HMAS AE2 was an E-class submarine of the Royal Australian Navy (RAN). One of two submarines ordered for the fledgling navy, AE2 was built by Vickers Armstrong in England and was commissioned into the RAN in 1914. Together with her sister submarine, HMAS AE1, the boat then sailed to Australia in what was, at the time, the longest voyage ever undertaken by a submarine.

British E-class submarine
The British E-class submarines started out as improved versions of the British D-class submarine. The E class served with the Royal Navy throughout World War I as the backbone of the submarine fleet. The last surviving E class submarines were withdrawn from service by 1922.
