In the early 1970s, gas turbine technology had reached the stage where it became feasible to consider marinization of state-of-the-art aircraft engines. Approximately concurrently with these technological advances, the U.S. Navy had the need to project replacements for many of its conventionally propelled surface ships of World War II vintage. Characteristics of good fuel economy coupled with potentially viable reliability and maintenance characteristics conditioned the development of main and auxiliary gas turbine prime movers for ships. Ship design, therefore, was strongly influenced by previously unavailable power plant characteristics. New ships are building and others actively being designed to draw upon these technological advantages, and a broad base of support is being established to ensure the continued long range mobility of the U.S. Navy’s ships.
