JASSM family missiles are guided by a combination of GPS/INS positioning en route, and Imaging Infrared (IIR) for final targeting. They carry a dual-mode penetrator and blast fragmentation warhead at subsonic speed, in a body shape designed to have a very low radar profile. Originally an all-moving vertical stabilizer was to be used, but was abandoned because of doubts about hydraulic actuator reliability. This modification also replaced the B model's TERCOM and integrated a GPS capability with the existing inertial navigation system computer . Joined by Ed Wells, Boeing vice president of engineering, the engineers worked that night in The Hotel Van Cleve in Dayton, Ohio, redesigning Boeing's proposal as a four-engine turbojet bomber. Seven B-52Gs from Barksdale AFB launched 35 missiles at designated launch points in the U.S. Central Command's area of responsibility to attack high-priority targets in Iraq. Several projects beyond the B-52, the Convair B-58 Hustler and North American XB-70 Valkyrie, had either been aborted or proved disappointing in light of changing requirements, which left the older B-52 as the main bomber as opposed to the planned successive aircraft models. The bombings demoralized the defending Iraqi troops, many of whom surrendered in the wake of the strikes. [152] The aircraft was planned to fly towards the target at 400–440 mph (640–710 km/h) and deliver their weapons from 400 ft (120 m) or lower. [102] LITENING pods have been fitted to a wide variety of other US aircraft, such as the McDonnell Douglas F/A-18 Hornet, the General Dynamics F-16 Fighting Falcon and the McDonnell Douglas AV-8B Harrier II. Built to carry nuclear weapons for Cold War-era deterrence missions, the B-52 Stratofortress replaced the Convair B-36 Peacemaker. [93] On 15 December 2006, a B-52 took off from Edwards with the synthetic fuel powering all eight engines, the first time an air force aircraft was entirely powered by the blend. [138], Data from Knaack,[276] USAF fact sheet,[197] Quest for Performance[277], A B-52 carrying nuclear weapons was a key part of Stanley Kubrick's 1964 black comedy film Dr. Strangelove or: How I Learned to Stop Worrying and Love the Bomb. ", Boeing B-52 evolves again with guided weapons launcher, "New Life for Buff: Older than its pilots, the B-52 gets ready to fly for 100 years. ", "May 1960 – The U-2 Incident. [50] The thorough development,[Note 2] including 670 days in the wind tunnel and 130 days of aerodynamic and aeroelastic testing, paid off with smooth flight testing. [226] The B-52 has the capacity to "loiter" for extended periods, and can deliver precision standoff and direct fire munitions from a distance, in addition to direct bombing. Capacity for one - just 50 near-simultaneous C-17 sorties, each deploying 3-4 such pods could put 1800 cruise missiles on target, clearly overwhelming any current defense capabilities. However, by the late 1960s the Air Force concluded "that the Quail was only slightly better than nothing.". [53] At the roll-out ceremony on 18 March 1954, Air Force Chief of Staff General Nathan Twining said: The long rifle was the great weapon of its day. In the light of increased Chinese and North Korean military posturing, Stratoforts have returned to their old Vietnam base of operations, Andersen AFB on Guam, as part of a continuous deployed bomber presence forward in the Pacific. The B-1B holds almost 50 world records for speed, payload, range, and time of climb in its class. [132], The B-52B was the first version to enter service with the USAF on 29 June 1955 with the 93rd Bombardment Wing at Castle AFB, California. [69] In March 1965, the United States commenced Operation Rolling Thunder. Completion of the destruction task was verified by Russia via satellite and first-person inspection at the AMARC facility. [119], AGM-183A Air-Launched Rapid Response (ARRW) hypersonic missile and the future Long Range Stand Off (LRSO) nuclear-armed air-launched cruise missile will join the B-52 inventory in the future. Mines laid down by B-52s could establish mine fields in significant enemy choke points (mainly Kurile islands and GIUK). When the fighter drew within range, Turner fired his quad (four guns on one mounting) .50 caliber machine guns. Either change would make it too large to fit on the SRAM launchers, and more annoyingly, the extended-fuselage version would be too large to fit in the bomb bay of the new B-1 Lancer bomber. These missiles, designated Block I, incorporate improvements such as a larger and improved conventional payload (1,360 kg, 3,000 lb blast class), a multi-channel GPS receiver and integration of the buffer box into the GPS receiver. [204] In late 2001, ten B-52s dropped a third of the bomb tonnage in Afghanistan. Eight of the nine crew were killed. [110] When the B-52G was retired in 1994, an urgent scheme was launched to restore an interim Harpoon and Have Nap capability,[Note 3] the four aircraft being modified to carry Harpoon and four to carry Have Nap under the Rapid Eight program. The small jet-powered drone aircraft had a simple inertial navigation system (INS) that allowed it to fly a pre-programmed course that would make it visible to known Soviet defensive sites. Why? "Air Force Depot Maintenance: Information on the Cost-Effectiveness of B-1 and B-52 Support Options (Briefing Report, 09/12/97, GAO/NSIAD-97-210BR). [178] Diamond Lil is preserved on display at the United States Air Force Academy in Colorado. 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 defenses with hundreds of tiny, low-flying targets that were extremely difficult to see on radar. As for conventional cruise missiles, one likely to have been scrutinized in the study was the stealthy Northrop AGM-137 Tri-Service Standoff Attack Missile, or TSSAM. [14] However, by October 1946, the Air Force began to express concern about the sheer size of the new aircraft and its inability to meet the specified design requirements. In 1996 Rolls-Royce and Boeing jointly proposed to fit B-52s with four leased Rolls-Royce RB211-535 engines, but this plan failed because of Air Force resistance to leasing combat assets and a negative Air Force economic analysis which was later disputed as flawed. [96] [209][210], From the 1980s B-52Hs were modified to use Harpoons in addition to a wide range of cruise missiles, laser- and satellite-guided bombs and unguided munitions. This missile was developed to increase the effectiveness and survivability of the Boeing B-52H Stratofortress strategic bomber. A request for proposals was planned for mid-2019, with service entry by 2024. [78] The 1760 IWBU allows precision-guided missiles or bombs to be deployed from inside the weapons bay; the previous aircraft carried these munitions externally on the wing hardpoints. Thus, a comfortable temperature setting for the pilots caused the other crew members to freeze, while a comfortable temperature for the bottom crew caused the pilots to overheat. The B-52s took over heavy bombing after B-1 Lancers that had been conducting airstrikes rotated out of the region in January 2016. [9] Like the AGM-86, the LRSO can be armed with either a conventional or nuclear warhead. Criticizing the Air Force cost analysis, the DSB found that among other things, the Air Force failed to account for the cost of aerial refueling; the DSB estimated that refueling in the air cost $17.50 per gallon, whereas the Air Force had failed to account for the cost of fuel delivery and so had only priced fuel at $1.20 per gallon. The DSB urged the Air Force to re-engine the aircraft without delay,[125] saying doing so would not only create significant cost savings, but reduce greenhouse gas emissions and increase aircraft range and endurance; these conclusions were in line with the conclusions of a separate Congress-funded study conducted in 2003. Townsend. Thus modified, B-52Ds could carry 22,000 lb (9,980 kg) more than B-52Fs. It took off from Edwards Air Force Base with a 50/50 blend of Fischer–Tropsch process (FT) synthetic fuel and conventional JP-8 jet fuel, which burned in two of the eight engines. An enemy force would have to counterattack each of the missiles, making defense against them costly and complicated. ", "Fact Sheet: 325 Weapons Squadron (ACC). Tags: Bombers Military Technology World B-2 B-21 B-1 B-52 B-52, B-2 and B-21 Bombers Are Getting Nuclear-Tipped Cruise Missiles by … [165], Neil Sheehan, war correspondent, writing before the mass attacks on heavily populated cities including North Vietnam's capital. [3], Beginning with the successful contract bid in June 1946, the B-52 design evolved from a straight wing aircraft powered by six turboprop engines to the final prototype YB-52 with eight turbojet engines and swept wings. On Monday, Schairer presented Colonel Warden with a neatly bound 33-page proposal and a 14-inch scale model. -- The 2nd Bomb Wing hosted an Aircraft Monitor and Control test for the B-52H Stratofortress August 24-26, 2020. The Air Force is now arming its fleet of B-52 Bombers with prototype nuclear-armed cruise missiles to prepare the aircraft for the possibility of launching the Long Range Stand Off (LRSO) weapon. A total of 25 crewmen were killed in these losses. From 24 to 25 November 1956, four B-52Bs of the 93rd BW and four B-52Cs of the 42nd BW flew nonstop around the perimeter of North America in Operation Quick Kick, which covered 15,530 miles (13,500 nmi, 25,000 km) in 31 hours, 30 minutes. Quail, originally designed for the high-altitude mission, was modified with the addition of a barometric altimeter to allow it to fly at lower altitudes. Both conventional and nuclear versions of the weapon are required to reach initial operational capability (IOC) before the retirement of their respective ALCM versions, around 2030.
