HMAS ''Dechaineux'' (SSG 76) is the fourth of six ''Collins'' class submarines operated by the Royal Australian Navy (RAN). Named for Captain Emile Dechaineux, the boat was laid down in 1993 and launched in 1998. ''Dechaineux'' and sister boat ''Sheean'' were modified during construction as part of the "fast track" program—an attempt to fix the problems affecting the ''Collins'' class, and put at least two fully operational submarines in service before the last ''Oberon'' class submarine was decommissioned. In 2003, a seawater pipe burst while ''Dechaineux'' was submerged deep, nearly resulting in the loss of the submarine. ==Construction== ''Dechaineux'' was laid down by the Australian Submarine Corporation on 4 March 1993, launched on 12 March 1998, and commissioned into the RAN on 23 February 2001.〔 The issues with the ''Collins'' class highlighted in the McIntosh-Prescott Report and the pressing need to have combat-ready submarines in the RAN fleet with the pending decommissioning of , the final ''Oberon'' class submarine in Australian service, prompted the establishment of an A$1 billion program to bring ''Dechaineux'' and sister boat ''Sheean'' up to an operational standard as quickly as possible, referred to as the "fast track" or "get well" program.〔Yule & Woolner, ''The Collins Class Submarine Story'', pp. 288-9〕 The fast track program required the installation of reliable diesel engines, fixing the hydrodynamic noise issues with the class by modifying the hull design and propeller, and providing a functional combat system.〔Yule & Woolner, ''The Collins Class Submarine Story'', pp. 291-4〕 The original Rockwell International-designed combat system had been cancelled, but because there wasn't enough time to evaluate the replacement system to include it in the "fast track" program, the two submarines were fitted with components from the old Rockwell system, which were augmented by commercial off-the-shelf hardware and software.〔Yule & Woolner, ''The Collins Class Submarine Story'', pp. 292-4〕 Even with the enhanced Rockwell system, it was believed that the capabilities of the fast track ''Collins'' boats was only equivalent to the ''Oberons''.〔Yule & Woolner, ''The Collins Class Submarine Story'', p. 294〕 On 14 December 2000, ''Dechaineux'' and ''Sheean'' arrived at HMAS ''Stirling'', following the completion of sea trials.〔Yule & Woolner, ''The Collins Class Submarine Story'', p. 298〕 ''Dechaineux'' was named for Captain Emile Dechaineux, who was killed by a kamikaze attack on 21 October 1944 while commanding .〔Yule & Woolner, ''The Collins Class Submarine Story'', p. 340〕 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 Dechaineux (SSG 76)」の詳細全文を読む スポンサード リンク
