Yahoo News From world war one to Aukus: how Australia’s submarines have evolved
28 February 1914: Australia’s first submarine, HMAS AE1, is commissioned in Portsmouth, UK before departing for Sydney.
14 September 1914: HMAS AE1 strikes the sea-floor while diving during deployment near Papua New Guinea during the first world war. All hands are lost.
30 April 1915: HMAS AE2, Australia’s second submarine, is scuttled by her crew after five days of operations during the Gallipoli campaign.
8 April 1919: Britain “gifts” six second-hand J-class submarines to Australia. The ships are largely obsolete and in bad shape by the time they arrive. By 1924 they are sold off for scrap.
1 April 1927: HMAS Oxley is commissioned. Oxley and her sister boat HMAS Otway are modified British O-class submarines but after arriving in Sydney in 1929 they are returned in 1931 due to maintenance problems.
14 June 1952: The US Navy begins construction of the first nuclear-powered submarine, USS Nautilus, in Connecticut. The submarine is launched 18 months later.
9 August 1957: The Soviet Union launches its first nuclear-powered submarine, K-3 Leninsky Komsomol.
22 January 1963: The revived Australian Submarine Service orders eight British Oberon-class submarines, though the order is later reduced to six. Over the next two decades of operation, Australia relies on the UK as a “parent navy” for 85-90% of maintenance, with refits costing 76% of the purchase price.
10 April 1963: USS Thresher becomes the first nuclear submarine to sink with the loss of all 129 on board after a mechanical failure causes it to sink to crush depth.
May 1983: The newly elected Labor government puts out the first tenders soliciting proposals for the Collins-class submarine.
3 June 1987: A $5bn contract is signed to build six Collins-class submarines. Each submarine is to be built in six sections with Australian companies contributing 60% of the work.
29 June 1987: The Australian Submarine Corporation site in Osborne, Adelaide is selected as the facility to build the new submarines. The site is opened by Australia’s then prime minister Bob Hawke on November 1989.
February 1990: Work on HMAS Collins begins. Named after V-Adm Sir John Collins, the Collins class is a Type 471 diesel-electric submarine designed by Swedish shipbuilders Kockums.
28 August 1993: HMAS Collins is launched but not commissioned until 1996 as the ship is incomplete, with internal piping and fittings not yet installed. Sections of the hull are fitted with wood and painted black in preparation for photographs to be taken on launch. It will not be completed until June 1994.

Doubt looms over whether the next generation of submarines will be built locally and months of confusion follow about the future of the program.
9 February 2015: The then prime minister Tony Abbott announces a “competitive evaluation process” will take bids for new plans to build Australia’s next generation of submarines. Japan, France and Germany enter the running. Speculation over the details, location of the build and who will be preferred reigns.
