Grumman F6F Hellcat
The Grumman F6F Hellcat is an American Carrier-based aircraft, carrier-based fighter aircraft of World War II. Designed to replace the earlier Grumman F4F Wildcat, F4F Wildcat and to counter the Japanese Mitsubishi A6M Zero, it was the United States Navy's dominant fighter in the second half of the Pacific War. In gaining that role, it prevailed over its faster competitor, the Vought F4U Corsair, which initially had problems with visibility and carrier landings. Powered by a Pratt & Whitney R-2800 Double Wasp, the same powerplant used for both the Corsair and the United States Army Air Forces (USAAF) Republic P-47 Thunderbolt fighters, the F6F was an entirely new design, but it still resembled the Wildcat in many ways. Some military observers tagged the Hellcat as the "Wildcat's big brother".Sullivan 1979, p. 4. The F6F made its combat debut in September 1943. It subsequently established itself as a rugged, well-designed carrier fighter, which was able to outperform the A6M Zer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grumman A-6 Intruder
The Grumman A-6 Intruder is a twinjet all-weather subsonic attack aircraft developed and manufactured by American aircraft company Grumman Aerospace. It was formerly operated by the U.S. Navy and U.S. Marine Corps. The A-6 was designed in response to a 1957 requirement issued by the Bureau of Aeronautics for an all-weather attack aircraft for Navy long-range interdiction missions and with short takeoff and landing (STOL) capability for Marine close air support. It was to replace the piston-engined Douglas A-1 Skyraider. The requirement allowed either single or twin-engined aircraft, as well as either turbojet or turboprop-based engines. The winning proposal from Grumman was powered by a pair of Pratt & Whitney J52 turbojet engines. The A-6 was the first U.S. Navy aircraft to have an integrated airframe and weapons system. Operated by a crew of two in a side-by-side seating configuration, the workload was divided between the pilot and weapons officer (bombardier/navigator ...

Apollo Lunar Module
The Apollo Lunar Module (LM ), originally designated the Lunar Excursion Module (LEM), was the lunar lander spacecraft that was flown between lunar orbit and the Moon's surface during the United States' Apollo program. It was the first crewed spacecraft to operate exclusively in the airless vacuum of space, and remains the only crewed vehicle to land anywhere beyond Earth. Structurally and aerodynamically incapable of flight through Earth's atmosphere, the Multistage rocket , two-stage Lunar Module was ferried to lunar orbit attached to the Apollo command and service module (CSM), about twice its mass. Its crew of two flew the Lunar Module from lunar orbit to the Moon's surface. During takeoff, the spent descent stage was used as a launch pad for the ascent stage which then Lunar orbit rendezvous, flew back to the command module, after which it was also discarded. Overseen by Grumman, the LM's development was plagued with problems that delayed its first uncrewed flight by about ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
