AQM-41 Petrel
The AUM-N-2 Petrel, also known as Kingfisher C and AUM-2, was an air-to-surface missile produced as part of Project Kingfisher for the United States Navy. Intended for use against enemy surface ships and surfaced submarines, giving aircraft the ability to deliver aerial torpedoes from outside the range of defensive armament, it saw brief operational service in the late 1950s. The project was never considered a high priority by the Navy however, as it was useless against submerged submarines, which were considered the greatest potential threat. Following its withdrawal from operational usage, the Petrel was used as a target drone, receiving the designation AQM-41A shortly before being retired from service altogether. Design and development The development of the Petrel began in August 1944, when the U.S. Navy Bureau of Ordnance (BuOrd) began Project Kingfisher, intending to develop a series of standoff torpedo weapons. The "Kingfisher C", later designated AUM-2 and then as AUM-N ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lockheed P-2 Neptune
The Lockheed P-2 Neptune (designated P2V by the United States Navy prior to September 1962) is a maritime patrol and anti-submarine warfare (ASW) aircraft. It was developed for the US Navy by Lockheed to replace the Lockheed PV-1 Ventura and PV-2 Harpoon, and was replaced in turn by the Lockheed P-3 Orion. Designed as a land-based aircraft, the Neptune never made a carrier landing, but a small number were converted and deployed as carrier-launched, stop-gap nuclear bombers that would have to land on shore or ditch. The type was successful in export, and saw service with several armed forces. Design and development Development of a new land-based patrol bomber began early in World War II, with design work starting at Lockheed's Vega subsidiary as a private venture on 6 December 1941.Scutts ''Air International'' January 1995, pp. 42–43. At first, the new design was considered a low priority compared to other aircraft in development at the time, with Vega also developing and ...

Mach Number
Mach number (M or Ma) (; ) is a dimensionless quantity in fluid dynamics representing the ratio of flow velocity past a boundary to the local speed of sound. It is named after the Moravian physicist and philosopher Ernst Mach. : \mathrm = \frac, where: : is the local Mach number, : is the local flow velocity with respect to the boundaries (either internal, such as an object immersed in the flow, or external, like a channel), and : is the speed of sound in the medium, which in air varies with the square root of the thermodynamic temperature. By definition, at Mach1, the local flow velocity is equal to the speed of sound. At Mach0.65, is 65% of the speed of sound (subsonic), and, at Mach1.35, is 35% faster than the speed of sound (supersonic). Pilots of high-altitude aerospace vehicles use flight Mach number to express a vehicle's true airspeed, but the flow field around a vehicle varies in three dimensions, with corresponding variations in local Mach number. The local spe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1962 United States Tri-Service Missile And Drone Designation System
In 1963, the U.S. Department of Defense established a designation system for rockets and guided missiles jointly used by all the United States armed services. It superseded the separate designation systems the Air Force and Navy had for designating US guided missiles and drones, but also a short-lived interim USAF system for guided missiles and rockets. History On 11 December 1962, the U.S. Department of Defense issued Directive 4000.20 “Designating, Redesignating, and Naming Military Rockets and Guided Missiles” which called for a joint designation system for rockets and missiles which was to be used by all armed forces services. The directive was implemented via Air Force Regulation (AFR) 66-20, Army Regulation (AR) 705-36, Bureau of Weapons Instruction (BUWEPSINST) 8800.2 on 27 June 1963. A subsequent directive, DoD Directive 4120.15 "Designating and Naming Military Aircraft, Rockets, and Guided Missiles", was issued on 24 November 1971 and implemented via Air Force Regulatio ...

United States Navy Reserve
The United States Navy Reserve (USNR), known as the United States Naval Reserve from 1915 to 2005, is the Reserve Component (RC) of the United States Navy. Members of the Navy Reserve, called Reservists, are categorized as being in either the Selected Reserve (SELRES), the Training and Administration of the Reserve (TAR), the Individual Ready Reserve (IRR), or the Retired Reserve. Organization The mission of the Navy Reserve is to provide strategic depth and deliver operational capabilities to the Navy and Marine Corps team, and to the Joint forces, in the full range of military operations from peace to war. The Navy Reserve consists of 59,152 officers and enlisted personnel who serve in every state and territory as well as overseas as of September 2020. Selected Reserve (SELRES) The largest cohort, the Selected Reserve (SELRES), have traditionally drilled one weekend a month and performed two weeks of active duty annual training during the year, receiving base pay and certa ...

VP-17
VP-17, nicknamed the ''White Lightnings'', was a Patrol Squadron of the U.S. Navy. The squadron was established as Reserve Patrol Squadron VP-916 on 1 July 1946. It was redesignated as Medium Patrol Squadron VP-ML-66 on 15 November 1946, as VP-722 in February 1950, and as VP-17 on 4 February 1953. It was redesignated Heavy Attack Mining Squadron VA-(HM)-10 on 1 July 1956, and finally, for the second time, redesignated VP-17 on 1 July 1959. The squadron was disestablished on 31 March 1995, after 49 years of service. It was the third squadron to be designated VP-17, the first VP-17 was redesignated as VP-42 on 1 July 1939 and the second VP-17 was redesignated VPB-17 on 1 October 1944. Operational history * May 1946: VP-916 was established at NAS Los Alamitos, California. The squadron came under the operational control of FAW-4 and administrative control by Naval Air Reserve Training (NARTU). It was another of the 21 naval reserve squadrons established after the war to accommod ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Wyandanch
Wyandanch (, ) is a hamlet and census-designated place (CDP) in the Town of Babylon in Suffolk County, New York. The population was 12,990 at the 2020 census. In the past, some or all of Wyandanch was proposed to become part of the never-realized Incorporated Village of Half Hollow Hills and later on proposed incorporating itself as the Incorporated Village of Wyandanch. However, those plans failed and Wyandanch has never been incorporated. History Native settlement This hamlet is named after Chief Wyandanch, a leader of the Montaukett Native American tribe during the 17th century. Formerly known as Half Way Hollow Hills, West Deer Park (1875), and Wyandance (1893), the area of scrub oak and pine barrens south of the southern slope of Half Hollow terminal moraine was named Wyandanch in 1903 by the Long Island Rail Road (LIRR) to honor Chief Wyandanch and end confusion between travelers getting off at the West Deer Park and Deer Park railroad stations.

Grumman S2F Tracker
The Grumman S-2 Tracker (S2F prior to 1962) was the first purpose-built, single airframe anti-submarine warfare (ASW) aircraft to enter service with the United States Navy. Designed and initially built by Grumman, the Tracker was of conventional design — propeller-driven with twin radial engines, a high wing that could be folded for storage on aircraft carriers, and tricycle undercarriage. The type was exported to a number of navies around the world. Introduced in 1952, the Tracker and its Grumman E-1 Tracer, E-1 Tracer derivative saw service in the U.S. Navy until the mid-1970s, and its Grumman C-1 Trader, C-1 Trader derivative until the mid-1980s, with a few aircraft remaining in service with other air arms into the 21st century. Argentina and Brazil are the last countries to still use the Tracker. Design and development The Tracker was intended as a replacement for the Grumman AF Guardian, which was the first purpose-built aircraft system for ASW, using two airframes ...
