B-52 Bomber


 


b-52_hero_lrg_01_1280x720.jpgThe B-52 Stratofortress is a long-range, subsonic, jet-powered strategic bomber designed and built by Boeing and operated by the U.S. Air Force (USAF).

Beginning with the successful contract bid on 5 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. The aircraft first flew on 15 April 1952 with “Tex” Johnston as pilot.  Built to carry nuclear weapons for Cold War-era deterrence missions, the B-52 Stratofortress replaced the Convair B-36. Although a veteran of a number of wars, the Stratofortress has dropped only conventional munitions in combat. The B-52 carries up to 70,000 pounds (32,000 kg) of weapons.  Its Stratofortress name is rarely used outside of official contexts; it has been referred to by Air Force personnel as the BUFF (Big Ugly Fat Fellow).

The B-52 has been in active service with the USAF since 1955. The bombers flew under the Strategic Air Command (SAC) until it was disestablished in 1992 and its aircraft absorbed into the Air Combat Command (ACC). This remained the case until February 2010 when all B-52 Stratofortress and B-2 Spirit aircraft were transferred from ACC to the recently established Air Force Global Strike Command (AFGSC). Superior performance at high subsonic speeds and relatively low operating costs have kept the B-52 in service despite the advent of later aircraft, including the Mach-3 North American XB-70 Val Kyrie, the supersonic Rockwell B-1B Lancer, and the stealthy Northrop Grumman B-2 Spirit. The B-52 marked its 50th anniversary of continuous service with its original primary operator in 2005. (Other aircraft with similarly long service include the English Electric Canberra, the Tupolev Tu-95, the Lockheed C-130 Hercules, the Boeing KC-135 Stratotanker, and the Lockheed U-2.)
