas farther away from Ukraine.

Russia annexed the Crimean Peninsula in February 2014. Ukraine has repeatedly vowed to take it back and has launched long-range attacks on infrastructure there.
