Fletcher-class Destroyer

The ''Fletcher'' class was a class of destroyers built by the United States during World War II. The class was designed in 1939, as a result of dissatisfaction with the earlier destroyer leader types of the and classes. Some went on to serve during the Korean War and into the Vietnam War.

The United States Navy commissioned 175 ''Fletcher''-class destroyers between 1942 and 1944, more than any other destroyer class, and the design was generally regarded as highly successful. The ''Fletcher''s had a design speed of and a principal armament of five guns in single mounts with ten torpedo tubes in two quintuple centerline mounts. The and classes were ''Fletcher'' derivatives.

The long-range ''Fletcher''-class ships performed every task asked of a destroyer, from anti-submarine warfare and anti-aircraft warfare to surface action.Friedman pp. 111–112. They could cover the vast distances required by fleet actions in the Pacific and served almost exclusively in the Pacific Theater of Operations during World War II, during which they accounted for 29 Imperial Japanese Navy submarines sunk. In a massive effort, the ''Fletcher''s were built by shipyards across the United States, and, after World War II ended, 11 were sold to countries that they had been built to fight against: Italy, Germany, and Japan, as well as other countries, where they had even longer, distinguished careers. Three have been preserved as museum ships in the U.S. and one in Greece.

Description

The ''Fletcher'' class (named for Admiral Frank F. Fletcher, Medal of Honor recipient) was the largest destroyer class ordered. It was also one of the most successful and popular with their crews. Compared to earlier classes built for the United States Navy, the ''Fletcher''s carried a significant increase in lethal firepower, including anti-aircraft (AA) weapons and increased armor plating; this contributed to greater displacement and overall weight and height increase. Their flush deck construction added structural strength; however, it did make them cramped, as less crew space was available below decks compared with a raised forecastle.

Design

The ''Fletcher'' class was the first generation of destroyers designed after the series of naval treaties that had limited ship designs heretofore. The growth in the design was in part a response to the challenge that had dogged U.S. Navy designs in coping with long range operations in the Pacific Ocean. They were also to carry no fewer than five guns and ten deck-mounted torpedo tubes on the centerline, allowing them to meet any foreign design on equal terms. Compared to earlier designs, the ''Fletcher''s were large, allowing them to adapt to evolving defensive priorities through the addition of two Bofors quadruple mount AA guns as well as six Oerlikon dual AA gun positions. This addition to the AA suite required the deletion of the forward quintuple torpedo mount, a change done under the 4 April 1945 anti-''kamikaze'' program.

''Fletcher''s were also much less top-heavy than previous classes, allowing them to take on additional equipment and weapons without major redesign. They were fortunate in catching American production at the right moment, becoming "the" destroyer design, with only the ''Fletcher''-class derivatives, the and classes, following it.

The first design inputs were in the fall of 1939 from questionnaires distributed around design bureaus and the Office of the Chief of Naval Operations. The design parameters were the armaments desired of the next destroyer. As such, the questions were of how many guns, torpedoes, and depth charges were seen as desirable. Also asked was at what point would the design grow large enough to become a torpedo target instead of a torpedo delivery system. The answer that came back was that five dual-purpose guns, twelve torpedoes, and twenty-eight depth charges would be ideal, while a return to the 1,500-ton designs of the past was seen as undesirable. Speed requirements varied from , and shortcomings in the earlier , which were top-heavy and needed lead ballast to correct this fault, caused the ''Fletcher'' design to be widened by of beam. As with other previous U.S. flush deck destroyer designs, seagoing performance suffered. This was mitigated by deployment to the Pacific Ocean, which is relatively calm compared to the Atlantic.Friedman, p. 111.

To achieve 38 knots with a 500-ton increase in displacement, power was increased from to compared to the previous and classes. The ''Fletcher''s featured air-encased boilers producing steam at and , with two 350 kW steam turbine driven electrical generators and a 100 kW emergency diesel generator. Typically, Babcock & Wilcox boilers and General Electric geared steam turbines were equipped, although other designs and manufacturers were probably used to maximize the rate of production.

Armament

Main gun armament was five dual-purpose 5-inch/38 caliber (127 mm) guns in single Mk 30 turrets, guided by a Mark 37 Gun Fire Control System, including a Mk 12 fire control radar and a Mk 22 height-finder (replaced by the circular Mk 25 radar postwar) linked by a Mark 1A Fire Control Computer and stabilized by a Mk 6 8500 rpm gyroscope.

Ten torpedo tubes were fitted in two quintuple mounts amidships, firing the 21-inch Mark 15 torpedo. Anti-submarine armament was two racks for depth charges at the stern and six K-gun 300-pound depth charge throwers amidships.

Anti-aircraft armament initially was light, with a quadruple 1.1"/75 caliber gun located in an elevated tub between the number three and four 5-inch gun mounts and six Oerlikon 20 mm cannons (two in front of and below the bridge and four amidships). In June 1942, the 1.1" gun was replaced by a twin Bofors 40 mm gun mount; in some ships, another twin mount may have been added on the fantail between the depth charge racks. In February 1943, the fantail-mounted Bofors was removed and one twin mount was placed on each side of the aft funnel, bringing the total number of 40 mm to six.

In 1942 and 1943, the number of Oerlikon cannons was steadily increased with ships modified before leaving the shipyard with a seventh 20 mm mount in front of the bridge behind the number two 5" gun mount and anywhere from one to three mounts on the flying bridge depending upon the configuration of the ship. In combat, commanders often requisitioned additional guns with some ships mounting up to thirteen 20 mm cannons. In June and July 1943, two more twin Bofors mounts were added in place of the 20 mm cannons in front of and below the bridge, giving a total of ten. With this modification, the Oerlikon cannons were rearranged and their number was standardized at seven; four amidships and three in a heart-shaped mount on the fantail.

Due to the increasing threat from ''kamikaze'' attacks, beginning in July 1945 some ships returning to the United States for refits received further anti-aircraft modifications, replacing the forward set of torpedo tubes with gun platforms housing two quadruple 40 mm guns (for a total of eighteen). The seven single 20 mm guns were replaced with six twin mounts (four amidships and two on the fantail.

Three (, and ) were built with aircraft catapults after deletion of the rear torpedo tube mount and the number 3 5-inch gun mount. This alteration was not a success and was not repeated. These three destroyers were later converted to the regular ''Fletcher''-class configuration.

Service

Nineteen ''Fletcher''s were lost during World War II; six more were damaged, evaluated as constructive total losses, and not repaired. Postwar, the remainder were decommissioned and put into reserve.

Korean War

With the outbreak of the Korean War many were returned to active duty. During this time 39 were refitted under project SCB 74A, reducing their overall main armament and the number of torpedo tubes to accommodate other weapons. A new ahead-throwing weapon called Weapon Alpha was installed in many of the ships. Others carried trainable Hedgehogs. Eighteen ships were redesignated as escort destroyers (DDE), optimized for anti-submarine warfare; these reverted to destroyer (DD) designation in 1962.

Other navies

Many of the ships were sold to other navies during the mid-1950s, including:

Any remaining were broken up in the 1970s. The last ''Fletcher'' in service, BAM ''Cuitlahuac'' (ex-''John Rodgers''), left the Mexican navy in 2001, meaning the total service life of the ''Fletcher''s stretched over almost six decades and into the 21st century.

Surviving ships

Four ''Fletcher''-class destroyers are preserved as museum ships. Three are in the United States and one is in Greece, although only ''Kidd'' retains her World War II configuration.

''Velos'' is the only vessel still in commission. ''Velos'' alongside ''G. Averof'' are ceremonially commissioned by the Hellenic Navy having Palaio Faliro as their base. Their crew are active Officers of Hellenic Navy. ''Velos'' still retains its complete armament and equipment(as modernized in 1950s). In September 2019 its crew took her to Thessaloniki for a short 3-month stay. , she remains in Thessaloniki and she has been visited by over 157.000 visitors.

All three American museum ships have been designated as National Historic Landmarks.
