Design and Capabilities of the USS Plainview (AGEH-1)

The Genesis of Hydrofoil Innovation

The USS Plainview (AGEH-1) represented a significant technological leap in naval engineering, embodying the United States Navy’s quest for speed, agility, and tactical advantage on the high seas. Its construction began on May 8, 1964, with the Lockheed Shipbuilding and Construction Company at the helm, marking a bold venture into the development of hydrofoil ships.

Revolutionary Propulsion and Structure

Central to the Plainview’s design were its two General Electric LM1500 free-turbine turboshaft engines, adapted from the J79 turbojets that powered F-4 Phantom aircraft. This choice of propulsion enabled the Plainview to achieve remarkable speeds, making it the fastest ship of its kind during its operational period. The ship was capable of reaching speeds of 40 knots (74 km/h; 46 mph), a feat that was particularly impressive given its size and the technology of the time​​.

The hydrofoil system allowed the Plainview to ‘fly’ above the water surface at high speeds, minimizing hull resistance and maximizing efficiency. This system consisted of wing-like structures that could lift the vessel’s hull out of the water, dramatically reducing drag and enabling its high-speed capabilities. The design also featured a unique bridge, likened to an airplane cockpit due to its array of dials and gauges, underscoring the naval architects’ intention to blend aerodynamic principles with maritime engineering​​​​.
