DEFENCE CONNECT: Government commits $200m to expand Collins torpedo stocks – 21 March 2025

The government has announced a major enhancement to the Royal Australian Navy’s submarine capabilities, committing $200 million to acquire additional MK-48 heavyweight torpedoes from the United States. The acquisition will significantly strengthen both the defensive and offensive capabilities of Australia’s Collins Class submarines, as well as its future nuclear-powered fleet. The MK-48 torpedoes are designed for both anti-submarine and anti-surface warfare, ensuring the RAN maintains a cutting-edge deterrence capability in an increasingly complex security environment.

Minister for Defence Industry and Capability Delivery Pat Conroy stated, “This boost to our stocks of MK-48 heavyweight torpedoes demonstrates the government’s commitment to delivering on priorities in the 2024 National Defence Strategy that contribute to the strategy of denial.” The MK-48 torpedo is developed as part of a long-standing joint program between Australia and the United States. This collaboration ensures ongoing advancements in both hardware and software, enhancing the effectiveness of the weapon against evolving threats. The partnership also underscores the deep defence ties between the two nations, with shared expertise contributing to the sustainment and modernisation of this critical capability. It also marks another milestone in the government’s efforts to implement the 2024 National Defence Strategy, which emphasises resilience, regional security and cutting-edge defence technology.

A key aspect of the program is the assembly and testing of the torpedoes in Australia. The Torpedo Maintenance Facility in Western Australia is certified to assemble, maintain and test the MK-48 for use in both the Royal Australian Navy and the United States Navy. This facility plays a crucial role in maintaining operational readiness and ensuring the latest technological advancements are incorporated into the weapons system.
