Boeing also developed hydrofoils in the 1960s. The screw-driven USS High Point (PCH-1) was an experimental submarine hunter. The patrol hydrofoil USS Tucumcari (PGH-2) was more successful. Only one was built, but it saw service in Vietnam and Europe before running aground in 1972. Its waterjet and fully submersed flying foils were the example for the later Pegasus-class patrol hydrofoils and the Model 929 Jetfoil ferries in the 1980s. The Tucumcari and later boats were produced in Renton. While the Navy hydrofoils were withdrawn from service in the late 1980s, the Boeing Jetfoils are still in service in Asia.
