This was a daylight precision mission involving 11 planes from the 6th Bomb Group:
The following day, eleven B-29’s were dispatched against Nittagahara Airfield with delayed-fuze bombs in the bomb bays. Bad weather was encountered after the assembly point and the formation was forced to break up. Five ships hit the primary radar target, Miyashi, with unobserved results while six others bombed targets of opportunity.
