George Washington class submarineとは 意味・読み方・使い方

The George Washington class was a class of nuclear-powered ballistic missile submarines employed by the United States Navy. The Navy ordered a class of nuclear-powered submarines armed with long-range strategic missiles on 31 December 1957, and tasked Electric Boat with converting two existing attack submarine hulls to ballistic missile-carrying boats to quickly create the deterrent force. To accomplish this conversion, Electric Boat persuaded the Navy in January 1958 to slip the launch dates for two Skipjack-class fast attack submarines, the just-begun Scorpion (SSN-589) and the not-yet-started Sculpin (SSN-590). On 12 February 1958, President of the United States Dwight D. Eisenhower signed funding for three ballistic missile submarines.
