The Kashin class, Soviet designation Project 61, were series of anti-aircraft guided-missile destroyers built for the Soviet Navy since the 1960s. , 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.

Design

The design specification was approved in 1957; the first ship was laid down in 1959 and commissioned in 1962. Many new components were developed for these ships, including surface-to-air missiles, radars, and gas turbine engines. The gas turbines were arranged in two separate spaces and could be removed via the funnels for servicing. These were also the first Soviet ships designed to be closed down for nuclear fallout and had an operations room deep inside the ship rather than a large bridge. The final ship in the class, Sderzhanyy, was completed to a modified design as the Project 61M or 61MP (Kashin-Mod), being fitted with four SS-N-2C Styx anti-ship missiles, new towed-array sonar, a raised helipad and four close range AK-630 Gatling guns. The two RBU-1000 ASW rocket launchers were mounted aft, but later removed. Six ships were modernised to this standard in the 1970s. RUSSIAN DESTROYER Smetlivy was modernised (Project 01090) at Sevastopol in the early 1990s and fitted with new Kh-35 (SS-N-25 Switchblade, Harpoonski) anti-ship missiles and MNK-300 sonar. In 2020 she decommissioned and opened as a Museum at Sevastopol. The Rajput-class destroyer modification built for the Indian Navy has the aft gun turret replaced by a hangar for a helicopter, as well as SS-N-2C anti-ship missiles on the sides of the bridge.

Variants

Ships

In all, twenty ships were built for the Soviet Navy, one ship (ORP Warszawa (1988)) was later transferred to Poland, while five similar ships were built to a modified design for the Indian Navy as Rajput class.
