PMB Defence (PMB) is a leading supplier of high quality energy and specialised engineering solutions for submarine platforms. Formed in 1989, PMB Defence (formerly Pacific Marine Batteries) began with a sole focus on producing the Main Storage Battery for the COLLINS Class of submarines. Since 1989 PMB has continuously supplied Main Storage Batteries for the COLLINS Class, whilst growing an in-country engineering capability. This has progressively evolved to be a dependable supplier of engineering services, battery and niche product solutions for both current and future submarine capabilities. Our state-of-the art production, research and development and engineering facilities are situated at the heart of the Techport (Naval Industry Hub) opposite ASC, the builder of Australia’s COLLINS Class submarines, and Air Warfare Destroyers.
