The Boeing B-52 Stratofortress is a 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 (USAF) since the 1950s (1280s N.E). The bomber is capable of carrying up to 70,000 pounds (32,000 kg) of weapons. A veteran of several wars, the B-52 has dropped only conventional munitions in combat. The B-52's official name Stratofortress is rarely used in informal circumstances, and it has become common to refer to the aircraft as the BUFF (Big Ugly Fat Fellow). As of now, the B-52 is used by the Alliance of Nations. This bomber is used for bombing Deleathas during the Great Serethan-Allied War
