A lot depends on how many US fighters intercept the force over Hawaii - sure the Zeros are better than most of these, but both peashooters and P-35's can trash the the other Japanese aircraft. Hopefully the strikes get intercepted on the way in, hit by AAA over targets, and hit on the way out. Frankly losing the peashooters and P-35s is no loss, and hopefully a significant number of pilots will bail out to fight again (this worked much in the RAF's favor during the Battle of Britain). While a US airstrike against the Kido Butai may have a high loss ratio, the effect will depend on how many Zeros are available to intercept the strike - since the Japanese do not have radar you'll have some on CAP but the rest need to be launched when the incoming raid is spotted. I would expect any raid or raids on the Kido Butai to do some damage, and since the number of Japanese aircraft available for a counterstrike will certainly be limited, IMHO Yamamoto will head home rather than try and find the US carriers. Staying around will expose his force to more land based attacks, and potential for a surface engagement where he will be outnumbered.

The Japanese can run away faster than the battle fleet can catch them especially given they have a lead. While Halsey may order the one strike, with the losses the USN will take and the fact that PH has been hit and there is some damage there, chasing after a Japanese force larger than his without proper support arranged is too risky so my bet is that there is one carrier strike on the Japanese (max) and maybe one or two land based strikes, which given the effectiveness of high altitude bombing against ships will be unlikely to inflict significant damage.

Yamamoto gambled and lost, like a good poker player he knows when to fold his hand and once he has recovered his planes he will start moving away from Hawaii. All he knows is that the carriers were not at Pearl, he has no idea where they are and certainly is not about to go looking for them.

In real-life Midway, a group of 26 Buffalos and Wildcats was torn to pieces fighting 36 Zeros. At Pearl, the 1st wave had 40+. And the P-26 was so slow, it would have, at best 1 chance of a frontal attack (assuming it could even climb fast enough) and then the entire IJN strike force would leave them behind. The P-35 wasn't much better...
 
Wasn't the Brewster aircraft company found to be very poorly managed and run during the war?

In 1944 the Brewster company was making components for other aircraft companies. The delivery & quality was so bad the USN seized the facility & installed new management. Farrago in 'Game of the Foxes' makes a case the plant manager & senior engineer were nazi sympathizers.

To be honest, we should probably not attribute this to sabotage but stupidity
 
By the way, Utah is not just a target ship, she also is a gunnery training ship for the AA gunners of the fleet. As a result she has some of the more modern weapons for AA use aboard ship. She had four 5"/38s, four 5"/25s, two 1.1" quads, and as many as fifteen .50 cal MGs. With advance warning, she would have added her AA firepower to the general defence of the fleet.

The Fighter Group at Midway were flown mostly by reservists, & had less of the appropriate training than their Navy peers. While the carrier air groups were fairly good there was a large mass of USN & USMC squadrons ashore without a lot of aggregate flight hours.

many were barely out of fighter school while the Japanese pilots had six more months of combat experience they do not have here in this scenario
 
If the US Fleet is getting prepared at 0330 in a somewhat orderly fashion, might there be a message sent to the AP WW Burrows for them to alter course? IOTL they didn't receive orders until the day after the PH attacks to return to Hawaii and, prior to arriving there, to get routed to Johnston Island.

Great timeline and looking forward to future updates.

there is an alternate strip at Hilo (modern day Hilo International Airport) which has been upgraded for military use but is not yet occupied by a unit (other than some engineers). At O330 AM Hawaii time the B17s are past the point of no return so they will be diverted to Hilo once it becomes clear an air attack is underway

the ships near French Frigate will be diverted to move closer so that they have destroyer protection (as one is present) and ASW air cover from float planes patrolling from there, that includes the Burrows

As of 0330 -0600 the Fleet simply thinks that Japanese submarines must be in the area. The presence of the carrier fleet is suspected but not confirmed.

it was moved in proximity to two battleships not only as a torpedo block ship from submarine attack, but also for its air defense support (just in case)

The training of the Japanese (or USN carrier wing pilots for that matter) counted the most at this point.

A portion of the Japanese carrier pilots had some combat experience over China. That and the experience of the Japanese Army air force led the Japanese to better tactics, and to improve their training overall. In Dec 1941 most of the IJN pilots (two groups excepted) had a very high number of flight hours accumulated. They knew their machines about s well as could be expected of any air force. The mass of US pilots (excepting some carrier wings) lacked that depth of flight time. Couple that with dated air combat tactics & unfavorable loss ratios were inevitable.

This here. The IJN had the edge on training, experience and equipment.

Yep. One of the few exceptions were some of the USN carrier wings. A effort was made to keep them stocked with the best pilots. There were inevitably rookies aboard, but on the carriers of the Pacific Fleet were concentrated the best. ln that narrow but critical segment the IJN edge was thin.
 
Honestly, the best that could happen to the USN was if, somehow, the US CVs hit the IJN CVs when their strike groups were over Pearl. That way, while the CAP Zeros would still win any fights, they would be too few to alter the result.
