ASC Pty Ltd has proudly served as Australia’s sovereign submarine builder and sustainer for over 35 years. ASC built the Collins Class submarines (CCSMs) and now sustains the fleet at its facilities in Osborne, South Australia and Henderson, Western Australia.

Supported by its predominantly Australian supply chain and a highly skilled workforce, the company delivers world-class submarine performance to meet the Royal Australian Navy’s (RAN’s) operational requirements.

ASC employs more than 1,600 skilled personnel who provide submarine sustainment, upgrade and life of type extension services to the RAN.

ASC is known for its supply chain excellence. A robust supply chain incorporating high levels of Australian industry capability and participation is central to ensuring reliability and security of supply. The CCSM Program delivers more than 90 per cent Australian Industry Content, creating jobs and economic growth for the nation. ASC’s annual Australian spend is valued at more than $200 million.

ASC is preparing to deliver the CCSM Life of Type Extension (LOTE) Program. This will continue the evaluation of the fleet and extend the life of all six submarines into the 2040s. The LOTE will integrate leading international technology while maximising Australian industry participation.

A long standing partner of the Australian Department of Defence, ASC has provided training support to the RAN’s submariners for more than 25 years.

ASC is now partnering with the Australian Government to deliver the Sovereign Shipbuilding Talent Pool, which will help ensure the nation is ‘work ready’ for the nuclear-powered submarine program.
