We see so many pics of Virgina Class but hardly any of the Sea Wolf
Sea Wolf is a top tier SSN capabilitys almost unknown
Right now, there are eleven Virginia Class boats launched and in the water. The latest, the USS North Dakota, SSN-784, was christened in November 2013.
Only three Sea Wolves were built, and one of those, USS Jimmy Carter, SSN-23, is very secretive and used almost exclusively for very stealthy, special operations missions. USS Sea Wolf, SSN-21 and USS Conecticut, SSN-22, both displace 9,300 tons, have eight 650mm tubes and carry 50 weapons each. They were commissioned in 1997 and 1998 and are still just as quiet and deadly as anything else in the water.
The Jimmy Carter was lengthened by 100 feet and so is over 450 feet long and displaces over 12,000 tons. She has the same number and size of tubes and weapons, but she had a Multi-Mission Platform (MMP) section added to her which lets her do a number of "special" things like launch and recover special ROVs, Navy SEAL forces, and also be used as an underwater splicing chamber for tapping undersea fiber optic cables. Like I said...very special and highly secretive missions. BTW, that extra section of the Jimmy Carter almost cost a billion dollars to add itself! Because of that extra build, she did not commission until 2005, actually after the USS Virginia had commissioned.
By comparison, the Virginia class were designed to be just as as stealthy, but smaller (7,800 tons) and less heavily armed (four 533mm tubes and 27 weapons + 12 missiles) sisters of the Sea Wolf class. The Sea Wolf was cancelled because it was felt the US Navy did not need 30-40 of those bigger boats (and they planned to buildthat many of them to begin with) when 30-40 of the smaller ones would serve just as well in the post cold war world.
So here come the Virginias, and we now have 11 of them in the water.
