Aircraft totals do not equal ready defenders

The number of aircraft able to defend Oahu depends on whether reports count assigned, available, or operational machines and trained crews.

Question

How many defensive aircraft on Oahu could have met the Japanese attack?

Short answer

Probably enough if alerted, but the exact number depends on whether one counts assigned, available, or operational aircraft and ready crews.

Notes

A paper aircraft total does not show how many defenders could meet the raid. Assigned strength, physical availability, mechanical readiness, and crew availability are different measures. Oahu probably had enough aircraft for the task if warned, but no single exact figure works because the readiness definitions change the answer. Force structure and immediate combat power are different measures of strength.
