USS SIMPSON (FFG 56) is a single screw, gas turbine powered, guided missile frigate (FFG) of the Oliver Hazard Perry class. The main propulsion system includes two General Electric LM2500 gas turbines driving a single controllable pitch propeller through a conventional main reduction gear, shaft and clutch.
The ship’s integrated combat system automates the interactions of sensors, tactical data process and display, and weapons so that reaction time is reduced to a minimum. The combat system includes an automatic digital data link which permits internship computer communication on a near real time basis. Digital computers also provide rapid evaluation of potential threats detected by the radars, sonar and other sensors. Should the need arise, rapid fire guns, anti-submarine torpedoes, or an embarked Light Airborne Multipurpose ASW System (LAMPS) helicopters can be employed to counter air, surface and subsurface threats.
