23-571: The SSN-AUKUS , also known as the SSN-A , is a planned class of nuclear-powered fleet submarine ( SSN ) intended to enter service with the United Kingdom's Royal Navy in the late 2030s and Royal Australian Navy in the early 2040s. The class will replace the UK's Astute -class and Australia's Collins -class submarines. The UK commenced an Astute class replacement project in 2018, which

The ship building precinct includes a number of discrete facilities, as it has grown over the time it has existed. The Government of South Australia built a "common user facility" that includes a wharf and Shiplift constructed between 2007 and 2010, known as Techport Australia . It was designed by Aurecon and constructed by McConnell Dowell and Built Environs . Techport

It is the most advanced shipbuilding facility in both Australia and the Southern Hemisphere . The facility has produced a range of major surface combatants and submerged vessels such as Destroyers , Frigates , Patrol boats and Submarines for the Royal Australian Navy fleet . The facility
115-401: Is described as being "the next step in developing autonomous underwater warfare capability" and is also to feed into the design of SSNR. In January 2023, it was reported that the submarines were likely to incorporate a vertical launch system (VLS) for land-attack missiles. This would be a first for Royal Navy SSNs, which currently launch land-attack missiles via their torpedo tubes. A VLS system
138-862: The Attack -class submarines . Instead signing a monumental agreement with the United Kingdom and the United States to build 8 SSN-AUKUS submarines at the Osborne Naval Shipyard Adelaide for the Royal Australian Navy . The first submarine is expected in the early 2030s. November 2023 the Australian government performed a land swap with the state government, trading land on three nearby military sites for 60 acres of land around Osborne Naval Shipyard for
161-541: The Collins class, and BAE Systems . The building of the first boat is to begin by the end of the 2030s with the boat delivered in the early 2040s. A boat will be built every three years. Australia will operate two submarine classes, and if the build schedule for the SSN-AUKUS falls behind, has the option of purchasing up to two additional Virginia class boats from the United States. As a non-nuclear weapon state under
184-599: The IAEA , Australia will not produce nuclear fuel for its SSNs. The UK and US intend to provide Australia with nuclear material in complete, welded nuclear power units. In March 2023, Vice Admiral Jonathan Mead , head of the Australian Nuclear Powered Submarine Task Force, said the SSN-AUKUS design was "about 70 per cent mature". The SSN-AUKUS class "will incorporate US technology such as propulsion plant systems and components,
207-658: The United States . The class will be powered by Rolls-Royce's pressurised water reactors (PWR). The submarines will displace over 10,000 tonnes. The United Kingdom began planning for the replacement of the Astute class of submarines in early 2018. Initially, the programme was known as the Maritime Underwater Future Capability (MUFC). The concept phase was scheduled to last for three years to assess requirements and consider options but

253-463: The UK Ministry of Defence, the site will double in size creating a further 1170 jobs needed to support the delivery of the Australian boats. In October 2023, the UK government announced a series of contracts with BAE Systems, Rolls-Royce and Babcock, collectively worth £4 billion, to support the design and development of the submarine class up to 2028. These contracts will fund the finalization of
SECTION 10
#1732780307151276-640: The UK would boost defense spending by additional £5 billion over two years, some of which would go towards funding "the next phase of the AUKUS submarine programme." The first SSN-AUKUS class boat for the Royal Navy will commence construction in Barrow in Furness as early as the late 2020s and is expected to be operational as early as the late 2030s. The Royal Navy boats will be built by BAE Systems . As of 2023,
299-427: The facility are under construction to triple the size of the shipyard to accommodate SSN-AUKUS submarine construction. Once completed, the facility will be one of only a handful across the world which will have the capacity to produce large surface combatant vessels and nuclear-powered submarines simultaneously. According to preliminary plans for the new shipyard, Osborne will receive a third shiplift and potentially
322-477: The government in the form of two £85 million contracts to BAE Systems and Rolls-Royce Holdings for early design work on the SSNR. The investment will support 350 jobs for the UK economy. In November 2022, MSubs Ltd was awarded a £15.4m contract to build an XLUUV (Extra Large Uncrewed Underwater Vehicle) vessel which is to be delivered to the Royal Navy within two years. The 17-tonne vessel (known as Project CETUS )

The Royal Australian Navy will acquire five SSN-AUKUS class boats that will be built at the Osborne Naval Shipyard in South Australia . A new submarine construction yard will be constructed at Osborne to be known as the Submarine Construction Yard. The Royal Australian Navy boats will be built by a joint venture between ASC , who constructed and maintain
368-547: The workforce at Barrow in Furness was being expanded from 10,000 to 17,000 to support both the Dreadnought class program and the SSN-AUKUS class. The SSN-AUKUS class will be powered by a Rolls-Royce pressurised water reactor (PWR) , manufactured at an expanded Rolls Royce Raynesway site in Derby . Australia is to invest A$ 4.6 billion (£2.4 billion) to allow the expansion of Rolls Royce's Derby site, and alongside funding from

The shipyard will notably be constructing SSN-AUKUS submarines from 2030s onwards, as the primary manufacturing hub of the trilateral AUKUS announcement in 2021. The facility currently administers Collins-class submarine full-cycle docking and 'Life of Type' extension program, as well as the Hunter-class frigate program and Arafura-class offshore patrol vessels . As of 2024, significant expansions of

The largest building in the new complex is known as Building 22, and is 80 metres (260 ft) high with a footprint of 170 by 50 metres (560 ft × 160 ft), large enough for assembly of two frigates other than the upper superstructure. In September 2021, the Morrison government scrapped the French multi-billion-dollar deal to build
437-674: Was described as likely to increase interoperability options with the US Navy since future US land attack missiles may not have a horizontal launch option. Following an 18-month consultation starting in September 2021, the design was renamed SSN-AUKUS in March 2023 when Australia joined the programme and additional US technology was incorporated, both as part of the AUKUS agreement. The British Prime Minister Rishi Sunak announced in March 2023 that

The ongoing SSNR design was renamed SSN-AUKUS in March 2023, under the 2021 AUKUS trilateral security partnership, when Australia joined the programme and additional US technology was incorporated into the design. Australia plans to build five SSN-AUKUS submarines in addition to acquiring three nuclear-powered Virginia -class submarines from

The shiplift was supplied by Rolls-Royce and is 156 metres (512 ft) long and 34 metres (112 ft) wide. It can lift 9,300 tonnes (9,200 long tons; 10,300 short tons) from a water depth of 18 metres (59 ft). It is designed to allow for future expansion to 210 metres (690 ft) length and lifting capacity of 20,000 tonnes (20,000 long tons; 22,000 short tons). Between 2017 and 2020, an extension

In 2020, the Ministry of Defence recruited for a Submarine Delivery Agency Project Manager to work on the SSNR design and development process. In March 2021, the government's defence paper Defence in a Competitive Age committed to funding the SSNR project. This was followed in September 2021 by an investment of £170 million by
