Collins Class Submarines

The RAN operates six Collins Class submarines which entered service between July 1996 and July 1999. Based at Fleet Base West in Western Australia, they are a formidable element in Australia's defence capability.

Collins Class submarines are tailored specifically for their defence and two-ocean surveillance role in the Royal Australian Navy. The Swedish signed submarines built in Australia are as quiet as advanced technology can achieve.

Collins Class submarines move silently on electric power supplied by banks of new-technology batteries charged by three on-board diesel generator sets.
