Claud Jones-class destroyer escort

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 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. The "Claud Jones" class had a standard displacement of and were at full load. The destroyer escorts were long at the waterline and overall with a beam of and a draft of . The "Claud Jones" class had an aluminum superstructure, a tripod mast forward and a pole mast further back amidships, with two stacks.
Following the guidelines given to them, the designers chose a two-shafted diesel-powered ship to maximize cost effectiveness. The "Claud Jones" class were given four Fairbanks Morse 38ND8 diesel engines rated at . The class had a range of at and a maximum speed of .
The ships were initially armed with two /50 caliber guns, one located forward with a closed shield and one located aft with an open shield. For ASW, the destroyer escorts were equipped with two forward-firing hedgehog anti-submarine mortars, two fixed torpedo tubes for Mk 32 torpedoes and one depth charge rack placed over the stern. The fixed torpedo tubes were later removed and replaced with two triple tube mounts. In 1961, "Charles Berry" and "McMorris" received a Norwegian-designed Terne III depth charge system deployed via rockets.
The "Claud Jones" class was initially equipped with variable depth sonar, SPS-10 and SPS-6 search radars and SQS-29/32 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. The class was not well-received and the designers were ordered to come back with another design, leading to the successor s.
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 guns and twin-mounted guns. "Monginsidi" (ex-"Claud Jones") and "Ngurah Rai" (ex-"McMorris") kept their two 3-inch mounts and had twin-mounted 25 mm guns added.
