The Raduga KS-1 Comet (Russian: КС-1 "Комета" (Крылатый Снаряд: winged projectile), NATO reporting name: AS-1 Kennel) was a Soviet short range air-to-surface missile, primarily developed for anti-ship missions.

The AS-1 is believed to have entered service in 1955, initially being deployed on the Tu-4 and later on the Tu-16KS 'Badger-B' strategic bomber, on two under-wing pylons.

The system was designed for land based attacks on sea targets and widely deployed in eastern bloc countries such as Poland and East Germany during the Cold War.

With a 12 kiloton warhead and 180 km range it entered the equipment of Soviet and DDR forces in 1957.

[citation needed] Like the Sopka, cruising speed was achieved with a strap on SPRD-15 rocket,[6] but the FKR system allowed launch directly from the transporter, and the missile was modified to accept tactical nuclear warheads.
