Ukrainian forces have struck a rare and prized Russian naval radar system mounted on a vehicle, according to a video released by a Ukrainian military unit. The footage purportedly shows Ukraine targeting a naval version of the Zaslon radar, which was originally developed for the MiG-31 interceptor aircraft.

KYIV—Ukraine said it downed two Russian jet fighters using sea drones equipped with modified U.S.-made missiles, in what military officials in Kyiv said is the first such attack in the history of warfare.

The Ukrainian Defence Intelligence Service reported on Saturday that a Ukrainian attack drone has shot down a Russian jet fighter for the first time. It reportedly shot down the SU-30 jet over the Black Sea.
