For size, the R-73 Archer is 9’7” long, so the USV seems to be about 20ft/6mlong.
In the Black Sea, Russian forces spotted a Ukrainian USV armed with a twin rail launcher for R-73 all-aspect IR homing air-to-air missiles.
Based on the footage, some Ukrainian USVs now possess a nascent SAM capability, likely able to target low and slow Russian helicopters.
