Like all Amphion-class submarines, Acheron had a displacement of 1,360 long tons (1,380 t) when at the surface and 1,590 long tons (1,620 t) while submerged. She had a total length of 293 feet 6 inches (89.46 m), a beam of 22 feet 4 inches (6.81 m), and a draught of 18 feet 1 inch (5.51 m). The submarine was powered by two Admiralty ML eight-cylinder diesel engines generating a power of 2,150 horsepower (1,600 kW) each. She also contained four electric motors each producing 625 horsepower (466 kW) that drove two shafts.[1] She could carry a maximum of 219 tonnes (241 short tons) of diesel, although she usually carried between 159 and 165 tonnes (175 and 182 short tons).[1]

The submarine had a maximum surface speed of 18.5 knots (34.3 km/h; 21.3 mph) and a submerged speed of 8 knots (15 km/h; 9.2 mph).[2] When submerged, she could operate at 3 knots (5.6 km/h; 3.5 mph) for 90 nautical miles (170 km; 100 mi) or at 8 knots (15 km/h; 9.2 mph) for 16 nautical miles (30 km; 18 mi). When surfaced, she was able to travel 15,200 nautical miles (28,200 km; 17,500 mi) at 10 knots (19 km/h; 12 mph) or 10,500 nautical miles (19,400 km; 12,100 mi) at 11 knots (20 km/h; 13 mph).[1] Acheron was fitted with ten 21 inches (530 mm) torpedo tubes, one QF 4 inch naval gun Mk XXIII, one Oerlikon 20 mm cannon, and a .303 British Vickers machine gun. Her torpedo tubes were fitted to the bow and stern, and she could carry twenty torpedoes. Her complement was sixty-one crew members.[1]

Service history

Acheron took part in the Coronation Review of the Fleet to celebrate the Coronation of Queen Elizabeth II in 1953.[3] she carried out 'General Naval Service' around the UK until the end of 1964. A geomagnetic storm in February 1956, during solar cycle 19, interfered with radio communications and prompted a search for the submarine after she lost radio contact.[4] From August to December 1959, she took part in a cruise to South Africa and Pakistan.[5]

She was decommissioned and broken up in 1972 at the yard of J Cashmore of Newport.[6]
