Commissioned in 2005, the nuclear-powered fast-attack submarine USS Jimmy Carter (SSN-23) is one of the most remarkable vessels ever to sail the seas. This Seawolf-class marvel is no ordinary submarine. It hums with unmatched speed, stealth, and weaponry even compared to more modern boats. It is also the most expensive SSN submarine the US Navy has ever built, costing over $3.5 billion two decades ago. Like a character in a superhero comic, this is a unique super-sub that underwent classified modifications by the military, producing enhanced physical capabilities that sets it apart from all other submarines.
Its amazing capabilities has earned its crew the Navy's highest honor: the Presidential Unit Citation for "extraordinary heroism in action against an enemy."
