Design and constructionEdit

She was a member of the first British class of submarines, although slightly bigger than the lead ship, HMS A1. 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.[1]


She flooded after running aground in Bomb Ketch Lake, Portsmouth harbour in January 1920 and was sold for scrap to H. G. Pound of Portsmouth on 22 October 1925.
