B-52

Also called  Stratofortress,   U.S. long-range heavy bomber, designed in 1948 and first flown in 1952. Though originally intended to be an atomic-bomb carrier capable of reaching the Soviet Union, it proved adaptable to a number of missions, and some B-52s were thus expected to remain in service for the rest of the 20th century. The B-52 has a wingspan of 185 feet (56 m) and a length of 160 feet 10.9 inches (49 m). It is powered by eight jet engines
