Upgraded systems included SQS-23 sonar, SPS-10 surface search radar, 2 triple Mark 32 torpedo tubes, 8-cell Anti-Submarine Rocket (ASROC) box launcher, and one QH-50C DASH ASW drone helicopter, with its own landing pad and hangar.

With ASROC continuing to provide a standoff ASW capability, the Gearings were retained in service for several years, with most being decommissioned and transferred to foreign navies 1973-80. (later cancelled), DD-896 to DD-904 awarded to Bath Iron Works, Bath, Maine. A limitation of drones in ASW was the need to re-acquire the target at ranges beyond the effectiveness of the controlling ship's sonar. Many of the Gearings provided significant gunfire support in the Vietnam War. [26][27], On 14 April 2022, museum ship USS The Sullivans sank at her Pier in the Buffalo Naval Park. [1][2][3], Following World War II most of the class had their AA and anti-submarine warfare (ASW) armament upgraded. (later cancelled). who supplied us with this set of plans from the 1968 Charleston Navy Yard
31 vessels were authorized on 9 July 1942: 4 vessels were authorized on 13 May 1942: 3 vessels were authorized on 27 March 1943 under the VinsonTrammell Act: 114 vessels were authorized on 19 July 1943 under the 70% Expansion Act: (Of the missing numbers in this sequence - 722 to 741, 744 to 762, 770 to 781, and 857 were allocated to orders for Allen M.

[12], An upgraded version of DASH, QH-50D, remained in use by the United States Army until May 2006. 26 ships (DD-742-745, 805-808, 829-835, and 873-883) were ordered without torpedo tubes to allow for radar picket equipment; these were redesignated as DDRs in 1948. Nine ships were converted to escort destroyers (DDE), emphasizing ASW. (later cancelled), DD-909 to DD-916 awarded to Bethlehem Steel, Staten Island. The Allen M. Sumner class was a group of 58 destroyers built by the United States during World War II.Another twelve ships were completed as destroyer minelayers.The class was named for Allen Melancthon Sumner, an officer in the United States Marine Corps.Often referred to as simply the Sumner, this class was distinguished from the previous Fletcher class by their twin 5-inch/38 caliber gun .

In 1945 the first warship named after a woman by US Navy entered combat. Nine more unnamed vessels (DD-896 to DD-904) awarded to Bath Iron Works, and another eight (DD-909 to DD-916) awarded to Bethlehem at Staten Island, were all cancelled on 28 March 1945. The second twin 5" gun mount and all previous AA guns and ASW equipment were removed. Once you have approved your model, well collect the final balance and she will be shipped in a robust shipping crate and insured for your protection. FRAM II ships included six DDRs and six DDEs that retained their specialized equipment (196061), as well as four DDRs that were converted to DDs and were nearly identical to the Allen M. Sumner class FRAM IIs (196263). The DASH ASW drones were not acquired, but hangar facilities aboard those ships that had them were later used to accommodate ASW versions of MD 500 Defender helicopters. Destroyer conversions relied on experience with Fletcher-class destroyers modernized for transfer to Spain and Germany in 1957. Main gun armament was five dual-purpose 5-inch/38 caliber (127mm) 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. development of Scheme "B-II" of 30 September 1941, and was the basis

Three (Pringle, Stevens and Halford) were built with aircraft catapults after deletion of the rear torpedo tube mount and the number 3 5-inch gun mount. shows the template . USS Carpenter (DD-825) was the most thorough DDE conversion, with 4 3"/70cal guns in twin enclosed mounts, two Weapon Alpha launchers, four new 21" torpedo tubes for the Mark 37 ASW torpedo, and one depth charge rack.[4]. weapon of the original Fletchers). Nine ships were converted to escort destroyers (DDE), emphasizing ASW. Shop products from small business brands sold in Amazons store. As designed, the Gearings' armament was identical to the Sumners'. Lacking ASROC, the FRAM II ships were disposed of in 1969-74. Both the Mk 32 torpedo tubes and ASROC launched Mk. Price and other details may vary based on product size and color. The hull was lengthened 14 ft (4.3 m) amidships, creating more storage space for fuel, thus giving the ships a longer range than the Sumner s. Sonar Installation, 1951 BuShips Grebe Missile

Twelve of the first thirteen ships to complete (DDs 7423, 8058, 829 and 87377) were selected in January; twelve more (DDs 83035 and 87883) in May. However, the date of termination of the SUM-N-2 program is
Others carried trainable Hedgehogs. DD-805 to DD-808 awarded to Bath Iron Works, Bath, Maine. Transferred to Republic of China, 1 October 1977 and become museum at An-Pin harbor TAI-NAN, TAIWAN. Under the most advanced Wu Chin III upgrade program, all World War II vintage weapons were removed and replaced with four Hsiung Feng II surface-to-surface missiles, ten SM-1 (box launchers), one 8-cell ASROC, one Otobreda 76 mm (3 in) gun, two Bofors 40 mm (1.6 in)/70 AA, one 20 mm Phalanx CIWS and two triple 12.75 in (324 mm) torpedo tubes.

Some naval historians will tell you that the Fletcher class destroyer was the most successful ship of World War 2, and that the war would not have been won without them. 2013. Velos alongside G. Averof are ceremonially commissioned by the Hellenic Navy having Palaio Faliro as their base. During this era the ASROC system had an effective range of only 5 nautical miles (9.3km; 5.8mi), but the DASH drone allowed the ship to deploy ASW attack to sonar contacts as far as 22nmi (41km; 25mi) away. content are herein copyrighted and owned exclusively by Gyrodyne Helicopter
Since then, the ship has been refloated and restoration of the ship's electric system and interior spaces is ongoing.[28]. Both the Mk 32 torpedo tubes and ASROC launched Mk. This fire control system provided effective long-range anti-aircraft (AA) or anti-surface fire. } [citation needed], The Gyrodyne QH-50C DASH was an unmanned anti-submarine helicopter, controlled remotely from the ship. DD-851 to DD-853 awarded to Bethlehem Steel, Fore River Shipyard, Quincy. The FRAM II program was designed primarily for the Sumner-class destroyers, but sixteen Gearings were upgraded as well. Other notable changes are a modified bridge arrangement and two twin 40mm

31 vessels were authorised on 9 July 1942: 4 vessels were authorised on 13 May 1942: 3 vessels were authorised on 27 March 1943 under the Vincent-Trammell Act: 118 vessels were authorised on 19 July 1943 under the 70% Expansion Act: (Of the missing numbers in this sequence - 722 to 741, 744 to 762, 770 to 781, and 857 were allocated to orders for Allen M.

In combat, commanders often requisitioned additional guns with some ships mounting up to thirteen 20mm cannons. [7] The answer that came back was that five 5in (127mm) 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.

As of April 2012 two were laid up in non-operational condition in Kaohsiung, Taiwan: ROCS Chien Yang (DDG-912), formerly USSJames E. Kyes(DD-787) and ROCS Sheng Yang (DDG-923), formerly USSPower(DD-839). As the threat from kamikaze aircraft mounted in 1945, and with few remaining Japanese warships to use torpedoes on, most of the class had the aft quintuple 21-inch (533 mm) torpedo tube mount replaced by an additional 40 mm quadruple mount (prior to completion on later ships) for 16 total 40 mm guns. Two (Bath Iron Works Frank Knox and Southerland, numbered in sequence and launched without pause in the production schedule after Drexler, the yards last Sumner) commissioned in 1944. These had the same ASW armament as a Gearing FRAM destroyer, with the addition of improved sonar and a piloted helicopter, initially the Kaman SH-2 Seasprite and from 1984 the Sikorsky SH-60 Seahawk. The main difference was that the Gearings were 14 feet (4.3 m) longer in the midship section, allowing for increased fuel tankage for greater range, an important consideration in Pacific War operations. Army's past use of DASH. The Gearing design was similar to the Sumner class but with a longer hull length of 14 feet to allow for additional fuel (giving the ship a longer range than the Sumner class) and other upgrades including AA armament . // -->
