Armament

The Evarts-class destroyer escorts were destroyer escorts launched in the United States in 1942–44. They served in World War II as convoy escorts and anti-submarine warfare ships. They were also known as the GMT or "short hull" DE class, with GMT standing for General Motors Tandem Diesel drive.

The lead ship was USS Evarts, launched on 7 December 1942, exactly a year after the attack on Pearl Harbor. The first ship to be completed was commissioned on 20 January 1943 at the Boston Navy Yard; it was delivered to the Royal Navy under the Lend-Lease provisions and became HMS Bayntun. Evarts-class ships were driven by diesel-electric power with four diesel engines mounted in tandem with electric drives. The ships were prefabricated in sections at various factories in the United States and the units brought together in the shipyards, where they were welded together on the slipways. The original design specified eight engines for 24 knots but other priority programs forced the use of only four with a consequent shortening of the hull.[1]

In all, 105 Evarts-class ships were ordered with 8 later being cancelled. The United States Navy commissioned 65 while 32 Evarts-class ships were delivered to the Royal Navy. They were classed as frigates and named after captains of the Napoleonic Wars and formed part of the Captain class along with 46 ships of the Buckley class.

Evarts-class destroyer escort

View on Grokipedia
from Grokipedia
The Evarts-class destroyer escorts were a group of small, mass-produced warships developed by the during specifically for and convoy protection in response to the German threat. Featuring a compact design with diesel-electric propulsion, they represented the Navy's first dedicated class of these versatile escorts, emphasizing speed of construction over advanced performance. A total of 97 ships were built between 1942 and 1944 across several U.S. shipyards, with approximately one-third transferred to the Royal Navy under the program, where they served as the Captain class. The class originated from a British request for inexpensive escort vessels amid escalating Atlantic losses, leading to a design adapted for U.S. production constraints, including shortages of traditional steam turbines and reduction gears. The first ships were laid down in late and commissioned starting in April 1943, with construction prioritized at yards like , , Navy Yard, and to meet urgent wartime needs. At 289 feet in length with a beam of 35 feet and a standard displacement of 1,140 tons (rising to 1,430 tons full load), these vessels had a high open bridge and a single stack, but they were criticized for poor seaworthiness and a tendency to roll in heavy weather due to their short hulls. Propulsion came from four 1,500-horsepower diesel engines driving electric motors for a top speed of 21 knots and a range of about 6,000 nautical miles at 12 knots. Armed primarily for anti-submarine operations, each Evarts-class ship carried three 3-inch/50-caliber dual-purpose guns in single mounts, supplemented by anti-aircraft weaponry such as one quadruple 40 mm gun (added later) and up to nine 20 mm Oerlikon guns. Their offensive suite included a forward-throwing anti-submarine projector, eight projectors, two tracks, and later and upgrades for improved detection. Unlike larger destroyers, they lacked torpedo tubes as built, focusing instead on economy and specialization, with a complement of 15 officers and 183 enlisted men. In service, the Evarts class proved effective in hunter-killer groups and escorting transatlantic and Pacific convoys, contributing to the turning tide against U-boats without any losses in U.S. Navy operation, though two examples were damaged. Notable actions included USS Rall (DE-304) earning a for anti-kamikaze defense off Okinawa in April 1945. Post-war, most were decommissioned by 1946 and scrapped or transferred, marking the end of their brief but critical role in Allied naval strategy.

Development

Background and origins

In 1941, the escalating in the Atlantic posed a severe threat to Allied shipping, with German submarines sinking hundreds of merchant vessels and risking Britain's supply lines, prompting urgent calls for mass-produced anti-submarine escorts under the program to bolster British defenses. The U.S. Navy, anticipating its own involvement in the conflict, recognized the need for inexpensive, specialized vessels to supplement dwindling numbers without diverting resources from larger fleet units. On August 15, 1941, President authorized the construction of 50 destroyer escorts under for transfer to Britain, designated BDE-1 through BDE-50, drawing design inspiration from the British Hunt-class destroyers to facilitate rapid U.S. production and address the Royal Navy's acute escort shortages. These vessels were adapted for simpler manufacturing, emphasizing convoy protection over high-speed fleet actions, with initial contracts awarded in November 1941 to four naval shipyards. Subsequent orders expanded the program to a planned total of 105 ships, reflecting growing production capacity amid wartime demands. Following the U.S. entry into after , the Navy decided in early 1942 to retain a significant portion of the BDE series for its own use, renaming them as the Evarts class to counter the intensifying submarine threat in American waters. This shift was influenced by the ' collaboration with , which proposed a diesel-electric propulsion system using readily available components to circumvent shortages of steam turbines and reduction gears, enabling faster construction without compromising essential anti-submarine capabilities.

Design process

The design of the Evarts-class destroyer escorts, developed by , began as an adaptation of the British Hunt-class Type II escort destroyer, requested by the Royal Navy through the Mills-Cochrane mission in late 1940 to meet urgent protection needs amid threats. U.S. naval architects modified the Hunt-class for prefabricated construction suited to American shipyards, emphasizing all-welded hulls assembled on slipways to accelerate production while focusing on capabilities, including initial plans for dual 5-inch gun mounts that were later changed to three 3-inch/50-caliber guns due to production constraints, along with projectors. This adaptation incorporated modular sections for easier assembly, drawing on lessons from earlier U.S. flush-deck designs to simplify fabrication without specialized riveting equipment. A major engineering shift occurred in early 1942 when wartime shortages of reduction gears—prioritized for larger destroyers and submarines—prompted the abandonment of the original propulsion in favor of a diesel-electric system. The selected Tandem Drive (GMT) configuration utilized four 16-278A diesel engines, each rated at 1,500 horsepower, paired with electric motors for propulsion, enabling tandem operation on two shafts while reducing complexity and material demands. This change, though it added about 33 feet to the hull length and 130 tons of displacement compared to the initial Hunt-derived plans, allowed for quicker installation using components already mass-produced for . To further expedite building, the hull was configured as a "short hull" variant measuring approximately 289 feet overall, featuring a simplified with a tall, enclosed bridge inspired by British practices for better visibility in poor weather. The design eliminated extraneous fittings, such as complex gun platforms, and divided the vessel into prefabricated modules that could be welded together rapidly, addressing stability concerns from the narrower Hunt-class Type I by widening the beam slightly for improved seaworthiness. The initial performance target of 24 knots, aligned with the Hunt-class specifications, was compromised to 19-21 knots to emphasize reliability, , and the limitations of the underpowered diesel-electric setup, which prioritized over sprint speed for transatlantic escort duties. Early validation involved prototype development and model basin trials conducted in 1942 at U.S. experimental facilities, where scaled models underwent tow-tank testing to confirm , reduce tendencies toward pronounced rolling observed in preliminary sketches, and ensure seaworthiness in rough seas. These tests refined the hull form iteratively, balancing the trade-offs between speed reductions and anti-submarine effectiveness before full-scale commenced.

Description

General characteristics

The Evarts-class destroyer escorts were compact warships designed for , featuring a standard displacement of 1,140 long tons and a full load displacement of 1,360 to 1,430 long tons. These vessels measured 289 feet 6 inches (88.2 m) in overall , with a beam of 35 feet (10.7 m) and a mean draft of 9 feet (2.7 m). The ship's complement totaled 198 personnel, comprising 15 officers and 183 enlisted men. The hull was constructed from welded steel plates, prefabricated in modular sections at various U.S. factories to accelerate production, and assembled with a single-stack design to simplify operations and reduce complexity. These destroyer escorts achieved an endurance of 5,000 nautical miles at 15 knots, supporting extended convoy escort duties across the Atlantic and Pacific. The class employed a diesel-electric , which contributed to their economical operation for long-range patrols.

Propulsion and performance

The Evarts-class destroyer escorts employed a diesel-electric propulsion system, consisting of four Model 16-278A 16-cylinder, two-stroke marine diesel engines coupled to generators that powered two electric motors on twin shafts. This configuration delivered a total of 6,000 shaft horsepower (shp), prioritizing reliability and over high-speed performance for anti-submarine convoy escort duties. The adoption of this Tandem Drive (GMT) arrangement allowed for simpler maintenance using off-the-shelf components, though it limited maximum output compared to alternatives. Operational speeds for the class reached a service maximum of 19 knots, with many vessels demonstrating 21 to 22 knots during sea trials under optimal conditions. Fuel capacity varied slightly by ship but typically ranged from 131 to 197 tons of diesel oil, enabling an endurance of approximately 5,000 nautical miles at 15 knots or up to 6,000 nautical miles at 12 knots—sufficient for extended transatlantic patrols without frequent refueling. These metrics underscored the class's design focus on long-range loitering rather than rapid response, contrasting with faster fleet destroyers that exceeded 30 knots but consumed far more fuel. Maneuverability was enhanced by twin screws and rudders, providing a tactical turning circle of around 450 yards, which proved effective for close-quarters anti-submarine maneuvers in formations. The vessels exhibited good stability in moderate seas, aided by anti-roll keels, but their low freeboard contributed to handling challenges in high winds and rough conditions, occasionally leading to excessive rolling. Overall, while slower than contemporary classes, the Evarts-class propulsion optimized endurance and operational economy, making it well-suited for the of the .

Armament

The Evarts-class destroyer escorts were armed with three 3-inch/50 caliber Mark 20 dual-purpose guns mounted singly, consisting of one forward and two aft to provide balanced against surface and aerial threats while maintaining an emphasis on . These guns fired 13-pound high-explosive shells with a maximum range of 14,600 yards at 43 degrees elevation and an anti-aircraft ceiling of 30,400 feet, supporting rapid fire rates of up to 20 rounds per minute per . Each mount carried provisions for 300 rounds of , enabling sustained engagement during protection operations. For close-range anti-aircraft defense, the class initially featured eight single 20 mm Oerlikon cannons distributed along the deck for protection against low-flying aircraft, later augmented in many ships with one quadruple 40 mm mount amidships to enhance firepower against air attacks. Some early units carried a single quadruple 1.1-inch mount instead of the initial 40 mm configuration, but this was phased out in favor of the more effective guns as production progressed. The primary focus of the armament was , with one forward-firing mortar capable of launching 24 projectiles in a spread pattern to engage submerged threats at ranges up to 250 yards. This was supplemented by eight K-gun projectors—four per side aft—for throwing 300- to 600-pound charges up to 250 yards sideways, and two stern tracks that could hold and launch up to 160 total s for area coverage. Unlike later destroyer escort classes such as the Buckley or , the Evarts-class omitted torpedo tubes to prioritize anti-submarine loadout and simplify construction for . The overall arrangement allowed for quick reloading and deployment of weapons during escort duties, with the hull layout supporting efficient placement of the forward and aft K-guns without compromising stability.

Electronics and sensors

The Evarts-class destroyer escorts were equipped with systems derived from British designs to fulfill their primary (ASW) role. Early ships featured the Type 128D ASDIC, an active housed in a retractable dome beneath the , which provided bearing and range data on submerged targets through echo location. Later vessels incorporated the improved Type 144 ASDIC, a gyro-stabilized passive-active system in a retractable dome, integrated with ASW weapons like mortar for more precise depth and bearing information, achieving detection ranges of approximately 2,800 to 3,000 yards under optimal conditions at low speeds. Surface and air search radars formed the core of the class's detection capabilities. All ships carried the SL surface-search radar as standard, operating on a 10 cm with a (PPI) scope, offering reliable detection up to 20 nautical miles on large surface vessels for navigation and threat identification. Later production models added the SA air-search radar, a long-wave set providing ranges of up to 40 miles against medium bombers at 10,000 feet altitude, enhancing low-altitude detection despite its initial A-scope display limitations. Fire control systems emphasized optical and basic electronic aids suited to the class's armament. The Mark 63 Fire Control System (GFCS), comprising optical directors and radar-assisted tracking, directed the 3-inch dual-purpose guns against surface and air targets, with manual operation for ranges from 800 to 7,000 yards. Complementing this was a basic (HF/DF) setup using the FH 4 antenna, mounted on the mast to intercept and triangulate radio signals for passive localization. Communications relied on the standard U.S. radio suite for operations, including voice-capable Talk Between Ships (TBS) equipment on VHF frequencies to enable real-time coordination among escorts and merchant vessels over distances of several miles. Early Evarts-class ships suffered from limited electronic countermeasures (ECM), lacking dedicated jamming or deception gear against Axis radar, which exposed them to detection in contested waters. Mid-1944 upgrades introduced (IFF) Mark III transponders to allied aircraft and ships, reducing risks during joint operations.

Construction

Production program

The production program for the Evarts-class destroyer escorts was initiated in response to urgent wartime needs for convoy protection in the Atlantic, with contracts awarded between 1941 and 1942 for a total of 105 ships to enable rapid . The initial order, approved on August 15, 1941, called for 50 vessels designated as British Destroyer Escorts (BDEs) under the Act to bolster capabilities, but the program was expanded amid escalating threats. Construction timelines reflected this urgency, with the first keel laid on February 12, 1942, for USS Andres (DE-45), and subsequent keels following quickly, including additional early starts in April 1942 at facilities like Navy Yard. The program emphasized techniques to streamline assembly, allowing for accelerated output to meet escort demands by mid-1943. Of the 105 planned ships, 97 were ultimately completed, spanning hull numbers DE-5 to DE-101 with some gaps due to reassignments and modifications, while 8 were cancelled in 1944 as naval priorities shifted toward more advanced designs and the end of major U-boat campaigns. The first ship, USS Evarts (DE-5), had its keel laid in October 1942 and was commissioned in , with the majority delivered by late 1943 and the last completed in early 1944. This schedule enabled the U.S. Navy to commission 65 vessels for its own use, while 32 were transferred to the Royal Navy as the Captain-class frigates, a reduction from the initial 50 allocation due to American retention needs for Pacific operations. To address material shortages and production bottlenecks, particularly in reduction gears and high-priority diesel engines needed for and , the program underwent significant adjustments, including a reduction in the number of engines per ship from eight 1,500-horsepower diesels to four, which shortened the hull and lowered top speed but accelerated overall output. These changes prioritized quantity over performance, aligning with the class's role as an inexpensive, mass-produced escort—estimated at roughly half the cost of a full fleet —to fulfill the surge in anti-submarine requirements without diverting resources from larger warships.

Shipyards

The Evarts-class destroyer escorts were constructed across four key U.S. shipyards—Boston Navy Yard, Mare Island Navy Yard, Philadelphia Navy Yard, and Puget Sound Navy Yard—each contributing to the program's rapid expansion during . These facilities leveraged techniques to assemble the diesel-electric powered vessels efficiently, with a total of 97 ships completed, some of which were transferred to the Royal . All shipyards employed construction methods, enabling build times of approximately 90 days from to delivery, which was critical for meeting wartime demands. This approach involved assembling prefabricated sections on inclined slipways before launching, supported by a that integrated civilian labor under direct oversight to maximize output.

Operational history

World War II service

The Evarts-class destroyer escorts played a vital role in (ASW) and convoy protection during , with the majority of the 65 U.S. Navy ships commissioned between 1943 and 1944 deploying to the Atlantic and Pacific theaters. In the Atlantic, these vessels primarily conducted escort duties for transatlantic convoys bound for the and , including operations to ports such as and , contributing to the sharp decline in successes after the first half of 1943 as Allied escort forces overwhelmed German submarine operations. Integrated into hunter-killer groups centered around escort carriers, Evarts-class ships screened merchant vessels and fast troop transports, performing and attacks on suspected contacts while also providing limited anti-aircraft defense against bombers. For instance, USS Wyffels (DE-6) repelled multiple Ju-88 dive-bomber attacks on convoy UGS-40 in May 1944, laying smoke screens and firing her 3-inch guns to protect the formation en route to the Mediterranean. ASW engagements highlighted the class's effectiveness in cooperative operations, though confirmed sinkings were often shared with other units; notable successes included USS Gilmore (DE-18), which helped destroy I-180 southwest of Chirikof Island in the Aleutians in April 1944. No U.S. Evarts-class ships were lost to enemy action during the war, underscoring their robustness in routine patrols and convoy screens, but the Royal Navy's Captain-class frigates—derived from Evarts designs—suffered seven losses overall, including HMS Capel (ex-USS Booth, DE-170), sunk by U-486 on 26 December 1944 northeast of , , and HMS Goodall (ex-USS Magoffin, DE-306), sunk by U-286 on 29 April 1945 in the Kola Inlet near . These incidents reflected the hazards faced by the transferred vessels in European and Arctic waters, where they bolstered British escort groups against late-war sorties. In the Pacific theater, Evarts-class escorts shifted to amphibious support roles starting in late 1943, screening invasion forces and providing ASW protection for fast carrier task forces and transport groups during the island-hopping campaign. Ships like USS Whitman (DE-24) supported operations in the and Marianas in 1944, including patrols around Saipan and while rescuing downed aviators. By 1945, they were integral to the massive assaults on and Okinawa, where they screened battleships and transports against threats and conducted . A standout example was USS Rall (DE-304), which on April 12, 1945, off Ie Shima near Okinawa, downed three kamikazes with her guns during a 14-plane assault, though a fifth struck her starboard side, killing 21 and wounding 38; Rall's crew extinguished fires and maintained station, earning the for their actions in repelling the attack. Throughout their service, Evarts-class ships faced operational challenges from their diesel-electric , which proved underpowered for sustained high speeds and prone to mechanical breakdowns, particularly in tropical climates where overheating and vibration issues plagued the General Motors engines during extended Pacific patrols. These problems led to frequent repairs, as seen with USS Whitman undergoing engine work in January 1944 at , but were partially mitigated by mid-1944 refits that improved cooling systems and reliability for frontline duties. Overall, the class's over 65 active U.S. vessels screened thousands of merchant and warship transits without a single loss, exemplifying their value in securing Allied supply lines and enabling amphibious advances across both oceans.

Post-war service and legacy

Following the end of , the majority of Evarts-class destroyer escorts in U.S. service were rapidly inactivated between late 1945 and early 1946, with full decommissioning completed by 1947. These vessels were then placed in the , where they remained in storage as part of the postwar naval drawdown. A small number continued limited roles in reserve training and coastal anti-submarine patrols before being fully retired. Two Evarts-class ships were transferred to foreign navies under postwar aid programs: USS Wyffels (DE-6) and USS Decker (DE-47) were permanently loaned to the Republic of China in February 1948, where they served as ROCS Tai Kang and ROCS Tai Ping, respectively, until Tai Ping was sunk in 1954 during the Chinese Civil War. The majority of the class, however, faced disposal amid naval reduction efforts; most were struck from the Navy Register between 1946 and 1950 and sold for scrapping, with examples including USS Evarts (DE-5) broken up in July 1946 and USS Whitman (DE-24) in January 1947. The Evarts class pioneered the U.S. Navy's dedicated concept, validating of smaller, cost-effective anti-submarine vessels and directly influencing the of subsequent Buckley- and Rudderow-class escorts by highlighting needs for improved hull length, range, and sea-keeping. Their diesel-electric demonstrated viability for escort duties, offering reliable tandem-drive despite initial concerns over speed and complexity, and the class sustained no combat losses during the war, underscoring the robustness of their prefabricated construction. Overall, the Evarts escorts contributed significantly to the Allied effort by protecting Atlantic and Pacific convoys, helping to neutralize the threat and secure vital supply lines. No Evarts-class ships survive as museum vessels today, though artifacts such as equipment and documentation are preserved in naval collections, and the class's legacy is represented through similar destroyer escorts like the Cannon-class USS Slater, maintained as a .

List of ships

United States Navy ships

The Evarts-class destroyer escorts included 65 vessels commissioned into the , bearing hull numbers primarily from DE-5 to DE-101 (with gaps for intervening classes), as well as later blocks such as DE-256–DE-265 and DE-301–DE-314. These ships were named in accordance with U.S. Navy conventions for destroyer escorts, honoring officers and enlisted personnel, for example, USS Griswold (DE-7) after Dwight Griswold. Commissioning began with the first wave in 1943, encompassing DE-5 through DE-28, starting with USS Evarts (DE-5) on 15 April 1943 at the . The production pace accelerated, reaching a peak in 1944 for higher hull numbers, such as USS Rall (DE-304), commissioned 27 April 1944 and noted for service at Okinawa. Builders included major naval yards like , , Charleston, and . No Evarts-class ships were lost in , reflecting their effective employment in anti-submarine roles. Over 50 vessels were decommissioned between late 1945 and 1946, then placed in reserve fleets through the 1950s before being sold for scrapping, primarily in 1946–1948.

Ships transferred to other navies

Thirty-two Evarts-class destroyer escorts were transferred to the Royal Navy under the Lend-Lease program between 1943 and 1945, where they were redesignated as Captain-class frigates (GMT subgroup) and employed primarily in anti-submarine warfare roles during World War II. These vessels, initially designated as British Destroyer Escorts (BDEs) before receiving their final hull numbers, were adapted with British armament configurations, including twin 4-inch guns forward and additional depth charge provisions, to better suit Royal Navy operations in the North Atlantic. They participated in convoy escorts, contributing to the sinking of numerous U-boats, and supported amphibious operations such as the Normandy landings. Two were lost in action: HMS Capel (K470, ex-DE-37 USS Greiner) to U-1198 on 26 December 1944, and HMS Goodall (K479, ex-DE-15 USS Austin) to U-978 on 29 April 1945; others suffered damage but were repaired or returned. None of the transferred ships were lost prior to entering British service, and their diesel-electric propulsion proved reliable for extended patrols, though maintenance challenges arose due to the novel tandem-drive system. The naming convention for these frigates followed a honoring British naval captains from the , particularly those associated with Vice-Admiral Horatio Nelson's victories, such as HMS Bayntun (K310, ex-DE-5 USS Evarts), named for William Bayntun of HMS Anson, and HMS Waveney (K248, ex-DE-6 USS Wyffels), after John Waveney of HMS Romney. This thematic renaming distinguished them from Buckley-class transfers in the same program, emphasizing historical ties to Britain's maritime heritage. By war's end in 1945, the surviving ships were returned to the for decommissioning, with most scrapped or placed in reserve. Post-war transfers under the Mutual Defense Assistance Program were limited for Evarts-class vessels. Two ships were leased to the in August 1945 and permanently transferred in February 1948: USS Wyffels (DE-6) as ROCS Tai Kang (PF-21), which served through the and escaped to before decommissioning in the 1950s, and USS Decker (DE-47) as ROCS Tai Ping (PF-22), which participated in coastal defense operations until sunk by Communist Chinese torpedo boats on 14 November 1954 during the Battle of Zhejiang. These transfers retained U.S. hull configurations with minimal modifications, focusing on anti-submarine and patrol duties amid the escalating civil conflict. No confirmed post-war transfers of Evarts-class ships to France or ; such examples pertain to other destroyer escort classes like or Buckley.
