During more than five decades of operational service, the Boeing B-52 heavy bomber has been the backbone of the strike capability of the U.S. Air Force. Its long range, ability to operate at high altitudes and capability to carry nuclear or precision-guided conventional ordnance to any point on the globe, has made it a key component of nuclear deterrence and U.S. National Security Strategy.

DEVELOPMENT AND DESIGN
Born of specifications for a new heavy bomber presented by Air Materiel Command in 1945, the first iteration of what would become the B-522, was the Boeing 464-40 created in 1946. This airframe was powered by turboprop engines, as jet engines were not yet seen as reliable or fuel efficient enough for long- range missions.
As development continued through the end of the decade, the project became the keystone for the fledgling U.S. Air Force’s Strategic Air Command under the direction of Gen. Curtis LeMay. At his insistence, the XB-52 and YB-52, which had more operational equipment, featured 35-degree swept wings with eight Westinghouse turbojet engines.
The YB-52 first took flight in April 1952 and subsequent ground and flight testing lead the Air Force to order 282 of the new heavy bombers, beginning with the delivery of three B-52As and 10 B-52Bs by 1954.
During the rollout ceremony, Air Force Chief of Staff Gen. Nathan Twining described the B-52 as “the long-rifle of the air age.”
The B-52 has since received many upgrades to communications, electronics, computing and avionics on the flight deck, as well as engines, fuel capacity and the weapons bay. These upgrades enable the B-52H to integrate into the new digital battlefield and precisely deliver a large array of weapons, from conventional, nuclear and smart bombs to conventional or nuclear cruise missiles, on targets anywhere in the world.
The use of aerial refueling gives the B-52 a range limited only by crew endurance.
Further development included a reconnaissance variant, as well as a model used as a launch platform for 93 NASA X-15 missions to explore the boundaries of space. A B-52H is currently used for launching other research vehicles by NASA’s Dryden Flight Research Center in California.
A total of 744 B-52s were built with the last, a B-52H, delivered in October 1962.
