$11b upgrades to Australia's existing submarines scaled back
Australia is scaling back its planned upgrades to the Collins Class submarines, which were intended to extend their operational life by a decade. The federal government has decided not to replace the diesel engines and generators unless absolutely necessary, opting instead for individual assessments of each submarine. The $11 billion investment aims to keep the submarines operational into the 2040s, bridging the gap until nuclear-powered submarines are introduced.
- ▪The upgrades to the Collins Class submarines will not include replacing their diesel engines and generators unless deemed necessary.
- ▪The first submarine to undergo the life extension process will be HMAS Farncomb, which is 28 years old.
- ▪The government argues that the original upgrade plan was underfunded and closely tied to a previously abandoned deal for French submarines.
