But getting the design parameters right is critical for a deliverable project, and it’s worth understanding the key issues, even if that requires some ‘techie talk’. They include 14 Ohio-class ballistic-missile submarines, or “boomers,” which the Navy expects to begin replacing with 12 new Columbia-class boomers starting in 2021. [42] Despite ongoing support for the submarines to be built in South Australia by successive Coalition and Labor governments, in July 2014, the Abbott-led Coalition government abandoned their pre-election commitment to ASC-based construction and opened up the likely possibility of building the submarines at a foreign shipyard. Italy’s Near Future Submarine (NFS) design will be Italian in nature.
In the early phases of the replacement project, four design options were identified: purchase a Military-Off-The-Shelf (MOTS) design, modify a MOTS design for Australian conditions, design an evolution of the Collins-class, or create a new design.
[31] On 20 February 2015 the Australian Government publicly announced three key strategic considerations that would be taken into account in the competitive evaluation process, these being: that the future submarines would have a similar range and endurance to the Collins class, superior sensor performance and stealth compared to the Collins class, and that the combat system and Mark 48 Mod 7 torpedo jointly developed between the United States and Australia would be the future submarines' preferred combat system and main weapon. [4] In February 2015 the Australian Government identified its preference for the future submarines to have a US weapon system and heavyweight torpedo. The 2009 Defence White Paper identified a land strike capability as an important addition to torpedo, mine and anti-ship missile weapons. [21], A September 2012 weapons technology swap deal and a July 2014 agreement on the sharing of defence technology were seen as preliminary steps towards Australian-Japanese collaboration on a submarine design, or towards integrating technologies like the Sōryū's Kockums designed air-independent propulsion Stirling engines and research into incorporating the Japanese boats' hydrodynamic capabilities into a potential SEA 1000 design.
Detailed Collins specifications are classified, but missions can last 60 days or more. The Attack-class submarine is a future class of submarines for the Royal Australian Navy based on the Shortfin Barracuda proposal by French shipbuilder Naval Group (formerly known as DCNS) to replace the Collins-class submarines. Instead of upgrading the Virginia, the sailing branch anticipates designing a brand-new attack boat it calls the SSN(X). The U.S. Navy plans to develop two new classes of submarine, according to congressional analysis of the sea service’s shipbuilding plan for 2019. Naval Group (formerly DCNS) was announced as Australia’s International partner for the design and build of 12 Future Submarines in 2016. Sustainment will continue into the 2080s.
