HMAS AE2

HMAS AE2

HMAS AE2 (originally known as 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. The boat then sailed to Australia in what was, at the time, the longest voyage ever undertaken by a submarine.

After the start of World War I, AE2 was sent to German New Guinea with the Australian Naval and Military Expeditionary Force, then spent time patrolling around Fiji. With no need for submarines in the Pacific or Indian theatres, AE2 was towed to the Mediterranean, and arrived off Egypt in early 1915. The boat was assigned to the Dardanelles Campaign, and was the first submarine to successfully penetrate the waterway. With orders to "run amok" inside Turkish territory, AE2 operated for five days before mechanical faults forced her to the surface, where she was damaged by the torpedo boat Sultanhisar. The submarine was scuttled by her crew, all of whom were captured.

AE2 was the only RAN vessel lost to enemy action during World War I. The Rahmi M. Koç Museum began searching for the wreck in 1995, and found it in 1998. As of 2007, the Australian and Turkish navies were investigating ways to refloat and preserve the submarine.
