This was a daylight precision raid on Toyokawa Naval Arsenal. The strike photos showed that the Sixth had achieved a high level of proficiency:
On 7 August the Group changed to a daylight precision attack on the Toyokawa Naval Arsenal, thirty-seven miles from Nagoya. Only twelve Sixth ships were scheduled and all bombed the primary target. No post-strike photography was made for damage assessment but strike photos indicated 90 per cent of the Sixth’s bombs fell within 1000 feet of the main point of impact.
