Skate-class Nuclear Attack Submarine

The Skate-class submarines were the United States Navy's first production run of nuclear-powered submarines. They were an evolution of the Tang-class in everything except their propulsion plants, which were based on the operational prototype USS Nautilus. The four Skate-class boats re-introduced stern torpedo tubes. Although among the smallest nuclear-powered attack submarines ever built, the Skate-class served for many years, with the last being decommissioned in 1989. USS Skate was the first submarine to surface at the North Pole, on March 17^th 1959.

Skate and Sargo were built with the S3W reactor, Swordfish and Seadragon also had the S3W reactor in the S4W reactor plant (same machinery in an alternate arrangement).
