'' basic history holds, the IJNAF was an elite force in 1941, but even the light losses in early 1942 saw, in Japanese eyes, a dilution of quality. It took mostly the fighting in the Solomons from the invasion of Guadalcanal to sometime in 1943 to reduce the IJNAF to a similar state as the Luftwaffe in 1944, a segment of very experienced and dangerous aircrew with the rest having troubles just flying. Going defensive and having good warning of allied raids helped disguise the decline for a time. Arthur Harris at his most cynical noted "fringe merchants" who dropped their bombs away from the target against the ones who tried and hit the target, the fringe merchants helped keep the good crew losses down. Though the usual rule in a dangerous situation is the less experienced your teammates are the more risk you are in. We know from late 1943 on allied pilots were willing to take more risks because of the decline in Japanese air power, then found themselves in trouble...''
The begining of the decline of the IJNAF carrier pilots force could be dating from the Santa Cruz Islands clash.
At Midway they had lost 4 flat tops but not yet so much as pilots and air specialists were concerned.
At Santa Cruz they technically won the battle but even if losing about as many planes as the USN, many US shot down pilots were rescued contrarily to the IJNAF that recovered very few of its downed crews and above all lost quite a numbers of well trained cadres and pilots.
