Russian missile ships have vacated the Black Sea, reports the Ukrainian navy. There are currently no ships from the Russian Federation's arsenal in the Black Sea or the Sea of Azov. The Ukrainian navy reports in a communiqué on Telegram that Russian ships have left the Black Sea.

Ukraine said it destroyed a Russian Mi-8 helicopter with a Magura V5 naval strike drone that was equipped with missile weapons.

The Ministry of Defense in the UK has revealed Project COOKSON, a new maritime drone initiative, seeking partners for development and deployment.

Missile-toting drone boats blew up two Russian helicopters and damaged a third in a Black Sea skirmish. Why it matters: Ukrainian outlets said the shoot-downs were world firsts. Engagements like this — especially with video evidence — leave little room for drone warfare naysayers.

The Russian Black Sea Fleet was defeated in a clash with a nation practically devoid of warships. The key to this victory was the essentially armed, remote-controlled Ukrainian water scooters, which continue to evolve.
