Ship's badge of the RAN Submarine Service

The Royal Australian Navy Submarine Service is the collective name of the submarine element of the Royal Australian Navy. The service currently forms the Navy's Submarine Force Element Group (FEG) and consists of six Collins class submarines.

The Royal Australian Navy Submarine Service has been established four times, 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.

The current Director General Submarine Capability is Commodore G.J. Sammut, CSC, RAN.


The Royal Australian Navy's submarine service has been established four times since 1914.[1]

1914 to 1945

Australia's first submarines were the 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,[2] although as of 2008 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 Galipoli peninsula in Turkey. AE2 was the first British 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.[3]

HMAS Platypus with all five J Class submarines

The 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 five boats were decommissioned in 1922, and were scuttled later in the decade.[1]

The Australian submarine service was established a third time in 1927, when the British 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.[4][5] 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 22 June 1943 and 31 March 1944 and used for anti-submarine warfare training purposes.[6]

HMAS Oxley and Otway

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.[7]

1945 to present

Following 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.[8]

HMAS Onslow in 1998

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.[9] 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.[10] These missions were cancelled in 1992 when an Australian submarine, believed to be Otama, became tangled in fishing nets and was forced to surface in the South China Sea.[11] 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.[1][dead link]

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.[12]

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 serious shortcomings in the submarine's performance, including excessive hull noise and an ineffective combat system. These problems were subsequently rectified and the Collins class submarines currently rank among the most effective conventional submarines in the world.[13]

Like the Oberon class, the Collins class submarines have conducted surveillance patrols. These patrols have included collecting intelligence on East Timor ahead of the Australian-led intervention into the then-Indonesian province in 1999.[14] 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.[15]

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.[16]

The Submarine Service today

The Royal Australian Navy Submarine Force Element Group Headquarters, and all six of the Collins Class submarines, are at HMAS Stirling located in Rockingham, Western Australia. The majority of the Navy's submarine support facilities are also located at HMAS Stirling, including the Submarine Escape Training Facility. The LR5 submersible, which is contracted to provide the RAN's submarine rescue capability, has been based at nearby Henderson, Western Australia since June 2009.[17]

Under current Royal Australian Navy doctrine, the Submarine Service has the following responsibilities:[18]

  • intelligence collection and surveillance;
  • maritime strike and interdiction;
  • barrier operations;
  • advanced force operations;
  • layered defence;
  • interdiction of shipping;
  • containment by distraction; and
  • support to operations on land

In early 2007, it was reported that Submarine Service was experiencing severe shortfalls in personnel and had only 70% of its authorised strength of 500 sailors. These shortfalls were reported to have reduced the service's operational readiness and forced HMAS Collins to be temporarily withdrawn from service.[19]

Future submarines

The Collins class submarines will begin to reach the end of their useful life from 2026.[20] In order to meet the in-service date of 2026, advanced design work on the next generation of Australian submarines will begin by 2014–15. At this very early stage, it appears probable that the submarines will be Australian-built conventional submarines equipped with air independent propulsion and advanced combat and communications systems.[21]

In December 2007 the Australian Government authorised the Navy to begin planning for the Collins class' replacement. The Navy will research options for the submarines and will report back to the government in 2011. The contract for the new boats is planned to be signed in 2014 or 2015 with the first new submarine entering service in 2025. It is expected that the submarines will be built by ASC in Adelaide.[22]


Australian sailors who qualify as submariners are awarded a badge depicting two dolphins and a crown. This badge (known as a sailor's 'dolphins') was introduced in 1964 or 1965 and was adopted by the Royal Navy Submarine Service in 1972.[23][24]
