Boeing YKB-29T Superfortress

Last revised April 17, 2000


It was found that the boom refuelling technique introduced on the KB-29P tankers was not as effective in refuelling small jet fighters as it was in refuelling large piston-engined bombers. The probe-and-drogue system was found to be more effective for refuelling these smaller aircraft.

A single KB-29M (45-21734) was converted to a three-hose tanker that could refuel three fighters simultaneously by the probe-and-drogue system. One hose was installed in the tail, and the two others were installed on reels mounted in pods suspended underneath the wingtips. This aircraft was redesignated YKB-29T. This was the first triple-point tanker for the Tactical Air Command. >[? By now, the B-29 was thoroughly obsolete and was too slow to be compatible with the newer jet fighters, and only one of these YKB-29T conversions was built. However, a similar triple-hose system was later used on KB-50 tanker conversions.
