Contract Extensions for Collins Class Submarines
8 AUGUST 2025
Defence has extended two contracts for the sustainment of the sonars and periscopes for the Collins class submarines.
Thales Australia has been awarded a five-year extension valued at $178 million; and BAE Systems Australia a five-year extension at a cost of $89 million.
These contracts will provide ongoing support for the Collins class submarines’ sonars and periscopes through to the 2030s.
These extensions reflect the Government’s $4 to $5 billion commitment to ensuring the Collins class submarines remain an enduring, potent and credible submarine capability critical to Australia’s national security.
This demonstrates the Government’s commitment to investing in Australian industry and workers, supporting a local Australian workforce to sustain Australia’s sovereign capabilities.
These contract extensions will directly support job security for over 100 highly skilled workers.
