B-52H Stratofortress weapons payload
The B-52H, with a weapons payload of more than 70,000lb, is capable of carrying the most diverse range of weapons of any combat aircraft.
The nuclear weapons capacity includes 12 AGM-129 advanced cruise missiles (ACMS), 20 AGM-86A air-launched cruise missiles (ALCM) and eight bombs.
The conventional weapons payload is eight AGM-84 Harpoon missiles, four AGM-142 Raptor missiles, 51 500lb bombs, 30 1,000lb bombs, 20 AGM-86C conventional air-launched cruise missiles (CALCM), 12 joint stand-off weapons (JSOW), 12 joint direct-attack munitions (JDAM) and 16 wind-corrected munitions dispenser (WCMD).
WCMD was first deployed by the B-52 in 2002 in Afghanistan. JSOW entered service in 2003 and was deployed during Operation Iraqi Freedom.
The B-52 was the first aircraft to be equipped with the joint air-to-surface standoff missile (JASSM), which was cleared for operational use in October 2003.
In June 2006, Boeing was awarded a contract for the B-52 smart weapons integration next-generation (SWING), to support integration of future weapon systems such as JASSM extended-range, small diameter bomb and boost phase interceptor, until 2020.
In October 2006, Boeing announced that the B-52 can carry 32 small diameter bombs (SDB) on the common strategic rotary launcher in the bomb bay.
During Operation Iraqi Freedom in April 2003, a B-52 was fitted with the Northrop Grumman Litening II laser targeting pod, which was used to strike targets in Northern Iraq. In 2007, the USAF began fitting Litening to the B-52 fleet. The B-52 is fitted with the Lockheed Martin Sniper ATP advanced targeting pod. By December 2009, the Sniper demonstrated its capability to operate on B-52H aircraft.
In October 2010, Lockheed Martin-built JASSM successfully accomplished Lot 7 Reliability Assessment Programme flight tests at White Sands Missile Range, NM, by using B-52 and F-16 aircraft against a wide range of targets in various operational scenarios.
Boeing was awarded a eight-year, $11.9bn contract by the US Air Force in September 2010 to overhaul B-52H weapons systems.
The B-52H can also deliver 51 500lb, 30 1,000lb and 20 2,000lb navy mines.
