It’s pure conjecture on my part but I would have to say that with the range of the P Boats they would have been likely to spot the Japanese fleet but it was Sunday so no aircraft other than an incoming squadron of B-17s were in the air.
However other aspects must be considered assuming the fleet was spotted. Would the warning be heeded. Could the US fleet have been dispersed on short notice? With the fleet dispersed would there be sufficient assets to defend Pearl Harbor?
