B-52D 'Stratofortress' Bomber (U.S.A.)

The Boeing B-52 Stratofortress is an American long-range, subsonic, jet-powered strategic bomber. The B-52 was designed and built by Boeing, which has continued to provide support and upgrades. It has been operated by the United States Air Force since the 1950s, and NASA for nearly 50 years. The bomber can carry up to 70,000 pounds of weapons and has a typical combat range of around 8,800 miles without aerial refueling.

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. The B-52 took its maiden flight in April 1952. The B-52 has been in service with the USAF since 1955, and NASA from 1959 to 2007. Built to carry nuclear weapons for Cold War–era deterrence missions, the B-52 Stratofortress replaced the Convair B-36 Peacemaker.
