HMS Auriga (P419)

HMS Auriga (P419/S69), was an Amphion-class submarine of the Royal Navy, built by Vickers Armstrong and launched 29 March 1945.

Design
Auriga had a displacement of 1360 LT when at the surface and 1590 LT while submerged. It had a total length of 293 ft, a beam of 22 ft, and a draught of 18 ft. The submarine was powered by two Admiralty ML eight-cylinder diesel engines generating 2150 hp each. Four electric motors each producing 625 hp drove two shafts. It could carry a maximum of 219 LT of diesel, although it usually carried between 159 and 165 LT.

The submarine had a maximum surface speed of 18.5 kn and a submerged speed of 8 kn. When submerged, it could operate at 3 kn for 90 nmi or at 8 kn for 16 nmi. Surfaced, it could travel 15200 nmi at 10 kn or 10500 nmi at 11 kn. Armament was ten 21 in torpedo tubes, one QF 4 inch naval gun Mk XXIII, one Oerlikon 20 mm cannon, and a .303 British Vickers machine gun. Its torpedo tubes were fitted to the bow and stern, and it could carry twenty torpedoes. Its complement was sixty-one crew members.

Service history
In 1953 she took part in the Fleet Review to celebrate the Coronation of Elizabeth II. In March 1961, the submarine was among the vessels that took part in a combined naval exercise with the United States Navy off Nova Scotia. Auriga departed Canada on 25 April 1961 after completing an 18-month tour with the Sixth Submarine Division at Halifax, Nova Scotia.
