Admiral Isachenkov was the seventh ship of the class of ten Project 1134A Berkut A (NATO reporting name Kresta II-class) cruisers, designed by Vasily Anikeyev.[1] They were designated as Large Anti-Submarine Ships in accordance with their primary mission of countering NATO submarines.[2]

As a Kresta II-class cruiser, Admiral Isachenkov was 156.5 metres (513.5 ft) long with a beam of 17.2 m (56.4 ft) and a draught of 5.96 m (19.6 ft). She displaced 5,600 tons standard, 6,500 tons light and 7,535 full load, and had a complement of 343. The ship was equipped with a hangar aft to carry a single Kamov Ka-25 Hormone-A helicopter[3]

Admiral Isachenkov was propelled by two TV-12 steam geared turbines powered by four high pressure boilers which created 75,000 kilowatts (100,577 hp), giving her a maximum speed of 34 knots (63 km/h; 39 mph). She had a range of 5,200 nmi (9,630 km; 5,984 mi) at 18 kn (33 km/h; 21 mph) and 1,754.86 nmi (3,250 km; 2,019 mi) at 32 kn (59 km/h; 37 mph).[1]

Armament

For her primary role as an anti-submarine cruiser, Admiral Isachenkov mounted two quadruple launchers for eight anti-submarine missiles in the Metel anti-ship complex. She was also equipped with two RBU-6000 12-barrel and two RBU-1000 6-barrel rocket launchers to protect against close-in threats.[4] The Ka-25 helicopter embarked on the cruiser was also capable of aiding in the search and destruction of submarines.[5]

Admiral Isachenkov was armed with four AK-725 57 mm (2.2 in) L/80 DP guns situated in two twin mountings to protect against aerial threats. The vessel also had four 30 mm (1.2 in) AK-630 CIWS mountings, and was armed with two twin launchers for the 48 V-611 surface-to-air missiles they carried in the M-11 Shtorm system. She also mounted two quintuple mountings for 533 mm (21 in) dual-role torpedoes.[4]

Electronics warfare

Admiral Isachenkov was equipped with the MR-600 Voskhod (NATO code name Top Sail) early warning air search radar, the MR-310U Angara-M (NATO code name Head Net C) search radar, and the Volga (NATO code names Don Kay and Don-2) navigational radar. For anti-submarine warfare she had improved MG-332T Titan-2T hull mounted sonar.[6] For fire control purposes she had Grom-M for the surface-to-air missiles, MR-103 Bars for the AK725 and MR-123 Vympel for the AK-630.[1] Admiral Isachenkov also had a MG-26 communications outfit and a MG-35 Shtil sonar.[6]

Construction

Built in the Zhdanov Shipyard with the serial number 727, Admiral Isachenkov, named for Soviet deputy for shipbuilding and armaments Nikolai Isachenkov whose leadership led to the development of this class of warships, was laid down on 30 October 1970 and launched on 28 March 1972.[7]
