I'd like to hope that the IJN radar operators can radio the Zeros so that they have at least a four min warning to get to 12,000 feet. Of course many of the Zeros were already at HA on CAP but broke ranks and dove down onto the TDBs. Radar on the carriers detecting the SBDs at at least a dozen miles combined with radios in the fighters and operational discipline in the cockpits will ensure that most of the Zeros assigned to HA CAP will remain there.The A6M2 hate a rate of climb of roughly 3,150 fpm and the SBDs were coming in over 12,000 feet from two different directions.
Just ask the crew of the Shoho.Getting hit by an American torpedo in 1942 is perfectly safe.
Better chance winning lottery.
Even if the Japanese radar were able to give altitude, you still had the torpedo bombers attacking as the SBDs approached, so what do you propose they do with the 50 (or so) CAP elements?I'd like to hope that the IJN radar operators can radio the Zeros so that they have at least a four min warning to get to 12,000 feet.

Add to that, scattered to broken cumulus clouds at SBD approach altitudes hindered CAP's scanning visibility, and a large percentage of the SBDs came from a direction the CAP pilots had not been briefed to expect.Of course many of the Zeros were already at HA on CAP but broke ranks and dove down onto the TDBs.
What radar gives the IJN is informed asset allocation. True their fighters can't be everywhere and need fuel and (in some cases) ammunition. So, have the existing LA Zeros combat the TBDs. The IJN knows that dive bombers are deadly, and that they're approaching enmasse. The IJN has proven thus far to be able to dodge torpedo strikes, but dive bombers are another story. I'm also not sure if the HA Zeros (those that we're not sending to LA) had fired a shot yet, so they should have some ammunition. Taking this into account, I'd leave all the HA Zeros in place, vectoring them onto the SBDs, it's the greater threat.Even if the Japanese radar were able to give altitude, you still had the torpedo bombers attacking as the SBDs approached, so what do you propose they do with the 50 (or so) CAP elements?
The Akagi, Soryu and Kaga were also gyrating, trying to evade the attacking TBDs and TBFs, creating a hot mess as far as the CAP's chasing the torpedo bombers.
Add to that, the SBDs were approaching from two different directions: from the west and from the south.
And finally, the CAP had been in the air for a considerable amount of time, expending both fuel and ammunition, how effective would they be if vectored in time?
With radar alerting of the coming strike the carriers can also make some rush preparations. Such as securing fuel lines, closing watertight doors, preparing damage control, and launching any aircraft on deck. I'm not suggesting the IJN survives the day, but radar, radios and teamwork (rather than army of one thinking) will make for an interesting day.
Even if the crews had enough time to drain and stow the fuel lines plus ventilating the hangar area AND secure the bombs and torpedoes that had been strewn about, there is still the issue of the SBDs' bombs setting off the aircraft that were crammed into the carrier's hangars.
The 1000-pound bomb hit amidships and penetrated the flight deck to explode on the upper hangar. The explosions ruptured the ship's avgas lines, damaged both her port and starboard fire mains and the emergency generator powering her fire pumps, as well as knocking out the carbon dioxide fire suppression system.[63]
The aircraft belowdecks of the three carriers were fueled and armed.

I find that a bit hard to swallow, given that IJN carriers generally had fully enclosed hangar decks without the large side openings our flattops had. Part of the reason there was so much excess ordnance about was that handling it was limited by lift capacity. There was no other way. No provision for rapid emergency jettison from the hangar deck.True that airplanes are themselves fire hazards, but with fuelies and ammo crews being separate, I don't see much issue with the two crews mitigating much of the hazard, albeit with a lot of elbow-grease.

As for defueling aircraft for hazard mitigation, "no way, Jose"! I've worked as an aircraft fueler/defueler, and for a muti-tank gravity fueled aircraft, it's a slow and arduous process, and when you're done, what have you got? An FAE bomb consisting of unusable and irretrievable fuel in an air and vapor-filled closed container. And there's no plumbing to jettison the removed fuel overboard, so it's likely still there waiting to be set off. Good luck with that.
Yo' Thumpster,Yeah, I wasn't imagining draining tanks in airplanes -- that's clearly too laborious to manage in battle. I was thinking much more about draining the fuel lines in the ship itself. As noted, the aircraft will themselves remain a fire hazard. I think that'd be better than fueled planes sitting in and amongst wet fuel lines and ammo rolling around, was my point. Kaga apparently had some forty tons of bombs and torpedoes slopping around the hangar-deck from the order-counterorder-disorder process between the strike return and the decisive attack. That could have possibly been cleared up with a little notice.
If the Japanese had 20-minutes notice by radar, and if they'd been of a defensive mindset, I think they could have drained fuel lines and stowed at least some ammunition. That's the what-if here, after all.
I think that's the only benefit radar on a Japanese ship could perhaps provide. Not saying it would; just saying that it could have done so.
Yo' Thumpster,
Military Aviation History Channel just put out a video "In Defense of the Worst Plane of WW 2, The Brewster Buffalo". Tell buffnut if ya' see him.
Can I ask, why did the IJN change ordinance?, the aircraft were loaded with land bombs to attack Midway, why didn't they just use them against the carriers, the carriers are unarmored, a 500Lb bomb hitting a wooden deck is going to cause a lot of damage, just launch and attack and have torps and AP bombs ready for the next strike.
Bear in mind, the Japanese tended to think of armored flight decks as the norm, as per their mentors, the British. Doctrine said land bombs for land targets, antiship bombs for ship targets, so that's what they did. Genda and Fuchida were both "under the weather" medically and not at the top of their game, and Nagumo was not an air minded admiral, despite being the most combat experienced carrier commander in the world at the time. So doctrine wasn't subject to ad hoc second guessing.Can I ask, why did the IJN change ordinance?, the aircraft were loaded with land bombs to attack Midway, why didn't they just use them against the carriers, the carriers are unarmored, a 500Lb bomb hitting a wooden deck is going to cause a lot of damage, just launch and attack and have torps and AP bombs ready for the next strike.
The ordnance lifts were designed to expeditiously deliver their cargo to the hangar deck. Sending ordnance "down the up staircase" was not part of the original plan, and required jury rigging and innovating, which was not going to happen quickly. Besides, a bomb hit with downloading in progress would provide an ignition path straight down to the magazines. Guy Faulkes would be amazed!Kaga apparently had some forty tons of bombs and torpedoes slopping around the hangar-deck from the order-counterorder-disorder process between the strike return and the decisive attack.

Punch through the compartments lining both sides of the hangar deck, and dump it all overboard.Yeah, but I'm not sure that'd be any worse than the alternative we saw play out. Guy Fawkes actually woke up, looked around, and said "holy crap!" on 4 June 1942. Trust me; he tweeted me a few weeks ago about this.
A lot of the magazine was actually not in the magazine. That's a problem. Best to address it ASAP, I reckon.
