Soviet cruiser Groznyy

Displacing 4,350 tonnes (4,280 long tons) standard and 5,300 tonnes (5,200 long tons; 5,800 short tons) full load, Groznyy was 142.7 m (468 ft 2 in) in length.[1] Power was provided by two 45,000 horsepower (34,000 kW) TV-12 steam turbines, fuelled by four KVN-95/64 boilers and driving two fixed pitch screws. Design speed was 34 knots (63 km/h; 39 mph), which the ship exceeded.[2]

The ship was designed for anti-ship warfare around two quadruple SM-70 P-35 launchers for sixteen 4K44 missiles (NATO reporting name SS-N-3 'Shaddock').[3] To defend against aircraft, the ship was equipped with a single twin ZIF-102 M-1 Volna launcher with sixteen V-600 4K90 (SA-N-1 'Goa') missiles forward and two twin 76 mm (3 in) guns aft, backed up by two single 45 mm (2 in) guns.[3] Defence against submarines was provided by two triple 533 mm (21 in) torpedoes and a pair of RBU-6000 213 mm (8 in) anti-submarine rocket launchers.[1]

In 1975, the missiles were updated, the main radar was upgraded to MR-310A and two Uspekh-U radars were added.[3] Four AK-630 close-in weapon systems were also added in the 1980s to improve anti-missile defence.[2]

Launched on 26 March 1961, Groznyy was initially accepted into the Northern Fleet.[3] After visits from General Secretary Nikita Khrushchev and Admiral Sergey Gorshkov on 4 May 1962, the ship undertook tests that culminated in the successful launch of two P-35 missiles in front of Khrushchev on 22 July.[4] The ship undertook the first successful deck landing and take off of the mid-course guidance derivative of the Kamov Ka-25 in 1966 and was transferred to the Black Sea Fleet on 5 October that year.[3]

The ship served globally, including visits to Varna, Bulgaria, in August 1967, Tartus, Syria, in 1968, Havana, Cuba, in June 1969, Fort-de-France, Martinique, in August 1969, Split, Yugoslavia, and Alexandria, Egypt, in 1972, Casablanca, Morocco, in April 1972, Marseille, France, in July 1973, Tobruk, Libya, in November 1985, Rostock, East Germany, in July 1987 and Szczecin, Poland, in July 1988.[4] Groznyy took part in the "Atlantika-84" exercise in the Barents and Norwegian Seas in March 1984 and tracked US Navy task forces led by the aircraft carriers USS Coral Sea and USS Saratoga as part of operations in the Mediterranean Sea between 9 August 1985 and 4 February 1986.[4]
