ASC Shipbuilding

ASC was responsible for building Australia’s fleet of Collins class submarines in Adelaide in the 1990s and now provides design enhancements, maintenance and through-life support of the six-vessel fleet at the Osborne Naval Shipyard.

A workforce of about 1000 designers, engineers and tradespeople support the fleet in South Australia and Western Australia, and will continue until the end of its operational life. This support involves full-cycle dockings, as well as design enhancements to ensure the fleet remains at the cutting edge of submarine technology.

A full-cycle docking is an extensive maintenance and upgrade refit program, typically involving thousands of tasks over two years, in which each submarine rotates through after a decade of operational service. The Collins class submarine fleet will have its service life extended to ensure capability is maintained until the Attack class submarines are introduced into service in the early 2030s.
