Benson-class destroyer
The Benson class was a class of destroyers of the U.S. Navy built 1939–1943. The thirty 1,620-ton Benson-class destroyers were built in two groups. The first six were authorized in fiscal year 1938 (FY38) and laid down at Bethlehem Steel, Quincy, Massachusetts, and three naval shipyards. The remaining 24 "repeat Bensons" were authorized in 1940–42 and built at four Bethlehem Steel yards. They were laid down after the first group was commissioned. These plus the "repeat Livermores" (also known as "repeat Gleaveses") were also known at the time as the Bristol class. During World War II the Bensons were usually combined with the Livermores (more correctly the Gleaves class) as the Benson-Livermore class; this persisted in references until at least the 1960s. In some references both classes are combined and called the Benson class. The Benson- and Gleaves-class destroyers were the backbone of the pre-war Neutrality Patrols and participated in every major campaign of the war.
The lead ship of the class was named after William Shepherd Benson, a graduate of the Naval Academy in 1877. He commanded USS Albany, USS Missouri, USS Utah, and the Philadelphia Navy Yard. Benson was appointed first Chief of Naval Operations in 1915 and then served as CNO until he retired 25 September 1919. He died in Washington, D.C., 20 May 1932.
The Bensons were originally envisioned as a single class of 24 ships, the first eight of which were ordered in fiscal year 1938 (FY38). Six of these were designed by Bethlehem Shipbuilding, to be built at Bethlehem's Fore River and at several government yards (as mandated by Congress), and two were designed by Gibbs & Cox, to be built at Bath Iron Works. All were to have 600 psi (4,100 kPa) steam (references vary) superheated to 750 °F (399 °C), with cruising turbines and double-reduction gearing to maximize fuel efficiency. After contract award, Bethlehem requested that their design be modified to use less-complex single-reduction gears and no cruising turbines. Bethlehem claimed they could achieve comparable fuel efficiency with the simpler machinery. This request was granted, but FY39 and FY40 ships, beginning with Livermore, would use the more complex machinery. So the class was known through World War II as the Benson-Livermore class, and this name persisted in many references until at least the 1960s. In the spring of 1938 the Navy's Bureau of Steam Engineering requested that the FY39 and FY40 ships be modified for 850 °F (454 °C) superheat. It proved possible for Bath to build their two FY38 ships, Gleaves and Niblack, to the new design. Gleaves was completed prior to Livermore and had a lower hull number, thus the class name is more correctly the Benson-Gleaves class.
The only external difference between the Benson and Gleaves classes was the shape of the stacks; the Bensons' were flat-sided and the Gleaveses' were round.
After the Fall of France in 1940, and before the outcome of the looming Battle of Britain was certain, a rapid expansion of the Navy was envisioned. As not all facilities were equipped to produce the new Fletcher-class destroyers or because of other concerns, an additional 72 "repeat" Benson- and Gleaves-class ships were ordered in FY41. 24 repeat Bensons were built by several Bethlehem yards, while an additional 48 repeat Gleaveses were built by various other builders. These were initially called the Bristol class after Bristol, a repeat Gleaves and the first of these to be completed, although the machinery of the repeat Bensons was different from the repeat Gleaveses. The repeat ships were ordered with reduced torpedo and gun armament and increased anti-submarine and light anti-aircraft armament.
In some references the Benson and Gleaves classes are combined as the Benson class.
The Budget for the United States Government (as published) for fiscal year 41, starting on 1 July 1940 called for 8 destroyers to be built, and they were originally contemplated to be DD-445 ... DD-452, i.e. Fletchers. In June 1940, 8 Gleaves were ordered instead.
The Benson class was designed as an improved version of the Sims class with two stacks and a new "echeloned" machinery arrangement that featured alternating boiler and engine rooms, designed to give the ships a better chance at surviving torpedo damage. Loss of one compartment, or even two adjacent compartments, would no longer disable the entire propulsion system. They also introduced quintuple torpedo tube mounts. Their scantlings, or framing dimensions, were increased to carry the weight of the new machinery. This increased the ships' displacement by about sixty tons, to 1620 tons standard displacement.
