427th Reconnaissance Squadron
The 427th Reconnaissance Squadron is an active United States Air Force (USAF) unit assigned to Beale Air Force Base, California. The squadron's roots go back to World War I, when it was organized as the 38th Aero Squadron, a training unit that served in Texas and Illinois. When the United States Army Air Service reorganized its training units in July 1918, the squadron was renamed Squadron A, Chanute Field. Following the Armistice of 11 November 1918, the squadron was demobilized in December. The World War I squadron was consolidated with the 38th Pursuit Squadron when that unit was activated in 1933, although it was not equipped before it was inactivated in 1935. The squadron was activated again in 1936 as the 38th Reconnaissance Squadron, forming the long range reconnaissance arm of the 1st Wing. The squadron was attached to the 19th Bombardment Group and began its deployment to join the group in the Philippines in December 1941. However, the 38th's Boeing B-17 Flying Fortre ...

Aerial Reconnaissance
Aerial reconnaissance is reconnaissance for a military or strategic purpose that is conducted using reconnaissance aircraft. The role of reconnaissance can fulfil a variety of requirements including artillery spotting, the collection of imagery intelligence, and the observation of enemy maneuvers. History Early developments After the French Revolution, the new rulers became interested in using the balloon to observe enemy manoeuvres and appointed scientist Charles Coutelle to conduct studies using the balloon ''L'Entreprenant'', the first military reconnaissance aircraft. The balloon found its first use in the 1794 conflict with Austria, where in the Battle of Fleurus they gathered information. Moreover, the presence of the balloon had a demoralizing effect on the Austrian troops, which improved the likelihood of victory for the French troops. To operate such balloons, a new unit of the French military, the French Aerostatic Corps, was established; this organisatio ...

Northrop Grumman RQ-180
The Northrop Grumman RQ-180 is an American stealth unmanned aerial vehicle (UAV) surveillance aircraft intended for contested airspace. , there had been no images or statements released, but growing evidence points to the existence of the RQ-180 and its use in regular front-line service. Development After the retirement of the SR-71 Blackbird in 1999, the US Air Force lacked an intelligence platform capable of penetrating airspace guarded by advanced air defense systems. The RQ-180 was designed to fulfill the mission previously accomplished by the high-speed SR-71. The RQ-180 appears to be a follow-on to the Joint Unmanned Combat Air Systems project which was cancelled in late 2005 when the United States Navy (USN) wanted a carrier-based aircraft (which led to the UCAS-D) while the United States Air Force (USAF) wanted a larger, long-range global strike platform. In December 2005, the program was split in two, with the USN starting the UCAS-D program which created the Northrop ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United States Army
The United States Army (USA) is the land service branch of the United States Armed Forces.

MC-12 Liberty
The Beechcraft C-12 Huron is the military designation for a series of twin-engine turboprop aircraft based on the Beechcraft Super King Air and Beechcraft 1900. C-12 variants are used by the United States Air Force, United States Army, United States Navy and United States Marine Corps. These aircraft are used for various duties, including embassy support, medical evacuation, as well as passenger and light cargo transport. Some aircraft are modified with surveillance systems for various missions, including the Cefly Lancer, Beechcraft RC-12 Guardrail and Project Liberty programs. Design and development The first C-12A models entered service with the U.S. Army in 1974 and were used as a liaison and general personnel transport. The aircraft was essentially an "off-the-shelf" Super King Air 200, powered by the type's standard Pratt & Whitney Canada PT6A-41 engines. The U.S. Navy followed suit in 1979, ordering a version of the Super King Air A200C (modified with a 1.32 m by 1.32 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
9th Operations Group
The 9th Operations Group is the operational flying component of the 9th Reconnaissance Wing, stationed at Beale Air Force Base, California.

Boeing B-47 Stratojet
The Boeing B-47 Stratojet (Boeing company designation Model 450) is a retired American long-range, six-engined, turbojet-powered strategic bomber designed to fly at high subsonic speed and at high altitude to avoid enemy interceptor aircraft. The primary mission of the B-47 was as a nuclear bomber capable of striking targets within the Soviet Union. Development of the B-47 can be traced back to a requirement expressed by the United States Army Air Forces (USAAF) in 1943 for a reconnaissance bomber that harnessed newly developed jet propulsion. Another key innovation adopted during the development process was the swept wing, drawing upon captured German research. With its engines carried in nacelles underneath the wing, the B-47 represented a major innovation in post-World War II combat jet design, and contributed to the development of modern jet airliners. Suitably impressed, in April 1946, the USAAF ordered two prototypes, designated "XB-47"; on 17 December 1947, the first ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

303d Bombardment Group
3 (three) is a number, numeral and digit. It is the natural number following 2 and preceding 4, and is the smallest odd prime number and the only prime preceding a square number. It has religious or cultural significance in many societies. Evolution of the Arabic digit The use of three lines to denote the number 3 occurred in many writing systems, including some (like Roman and Chinese numerals) that are still in use. That was also the original representation of 3 in the Brahmic (Indian) numerical notation, its earliest forms aligned vertically. However, during the Gupta Empire the sign was modified by the addition of a curve on each line. The Nāgarī script rotated the lines clockwise, so they appeared horizontally, and ended each line with a short downward stroke on the right. In cursive script, the three strokes were eventually connected to form a glyph resembling a with an additional stroke at the bottom: ३. The Indian digits spread to the Caliphate in the 9th ...

Imperial Japanese Naval Air Service
The was the air arm of the Imperial Japanese Navy (IJN). The organization was responsible for the operation of naval aircraft and the conduct of aerial warfare in the Pacific War. The Japanese military acquired their first aircraft in 1910 and followed the development of air combat during World War I with great interest. They initially procured European aircraft but quickly built their own and launched themselves onto an ambitious aircraft carrier building program. They launched the world's first purpose-built aircraft carrier, , in 1922. Afterwards they embarked on a conversion program of several excess battlecruisers and battleships into aircraft carriers. The IJN Air Service had the mission of national air defence, deep strike, naval warfare, and so forth. It retained this mission to the end. The Japanese pilot training program was very selective and rigorous, producing a high-quality and long-serving pilot corps, who were very successful in the air during the early ...
