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

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

With a history of innovation and collaboration, ASC has played a pivotal role in growing Australia’s defence industry and strengthening the nation’s naval capabilities.

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, excellence and security of supply. ASC is committed to maximising Australian industry involvement in its programs.

ASC is preparing to deliver the Collins Class Submarine’s Life of Type Extension (LOTE). This upgrade will continue the evolution of the fleet and maintain Australia’s world-class submarine capability into the 2040s. The program will integrate leading international technology while maximising Australian industry participation.

ASC is always searching for new Australian supply chain partners, including small to medium enterprises, to continue its delivery of world-class submarine performance. ASC is committed to a sovereign supply chain capability and to partnering with Overseas Equipment Manufacturers to achieve this.

Suppliers interested in participating in programs at ASC are requested to respond to the ASC Expressions of Interest on the ICN portal.

As ASC seeks to engage with industry on specific work requirements, suppliers with compatible capabilities will be contacted.
