Signals Intelligence
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 transmis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Military Units And Formations Of The Royal Australian Air Force In World War II
A military, also known collectively as armed forces, is a heavily armed, highly organized force primarily intended for warfare. It is typically authorized and maintained by a sovereign state, with its members identifiable by their distinct military uniform. It may consist of one or more military branches such as an army, navy, air force, space force, marines, or coast guard. The main task of the military is usually defined as defence of the state and its interests against external armed threats. In broad usage, the terms ''armed forces'' and ''military'' are often treated as synonymous, although in technical usage a distinction is sometimes made in which a country's armed forces may include both its military and other paramilitary forces. There are various forms of irregular military forces, not belonging to a recognized state; though they share many attributes with regular military forces, they are less often referred to as simply ''military''. A nation's military may f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lockheed Model 10 Electra
The Lockheed Model 10 Electra is an American twin-engined, all-metal monoplane airliner developed by the Lockheed Aircraft Corporation in the 1930s to compete with the Boeing 247 and Douglas DC-2. The type gained considerable fame as one was flown by Amelia Earhart on her ill-fated around-the-world expedition in 1937. Design and development Some of Lockheed's wooden designs, such as the Orion, had been built by Detroit Aircraft Corporation with metal fuselages. However, the Electra was Lockheed's first all-metal and twin-engined design by Lloyd Stearman and Hall Hibbard. The name Electra came from a star in the Pleiades. The prototype made its first flight on February 23, 1934, with Marshall Headle at the controls. Wind-tunnel work on the Electra was undertaken at the University of Michigan. Much of the work was performed by a student assistant, Clarence Johnson. He suggested two changes be made to the design: changing the single tail to double tails (later a Lockheed trade ...

Mitsubishi G4M
The Mitsubishi G4M was a twin-engine, land-based medium bomber formerly manufactured by the Mitsubishi Aircraft Company, a part of Mitsubishi Heavy Industries, and operated by the Imperial Japanese Navy from 1940 to 1945. Its official designation is and was commonly referred to by Japanese Navy pilots as due to the cylindrical shape of its fuselage and its penchant for igniting after a hit. The Allied reporting name was "Betty". Designed to a strict specification to succeed the Mitsubishi G3M already in service, the G4M boasted very good performance and excellent range and was considered the best land-based naval bomber at the time. This was achieved by its structural lightness and an almost total lack of protection for the crew, with no armor plating or self-sealing fuel tanks. The G4M was officially adopted on 2 April 1941 but the aforementioned problems would prove to be a severe drawback, often suffering heavy losses; Allied fighter pilots nicknamed the G4M "The Flying L ...

De Havilland Dragon Rapide
The de Havilland DH.89 Dragon Rapide is a 1930s short-haul biplane airliner developed and produced by British aircraft company de Havilland. Capable of accommodating 6–8 passengers, it proved an economical and durable craft, despite its relatively primitive plywood construction.
