K-51 Verkhoturye (Russian: К-51 Верхотурье) is the lead submarine of the Project 667BDRM Delfin class (NATO reporting name: Delta IV) nuclear-powered ballistic missile submarines currently in service with the Russian Navy.[1] It was built at the Sevmash shipbuilding company in Severodvinsk between 1981 and 1984 and was commissioned in 1984. It is named after the city of Verkhoturye.

Description

K-51 Verkhoturye has a length of 167.4 m (549 ft)

draft of 8.8 m (29 ft). It displaces 18,200 tonnes (17,900 long tons; 20,100 short tons) and can dive up to 550–650 m (1,800–2,130 ft). It carries a complement of 135–140 sailors.[2][3][4]

Two VM-4 180 MW (240,000 hp) pressurized water reactors power the submarine, and drive two shafts with seven-bladed fixed-pitch propellers. They propel the submarine to the maximum speed of 14 knots (26 km/h; 16 mph) when surfaced and 24 knots (44 km/h; 28 mph) when submerged.[2][3]

The boat's primary armament are the 16

submarine-launched ballistic missiles which have the range of 8,300 km (5,200 mi). It also has four 533 mm bow tubes which can launch RPK-7 Veter anti-ship cruise missiles, and up to 12-18 torpedoes or 24 mines.[2][4][5]

Construction and service

Verkhoturye is the first submarine of the Delta-IV class. It was built at the

submarine launched ballistic missile during 1985–1986. Between 2–29 September, it became the first submarine of the class to cruise to the Arctic Ocean while carrying missiles.[4]
After the Soviet Union's dissolution in 1991, the boat was transferred to the Russian Navy.

It underwent modernization twice, first in 1999, and then between 2010 and 2012. It re-entered service in December 2012 after the re-fit.[6]
