She was a member of the first British A-class of submarines, although slightly bigger than the lead boat, HMS A1. She was built at Vickers, Barrow-in-Furness and was commissioned on 13 July 1904.

Left Portsmouth Harbour at 09.30 with several other ‘A’ & ‘C’ class submarines for exercises off Bembridge, Isle of Wight. The exercises had been in progress several hours when A-3 blew her tanks and surfaced directly in the path of the torpedo gunboat the 1070 ton HMS HAZARD. With a large hole torn in her side the A-3 sank to the seabed out of control drowning all 14 crew. She was raised five week later and moved into St Helen’s Bay, IOW. On the 12/03/1912 she was taken to Portsmouth and having been pumped out all 14 bodies were removed for burial at the Royal Naval Cemetery.
