Description:
The SSN 21 Seawolf attack submarines were designed to be the quietest, fastest and most heavily armed vessels in the world. They can operate in any scenario against any threat, with mission and growth capabilities that far exceed Los Angeles-class submarines. They are enabled to successfully operate from underneath the Artic icepack to littoral environment. They perform attack, surveillance, intelligence, special warfare, cruise missile strike, mine warfare, anti-submarine (ASW) and anti-surface warfare (ASuW).
The SSN 21 Seawolf-class was planned for the the replacement of current Los Angeles-class submarines, but the US Navy discontinued the Seawolf-class due to its high acquisition costs ($2 billion per submarine) reducing the total number of submarines to be procured to only three.
The final Seawolf-class submarine, the SSN 23 USS Jimmy Carter, is an enlarged variant being modified to accommodate advanced technology for naval special warfare, tactical surveillance and mine warfare operations. The USS Jimmy Carter will be able to deploy and recover various payloads, undersea vehicles, without having to use torpedo tubes.
