The 116 foot wingspan B-47 Bomber, called Stratojet and produced by Boeing, had a maximum weight and an ordnance capacity greater than most WW II heavy bombers. It was the first swept wing bomber to be deployed by the U.S.A.F.
The B-47 Bomber had jet fighter speed and maneuverability. It needed six jet engines for sufficient power, and even that had to be supplemented with Rocket Assisted Take-Off (RATO) from 18 booster rockets for heavy payloads.
The first B-47 Bomber aircraft did not have in-air refueling capability. This meant that they had to be deployed from basis within round trip range of the Soviet Union in order to act as a nuclear deterrent. Once in-flight refueling was adapted, missions as long as 36 hours long were flown to demonstrate the effectiveness of the aircraft.
Although the B-47 Bomber was intended for high altitude missions, the development of surface to air missiles by the Soviet Union altered that mission. It required the strengthening of its air frame in order to perform missions below Soviet radar detection levels. Another version of the aircraft was a dedicated reconnaissance plane.
When maximum deployment of the B-47 Bomber was achieved, over 1,300 of the aircraft served with 28 Strategic Air Command wings.
A total of 2,039 Boeing B-47 Bomber aircraft of all types were produced.
B-47 Bomber – model D
The B-47 Bomber model D was the world’s fastest combined jet and propeller powered aircraft with a top speed of 598 mph.
On Aug. 26, 1955 the first of two modified aircraft took to the skies to test the theory that an aircraft could have the acceleration of a propeller driven plane with the top speed of a jet. The aircraft had their inboard jet engines replaced with 9,710 hp turboprops driving huge 15 ft. diameter, 2 ft. wide propellers.
Tests found excellent performance and few problems. However, more modern jet engines were able to have quicker acceleration, and a combined jet and turboprop powered B-47 Bomber for the USAF was never developed for deployment.
The B-47 Bomber looks good and appears to have the proportions to make a good flying airplane. One with propellers and jets would make an interesting project. Imagine how it would sound with turbojets and engines turning propellers?

The AMA has plans for a control line model B-47 Bomber. It has a 46″ wingspan.
Model Aviation News also has plans for the B-47 Bomber. It has a 54″ wingspan and a length of 43″.
Capt. Midnight at WattFlyer started a construction thread about his B-47 Bomber with a 87″ wingspan and a 80″ length. Power comes from HETRC 6904 EDF units.
GGRW at WattFlyer is building a B-47 Stratojet with a 90 1/2″ wingspan that is 79″ long. It will be driven by Feigao motors and GWS fans.
