ASC
ASC Pty Ltd, formerly known as the Australian Submarine Corporation, is the cornerstone of Australia’s sovereign submarine capability. Headquartered in Osborne, South Australia, ASC has played a central role in naval shipbuilding and submarine sustainment for over three decades. As the builder and now the in-service support provider of the Collins Class submarines, ASC ensures the Royal Australian Navy’s underwater fleet remains capable, advanced, and ready for modern defense demands.
With more than 1,800 skilled personnel across its South Australia and Western Australia facilities, ASC operates at the forefront of high-precision engineering, naval logistics, and through-life asset management. The company delivers deep maintenance, upgrades, and life-extension services for the Collins Class fleet, applying world-class engineering solutions, performance management systems, and safety protocols.
ASC’s reputation has been built on its proven capability to manage complex submarine platforms. Through its Collins Class sustainment work, this brand has achieved some of the highest levels of submarine availability and performance globally – ensuring that Australia’s six submarines maintain their operational readiness and technological edge. The company works closely with the Royal Australian Navy, Defence Science and Technology Group (DSTG), and international partners to deliver innovations that extend platform life and increase fleet capability.
Looking to the future, ASC is preparing for a pivotal role in Australia’s next-generation submarine program. As part of the trilateral AUKUS security partnership, Australia is set to acquire conventionally armed, nuclear-powered submarines, and ASC is expected to play a significant role in their local construction, integration, and sustainment. This strategic direction marks a generational leap in capability and further cements ASC’s role as Australia’s sovereign submarine partner.
In addition to its submarine work, the company supports Australia’s broader naval capability, including workforce training, systems integration, and technology development. Its apprentice and graduate programs are considered among the best in the defense industry, helping nurture Australia’s future engineers, technicians, and defense leaders.

ASC’s commitment to safety, performance excellence, and sovereign capability is underscored by its strong partnerships across government, industry, and academia. The company’s facilities feature advanced infrastructure, digital engineering platforms, and deep test and evaluation capabilities tailored for submarine environments.
With over 30 years of experience, ASC is more than a defense contractor – it is a vital part of Australia’s defense readiness and maritime security. Whether delivering maintenance to existing submarines or preparing for future underwater platforms, ASC is proudly building and sustaining Australia’s naval future.
