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. Together with her sister submarine, , 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 and enter the Sea of Marmara. 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. After another expedition in 2008, the Australian and Turkish Governments decided to leave the boat in place. ==Description== The ''E''-class was a version of the preceding ''D''-class submarine enlarged to accommodate an additional pair of broadside torpedo tubes.〔Harrison, Chapter 4: ''Pre-1914 Saddle Tank Types D & E Classes''〕 ''AE2'' was long overall, had a beam of and a draught of .〔 She displaced on the surface〔Frame, ''No Pleasure Cruise'', p. 97〕 and submerged. The ''E''-class boats had a designed diving depth of , but the addition of watertight bulkheads strengthened the hull and increased the actual diving depth to .〔 The crew consisted of 34 officers and ratings.〔Gillette, ''Australian & New Zealand Warships, 1914–1945'', p. 47〕 The boat had two propellers, each of which was driven by an eight-cylinder,〔 diesel engine as well as a electric motor. This arrangement gave the ''E''-class submarines a maximum speed of while surfaced and submerged.〔 They carried approximately 〔 of fuel oil that gave them a range of at while on the surface〔 and at while submerged.〔 ''AE2'' had four 18-inch torpedo tubes, one each in the bow and stern, plus two on the broadside, one firing to port and the other to starboard. The boat carried one spare torpedo for each tube. No guns were fitted.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「HMAS AE2」の詳細全文を読む スポンサード リンク
