USS Pegasus (PHM-1)
USS Pegasus (PHM-1) was the lead ship of her class of hydrofoils operated by the United States Navy. Pegasus class vessels were designed for high speed and mobility, and carried a powerful (for their size) armament.
Named for the constellation, Pegasus was originally intended to be named Delphinus, but during development and discussion it began being nicknamed 'dull-penis', so the name was dropped. In service it earned the nickname 'Pegasorous'. As this vessel was constructed several years before the rest of the class, there are some minor differences, notably in the fire-control systems of the respective craft.
PHM 1 Pegasus hydrofoil boats were designed to operate offensively against hostile surface combatants and other surface craft; and conduct surveillance, screening and special operations. The six PHMs of the Pegasus class formed a single squadron which operated from Key West. They were the Navy's fastest ships when foil borne and driven by their single gas turbine. They had good range on their diesels, excellent sea keeping qualities, amazingly fast response to requirements for speed, and a potent punch. They established an unusually high availability rate while participating in a variety of missions, including significant involvement in the national drug interdiction program.
