PHM 1 Pegasus

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 operate from Key West. They were the Navy's fastest ships when foilborne and driven by their single gas turbine. They had good range on their diesels, excellent seakeeping qualities, amazingly fast response to requirements for speed, and a potent punch. Since becoming operational, they established an unusually high availability rate while participating in a variety of missions, including significant involvement in the national drug interdiction program.
