Attack Class submarine
Flag The Attack Class diesel-electric submarine will replace the Collins Class in service with the Australian Navy with the first boat, HMAS Attack, to be delivered in the 2030s. The design is a variant of the French Shortfin Barracuda Block 1A from Naval Group which is a conventionally-powered variant of the French Navy’s Suffren Class (aka Barracuda Class) nuclear powered attack submarine. The program is being managed in Australia as the Future Submarine program. Twelve boats are planned which is double the number of Collins-class boats already in RAN service.

The boat promises high levels of stealth and the sonar suite, supplied by Thales, is considered the best available for a boat of this displacement. The coupling of excellent acoustic discretion, state-of-the-art detection and tracking capabilities, and future technological growth that will give the RAN the capacity to remain far ahead of any regional adversary well into the 2060’s.

The choice of a traditional diesel-electric power plan instead of Air Independent Power (AIP) reflects the long-distance operating pattern required by Australian submarine forces. There are also persistent rumors that the SSN-derived boat gives Australia the option of making some of the class nuclear-powered, which would be a capability leap for the Australia Navy but might be politically sensitive.
