HMS Sovereign (S108)
Type: nuclear attack submarine (SSN)
Keel laid: 18 September 1970, at Vickers Dockyard, Barrow-in-Furness
Launch: 17 February 1973
Commissioning: 11 July 1974
Length: 82,9 m
Width: 9,8 m
Height: ? m
Draught: 8,5 m
Displacement at surface: 3 500 t
Displacement below the surface: 4 500 (4 900) t
Max. 20 knots
Max. 30 knots
Surface range: unlimited
Underwater range: unlimited
Depth of dive: approx. 300 m
Propulsion: one Rolls Royce PWR1 pressurised water reactor, two steam turbines, auxiliary diesel-electric generator, 1 propeller
Endurance at sea: ? days
Crew: 116 of which 13 officers
Armament : 5 x 533 mm torpedo tubes forward
Supply of torpedoes : ? (Tigerfish and Spearfish torpedoes), also capable of launching SubHarpoon and Tomahawk missiles and laying mines
Electronic equipment:
Navigation radar
active/passive bow sonar
passive sonars on the sides
towed passive sonar
sonar to monitor the activity of foreign sonars
The design is based on the Valiant class, but thanks to a number of technical improvements, the submarines are quieter, faster and can dive deeper. In 1976, it surfaced at the North Pole. Still in service.
