B-1B
The Rockwell B-1 Lancer is a supersonic variable-sweep wing, heavy bomber used by the United States Air Force. It has been nicknamed the "Bone" (from "B-One"). , it is one of the United States Air Force's three strategic bombers, along with the B-2 Spirit and the B-52 Stratofortress. It is a heavy bomber with up to a 75,000-pound (34,000 kg) of payload. The B-1 was first envisioned in the 1960s as a bomber that would combine the Mach 2 speed of the B-58 Hustler with the range and payload of the B-52, ultimately replacing both. After a long series of studies, North American Rockwell (subsequently renamed Rockwell International, B-1 division later acquired by Boeing) won the design contest for what emerged as the B-1A. Prototypes of this version could fly Mach number, Mach 2.2 at high altitude and long distances and at Mach 0.85 at very low altitudes. The program was canceled in 1977 due to its high cost, the introduction of the AGM-86 ALCM, AGM-86 cruise missile that flew t ...

Northrop B-2 Spirit
The Northrop B-2 Spirit, also known as the Stealth Bomber, is an American heavy strategic bomber, featuring low-observable stealth technology designed to penetrate dense anti-aircraft defenses. A subsonic flying wing with a crew of two, the plane was designed by Northrop (later Northrop Grumman) as the prime contractor, with Boeing, Hughes, and Vought as principal subcontractors, and was produced from 1988 to 2000. The bomber can drop conventional and thermonuclear weapons, such as up to eighty Mk 82 JDAM GPS-guided bombs, or sixteen B83 nuclear bombs. The B-2 is the only acknowledged in-service aircraft that can carry large air-to-surface standoff weapons in a stealth configuration. Development began under the Advanced Technology Bomber (ATB) project during the Carter administration, which cancelled the Mach 2-capable B-1A bomber in part because the ATB showed such promise. But development difficulties delayed progress and drove up costs. Ultimately, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bombing Of Iraq (1998)
The 1998 bombing of Iraq (code-named Operation Desert Fox) was a major bombing campaign against Iraqi Armed Forces, Iraqi targets, from 16 to 19 December 1998, by the United States and the United Kingdom. On 16 December 1998 Bill Clinton announced that he had ordered strikes against Iraq. The strikes were launched due to Iraq's failure to comply with United Nations Security Council resolutions and its interference with United Nations Special Commission, United Nations inspectors that were searching for potential weapons of mass destruction. The inspectors had been sent to Iraq beginning in 1991 and were repeatedly refused access to certain sites. The operation was a major flare-up in the Iraq disarmament crisis as it involved a direct attack on Iraq. The aim of the bombing was to disable military and security targets which may have enabled Iraq to produce, store, maintain, and deliver weapons of mass destruction. The bombing campaign had been anticipated earlier in the year and fa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

B-52 Stratofortress
The Boeing B-52 Stratofortress is an American long-range, subsonic aircraft, subsonic, jet-powered strategic bomber. The B-52 was designed and built by Boeing, which has continued to provide support and upgrades. It has been operated by the United States Air Force (USAF) since 1955 and was flown by NASA from 1959 to 2007. The bomber can carry up to of weapons and has a typical Range (aeronautics), combat range of around without aerial refueling. After Boeing won the initial contract in June 1946, the aircraft's design evolved from a straight wing, straight-wing aircraft powered by six turboprop engines to the final prototype YB-52 with eight turbojet engines and swept wings. The B-52 took its maiden flight in April 1952. Built to carry nuclear weapons for Cold War Nuclear strategy, deterrence missions, the B-52 Stratofortress replaced the Convair B-36 Peacemaker. The bombers flew under the Strategic Air Command (SAC) until it was disestablished in 1992 and its aircraft abso ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Variable-sweep Wing
A variable-sweep wing, colloquially known as a "swing wing", is an airplane wing, or set of wings, that may be modified during flight, swept back and then returned to its previous straight position. Because it allows the aircraft's shape to be changed, it is a feature of a variable-geometry aircraft. A straight wing is most efficient for low-speed flight, but for an aircraft designed for transonic or supersonic flight it is essential that the wing be swept. Most aircraft that travel at those speeds usually have wings (either swept wing or delta wing) with a fixed sweep angle. These are simple and efficient wing designs for high speed flight, but there are performance tradeoffs. One is that the stalling speed is increased, necessitating long runways (unless complex high-lift wing devices are built in). Another is that the aircraft's fuel consumption during subsonic cruise is higher than that of an unswept wing. These tradeoffs are particularly acute for naval carrier-bas ...

Strategic Air Command
Strategic Air Command (SAC) was a United States Department of Defense Specified Command and a United States Air Force (USAF) Major Command responsible for command and control of the strategic bomber and intercontinental ballistic missile components of the United States military's strategic nuclear weapon, strategic nuclear forces from 1946 to 1992. SAC was also responsible for strategic reconnaissance aircraft; airborne command posts; and most of the USAF's aerial refueling aircraft. SAC primarily consisted of the Second Air Force (2AF), Eighth Air Force (8AF) and the Fifteenth Air Force (15AF), while SAC headquarters (HQ SAC) included Directorates for Operations & Plans, Intelligence, Command & Control, Maintenance, Training, Communications, and Personnel. At a lower echelon, SAC headquarters divisions included Aircraft Engineering, Missile Concept, and Strategic Communications. In 1992, as part of an overall post-Cold War reorganization of the U.S. Air Force, SAC was disesta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Strategic Bomber
A strategic bomber is a medium- to long-range Penetrator (aircraft), penetration bomber aircraft designed to drop large amounts of air-to-ground weaponry onto a distant target for the purposes of debilitating the enemy's capacity to wage war. Unlike tactical bombing, tactical bombers, Penetrator (aircraft), penetrators, fighter-bombers, and attack aircraft, which are used in air interdiction operations to attack enemy combatants and military equipment, strategic bombers are designed to fly into enemy territory to destroy strategic targets (e.g., infrastructure, logistics, Military base, military installations, factories, etc.). In addition to strategic bombing, strategic bombers can be used for tactical bombing, tactical missions. There are currently only three countries that operate strategic bombers: the United States, Russia and China. The modern strategic bomber role appeared after Strategic bombing during World War II, strategic bombing was widely employed, and Atomic bombing ...

AGM-86 ALCM
The AGM-86 ALCM is an American Aerodynamics#Incompressible aerodynamics, subsonic air-launched cruise missile (ALCM) built by Boeing and operated by the United States Air Force. This missile was developed to increase the effectiveness and survivability of the Boeing B-52 Stratofortress#B-52H, Boeing B-52G and B-52H Stratofortress strategic bombers, allowing the aircraft to deliver its payload from a great distance. The missile dilutes an enemy's forces ability to respond and complicates air defense of its territory. The concept started as a long-range drone aircraft that would act as a decoy, distracting Soviet air defenses from the bombers. As new lightweight nuclear weapons emerged in the 1960s, the design was modified with the intent of attacking missile and radar sites at the end of its flight. Further development extended its range so much that it emerged as a weapon allowing the B-52s to launch their attacks while still well outside Soviet airspace, saturating their defense ...
