P4M Mercator
The Martin P4M Mercator was a maritime reconnaissance aircraft built by the Glenn L. Martin Company. The Mercator was an unsuccessful contender for a United States Navy requirement for a long-range maritime patrol bomber, with the Lockheed P2V Neptune chosen instead. It saw a limited life as a long-range electronic reconnaissance aircraft. Its most unusual feature was that it was powered by a combination of piston engines and turbojets, the latter being in the rear of the engine nacelles. Design and development Work began on the Model 219 in 1944, as a replacement for the PB4Y Privateer long-range patrol bomber, optimised for long range minelaying missions, with the first flight being on 20 October 1946.Lake and Dorr 2000, p.139. A large and complicated aircraft, it was powered by two Pratt & Whitney R4360 Wasp Major 28-cylinder radial engines. To give a boost during takeoff and combat, two Allison J33 turbojets were fitted in the rear of the two enlarged engine nacelles, th ...

WikiProject Aircraft
A WikiProject, or Wikiproject, is a Wikimedia movement affinity group for contributors with shared goals. WikiProjects are prevalent within the largest wiki, Wikipedia, and exist to varying degrees within Wikimedia project, sister projects such as Wiktionary, Wikiquote, Wikidata, and Wikisource. They also exist in different languages, and translation of articles is a form of their collaboration. During the COVID-19 pandemic, CBS News noted the role of Wikipedia's WikiProject Medicine in maintaining the accuracy of articles related to the disease. Another WikiProject that has drawn attention is WikiProject Women Scientists, which was profiled by ''Smithsonian Magazine, Smithsonian'' for its efforts to improve coverage of women scientists which the profile noted had "helped increase the number of female scientists on Wikipedia from around 1,600 to over 5,000".

United States Military Aircraft Serials
In the United States, all military aircraft display a serial number to identify individual aircraft. These numbers are located on the aircraft tail, so they are sometimes referred to unofficially as "tail numbers". On the Northrop Grumman B-2 Spirit bomber, lacking a tail, the number appears on the nose gear door. Individual agencies have each evolved their own system of serial number identification. Aircraft serials are part of the Aircraft Visual Identification System, which also includes the aircraft's tail code and Modex. History United States Army Signal Corps In 1908, the United States government purchased its first heavier than air aircraft. The aircraft, a Wright Model A, was used by the aviation section of the United States Army Signal Corps and was issued with serial number 1. Subsequent aircraft were numbered in sequence. United States Army Air Service In 1918, the aviation section of the Army Air Service became the United States Army Air Service (USAAS), but the ...

VQ-1
Fleet Air Reconnaissance Squadron 1 (VQ-1) is an aviation unit of the United States Navy established on 1 June 1955. Its role is aerial reconnaissance and signals intelligence. The squadron is nicknamed the "World Watchers" and is based at NAS Whidbey Island, flying Lockheed EP-3E Aries II aircraft. Squadron History The lineage of VQ-1's "World Watchers" can be traced back to two PBY-5A Catalina "Black Cats" modified for electronic reconnaissance during World War II. The unit formally established as the Special Electronic Search Project at NAS Sangley Point, in October 1951. By 13 May 1953, when it was redesignated Detachment Able of Airborne Early Warning Squadron One (VW-1), the unit operated four P4M-1Q Mercators. 1950s When Detachment Able was reorganized into Electronic Countermeasures Squadron One (VQ-1) at Iwakuni, Japan on 1 June 1955, it was the first squadron dedicated to electronic warfare. The EA-3 Skywarrior served the squadron for the next three decades. 19 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Naval Air Station Atsugi
is a joint Japan-US naval air base located in the cities of Yamato and Ayase in Kanagawa, Japan. It is the largest United States Navy (USN) air base in the Pacific Ocean and once housed the squadrons of Carrier Air Wing Five (CVW-5), which deploys with the aircraft carrier . During 2017 and 2018 the fixed-wing aircraft of CVW-5 relocated to Marine Corps Air Station Iwakuni in western Japan. CVW-5 shares the base with the Headquarters Fleet Air Force and Fleet Air Wing 4 of the Japan Maritime Self-Defense Force (JMSDF). NAF Atsugi is also home to Helicopter Maritime Strike Squadron 51 ( HSM-51), which provides detachments of MH-60R helicopters to forward deployed U.S. Navy guided missile cruisers, guided missile destroyers and frigates homeported at the nearby Yokosuka Naval Base. Service members stationed at Atsugi also work in conjunction with the former Kamiseya Naval Radio Receiving Facility. Despite its name, the base is east northeast from the city of Atsugi, and ...

Naval Air Station Iwakuni
A navy, naval force, or maritime force is the branch of a nation's armed forces principally designated for naval warfare, naval and amphibious warfare; namely, lake-borne, riverine, littoral zone, littoral, or ocean-borne combat operations and related functions. It includes anything conducted by surface Naval ship, ships, amphibious warfare, amphibious ships, submarines, and seaborne naval aviation, aviation, as well as ancillary support, communications, training, and other fields. The strategic offensive role of a navy is Power projection, projection of force into areas beyond a country's shores (for example, to protect Sea lane, sea-lanes, deter or confront piracy, ferry troops, or attack other navies, ports, or shore installations). The strategic defensive purpose of a navy is to frustrate seaborne projection-of-force by enemies. The strategic task of the navy also may incorporate nuclear deterrence by use of submarine-launched ballistic missiles. Naval operations can be broa ...

PB4Y-2 Privateer
The Consolidated PB4Y-2 Privateer is an American World War II and Korean War era patrol bomber of the United States Navy derived from the Consolidated B-24 Liberator. The Navy had been using B-24s with only minor modifications as the PB4Y-1 Liberator, and along with maritime patrol Liberators used by RAF Coastal Command this type of patrol plane was proven successful. A fully navalised design was desired, and Consolidated developed a dedicated long- range patrol bomber in 1943, designated PB4Y-2 Privateer.Baugher, Joe"Convair PB4Y-2 Privateer."''American Military Aircraft,'' 23 August 1999. Retrieved: 13 November 2010. In 1951, the type was redesignated P4Y-2 Privateer. A further designation change occurred in September 1962, when the remaining Navy Privateers (all having previously been converted to drone configuration as P4Y-2K) were redesignated QP-4B. Design and development The Privateer was externally similar to the Liberator, but the fuselage was longer to accommodate a ...

SIGINT
Signals intelligence (SIGINT) is intelligence-gathering by interception of '' signals'', whether communications between people (communications intelligence—abbreviated to COMINT) or from electronic signals not directly used in communication (electronic intelligence—abbreviated to ELINT). Signals intelligence is a subset of intelligence collection management. As classified and sensitive information is usually encrypted, signals intelligence in turn involves the use of cryptanalysis to decipher the messages. Traffic analysis—the study of who is signaling whom and in what quantity—is also used to integrate information again. History Origins Electronic interceptions appeared as early as 1900, during the Boer War of 1899–1902. The British Royal Navy had installed wireless sets produced by Marconi on board their ships in the late 1890s, and the British Army used some limited wireless signalling. The Boers captured some wireless sets and used them to make vital transm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
