Bars RS-1 is a Ukrainian long-range jet-powered one-way attack UAV, often described in local reporting as a drone-missile or cruise-missile-like unmanned system. Public sources identify it as part of Ukraine's domestically developed deep-strike inventory, with direct official reporting placing RS-1 Bars in the May 2026 Moscow-region strike package and later defense reporting describing a Bars RS variant with a larger fuel tank, higher takeoff weight, and 1,000 km class use claims.
