The Kashin class, Soviet designation Project 61, were series of anti-aircraft guided-missile destroyers built for the Soviet Navy since the 1960s. As of 2020, no ships remain in service with the Russian Navy, but three modified ships continue in service with the Indian Navy as Rajput-class destroyers.
In the Soviet Union they were officially classified as "guard ships" (storozhevoi korabl – SKR), then "large ASW ships" (BPK) or "large missile ships" (BRK), but in the rest of world they are commonly regarded as missile destroyers due to their size and armament. They were the first Soviet purpose-built anti-air warfare ships and the first to carry an ASW helicopter.
