Great Lakes BG
The Great Lakes BG was an American carrier-based dive bomber of the 1930s. Designed and built by the Great Lakes Aircraft Company of Cleveland, Ohio, 61 were used by the United States Navy and United States Marine Corps from 1934 to 1940. Development and design The Great Lakes Aircraft Company, who had previously built 18 TG-1 and 32 TG-2 variants of the Martin T4M,Swanborough and Bowers 1976, p.312. received an order from the U.S. Navy for a prototype two seat dive bomber capable of carrying a 1,000 lb (454 kg) bomb in 1933.Swanborough and Bowers 1976, p.193. (This compared with contemporary Scout Bombers such as the Vought SBU and the Curtiss SBC Helldiver, also capable of dive bombing, which had bombloads of 500 lb (227 kg)). The resulting design was a single engined biplane with single bay, unequal span tapered wings and a fixed tailwheel undercarriage. The aircraft was powered by a Pratt & Whitney Twin Wasp Junior radial engine.Donald 1997, p.46 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dive-bomber
A dive bomber is a bomber aircraft that dives directly at its targets in order to provide greater accuracy for the bomb it drops. Diving towards the target simplifies the bomb's trajectory and allows the pilot to keep visual contact throughout the bomb run. This allows attacks on point targets and ships, which were difficult to attack with conventional level bombers, even ''en masse''. After World War II, the rise of precision-guided munitions and improved anti-aircraft defences—both fixed gunnery positions and fighter interception—led to a fundamental change in dive bombing. New weapons, such as rockets, allowed for better accuracy from smaller dive angles and from greater distances. They could be fitted to almost any aircraft, including fighters, improving their effectiveness without the inherent vulnerabilities of dive bombers, which needed air superiority to operate effectively. Method A dive bomber dives at a steep angle, normally between 45 and 60 degrees or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

M1919 Browning Machine Gun
The M1919 Browning is a .30 caliber medium machine gun that was widely used during the 20th century, especially during World War II, the Korean War, and the Vietnam War. The M1919 saw service as a light infantry, coaxial, mounted, aircraft, and anti-aircraft machine gun by the U.S. and many other countries. The M1919 was an air-cooled development of the standard US machine gun of World War I, the John M. Browning-designed water-cooled M1917. The emergence of general-purpose machine guns in the 1950s pushed the M1919 into secondary roles in many cases, especially after the arrival of the M60 in US Army service. The United States Navy also converted many to 7.62 mm NATO, and designated them Mk 21 Mod 0; they were commonly used on riverine craft in the 1960s and 1970s in Vietnam. Many NATO countries also converted their examples to 7.62 mm caliber, and these remained in service well into the 1990s, as well as up to the present day in some countries. Operation Loading The ...

Second VA-35 (U
The second (symbol: s) is the unit of time in the International System of Units (SI), historically defined as of a day – this factor derived from the division of the day first into 24 hours, then to 60 minutes and finally to 60 seconds each (24 × 60 × 60 = 86400). The current and formal definition in the International System of Units ( SI) is more precise:The second ..is defined by taking the fixed numerical value of the caesium frequency, Δ''ν''Cs, the unperturbed ground-state hyperfine transition frequency of the caesium 133 atom, to be when expressed in the unit Hz, which is equal to s−1. This current definition was adopted in 1967 when it became feasible to define the second based on fundamental properties of nature with caesium clocks. Because the speed of Earth's rotation varies and is slowing ever so slightly, a leap second is added at irregular intervals to civil time to keep clocks in sync with Earth's rotation. Uses Analog clocks and watches often ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
VMA-231
Marine Attack Squadron 231 (VMA-231) is a United States Marine Corps fixed wing attack squadron that consists of AV-8B Harrier (V/STOL) jets.
