60-713: A ceremony held in Bandar Abbas on 14 June 2021. Future units of the Modge class are set to be equipped with the Sayyad-2 anti-aircraft missiles. During construction, frigate Talaiyeh suddenly capsized while in dry dock. Killing one Navy personnel, no official reports have been released by the Iranian authorities. Whilst in port at Bandas Abbas Sahand capsized on the 7 July 2024 before sinking on 9 July. Iran officially classifies these ships as destroyers , but this

90-463: A slow convoy (which in World War II would travel at 10 to 12 knots (19 to 22 km/h)), be able to defend against aircraft, and detect, pursue, and attack submarines . These lower requirements greatly reduce the size, cost, and crew required for the destroyer escort. Destroyer escorts were optimized for antisubmarine warfare, having a tighter turning radius and more specialized armament (such as

Warship International wrote in 2008 that four ships of this class were under construction: Mowj (376) launched on 22 February 2007, Jamaran (377) launched on 28 November 2007, as well as Azarakhsh (378) and Tondar (379). The first ship, Jamaran

150-699: Is rejected by most navies internationally. Alternatively, they have also been described as destroyer escorts . Sources differ in specifying the type of the class, either as light frigate or corvette . Jane's Fighting Ships classifies the class as FFG of frigate while the Military Balance of the International Institute of Strategic Studies (IISS), designates the ships in the class as FSGM or corvette.

According to OSGEOINT, Damavand was constructed at the Shahid Tamjidi Marine Industries (STMI) fabrication shop on the Caspian Sea at Bandar-e Anzali . The frigate was launched in March 2013. Damavand , based out of Bandar-Anzali on the Caspian Sea, ran aground on a concrete breakwater in

210-754: Is the Ticonderoga -class air-defense ship class, which is classified as cruiser , though it uses the same hull as the Spruance -class destroyers . During the Vietnam War , the Republic of Vietnam Navy received two Edsall -class destroyer escorts from the United States. total ships in the table: 507DEs + 56APDs 37 Buckleys listed here as Buckleys were converted to APDs after having been commissioned as destroyer escorts. All APDs listed in

240-650: The American Bureau of Shipping came up with a design which was known as the British destroyer escort (BDE). The BDE designation was retained by the first six destroyer escorts transferred to the United Kingdom (BDE 1, 2, 3, 4, 12, and 46); of the initial order of 50, these were the only ones the Royal Navy received, the rest being reclassified as destroyer escorts on 25 January 1943 and taken over by

270-752: The Evarts subclass and 46 from the Buckley subclass. Upon reaching the UK, the ships were substantially modified by the Royal Navy, including removal of torpedo tubes, making them distinct from the US Navy destroyer escort ships. Captain -class frigates acted in the roles of convoy escorts, antisubmarine warfare vessels, coastal forces control frigates and headquarters ships for the Normandy landings . During

300-577: The USSR , followed different naming conventions for this type of ship, which resulted in some confusion. To remedy this problem, the 1975 ship reclassification declared ocean escorts (and by extension, destroyer escorts) as frigates (FF). This brought the USN's nomenclature more in line with NATO, and made comparing ship types with the Soviet Union easier. As of 2006, no plans existed for future frigates for

330-646: The United States Navy . When the United States entered the war, and found they also required an antisubmarine warfare ship and that the destroyer escort fitted their needs perfectly, a system of rationing was put in place whereby out of every five destroyer escorts completed, four would be allocated to the U.S. Navy and one to the Royal Navy. Destroyer escorts were designed and built to naval construction standards, and as such could only be built at yards experienced with naval standards. The United States Maritime Commission created its S2-S2-AQ1 design – which

360-463: The Royal Navy, constructed in the United States, launched in 1942–1943 and delivered to the United Kingdom under the provisions of the Lend-Lease agreement (under which the United States supplied the United Kingdom and other Allied nations with materiel between 1941 and 1945), they were drawn from two subclasses of the destroyer escort (originally British destroyer escort) classification: 32 from

390-499: The US Navy. USS  Zumwalt and the littoral combat ship (LCS) were the main ship types planned in this area. However, by 2017 the Navy had reversed course, and put out a Request For Proposals (RFP) for a new frigate class, temporarily designated FFG(X) . One major problem with ship classification is whether to base it on a ship's role (such as escort or air defense), or on its size (such as displacement). One example of this ambiguity

420-518: The US for mass-production under Lend Lease as a less expensive alternative to fleet destroyers . The Royal Navy and Commonwealth forces identified such warships as frigates , and that classification was widely accepted when the United States redesignated destroyer escorts as frigates (FF) in 1975. From circa 1954 until 1975 new-build US Navy ships designated as destroyer escorts (DE) were called ocean escorts . Similar types of warships in other navies of

450-619: The United States Navy converted some of their World War II destroyers to escort destroyers (DDE). Full-sized destroyers must be able to steam as fast or faster than fast capital ships such as fleet carriers and cruisers . This typically requires a speed of 25–35 knots (46–65 km/h) (dependent upon the era and navy). They must carry torpedoes and a smaller caliber of cannon to use against enemy ships, as well as antisubmarine detection equipment and weapons. A destroyer escort needed only to be able to maneuver relative to

480-693: The amount payable under the provisions of the Lend-Lease agreement; the last such frigate was returned to United States custody in March 1956. Six Cannon -class destroyer escorts were built for the Free French Navy . Although initially transferred under the Lend-Lease Act, these ships were permanently transferred under the Mutual Defense Assistance Program (MDAP). Under the MDAP the destroyer escorts leased to

510-468: The colder North Atlantic Ocean), were criticized as far too hot below decks, and, because of the mercantile style of their hulls, had far less resistance to underwater explosions than ships built to naval standards like the destroyer escorts. After World War II, new-build United States Navy destroyer escorts were referred to as ocean escorts , but retained the hull classification symbol DE. However, other navies, most notably those of NATO countries and

540-403: The course of World War II, this class participated in the sinking of at least 34 German submarines and a number of other hostile craft with 15 of the 78 Captain -class frigates being either sunk or written off as a constructive total loss . In the postwar period, all of the surviving Captain -class frigates except one (HMS Hotham ) were returned to the US Navy before the end of 1947 to reduce

570-843: The engine room can be used equally well for other purposes, and after the war, many destroyer escorts were re-used as floating power stations for coastal cities in Latin America under programs funded by the World Bank . . Edsall -class ships were the exception to this and they used a geared diesel engine to drive the propellers directly. John C. Butler s used the typical boiler and geared turbine propulsion system. Destroyer escorts were also useful for coastal antisubmarine and radar picket ship duty. During World War II, seven destroyer escorts (DEs) were converted to radar picket destroyer escorts (DERs), supplementing radar picket destroyers. Although these were relegated to secondary roles after

600-407: The engine rooms functioned as power stations supplying current to electric motors sited close to the propellers. Electric drive was selected because it does not need gearboxes (produced on special precise machining tooling available in limited quantities, they were heavily in demand for the fast fleet destroyers) to adjust engine speed to the much lower optimal speed for the propellers. The current from

As an alternative to geared steam-turbine propulsion found in sloops of similar purpose, size and speed (as well as full-sized destroyers and larger warships), many US destroyer escorts of the World War II period had diesel-electric or turboelectric drive , in which

There has been little information released in reference to the cause of the grounding, with the exception of statements of wave height and visibility caused by the storm at the time of the grounding. Damavand is currently listed as actively commissioned. Photos from 2018 show that the ship's hull has broken apart near the waterline approximately at the start of the ship's aircraft deck.

720-547: The ship, from which landing craft ( LCVPs ) could be launched. The Lend-Lease Act was passed into law in the United States in March 1941, enabling the United Kingdom to procure merchant ships, warships, munitions, and other materiel from the US, to help with the war effort. This enabled the UK to commission the US to design, build, and supply an escort vessel that was suitable for antisubmarine warfare in deep open-ocean situations, which they did in June 1941. Captain E.L. Cochrane of

750-424: The table were completed as conversions. Captains were converted before commissioning as DEs.

780-595: The time included the 46 diesel powered Kaibōkan of the Imperial Japanese Navy , 10 Kriegsmarine F-class escort ships , and the two Amiral Murgescu -class vessels of the Romanian Navy . Postwar destroyer escorts and frigates were larger than those produced during wartime, with increased anti-aircraft capability, but remained smaller and slower than postwar destroyers. As Cold War destroyer escorts became as large as wartime destroyers,

810-435: The vicinity of its home port on 10 January 2018. It is believed probable that the incident was the result of navigational error, affected by a strong storm in the area, which created high wave heights and low visibility in the area. During the incident, six members of the ship's crew fell overboard. Four of those crew members were later rescued, and two were considered missing by media sources. The Iranian Navy declined to confirm

840-615: The war, in the mid-1950s, 36 more DEs were converted to DERs , serving as such until 1960–1965. Their mission was to extend the Distant Early Warning Line on both coasts, in conjunction with 16 Guardian -class radar picket ships , which were converted Liberty ships . During World War II, some 95 destroyer escorts were converted by the US to high-speed transports (APDs). This involved adding an extra deck which allowed space for about 10 officers and 150 men. Two large davits were also installed, one on either side of

870-693: Was based on the British-designed River class – for much the same role but using civilian construction standards. These ships would be classed by the Navy as the Tacoma class frigates (PF) . These frigates had a greater range than the superficially similar destroyer escorts, but the US Navy viewed them as decidedly inferior in all other respects. The Tacoma class had a much larger turning circle than destroyer escorts, lacked sufficient ventilation for warm-weather operations (a reflection of their original British design and its emphasis on operations in

900-552: Was the United States Navy mid-20th-century classification for a 20-knot (37 km/h; 23 mph) warship designed with the endurance necessary to escort mid-ocean convoys of merchant marine ships. Development of the destroyer escort was promoted by the British need in World War II for anti-submarine ships that could operate in open oceans at speeds of up to 20 knots. These "British Destroyer Escort"s were designed by
