B-47 — The Stratojet Survivors
During World War II, the US Army Air Force maintained a policy of
using proven technology whenever possible. Rather than using the
more efficient water cooled engines and experiment with jets, the
USAAF stuck mainly to air cooled round engines. The idea was not
to take unneeded risks when you could build something simple and
reliable in large numbers. At the end of the war, all this would
change.
The US Air Force was born in 1947, and with it, the idea that an all-jet bomber was needed. Previously, bombers flew at such a high altitude that propeller fighter aircraft were not able to pose much of a threat. But with the advent of the jet fighter, these slower bombers would be sitting ducks. To address this requirement, the USAAF issued four different contracts to develop an all-jet bomber. These were the North American B-45 Tornado, Convair B-46, Boeing B-47 Stratojet, and the Martin B-48. Early on in the all-jet build-off, it was apparent that the B-45 and B-46 would be ready well before the other two aircraft. The USAF went ahead with testing of the XB-45 and XB-46 prototypes. The XB-46 turned out to be too narrow and lightweight to carry the equipment that was needed for a long range nuclear bomber, so it was canceled. The XB-45, however, performed well. It did have a short range, and its straight wings lead to a slower speed and higher fuel consumption than desired, but since the USAF needed an all-jet bomber as soon as possible, the USAF went ahead with the B-45 program as a medium range bomber. The idea was that the better of the B-47 versus B-48 competition would simply replace the B-45 when the time came.

The USAF concluded that the B-47 had far more potential than the B-48, and it flew more than 50 miles per hour faster than the Martin bird. As a result, the B-48 was canceled, and the B-47 entered production in 1952. Eventually, 2042 Stratojets were produced, making it the largest post-war bomber project. The B-47 Stratojet flew as the front line nuclear bomber until the B-52 was available in the late 50’s and early 60’s. The B-47 simply did not have the range that was needed for the job, and remote basing overseas was becoming increasingly difficult and expensive. The B-47 was also used in a recon role as the RB-47, and as a weather tracking plane as the WB-47. The RB-47 flew some of the most dangerous missions of the cold war testing Soviet radar installations, and several were shot down. The B-47 was retired long before it was worn out in the early 1960’s, with some of these specialized birds hanging on through the 1960’s. I am not going to be able to add much to the B-47 story. The B-47 was mostly retired before I was born, and I never had the opportunity to see one fly. If you want to dive more deeply into B-47 history, start at the B-47 Stratojet Association website. I can, however, appreciate the importance of the B-47. The B-47, with its ability to deliver the nuclear bomb anywhere on the face of the earth, kept the Soviets in check in the mid to late 1950’s. The fact that the Stratojet never had to drop a nuclear bomb on the Soviets attests to its success at keeping the peace. Despite its critical role in the early cold war, the B-47 seemed to fade into the sunset as fast as it had arrived. Of the more than 2000 aircraft built, only about two dozen survive, none of which are in flyable condition. If you do want to see the B-47 in action, watch the classic movie Strategic Air Command, starring Jimmy Stewart as Col. Robert “Dutch” Holland, who pilots the Stratojet back when the job was big and the pay was small. The B-47 nose section used in filming the movie is on display at the March Field Museum.
