ASC is Australia’s only established sovereign naval shipbuilding and submarine platform company.

With more than 1,300 employees at two facilities in South Australia and Western Australia, ASC has naval engineering, design, construction, maintenance and project management resources unparalleled within Australia’s defence industry.

ASC is responsible for submarine sustainment and the construction of major steel-hulled warships for the Royal Australian Navy (RAN).

ASC is committed to supporting the Australian Defence Force (ADF) by maintaining open lines of communication with its customer, understanding their expectations and priorities and striving to deliver the best possible results through an unwavering commitment to productivity and efficiency improvements.

ASC is a proprietary limited company registered under the Corporations Act 2001. ASC is wholly-owned by the Commonwealth, represented by the Minister for Finance (Shareholder Minister).

Initially established in 1985 at Osborne, South Australia, ASC was subsequently chosen in 1987 as the prime contractor for the design, manufacture and delivery of the RAN’s fleet of six Collins Class submarines (CCSM).

At the conclusion of the CCSM build program in 2003, ASC commenced a contract for the ongoing repair, maintenance and design upgrades of the submarines’ through-life support and is now performing at above international benchmarks for submarine availability, as part of the Australian Submarine Enterprise, which includes its partners the RAN and the Capability Acquisition and Sustainment Group (CASG).

ASC undertakes this work at the Osborne submarine deep maintenance facility in South Australia and at ASC West, in Henderson, Western Australia. ASC also provides submariner training services to the RAN at HMAS Stirling in Western Australia and is the largest industry provider of personnel into the Commonwealth’s Future Submarine program office.

In 2005, ASC was named as shipbuilder for the Hobart Class Air Warfare Destroyer (AWD) Alliance and subsequently signed the Alliance Based Target Incentive Agreement (ABTIA) in 2007. Since 2010, ASC and its AWD Alliance partners have been building and integrating the three AWDs at the Government’s shipbuilding facility at Osborne, South Australia. The first AWD, HMAS Hobart, was delivered in 2017, providing the RAN with its most advanced and complex warship.

The second AWD, HMAS Brisbane was commissioned into service in 2018 and the third, future destroyer Sydney, is due for its Provisional Acceptance in early 2020.

In 2017, ASC was named as the South Australian shipbuilder for the lead and second Arafura Class Offshore Patrol Vessels (OPV). ASC entered a contract with prime contractor and designer, Lürssen of Germany, for the construction of the vessels and achieved Keel Laying of the lead Arafura Class OPV, in May 2019.

In June 2018, ASC Shipbuilding was also announced as the shipbuilder of the Hunter Class Frigates, however following structural separation of ASC Shipbuilding from ASC in December 2018, ASC Shipbuilding became a subsidiary of BAE Systems Australia.

ASC retains responsibility for the delivery of the AWD and OPV Programs, utilising a contract workforce from ASC Shipbuilding.
