HMS A2 was an {{sclass2-|A|submarine (1903)|0}} submarine built for the Royal Navy in the first decade of the 20th century.

Design and description

A2 was a member of the first British class of submarines, although slightly larger, faster and more heavily armed than the lead ship, {{HMS|A1}}. The submarine had a length of {{convert|105|ft|1|in|m|1}} overall, a beam of {{convert|12|ft|9|in|m|1}} and a mean draft of {{convert|10|ft|8|in|m|1}}. They displaced {{convert|190|LT|t}} on the surface and {{convert|206|LT|t}} submerged. The A-class submarines had a crew of 2 officers and 11 ratings.^[1]

For surface running, the boats were powered by a single 16-cylinder {{convert|450|bhp|lk=in|0|adj=on}} Wolseley petrol engine that drove one propeller shaft. When submerged the propeller was driven by a {{convert|150|hp|0|adj=on}} electric motor. They could reach {{convert|10|kn|lk=in}} on the surface and {{convert|7|kn}} underwater. On the surface, A2 had a range of {{convert|320|nmi|lk=in}} at {{convert|10|kn}};^[1] submerged the boat had a range of {{convert|30|nmi|lk=in}} at {{convert|5|kn}}.^[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 Vickers, Barrow-in-Furness. She was launched on 15 April 1903. During World War I, A2 served on harbour service at Portsmouth.^[4] 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.
