The Claud Jones-class destroyer escorts were four destroyer escorts built for the United States Navy in the late 1950s. These ships were a diesel-powered version of the earlier Dealey class and were designed with the aim of producing a cheaper ship suitable for rapid production in wartime. These ships also had reduced armament and speed compared to their predecessors. They were not seen as effective anti-submarine warfare vessels by the United States Navy and were sold after only 15 years service to the Indonesian Navy.

Description[]

The class was designed under project SCB 131 as a cost-effective version of an anti-submarine warfare (ASW) ship that could be built quickly in case of rapid mobilization.[1] The Claud Jones class had a standard displacement of 1,314 long tons (1,335 t) and were 1,916 long tons (1,947 t) at full load. The destroyer escorts were 301 feet 0 inches (91.7 m) long at the waterline and 312 feet 0 inches (95.1 m) overall with a beam of 38 feet 0 inches (11.6 m) and a draft of 12 feet 11 inches (3.9 m).[2] The Claud Jones class had an aluminum superstructure, a tripod mast forward and a further back amidships, with two stacks.[3][a]

Following the guidelines given to them, the designers chose a two-shafted diesel-powered ship to maximize cost effectiveness.[2] The Claud Jones class were given four Fairbanks Morse 38ND8 diesel engines rated at 9,200 brake horsepower (6,860 kW).[3] The class had a range of 7,000 nautical miles (12,964 km; 8,055 mi) at 12 knots (22 km/h; 14 mph) and a maximum speed of 22 knots (41 km/h; 25 mph).[2][3][b]

The ships were initially armed with two 3-inch (76 mm)/50 caliber guns, one located forward with a closed shield and one located aft with an open shield.[c] For ASW, the destroyer escorts were equipped with two forward-firing hedgehog anti-submarine mortars, two fixed 12.75-inch (324 mm) torpedo tubes for and one depth charge rack placed over the stern. The fixed torpedo tubes were later removed and replaced with two triple tube mounts.[2][3] In 1961, Charles Berry and McMorris received a Norwegian-designed depth charge system deployed via rockets.[2]

The Claud Jones class was initially equipped with variable depth sonar, AN/SPS-10 and AN/SPS-6 search radars and hull-mounted sonar. The variable depth sonar was later removed. The vessels had a ship's company of 175 with 15 officers and 160 enlisted personnel.[3] The class was not well-received and the designers were ordered to come back with another design, leading to the successor Bronstein-class frigates.[2]

Indonesian service[]

The four vessels of the class were transferred to the Indonesian Navy in 1973–1974. In Indonesian service, Samadikun (ex-John R. Perry) and Martadinata (ex-Charles Berry) had one of the 3-inch guns removed and given Soviet twin-mounted 37 mm (1.46 in) guns and twin-mounted 25 mm (0.98 in) guns. Monginsidi (ex-Claud Jones) and Ngurah Rai (ex-McMorris) kept their two 3-inch mounts and had twin-mounted 25 mm guns added.[4]

Notes[]

  1. ^ The Claud Jones-ships' displacement is stated by Moore as 1,450 long tons (1,470 t) standard and 1,750 long tons (1,780 t) at full load.
  2. ^ Moore states that the vessels had only one shaft, while Gardiner, Chumbley & Budzbon state the ships' engines were rated at 8,700 brake horsepower (6,500 kW).
  3. ^ The 50 caliber denotes the length of the gun. This means that the length of the gun barrel is 50 times the bore diameter.
