This was a daylight precision bombing mission involving 29 planes from the 6th Bomb Group:
On 22 June, the Group again went after the Kawasaki plant at Akashi with thirty aircraft, carrying three 4000 pounders each.
Formations were successfully obtained and bombing was visual, but the results were mediocre as only 10 per cent of the roof area
of the plant was damaged. Enemy fighters attacked, but did little damage, and three attempts at air-to-air bombing with phosphorous
bombs were also ineffective. Three ships received minor damage.
