PHM Pegasus is a ship simulation and action game released for the Commodore 64, Apple II, Amstrad CPC, and ZX Spectrum. The title refers to the USS Pegasus (PHM-1), one of the Pegasus-class hydrofoils which were used by the U.S. Navy in the 1970s.
The game was developed by Lucasfilm Games and published by Electronic Arts. The game has eight different missions in which players must maneuver helicopters, convoy ships, and patrol hydrofoil missilecrafts to survey areas, clear areas of enemy ships, and escort friendly ships.
Mission locations include the Persian Gulf, the Eastern Mediterranean, the Caribbean, and the Gulf of Sidra. The developers of the game consulted with Boeing Marine Systems, a manufacturer of hydrofoils, to increase the realism of the simulation.
