Sailors of the Caspian Flotilla reportedly repelled an attack by unmanned surface vessels (USVs) during exercises, with machine guns and grenade launchers opening fire on the craft. Some USVs lost propulsion, while others detonated. FPV drones also intercepted the vessels at a distance.

The exercises, which involved repelling the 'uninvited guests' in under twenty minutes, were closely monitored by Zvezdanews correspondent Mikhail Abroskin.
