Forbes: Sweden’s Famously Stealthy Submarine Is Now Even Quieter

When Sweden loaned one of its AIP (Air Independent Power) submarines to the U.S. Navy, it made waves. HMS Gotland operated out of San Diego for over 2 years in the late 2000s, reputably ‘sinking’ the carrier USS Ronald Reagan (CVN-76) in an exercise. It wasn’t fast, but it was quiet, which is a valuable quality in underwater warfare. Now that submarine has been upgraded with an even stealthier propulsion system.

A cornerstone of Gotland's effectiveness in exercises with the U.S. Navy was its AIP propulsion. Indeed it was a major factor in why the Navy wanted to exercise against this specific boat. AIP meant that it could stay submerged for much longer than other non-nuclear boats.

Today the AIP is a generation newer than when the U.S. Navy faced her. Gotland was upgraded by Saab in 2018 and a second of the class, HMS Uppland, is nearly ready for delivery.

WNU Editor:  It should also be mentioned that this sub does not run on nuclear power.

Love the swedes
Plus. They'll be on our side if China tries anything. They can prepare against a couple nations but not against the entire world. Or even NATO for that manner. .Japan would also join in. India would join in. No way China could win. Against the US they could win at home/in the western Pacific. But not against the alliance. No chance in hell

Where one of the biggest (if not the biggest) constraints is budget, opting for nuclear limits the number of hulls/platforms you can afford to procure and/or operate.

Fewer hulls means that loss of even 1 his felt far more. The US should have a mix.

It will all be moot when robots are thrown in the mix. No one will be arguing. They will just be doing.
