Lockheed P-2 Neptune (Greenwood)
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 (using JATO assist), 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
VP-56
VP-56, nicknamed the ''Dragons'', was a long-lived Patrol Squadron of the U.S. Navy. It was originally established as Patrol Squadron VP-900 on 1 July 1946, redesignated Medium Patrol Squadron (Landplane) VP-ML-71 on 15 November 1946, redesignated VP-661 in February 1950, redesignated VP-56 on 4 February 1953 and disestablished on 28 June 1991. It was the second squadron to be designated VP-56, the first VP-56 was redesignated OTS on 1 July 1941. Operational history *1 July 1946: VP-900 was established at NAS Anacostia, Washington D.C. It came under the operational control of FAW-5 and administrative control of the Naval Air Reserve Training Command. The squadron was one of 21 naval reserve squadrons established after the war to accommodate the large number of aircrews recently released from active duty and utilize the enormous stocks of aircraft on the inventory. The squadron flew the PBY-5A/6A Catalina amphibian and the PV-2 Harpoon landplane. *15 November 1946: All patrol ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Letter Of Intent
A letter of intent (LOI or LoI, or Letter of Intent) is a document outlining the understanding between two or more parties which they intend to formalize in a contract, legally binding agreement. The concept is similar to a Heads of agreement (law), heads of agreement, term sheet or memorandum of understanding. Merger and acquisition agreements, joint venture agreements, real property lease agreements and several other categories of agreements often make use of a letter of intent. The capitalized form ''Letter of Intent'' may be used in legal writing, but only when referring to a specific document under discussion. LOIs resemble short, written contracts, often in tabular form. They are not binding on the parties in their entirety. Many LOIs, however, contain provisions that are binding, such as those governing non-disclosure agreement, non-disclosure, governing law, Exclusive exclusivity or a Covenant (law), covenant to negotiate in good faith. A LOI may sometimes be interprete ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

AN/APS-20
The AN/APS-20 was an airborne early warning, anti-submarine, maritime surveillance and weather radar developed in the United States in the 1940s. Entering service in 1945, it served for nearly half a century, finally being retired in 1991. Initially developed at Massachusetts Institute of Technology (MIT) under ''Project Cadillac'', the radar was developed to be carried by aircraft to extend the sensor range of ships by placing a radar at altitude. Although developed for carrier-borne operation, first being installed in the single-engined General Motors TBM-3W Avenger, it was also used in larger four-engined airframes, the last being a fleet of Avro Shackleton AEW.2 which were converted from maritime patrol aircraft. Similarly, although developed for detecting aircraft, it saw extensive service in anti-submarine and maritime patrol roles and was one of the first radars to be used in researching extreme weather like hurricanes by agencies like the Environmental Science Services Ad ...

Magnetic Anomaly Detector
A magnetic anomaly detector (MAD) is an instrument used to detect minute variations in the Earth's magnetic field. The term refers specifically to magnetometers used by military forces to detect submarines (a mass of ferromagnetic material creates a detectable disturbance in the magnetic field); military MAD equipment is a descendant of geomagnetic survey or aeromagnetic survey instruments used to search for minerals by detecting their disturbance of the normal earth-field. History Geoexploration by measuring and studying variations in the Earth's magnetic field has been conducted by scientists since 1843. The first uses of magnetometers were for the location of ore deposits. Thalen's "The Examination of Iron Ore Deposits by Magnetic Measurements", published in 1879, was the first scientific treatise describing this practical use. Magnetic anomaly detectors employed to detect submarines during World War II harnessed the fluxgate magnetometer, an inexpensive and easy to use t ...

Sonobuoy
A sonobuoy (a portmanteau of sonar and buoy) is a relatively small buoy – typically diameter and long – expendable sonar system that is dropped/ejected from aircraft or ships conducting anti-submarine warfare or underwater acoustic research. Theory of operation Sonobuoys are ejected from aircraft in canisters and deploy upon water impact. An inflatable surface float with a radio transmitter remains on the surface for communication with the aircraft, while one or more hydrophone sensors and stabilizing equipment descend below the surface to a selected depth that is variable, depending on environmental conditions and the search pattern. The buoy relays acoustic information from its hydrophone(s) via UHF/ VHF radio to operators on board the aircraft. History With the technological improvement of the submarine in modern warfare, the need for an effective tracking system was born. Sound Navigation And Ranging (SONAR) was originally developed by the British—who cal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Destroyer
In naval terminology, a destroyer is a fast, manoeuvrable, long-endurance warship intended to escort larger vessels in a fleet, convoy or battle group and defend them against powerful short range attackers. They were originally developed in 1885 by Fernando Villaamil for the Spanish NavySmith, Charles Edgar: ''A short history of naval and marine engineering.'' Babcock & Wilcox, ltd. at the University Press, 1937, page 263 as a defense against torpedo boats, and by the time of the Russo-Japanese War in 1904, these "torpedo boat destroyers" (TBDs) were "large, swift, and powerfully armed torpedo boats designed to destroy other torpedo boats". Although the term "destroyer" had been used interchangeably with "TBD" and "torpedo boat destroyer" by navies since 1892, the term "torpedo boat destroyer" had been generally shortened to simply "destroyer" by nearly all navies by the First World War. Before World War II, destroyers were light vessels with little endurance for unattended o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
P-3 Orion
The Lockheed P-3 Orion is a four-engined, turboprop anti-submarine and maritime surveillance aircraft developed for the United States Navy and introduced in the 1960s. Lockheed based it on the L-188 Electra commercial airliner. The aircraft is easily distinguished from the Electra by its distinctive tail stinger or "MAD" boom, used for the (MAD) of submarines. Over the years, the aircraft has seen numerous design developments, most notably in its electronics packages. Nume ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Westinghouse J34
The Westinghouse J34, company designation Westinghouse 24C, was a turbojet engine developed by Westinghouse Aviation Gas Turbine Division in the late 1940s. Essentially an enlarged version of the earlier Westinghouse J30, the J34 produced 3,000 pounds of thrust, twice as much as the J30. Later models produced as much as 4,900 lb with the addition of an afterburner. It first flew in 1947. The J46 engine was developed as a larger, more powerful version of Westinghouse's J34 engine, about 50% larger. Development Built in an era of rapidly advancing gas turbine engine technology, the J34 was largely obsolete before it saw service, and often served as an interim engine. For instance, the Douglas X-3 Stiletto was equipped with two J34 engines when the intended Westinghouse J46 engine proved to be unsuitable. The Stiletto was developed to investigate the design of an aircraft at sustained supersonic speeds. However, equipped with the J34 instead of its intended engines, it was ser ...

Avro Shackleton
The Avro Shackleton is a British long-range maritime patrol aircraft (MPA) which was used by the Royal Air Force (RAF) and the South African Air Force (SAAF). It was developed by Avro from the Avro Lincoln bomber, which itself had been a development of the famous wartime Avro Lancaster bomber. The Shackleton was developed during the late 1940s as part of Britain's military response to the rapid expansion of the Soviet Navy, in particular its submarine force. Produced as the primary type equipping RAF Coastal Command, the ''Type 696'', as it was initially designated, incorporated major elements of the Lincoln, as well as the Avro Tudor passenger aircraft, and was furnished with extensive electronics suites in order to perform the anti-submarine warfare (ASW) mission along with a much-improved crew environment to accommodate the long mission times involved in patrol work. Being known for a short time as the ''Lincoln ASR.3'', it was decided that the Type 696 would be named ''Sh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
North American AJ Savage
The North American AJ Savage (later A-2 Savage) is an American carrier-based aircraft, carrier-based medium bomber built for the United States Navy by North American Aviation. The aircraft was designed shortly after World War II to carry atomic bombs and this meant that the bomber was the heaviest aircraft thus far designed to operate from an aircraft carrier. It was powered by two piston engines and a turbojet buried in the rear fuselage. The AJ-1 first became operational in 1950 and several were based in South Korea during 1953 as a deterrent against North Korea. Of the 140 built, plus three prototypes, 30 were reconnaissance aircraft. Aerial refueling, Inflight-refueling equipment was deployed on the Savage in the mid-1950s. The bomber was replaced by the Douglas A3D Skywarrior beginning in 1957. Design and development At the end of World War II, the U.S. Navy began a design competition on 13 August 1945 for a carrier-based bomber which could carry a bomb that was won by Nor ...
