With the first of the new Attack-class attack submarines starting delivery only by 2032, the Royal Australian Navy (RAN) is considering the upgrading and life extension of its existing fleet of Collins-class submarines and allow them to operate until the replacements are ready.

This was announced by the RAN Chief Vice Admiral Mike Noonan as he faced the Senate.

Originally the Collins-class were scheduled to retire by 2026, which is now not acceptable as it would render the RAN without a submarine until the first Attack-class comes into service.

No full details nor the exact number of submarines to receive the upgrade are available yet, although it is estimated to be between three to six of the submarines.

French shipbuilder Naval Group was awarded the contract to supply and build 12 new submarines based on their Shortfin Barracuda design. The first submarine is scheduled for delivery by 2032, with succeeding submarines of the class delivered every two years.

It is also estimated that it would take at least 3 years for the RAN to conduct tests and evaluation of the submarines before they are commissioned into service, which means the first submarine may only enter service by around 2035.
