Superior Battery Systems for World Class Submariners


Established in 1989, PMB Defence is a world leading manufacturer of submarine battery systems.  PMB Defence (PMB) began life with a sole focus on producing the highest quality Main Storage Batteries for the COLLINS Class of submarines.

Assisted by our privileged access to Australian stakeholders we have evolved into a leading supplier of high-quality energy and specialised engineering solutions in Australia and select international markets, PMB Defence has now grown its business by winning various local and international contracts (supplying both traditional as well as new technology submarine battery systems) to Australia, Canada, the United Kingdom and other international customers by specialising in lead acid, nickel zinc and lithium battery system solutions.

We know that deep below the surface, just minutes of additional battery life can be the difference between mission success and failure. That’s why we design and build our submarine battery systems to the highest possible standard.  Understanding the submarine domain and our customer needs through close collaboration is key to our success.

In 2022, PMB Defence was awarded SME of the year at the Australian Defence Industry Awards, making now a great time to join the team!

Our purpose-built production, R&D and Engineering facilities are located at the heart of the naval shipbuilding in Australia.  These new facilities represent a significant investment in submarine battery capability and capacity that will enable the next generation of systems to provide superior results for our customers.
