Armament

HMS Andrew (P423/S23/S63), was an Amphion-class submarine of the Royal Navy, built by Vickers Armstrong and launched on 6 April 1946.

The submarine was fitted with a 4-inch (102 mm) deck gun in 1964 for service during the Indonesia–Malaysia confrontation to counter blockade-running junks.[1] The gun was fired for the last time in December 1974.[2] She was sold off in 1977 and was broken up.

Andrew was briefly the oldest Amphion-class submarine to remain in service, was the last British submarine with a deck gun, was the last British World War II-designed submarine in service, and was the first submarine to use a "snort" to cross the Atlantic (in May 1953).[3]

Like all Amphion-class submarines, Andrew 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.[4] 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).[4]

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).[5] 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).[4] She 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.[4]
