Boeing EB-47E (B-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.
