", "Bolstering Spirits in the Year of the B-2", "B-2 Bomber Set to Receive Massive Upgrade", "Stalth - First glimpses of the invisible aircraft now under construction", "Dextroamphetamine Use During B-2 Combat Mission. [25] Northrop (now Northrop Grumman) was the B-2's prime contractor; major subcontractors included Boeing, Hughes Aircraft (now Raytheon), GE, and Vought Aircraft.[7]. July 21st, 2012 The backbone of the United States Air Force is long-range strategic bombers. ", "Crisis in Libya: U.S. bombs Qaddafi's airfields. For other uses, see. Low observability provides a greater freedom of action at high altitudes, thus increasing both range and field of view for onboard sensors. [146][147] After the accident, the Air Force took the B-2 fleet off operational status until clearing the fleet for flight status 53 days later on 15 April 2008. Through Capstone, senior level officers are able to observe the significance of airlift and its role in all military operations. stealth while opening bomb doors has been achieved. Dawson, T.W.G., G.F. F-22 Raptor vs Sukhoi Su-57. The E-3 Sentry, which is an airborne warning and control system aircraft with an integrated command and…, Water survival tactics [62] The Common Very Low Frequency Receiver upgrade will allow the B-2s to use the same very low frequency transmissions as the Ohio-class submarines so as to continue in the nuclear mission until the Mobile User Objective System is fielded. Other sorties in Iraq have launched from Whiteman AFB. [113][114], Some analysts claim infra-red search and track systems (IRSTs) can be deployed against stealth aircraft, because any aircraft surface heats up due to air friction and with a two channel IRST is a CO2 (4.3 µm absorption maxima) detection possible, through difference comparing between the low and high channel.[115][116]. but the payload size and aircraft size has been reduced. Index. The newest Air Force Podcast recently dropped. Kitchen and G.B. Scott H. Spitzer), Pit stop⛽️ [130], The B-2's combat use preceded a U.S. Air Force declaration of "full operational capability" in December 2003. 5.0 out of 5 stars 1. Designed with aspects and features to resemble a B2 stealth bomber plane this military looking case is apt to turn some heads. These strikes were followed by an MQ-9 Reaper unmanned aerial vehicle firing Hellfire missiles. The cost to procure each B-2 was US$737 million in 1997 dollars, based only on a fleet cost of US$15.48 billion. 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. Globemaster III vs C-5 Galaxy. The U.S. Air Force Academy gives its cadets some unique opportunities. ", "Air Force Reorganizes Nuclear Commands. [56], In July 2010, political analyst Rebecca Grant speculated that when the B-2 becomes unable to reliably penetrate enemy defenses, the Lockheed Martin F-35 Lightning II may take on its strike/interdiction mission, carrying B61 nuclear bombs as a tactical bomber. When you consider that the B-52 was originally designed in 1946 and first flown in 1952, and is still in service with the US Air Force, I'd say that it is the best strategic bomber we have ever had. [109] Radars operating at a lower frequency band (S or L band) are able to detect and track certain stealth aircraft that have multiple control surfaces, like canards or vertical stabilizers, where the frequency wavelength can exceed a certain threshold and cause a resonant effect. [15][20] The Northrop design received the designation B-2 and the name "Spirit". [21] MIT engineers and scientists helped assess the mission effectiveness of the aircraft under a five-year classified contract during the 1980s. [13] Further studies were ordered in early 1978, by which point the Have Blue platform had flown and proven the concepts. [155] The exhibit features Spirit of Ohio's nose wheel door, with its Fire and Ice artwork, which was painted and signed by the technicians who performed the temperature testing. A peregrine falcon has been pictured in La Jolla, San Diego, California, as it dives downward and looks like a B-2 bomber. The U.S. Air Force reports its range as approximately 6,000 nautical miles (6,900 mi; 11,000 km). ", "B-2 Fire at AAFB Back in February of 2010 Was 'Horrific,' Not 'Minor'. The Northrop Grumman B-21 Raider is an American heavy bomber under development for the United States Air Force (USAF) by Northrop Grumman . 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. B-2 Bomber: Status of Cost, Development, and Production. [96] The B-2 lacks afterburners as the hot exhaust would increase the infrared signature; breaking the sound barrier would produce an obvious sonic boom as well as aerodynamic heating of the aircraft skin which would also increase the infrared signature. The B-2 is the only acknowledged aircraft that can carry large air-to-surface standoff weapons in a stealth configuration. [101] Four pairs of control surfaces are located along the wing's trailing edge; while most surfaces are used throughout the aircraft's flight envelope, the inner elevons are normally only in use at slow speeds, such as landing. [89], In order to make the B-2 more effective than previous bombers, many advanced and modern avionics systems were integrated into its design; these have been modified and improved following a switch to conventional warfare missions. A dramatic leap forward in technology, the bomber represents a major milestone in the U.S. bomber modernization program. "More Stealth Bombers Mean Less Combat Power". Northrop and Lockheed were awarded contracts in the first round of testing. Though designed originally as primarily a nuclear bomber, the B-2 was first used in combat dropping conventional, non-nuclear ordnance in the Kosovo War in 1999. Goodall, James C. "The Northrop B-2A Stealth Bomber.". [121][122] The hangars are built by American Spaceframe Fabricators Inc. and cost approximately US$5 million apiece. [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. [7] During this war, six B-2s flew non-stop to Yugoslavia from their home base in Missouri and back, totaling 30 hours. Aviation / Aerospace. share. Need some motivation to get your week started off right? Mahulikar. [32], In 1995, Northrop made a proposal to the USAF to build 20 additional aircraft with a flyaway cost of $566 million each. [7][66] At cruising altitude, the B-2 refuels every six hours, taking on up to 50 short tons (45,000 kg) of fuel at a time. Although this is only a rendering, and may not contain all the details the new aircraft will have, in this post I'll compare the… [42], The escalating cost of the B-2 program and evidence of flaws in the aircraft's ability to elude detection by radar[41] were among factors that drove opposition to continue the program. [41] Dellums and Kasich, in particular, worked together from 1989 through the early 1990s to limit production to 21 aircraft, and were ultimately successful. [119] In order to protect the operational integrity of its sophisticated radar absorbent material and coatings, each B-2 is kept inside a climate-controlled hangar (Extra Large Deployable Aircraft Hangar System) large enough to accommodate its 172-foot (52 m) wingspan. [121][122], The first operational aircraft, christened Spirit of Missouri, was delivered to Whiteman Air Force Base, Missouri, where the fleet is based, on 17 December 1993. [23] Unlike the Lockheed F-117 program, which was also a black project (the type of military project of which very few people knew even existed while it was being designed and developed) more people within the United States federal government knew about the B-2 and more information about the project was available. 9 comments. [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. Helicopter widths include main rotor diameter. [39][40], In its consideration of the fiscal year 1990 defense budget, the House Armed Services Committee trimmed $800 million from the B-2 research and development budget, while at the same time staving off a motion to end the project. [67] Each aircraft has a crew of two, a pilot in the left seat and mission commander in the right,[7] and has provisions for a third crew member if needed. [34][35] Maintenance costs are about $3.4 million a month for each aircraft. [86] In July 2009, Northrop Grumman reported the B-2 was compatible with the equipment necessary to deploy the 30,000 lb (14,000 kg) Massive Ordnance Penetrator (MOP), which is intended to attack reinforced bunkers; up to two MOPs could be equipped in the B-2's bomb bays with one per bay,[87] the B-2 is the only platform compatible with the MOP as of 2012. The B-2 was first publicly displayed on 22 November 1988 at United States Air Force Plant 42 in Palmdale, California, where it was assembled. [78], The B-2, in the envisaged Cold War scenario, was to perform deep-penetrating nuclear strike missions, making use of its stealthy capabilities to avoid detection and interception throughout missions. ", "Program office brings home 'wounded warrior'. Russia with Bear and Blackfire. It entered service in 1997 as the second aircraft designed to have advanced stealth technology after the Lockheed F-117 Nighthawk attack aircraft. NOTES: Shapes below depict aircraft from wingtip-to-wingtip / nose-to-tail assuming aircraft are being viewed from overhead perspective (the nose pointing towards the top of the screen). The B-2 brings massive firepower to bear, in a short time, anywhere on the globe through previously impenetrable defenses. Tensions between North and South Korea were high; after the exercise North Korea protested against the participation of the B-2s and made threats of retaliatory nuclear strikes against South Korea and the United States. China with the Tu16, Tu95. The most apparent difference is that the B-21 has a clean diamond-shaped center body section in contrast to the B-2’s more jagged rear center wing outline. Lancaster vs B-17 Flying Fortress. For battlefield communications, both Link-16 and a high frequency satellite link have been installed, compatibility with various new munitions has been undertaken, and the AN/APQ-181 radar's operational frequency was shifted in order to avoid interference with other operators' equipment. (U.S. Air Force photo/Gary Ell), OPERATION ALLIED FORCE -- A B-2 Spirit bomber prepares to receive fuel from a KC-135 Stratotanker during a mission in the European theater supporting NATO Operation Allied Force. At first glance, it looks just like its last bomber, the B-2 Spirit - not so fast. [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. During the late 1980s and 1990s, Congress slashed plans to purchase 132 bombers to 21. [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. [60] In 2012 projections, it was estimated that the Next-Generation Bomber would have an overall cost of $55 billion. [11] Northrop also had a classified technology demonstration aircraft, the Tacit Blue in development in 1979 at Area 51. ", "US had planned air strike to level Osama's Abbottabad hideout: Americas, News - India Today", US flies stealth bombers over South Korea, U.S. flies B-2 stealth bombers to S. Korea in "extended deterrence mission" aimed at North, "B-2 bombers kill nearly 100 ISIS terrorists in Libya", "Air Force: Sensor moisture caused 1st B-2 crash. ", "Semantic Designs Aligns with Northrop Grumman to Modernize B-2 Spirit Bomber Software Systems", "Northrop Grumman Adding Mobile Targets to B-2 Bomber Capabilities. [53] Changing the radar's frequency was required as the United States Department of Commerce had sold that radio spectrum to another operator. Comments. Lockheed had experience in this field due to developing the Lockheed A-12 and SR-71, which included a number of stealthy features, notably its canted vertical stabilizers, the use of composite materials in key locations, and the overall surface finish in radar-absorbing paint.
