Australian firm PMB Defence Engineering has entered into a significant partnership with BAE Systems, focusing on the potential integration of its advanced nickel-zinc battery systems into the design of next-generation nuclear-powered submarines under the AUKUS pact. This landmark contract is valued at over 34 million Australian dollars, equating to approximately 22.1 million US dollars, and provides BAE Systems with essential technical data to evaluate the compatibility of PMB’s battery systems within submarine designs.
The nickel-zinc batteries, known for their high energy density, offer approximately double the energy capacity of traditional lead-acid batteries commonly employed in submarine operations. This enhancement is crucial, as these batteries are not only used to power various submarine systems but also serve as valuable backup energy sources.
Should the evaluation prove successful, PMB will initiate the manufacturing of these innovative batteries at its facility in Osborne, South Australia. This collaboration builds upon an existing relationship between PMB, the UK Ministry of Defence, and the Submarine Delivery Agency, which have been actively testing similar technologies for the Royal Navy’s Astute-class submarines.
In addition to this cutting-edge project, PMB Defence Engineering will draw from its extensive experience supporting the power supply systems for the Royal Australian Navy’s Collins-class submarines, which have been in operation since the 1990s.
The emphasis on industrial collaboration is integral to the AUKUS submarine initiative, which showcases a collective effort involving advanced nuclear designs from the UK, Australia, and the US. In 2024, BAE Systems, along with ASC, was designated as Australia’s sovereign shipbuilding partners under this ambitious project, with construction activities slated to occur primarily at Osborne in Adelaide and other locations across Australia.
Craig Lockhart, CEO of BAE Systems Australia, highlighted the importance of this collaboration, noting that it exemplifies the ongoing commitment to enhance Australia’s participation in the trilateral submarine program. He stated, “Strong progress is being made on the detailed design phase of the SSN-AUKUS program; the workforce continues to grow, and strong collaboration is occurring between submarine build partners, the UK and Australian governments, and industry.”
Lockhart affirmed BAE Systems’ dedication to working closely with Australian companies like PMB to identify and seize opportunities for their involvement in the design and construction phases of the SSN-AUKUS submarines, further solidifying the international partnership aimed at reinforcing security and defense capabilities in the region.
