BOEING EB-47E STRATOJET
The U.S. Army Air Forces issued its first requirement for a jet bomber in 1943. However, it was not until after the war, when German research on high-speed aircraft became available that the design of the B-47 was finalized. The B-47 became the first all jet bomber produced anywhere in the world. Over two thousand Stratojets were built between 1947 and 1957. During the early 1960s a number of B-47E models were converted for use as electronic intelligence gathering aircraft. Additional antennas were mounted on the aircraft and a "capsule" was installed in the aircraft's bomb bay that carried additional equipment to monitor radar and radio signals as well as two additional crew members.
