Fletcher-class destroyer

Fletcher-class destroyer. The Fletcher class was a class of 175 destroyers built for the United States Navy during World War II. They formed the backbone of the U.S. destroyer force through the Pacific War and the Korean War, renowned for their balance of firepower, speed, and durability. The class was named for Admiral Frank Friday Fletcher, a recipient of the Medal of Honor.

Design and development

The design originated from the General Board's 1939 requirements for a new fleet destroyer, seeking to improve upon the earlier Benson and Gleaves classes. Key designers at the Bureau of Construction and Repair and Bureau of Engineering prioritized a larger hull to accommodate a heavier main battery and enhanced anti-aircraft defense. The design featured a flush-deck hull and utilized high-pressure steam plants from Babcock & Wilcox boilers coupled with General Electric turbines. This project was accelerated following the outbreak of war in Europe and the attack on Pearl Harbor.

Service history

Fletcher-class destroyers entered service in 1942, with being the first commissioned. They served extensively in every major naval campaign of the Pacific Theater, including the Battle of Guadalcanal, the Battle of Leyte Gulf, and the Battle of Okinawa. They performed a wide array of duties, from escort and Anti-submarine warfare to shore bombardment and radar picket duties. Twenty-five were lost to enemy action, including the at the Battle off Samar. After World War II, many remained in service through the Korean War, with some transferred to allied navies like those of Japan, West Germany, and South Korea.

Ships in class

All 175 ships were built by several major shipyards: Bath Iron Works, Bethlehem Steel at Staten Island and San Francisco, Federal Shipbuilding and Drydock Company, Gulf Shipbuilding Corporation, and the Boston Navy Yard. The lead ship was , and the last completed was . Notable vessels included the , one of the most decorated U.S. destroyers of WWII, and the , named for the five Sullivan brothers. A significant number were modernized under programs like FRAM I during the Cold War to extend their service life.

Armament and modifications

As built, primary armament consisted of five single-mount 5"/38 caliber guns, controlled by the Mark 37 Gun Fire Control System with Mark 12 and Mark 22 radar. Anti-aircraft weaponry evolved rapidly; original 1.1"/75 caliber guns and .50 caliber machine guns were replaced by twin and quad mounts of Bofors 40 mm guns and Oerlikon 20 mm cannons. They carried ten 21-inch torpedo tubes for the Mark 15 torpedo. Post-war modifications under the Fleet Rehabilitation and Modernization program replaced torpedo tubes with Weapon Alpha anti-submarine rocket launchers and added Hedgehog projectors. Electronics were updated with modern AN/SPS-6 and AN/SPS-10 radar systems.

Legacy and preservation

The Fletcher class is considered one of the most successful and iconic destroyer designs in naval history, serving the United States Navy for nearly three decades and in other navies into the 21st century. Their design influenced subsequent classes like the Allen M. Sumner and Gearing classes. Four have been preserved as museum ships: at the Buffalo and Erie County Naval & Military Park, in Baton Rouge, Louisiana, at the Boston National Historical Park, and the former (now HS Velos) in Greece.
