How many b 52 bombers are there

It had a rocky beginning. The original XB design, selected by the Army Air Forces in , was for a straight-wing, six-engine, propeller-powered heavy bomber. On Oct. Over the following weekend, in a Dayton hotel room, the team designed a new eight-engine jet bomber, still called the B, made a scale model out of balsa wood and prepared a page report.

The first BA flew Aug. After assembly of three BAs, production converted to BBs, with more weight and larger engines. Some had photoreconnaissance or electronic capsules in their bomb bays and were redesignated RBBs. The turbofan powered BH, the final version of the B, made its first flight March 6, , and is still in service. Feature Stories.

B Customer. B Quick Facts. Boeing engineers designed special landing gear that could align with the runway allowing special takeoffs and landings.

The original design of the B placed a gunner in the tail of the aircraft. Later designs moved the gunner forward with the rest of the crew.

After the Gulf War in the early s, the gunner position and defensive machine guns were eliminated. Air Force engineering studies suggest that the lifespan of the B could extend beyond The higher availability rate coupled with the larger number of Bs in the current force means that on many days, most of the long-range strike aircraft available for combat are Bs.

This situation is not going to change. Air Force planners have been unhappy with some features of the B-1 bomber since it first joined the force, most notably its electronic architecture for defending the aircraft and conducting strike missions.

The B-2 is by far the stealthiest bomber in the force, but the combination of small numbers and complex maintenance procedures required to preserve its low-observable features is a challenge to readiness. The Air Force has made major strides in bolstering the mission-capable rate of B-1 and B-2, but neither plane is likely to ever surpass the readiness for combat of the B Compared with the cost of operating and sustaining other heavy bombers, the B is not particularly expensive.

However, there is no guarantee the planes will be reengined. Somehow, the Air Force never gets around to buying new engines. Fuel costs do not look to be a major driver of modernization decisions going forward. Either way, though, the B is certain to remain in the heavy bomber fleet even as other, newer bombers head for the boneyard.
