=========================================================================

The B-47 was the first all-jet production bomber in the Air Force and was the backbone of SAC's bomber fleet in the 1950s. The Air Force liked Boeing's design and ordered two prototypes. The first one, designated the XB-47, rolled out of its Seattle hangar Sept. 12, 1947. It made, its maiden flight Dec. 17, 1947.
The B-47 was classified as a medium bomber and was not intended for worldwide missions even though it could be refueled in flight. The B-47 proved very versatile and underwent many modifications. The earlier A models had a clear plexiglass bombardier nose and two .50-cal. machine guns in the tail. The E-models were upscaled to two 20mm cannons, the clear nose was eliminated and an optical dome was installed for the horizontal periscope bombsight.
The E models also received new engines capable of 7,200 lbs, of wet thrust (water, alcohol injection). Through its modifications the B-47's weight climbed, from 125,000 lbs. to 221,000 lbs.
This EB-47 was delivered to the Air Force Sept. 21, 1953. It was used as an electronic test platform and was taken over by the Navy in 1965 to be used in Electronic Counter Measure testing until it was retired from service in 1977.
It was originally assigned to the 376th Bomb Wing stationed out of Barksdale AFB, La. The 376th later moved from Barksdale AFB, to Lockbourne (now Rickenbacker) AFB in 1957. Since being designed in 1943, 2,042 B-47s were built.
