Spruance-class Destroyer

The Spruance-class destroyer were a class of multirole destroyer was developed by the United States to replace a large number of World War II-built Allen M. Sumner and Gearing-class destroyers, and was the primary destroyer built for the U.S. Navy during the 1970s. Both the Kidd and Ticonderoga-class ships are based on the Spruance-class design. Serving for three decades, the Spruance-class was designed to escort a carrier group with a primary ASW mission. First commissioned in 1975, the class was designed with gas-turbine propulsion, all-digital weapons systems, automated 5-inch guns and Tomahawk cruise missiles. Rather than extend the life of the class, the Navy opted to accelerate its retirement. The last ship of the class was decommissioned in 2005, with most examples broken up or destroyed as targets. A few nations including Australia and Mexico have license built their own Spruance-class destroyers.
