Our History
The Royal Australian Navy Submarine Service has been established four times since 1914, with the initial three attempts being foiled by combat losses and Australia's economic problems. The modern Submarine Service was established in 1964, and has formed an important element of the Australian military's capacity since that date. While the Submarine Service has not seen combat since World War I, Australian submarines have conducted extensive surveillance operations throughout South East Asia.
1914-1945
After the formation of the Royal Australian Navy upon Federation, a period of uncertainty had followed as the size of the force to be established was determined. Eventually, this was set at 13 vessels, including three submarines. Initially, it had been intended to purchase three small submarines, but this order was later changed, and instead Australia's first submarines were the larger British E class submarines AE1 and AE2. These submarines were built in Britain and arrived in Australia in 1914. Following the outbreak of World War I, both boats took part in the occupation of Rabaul in German New Guinea in September 1914. During this operation, AE1 disappeared on 14 September off Cape Gazelle, New Britain. It is probable that she was wrecked on a reef during a practice dive, but she is yet to be found.
AE2 remained in the South Pacific until December 1914, when she was ordered to the Mediterranean to support the British-led operations off the Gallipolipoli peninsula in Turkey. AE2 was the first Australian submarine to penetrate the Dardanelles, achieving this task on 25 April 1915. AE2 operated in the Sea of Marmora for five days and made four unsuccessful attacks on Turkish ships before being damaged by a Turkish gunboat and scuttled by her crew on 30 April. These attacks are the only occasions an Australian submarine has fired in anger.
HMAS Platypus with all six J Class submarinesThe Australian submarine service was reformed in 1919, when the British government transferred six J Class submarines to Australia; HMA Submarines J1,J2, J3, J4, J5, and J7. These submarines arrived in Australia with their tender HMAS Platypus in April 1919 and were based at Osborne House, Geelong from early 1920. The boats were in poor mechanical condition, however, and spent most of their service in refit. Due to Australia's worsening economic situation, all of the boats were decommissioned in 1922, and were scuttled later in the decade.
The Australian submarine service was established a third time in 1927, when the O Class submarines HMAS Oxley and HMAS Otway were commissioned. These submarines sailed from Portsmouth for Sydney on 8 February 1928, but did not arrive in Australia until 14 February 1929; numerous mechanical problems delayed their delivery voyage. Due to Australia's poor economic situation, the O Class boats proved to be unaffordable and were placed in reserve in 1930, before transferring back to the Royal Navy in 1931. As a result, the Royal Australian Navy did not operate any submarines during World War II, though the obsolete Dutch submarine K.IX was commissioned as HMAS K9 on 22 June 1943 and was used for anti-submarine warfare training purposes. Due to the boat's poor mechanical condition HMAS K9 saw little service with the RAN and spent most of her time in commission under repair, before being decommissioned on 31 March 1944 due to a lack of spare parts.
WWII Operations in Australia
The Australian ports of Fremantle and Brisbane were important bases for Allied submarines during World War II. A total of 122 United States Navy, 31 Royal Navy, and 11 Royal Netherlands Navy submarines conducted patrols from Australian bases between 1942 and 1945. Fremantle was the second largest Allied submarine base in the Pacific Theatre after Pearl Harbor, Hawaii.
RN Submarines in AustraliaFollowing World War II the Royal Navy's 4th Submarine Flotilla was based in Sydney from 1949 until 1969. The flotilla, which varied in size between two and three boats, was used to support the Royal Australian Navy and Royal New Zealand Navy in anti-submarine warfare training, with the operating cost split between the two nations. In the early 1960s, the British Government advised the Australian Government that reductions in the Royal Navy conventional submarine force meant that the 4th Flotilla was to return to the United Kingdom. The impending withdrawal of the British submarine flotilla sparked the fourth attempt to establish an Australian submarine service. While the Department of Defence advised the government that three to six submarines should be purchased for training purposes, following the intervention of then-Senator John Gorton the Government instead approved the purchase of eight submarines to form a submarine strike force. Eight British Oberon class submarines were ordered in 1964, to be built in Scotland in two batches of four boats. Only six boats were delivered; the seventh and eighth were cancelled in 1971 to fund the acquisition of ten A-4 Skyhawk aircraft for the Fleet Air Arm. The final Royal Navy submarine to be based in Australia, HMS Trump, was withdrawn in 1969.
The Oberon Era
The first Australian Oberon class submarine, HMAS Oxley, was commissioned on 21 March 1967. She was followed by her sister ships; Otway (1968), Ovens (1969), Onslow (1969), Orion (1977), and Otama (1978). Orion and Otama were more capable than the previous four boats, as they were fitted with advanced communications monitoring equipment.
All of the Oberon class submarines were based at HMAS Platypus, on Sydney Harbour. The Oberons proved very successful and saw extensive service during the last decades of the Cold War. This service included conducting risky surveillance missions against India and Communist nations in South East Asia. The Oberon class are also reported to have regularly conducted operations with special forces from the Special Air Service Regiment and 1st Commando Regiment. As part of the Government's Two Ocean Navy policy submarines were homeported at HMAS Stirling in West Australia from 1987 and the headquarters of the Australian Submarine Squadron moved to HMAS Stirling in 1994. The Oberon class boats were gradually decommissioned and replaced with new Collins class submarines during the 1990s. The final Oberon class boat, HMAS Otama, was decommissioned on 15 December 2000.
The Collins Class
The six Collins class submarines were the first Australian-built submarines, and the most expensive ships to have been built in Australia. The Collins class submarines were built by the Australian Submarine Corporation at Adelaide, South Australia and entered service between 1996 and 2003 following extensive trials and modifications to the early boats in the class. The dedicated trials and submarine rescue ship HMAS Protector supported these trials between 1992 and 1998. Tests conducted on HMAS Collins after she was provisionally commissioned in 1996 revealed shortcomings in the submarine's performance, including excessive hull noise and an ineffective combat system. This is not unusual in the first of class of any ship. These problems were subsequently rectified and the Collins class submarines currently rank among the most effective conventional submarines in the world.
Like the Oberon class, the Collins class submarines are fitted to conduct surveillance patrols. The Collins class also has the capability to insert special forces teams whilst submerged, representing an improvement over the Oberons which were restricted to doing so whilst surfaced, usually at night. While the Collins class submarines' performance has improved over time, their maximum diving depth was permanently reduced following the near-loss of HMAS Dechaineux when a pipe burst during a practice dive in February 2003.
In 1998 the Royal Australian Navy became the fourth Navy in the world to permit women to serve onboard submarines. The first female submariners began their training at the Submarine Training and Systems Centre in June 1998.
The Next Generation
In December 2007 the Australian Government authorised the Navy to begin planning for the Collins class' replacement. The Navy researched options for the submarines and the government selected a French Design. On 26 April 2016, Prime Minister Malcolm Turnbull announced the Shortfin Barracuda, a conventionally-powered variant of the Barracuda-class nuclear submarine by French firm DCNS, as the winner.
