The Skate became the 3rd Nuclear Submarine for the US Navy and the first class to go into a series production. There were 4 vessels in the class, the lead ship being the Skate. The 3 that followed were the Seadragon, Sargo and Swordfish.
The Skate class were small boats compared to their predecessors, only 268 feet long, with a maximum beam of 25 feet and a submerged displacement of 2848 tons.
Originally designed and built for under ice exploration, these submarines pioneered techniques for use in and around the ice packs of the North Pole.
