HMS A2 was an A-class submarine built for the Royal Navy in the first decade of the 20th century.
Design and description
A2 was a member of the
draft of 10 feet 8 inches (3.3 m). They displaced 190 long tons (190 t) on the surface and 206 long tons (209 t) submerged. The A-class submarines had a crew of 2 officers and 9 ratings.[1]
For surface running, the boats were powered by a single 16-cylinder 450-
propeller shaft. When submerged the propeller was driven by a 150-horsepower (112 kW) electric motor. They could reach 10 knots (19 km/h; 12 mph) on the surface and 7 knots (13 km/h; 8.1 mph) underwater. On the surface, A2 had a range of 320 nautical miles (590 km; 370 mi) at 10 knots (19 km/h; 12 mph);[1] submerged the boat had a range of 30 nautical miles (56 km; 35 mi) at 5 knots (9.3 km/h; 5.8 mph).[2]
The boats were armed with two
18-inch (45 cm) torpedo tubes in the bow. They could carry a pair of reload torpedoes, but generally did not as doing so that they had to compensate for their weight by an equivalent weight of fuel.[3]
Construction and career
Like all boats in her class, she was built at
launched on 15 April 1903 and completed on 26 March 1904.[4] During World War I, A2 served on harbour service at Portsmouth.[5] She flooded after running aground in Bomb Ketch Lake in Portsmouth Harbour in January 1920 and was sold for scrap to H. G. Pound
of Portsmouth on 22 October 1925.
