Boeing B-29 Superfortress

The B-29 "Superfortress" was a United States Army Air Force four-engine bomber, and the largest aircraft of World War II. The "Superfort", manufactured by Boeing, first took to the air in late 1942, and completed its first combat sortie in early 1944.

Perhaps the most recognized B-29 is the "Enola Gay", which dropped an atomic bomb on Hiroshima in 1945. The "Bocks Car", also a B-29, dropped another nuclear weapon on Nagasaki a few days later.

The Soviet Air Force's Tupolev Tu-4 was a bolt-for-bolt copy of the B-29, first widely revealed to the world audience in August of 1947.

The B-29 was soon made obsolete by the development of the jet engine and was replaced in the early 1950s by the Convair B-58 "Hustler", the Boeing B-47 "Stratojet", and eventually, the Boeing B-52 "Stratofortress".
