How American, British, and French subs stack up

Australia’s abrupt decision to scrap a deal with France for conventional submarines to pursue nuclear-powered subs with the US and UK has stirred up geopolitical tensions by infuriating France.

Australia wants to replace its Collins-class attack submarines. The plan was initially to purchase a dozen diesel-electric Shortfin Barracuda submarines from France, but Australia has since abandoned that plan and partnered with the US and UK to acquire nuclear submarine technology.

At this time, it is unclear whether Australia will pursue British or American submarine technology or some mixture of the two, but here is how American, British, and French submarine technology compares.
