Royal Australian Navy Submarine Service

The Royal Australian Navy Submarine Service is 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 Submarines is Commodore T.A. Brown, RAN.

History

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

1914 to 1945

After the formation of the 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.Whitley 2000, p. 17. Initially, it had been intended to purchase three small submarines, but this order was later changed,Gillett & Graham 1977, p. 193. 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 with the cause unknown. Its whereabouts was a mystery until it was located by searchers southeast of the Duke of York Islands on 20 December 2017.

''AE2'' remained in the South Pacific until December 1914, when she was ordered to the Mediterranean to support the British-led operations off the Gallipoli peninsula in Turkey. ''AE2'' was the first Empire submarine to penetrate the Dardanelles, achieving this task on 25 April 1915 (the day of the first landings at Gallipoli). ''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.

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 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 British O Class submarines and 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.

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.

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.Cooper, in ''The Royal Australian Navy'', p. 194 The final Royal Navy submarine to be based in Australia, HMS ''Trump'', was withdrawn in 1969.

The first Australian ''Oberon'' class submarine, , 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 , on Sydney Harbor. The ''Oberon''s 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. 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. The ''Oberon'' class regularly conducted exercises with the Special Air Service Regiment (SAS) and to a lesser extent the 1st Commando Regiment and the Clearance Diving Branch.Patrick 2014, p. 37. In 1980, the SAS was tasked to develop a maritime counter terrorist capability together with the clearance divers and conducted the first ever swimmer release from a submerged Australian submarine. ''Onslow'' was fitted with a four-man diving chamber for exit and reentry of SAS swimmers.Shaw, ''HMAS Onslow'', p. 10 As part of the Government's Two Ocean Navy policy submarines were homeported at HMAS ''Stirling'' in Western 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 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 supported these trials between 1992 and 1998. Tests conducted on 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. The second boat commissioned was ''Farncomb'' (1998) followed by ''Waller'' (1999), ''Dechaineux'' (2001), ''Sheean'' (2001) and ''Rankin'' (2003). The ''Collins'' class submarines currently rank among the most effective conventional submarines in the world.

Like the ''Oberon'' class, the ''Collins''-class submarines have conducted surveillance patrols. In 1999, it was reported that ''Waller'' and a second boat operated in support of the International Force for East Timor (INTERFET) providing escorts for transport ships, monitoring Indonesian communications, inserting special forces and had been collecting intelligence on East Timor for months.Hyland, ''Arms race' leaving our subs all at sea'' A submarine, possibly ''Waller'', reportedly inserted Navy clearance divers into the Oecussi Enclave to conduct a covert beach reconnaissance ahead of an amphibious landing on 22 October 1999. Two boats ''Collins'' and ''Dechaineux'' received the special forces upgrade providing the capability whilst submerged to release several swimmers and for their reentry, filling a capability gap the former ''Oberon''-class boat ''Onslow'' had provided.Australian National Audit Office, "2014–15 major projects report : Department of Defence" While the Collins class submarines' performance has improved over time, their maximum diving depth was permanently reduced following the near-loss of ''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 on board submarines. The first female submariners began their training at the Submarine Training and Systems Centre in June 1998.

Today

The Royal Australian Navy Submarine Force Element Group Headquarters, and all six of the ''Collins'' Class submarines, are at HMAS ''Stirling'' located on Garden Island, near Perth. 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.

Under current Royal Australian Navy doctrine, the Submarine Service has the following responsibilities:
*intelligence collection and surveillance;
*maritime strike and interdiction;
*barrier operations;
*advanced force operations;
*layered defense;
*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 authorized 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.

Future submarines

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

In September 2013, Rear Admiral Greg Sammut AO was appointed as Head Future Submarine Program.Rear Admiral Gregory Sammut

In 2016, France won a contract to build a conventionally-powered variant of its Barracuda-class submarine for Australia.

In September 2021, it was announced that the deal with France had been scrapped, and Australia would be working with the United States and United Kingdom to build and operate at least 8 nuclear fast-attack submarines as part of the new AUKUS agreement.

Dolphin badge

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 designed by Commander Alan McIntosh RAN, and was introduced in 1966; a similar badge was adopted by the Royal Navy Submarine Service in 1972.Seal 2013, pp. 4–5.
