The result was so effective that a further eleven were converted in 19523. Defense Station, 1959's FRAM II Each model is exquisitely crafted by our master model builders and comes fully assembled with a solid hull - hand carved from kiln-dried mahogany. This led to shift to the LAMPS program of manned helicopters, which the Gearing class were too small to accommodate. 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. As designed, the Gearings' armament was identical to that on the Allen M. Sumner class. been 3"/70s and MK108 Rocket Launchers. The hull was lengthened 14ft (4.3m) amidships, creating more storage space for fuel, thus giving the ships a larger range than the Sumners. Three are in the United States and one is in Greece, although only Kidd retains her World War II configuration. original Fletchers). BuShips - August 20, 1947, This is a large image, note the main armament would have Nine additional (for a total of 35) ships were converted to radar picket destroyers (DDR) in the early 1950s; these typically received only one 3-inch twin mount to save weight for radar equipment, as did the wartime radar pickets. The Grebe was part of the Kingfisher family of guided anti-ship/anti-submarine weapons, which was developed under the prime contract of the National Bureau of Standards (NBS). 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 . The 40mm and 20mm guns were replaced by two to six 3-inch (76mm)/50 caliber guns in up to two twin and two single mountings. By 1970, DASH had been withdrawn from FRAM I ships, though it was retained into the early 1970s on FRAM II ships, which lacked ASROC. 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. Gearing class destroyer development chart.png 3,198 2,141; 250 KB. Price and other details may vary based on product size and color. Compared to earlier designs, the Fletchers were large, allowing them to adapt to evolving defensive priorities through the addition of two 40-millimetre (1.6in) Bofors quadruple mount AA guns as well as six 20mm (0.79in) Oerlikon dual AA gun positions. More importantly in the long run, the increased size of the Gearings made them much more suitable for upgrades than the Allen M. Sumners, as seen in the wartime radar picket subclass, the 1950s radar picket destroyer (DDR) and escort destroyer (DDE) conversions, and the Fleet Rehabilitation and Modernization (FRAM) conversions 1960-1965. Both the Mk 32 torpedo tubes and ASROC launched Mk 44 homing ASW torpedoes. // -->. [7][8][9], In Navy slang, the modified destroyers were called "FRAM cans", "can" being a contraction of "tin can", the slang term for a destroyer or destroyer escort. [12], An upgraded version of DASH, QH-50D, remained in use by the United States Army until May 2006. Group A ships also received two MK10/11 Hedgehogs fitted on each side of the bridge at the O-1 level and had the MK-32 triple torpedo launchers aft of the second stack. At that time many were sold to other nations, where they served many more years. Naval Historical Center Photo #: S-511-51-E. Scheme "B-III" DASH was withdrawn from ASW service in 1969, due to poor reliability. The FRAM II ships retained all six 5-inch guns, except the DDEs retained four 5-inch guns and a trainable Hedgehog in the No. Twelve 40mm (1.57in) Bofors guns in two quad and two twin mounts and 11 20mm (0.79in) Oerlikon cannons in single mounts were also equipped. (later cancelled). 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 76mm (3in) Otobreda gun, two Bofors 40mm AA, one 20 mm Phalanx CIWS and two triple 12.75in (324mm) torpedo tubes. & Compartment & Access - Inboard Profile, 1947 DD-692 Class Long 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 initial design retained the Sumners' heavy torpedo armament of 10 21" (533mm) tubes in two quintuple mounts, firing the Mark 15 torpedo. if(MSFPhover) { MSFPnav10n=MSFPpreload("_derived/destroyer_tenders.htm_cmp_clearday110_hbtn.gif"); MSFPnav10h=MSFPpreload("_derived/destroyer_tenders.htm_cmp_clearday110_hbtn_a.gif"); } form above, is the Trademark of and owned by the Gyrodyne Helicopter Historical Displacement 3460 Tons (Full), Dimensions, 390' 6" (oa) x 40' 10" x 14' 4" (Max) Armament 6 x 5"/38AA (3x2), 12 x 40mm AA, 11 x 20mm AA, 10 x 21" tt.

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. Preliminary design plan prepared for the General Board near the end of the The first two destroyers began FRAM in Boston, Massachusetts and Long Beach, California shipyards in March 1959.
