428-GX-USN 1131877:  USS Plainview (AGEH-1), the world’s largest hydrofoil vessel, lifts its hull from the waters of Puget Sound during tests by the builder, Lockheed Shipbuilding and Construction Company, Seattle, Washington.  When on foils, titanium propellers at the rear of the completely submerged foils powered by GE J-79 jet engines, drive the ship at speeds in excess of 40 knots.  A third foil at the stern serves as a rudder and stabilizer.  The vessel is a major item in the Navy’s broad investigation of hydrofoil vessels, 20 June 1968.
