[91] Engine thrust became a key element of the B-2's aerodynamic design process early on; thrust not only affects drag and lift but pitching and rolling motions as well. However, Aviation Week editors found that there were no airspace restrictions above the presentation area and took aerial photographs of the aircraft's then-secret rear section[27] with suppressed engine exhausts. ", "B-2s return to flight after safety pause. The Anti-Radar Design Relies On A Complex Mix Of Materials. [80][81] The B-2 is capable of carrying 40,000 lb (18,000 kg) of ordnance. Pretty complex, huh? "The stealth technology developed from the program was later incorporated into other operational aircraft designs, including the B-2 stealth bomber".

[124] Depot maintenance for the B-2 is accomplished by U.S. Air Force contractor support and managed at Oklahoma City Air Logistics Center at Tinker Air Force Base. The mission, part of the annual South Korean–United States military exercises, was the first time that B-2s overflew the Korean peninsula. Afterwards, it became the B-2 Spirit. With aerial refueling support, the B-2 flew one of its longest missions to date from Whiteman Air Force Base, Missouri to Afghanistan and back. harvnb error: no target: CITEREFRichJanos1994 (, Graham, Bradley. "More Stealth Bombers Mean Less Combat Power". [81][118] In early 2004, Northrop Grumman began applying a newly developed AHFM to operational B-2s. ", USAF to Retire B-1, B-2 in Early 2030s as B-21 Comes On-Line. [125] The B-2 was the first aircraft to deploy GPS satellite-guided JDAM "smart bombs" in combat use in Kosovo. The U.S. Air Force reports its range as approximately 6,000 nautical miles (6,900 mi; 11,000 km). The B-2 is the only acknowledged aircraft that can carry large air-to-surface standoff weapons in a stealth configuration. [126] The use of JDAMs and precision-guided munitions effectively replaced the controversial tactic of carpet-bombing, which had been harshly criticized due to it causing indiscriminate civilian casualties in prior conflicts, such as the 1991 Gulf War. Low observability provides a greater freedom of action at high altitudes, thus increasing both range and field of view for onboard sensors. ", "The Air Force Announced It's Upgrading The One Plane It Needs To Bomb Iran. GENERAL ACCOUNTING OFFICE WASHINGTON DC NATIONAL SECURITY AND INTERNATIONAL A FFAIRS DIV, August 1995, p.16, 20, "Moisture in sensors led to stealth bomber crash, Air Force report says.". Share to Twitter Share to Facebook Share to Pinterest. [136] The B-2s flew directly from the U.S. mainland across the Atlantic Ocean to Libya; a B-2 was refueled by allied tanker aircraft four times during each round trip mission. [22], During its design and development, the Northrop B-2 program was a "black" project requiring a secret clearance for all program personnel before its revelation to the public. According to the Stefan–Boltzmann law, this results in less energy (thermal radiation in the infrared spectrum) being released and thus a reduced heat signature. The B-2 Spirit is a stealth bomber produced by Northrop Grumman. Both during development and in service, considerable effort has been devoted to maintaining the security of the B-2's design and technologies. "B-2 Shelter System [B2SS] Extra Large Deployable Aircraft Hangar Systems (Formerly: B-2 Shelter Program)", "Portable B-2 bomber shelters are built ... in parts (officially) unknown", "JDAM continues to be warfighter's weapon of choice. Unique video footage recently filmed in a U.S. Air Force B-2A Spirit stealth bomber cockpit just released. Although the bombers accounted 50 sorties out of a total of 34,000 NATO sorties, they dropped 11 percent of all bombs. Burying engines deep inside the fuselage also minimizes the thermal visibility or infrared signature of the exhaust. [6], The B-2 is capable of all-altitude attack missions up to 50,000 feet (15,000 m), with a range of more than 6,000 nautical miles (6,900 mi; 11,000 km) on internal fuel and over 10,000 nautical miles (12,000 mi; 19,000 km) with one midair refueling. The B-2 is a flying wingaircraft, meaning that it has no fuselage or tail. ", "Kasich still touts opposition to stealth bomber", "Zell Miller's Attack on Kerry: A Little Out Of Date. It is characterized by its many upgrades, political controversy, and continued service in the United States Air Force as a nuclear-capable first strike aircraft. During the 1980 presidential election campaign in 1979, Ronald Reagan repeatedly stated that Carter was weak on defense, and used the B-1 as a prime example. [60] In 2012 projections, it was estimated that the Next-Generation Bomber would have an overall cost of $55 billion. [67] "Forward operating locations" have been previously designated as Andersen Air Force Base in Guam and RAF Fairford in the United Kingdom, where new climate controlled hangars have been constructed. ", Capaccio, Tony. The B2 Cockpit features state-of-the-art avionics and flight control systems. It has significant advantages over previous bombers due to its blend of low-observable technologies with high aerodynamic efficiency and large payload. [103] The original design had tanks for a contrail-inhibiting chemical, but this was replaced in production aircraft by a contrail sensor that alerts the crew when they should change altitude. It is capable of all-altitude attack missions up to 50,000ft, with a range of more than 6,000nm unrefuelled and over 10,000nm with one refuelling, giving it the ability to fly to any point in the world within hours. Opposition in committee and in Congress was mostly broad and bipartisan, with Congressmen Ron Dellums (D-CA), John Kasich (R-OH), and John G. Rowland (R-CT) authorizing the motion to end the project—as well as others in the Senate, including Jim Exon (D-NE) and John McCain (R-AZ) also opposing the project. "Pressure mounts as stealth bombers deployed". The B-2 has a crew of two pilots, an aircraft commander in the left seat and mission commander in the right, compared to the B-1B's crew of four and the B-52's crew of five. [37] However a subsequent report in October 1996 noted that the Air Force had made some progress in resolving the issues with the radar via software fixes and hoped to have these fixes undergoing tests by the spring of 1997. GAO/NSIAD-95-164. One article includes cockpit footage from inside a B-2 Spirit stealth bomber, the first time outside video cameras have been allowed inside the jet. [110], RCS reduction as a result of shape had already been observed on the Royal Air Force's Avro Vulcan strategic bomber,[111] and the USAF's F-117 Nighthawk. [120], B-2s are supported by portable, environmentally-controlled hangars called B-2 Shelter Systems (B2SS). The B-2's clean, low-drag flying wing configuration not only provides exceptional range but is also beneficial to reducing its radar profile. Three B-2s dropped 40 bombs on a Libyan airfield in support of the UN no-fly zone. [16] The Northrop proposal was code named "Senior Ice" and the Lockheed proposal code named "Senior Peg". To avoid the possibility of suspicion, components were typically purchased through front companies, military officials would visit out of uniform, and staff members were routinely subjected to polygraph examinations. This stealth comes from a combination of reduced acoustic, infrared, visual and radar signatures (multi-spectral camouflage) to evade the various detection systems that could be used to detect and be used to direct attacks against an aircraft. "Defense worker loses job over his ties to India". The B-2s together dropped 108 500-pound precision-guided Joint Direct Attack Munition (JDAM) bombs. [59] In 2012, Air Force Chief of Staff General Norton Schwartz stated the B-2's 1980s-era stealth technologies would make it less survivable in future contested airspaces, so the USAF is to proceed with the Next-Generation Bomber despite overall budget cuts. [the integrator, Northrop Grumman (newspaper), Volume 8, No. These strikes were followed by an MQ-9 Reaper unmanned aerial vehicle firing Hellfire missiles.

[44], In time, a number of prominent members of Congress began to oppose the program's expansion, including later Democratic presidential nominee John Kerry, who cast votes against the B-2 in 1989, 1991 and 1992 while a U.S. It's where your interests connect you with your people. New images will be taken and uploaded as time and resources allow. ", "How Russia Could Someday Shootdown an F-22, F-35 or B-2 Stealth Bomber", "VI - STEALTH AIRCRAFT: EAGLES AMONG SPARROWS? This stealth comes from a combination of reduced acoustic, infrared, visual and radar signatures (multi-spectral camouflage) to evade the various detection systems that could be used to detect and be used to direct attacks against an aircraft. [27], In October 2005, Noshir Gowadia, a design engineer who worked on the B-2's propulsion system, was arrested for selling B-2 related classified information to foreign countries. "Integrated review of stealth technology and its role in airpower". [156], Data from USAF Fact Sheet,[7] Pace,[157] Spick[66], Sources: B-2 Spirit (Pace),[163] Fas.org[164], "B-2" and "Stealth Bomber" redirect here. [81][82], It was decided, in light of the dissolution of the Soviet Union, to equip the B-2 for conventional precision attacks as well as for the strategic role of nuclear-strike. The ATB project continued during the Reagan administration, but worries about delays in its introduction led to the reinstatement of the B-1 program. [85], In response to organizational issues and high-profile mistakes made within the Air Force,[132][133] all of the B-2s, along with the nuclear-capable B-52s and the Air Force's intercontinental ballistic missiles (ICBMs), were transferred to the newly formed Air Force Global Strike Command on 1 February 2010. The aircraft was severely damaged by fire while on the ground and underwent 18 months of repairs in order to enable it to fly back to the mainland for more comprehensive repairs. [32], In 1995, Northrop made a proposal to the USAF to build 20 additional aircraft with a flyaway cost of $566 million each. [126] The use of JDAMs and precision-guided munitions effectively replaced the controversial tactic of carpet-bombing, which had been harshly criticized due to it causing indiscriminate civilian casualties in prior conflicts, such as the 1991 Gulf War. In response, on 22 August 1980 the Carter administration publicly disclosed that the United States Department of Defense was working to develop stealth aircraft, including a bomber. [7] The B-2 is highly automated, and one crew member can sleep in a camp bed, use a toilet, or prepare a hot meal while the other monitors the aircraft, unlike most two-seat aircraft. [21] MIT engineers and scientists helped assess the mission effectiveness of the aircraft under a five-year classified contract during the 1980s. [67], To reduce optical visibility during daylight flights, the B-2 is painted in an anti-reflective paint. ", "Questions about whether the US needs another $55 billion worth of bombers. Troops from 82nd Airborne Division speak with Iraqi Federal Police members in Mosul, Iraq, June 29, 2017. [7] Nuclear ordnance includes the B61 and B83 nuclear bombs; the AGM-129 ACM cruise missile was also intended for use on the B-2 platform. [7] As of September 2013[update] the longest combat mission has been 44.3 hours. ", "President George H. Bush's State of the Union Address. [78], To address the inherent flight instability of a flying wing aircraft, the B-2 uses a complex quadruplex computer-controlled fly-by-wire flight control system that can automatically manipulate flight surfaces and settings without direct pilot inputs in order to maintain aircraft stability. ] B2SS hangars are known to have its own personality utilizing the code Senior Cejay 108 ] vertical...
