98th BOMBARDMENT WING DETACHMENT IV: KB-29s 1952 - 1953
Detachment IV, with K-B29s at Yokota Air Base, Japan is somewhat of a mystery as they flew both "intruder" missions and refueling missions. Some missions were classified "combat" since they did in fact fly into the combat zone over the Sea of Japan.
They used the single point refueling system with a trailing drogue. Fighter aircraft being refueled used a wing tank probe to couple with the drogue. The KB-29s had no gun turrets, however carried two scanners along with the refueling operator in the back. They flew un-pressurized during refueling operations due to the large concentration of fumes. This required the crew to be on Oxygen during that time.
At this time it is unknown when the KB-29s were withdrawn.
