Boeing B-47 Stratojet
In mid 1944, the Air Force requested bids for a high performance, all jet design bomber. The third aircraft company to be awarded a development contract in the 1944 Air Force competition was Boeing with a straight wing design, which housed the four jet engines in the fuselage. This configuration was given the original XB-47 label. Results of preliminary testing did not encourage this type of arrangement, however. Tests continued on various designs with none offering the advanced performance sought.
In September, 1945, a swept back wing was introduced as a result of reports studied in German after World War II. This was what had been needed. The next problem was the engine location. More than fifty different positions and combinations were tried before the final placing was decided. This became Boeing Model 450, or the B-47.
The first Boeing XB-47 prototype proved the soundness of the radical design. Production contracts were awarded that eventually made the Statojet the backbone of the Strategic Air Command. Ten B-47A's made up the original order and it was followed by 398 B-47B aircraft. These two types were powered by six engines instead of the original design of four. These engines were the General Electric J47-GE-11 and -23 engines giving up to 5,800 pounds of thrust - 1,800 pounds more than the prototype's J35-GE-7 units.
Specifications: (Boeing B47E Stratojet)
The Boeing B-47 Stratojet was a medium-range and medium-size jet bomber capable of flying at high subsonic speeds and primarily designed for penetrating the airspace of the Soviet Union. A major innovation in post-World War II combat jet design, it helped lead to the development of modern jet airliners. While the B-47 never saw major combat use, it remained a mainstay of the U.S. Air Force's Strategic Air Command (SAC) during the 1950s and early 1960s.

An interesting item from Larry:
Bet you never seen one of those do a roll at about 5000 Feet?
Also how many of your readers know that the USAF in their wisdom
tried making the B47 in to QB 47 Drone, it happen at Eglin AFB Fla
in the 1960's. Later

Updates by Larry:
I do not remember where I got this from but it was taken at Eglin AFB Fla in the early 1960's I was in the 3205 Drone Sq and we flew out of Fld 3 Duke Fld QB 17 an QF 80 on the main base they was talk about doing QF 104 and QB 47 I left in 1959 so I know it had to be taken in late 1960 as the QF 104 they only did 22 QF 104 according the Qf104 bottomed out in early 1970 so the 22 of them lasted a long time as we lost a heck lot more QB 17 and QF 80 then that in the 2 years I was there. At any rate here is also two pictures of the one on display at Eglin before being refurbished and then after it was done. It currently is on display or was in 2001.
Hi, Bob Kunnel,
I was just surfing around trying to find anyone that was a B-47 enthusiast. The reason being is that I found a B-47 fuselage nose cover dated March 1960 and I have it up for auction on Ebay at http://www.ebay.com/itm/B-47-STRATOJET-ORIGINAL-Aircraft-Fuselage-Nose-Cover-/181126638893?pt=LH_DefaultDomain_0&hash=item2a2bfd2d2d if you know anyone that might be interested please tell them about it.
