" Certain people felt very strongly that the FAA aircraft like the Swordfish were just as good as anything else flying..." This statement is a bit over the top,

Do you have a more nuanced version of this statement? Post it then.

especially after we've just had an in depth discussion of the strengths and weaknesses of the Swordfish. We've also discussed in some detail how the RN's carriers had no choice but to close to within range of the Luftwaffe's superior strike aircraft, and that the JU-87R could carry a heavier bomb load than the Val and could carry a 250kg bomb at least as far as any realistically feasible Val strike range.

Are you claiming that all the Ju-87 used against Pedestal or the previous convoys were Ju-87R with extended range? Because I'd love to see the numbers on that. For Pedestal I saw Ju 87D and Ju87B. How many Ju-87R were flying?

Which Allied carrier had the largest IJN strike directed against it in 1942? Which allied navy carrier force faced the strongest assembly of IJN carriers?

What was the largest IJN strike endured by USN carriers prior to Philippine Sea?

I'll answer this if you tell me what was the largest number of strike aircraft in any raid in Pedestal or one of the other Med convoys.

How many IJN strike sorties did USN carriers endure in 1942? How does the total of all IJN strikes directed against USN carriers in 1942 compare to total Axis strike sorties directed against Pedestal alone?

What was the heaviest bomb to strike a USN carrier in 1942?

Please support your last statement with some facts and sources.

That's a lot of work you are asking me to do lol. Count every sortie against all US carriers in 1942? Maybe somebody else will do that for you.

I still say the Skua, the Fulmar and the Sea Hurricane were pretty lousy fighters with a bad combat record.

EDIT: Added the Ki-48 Lily bomber and E8N scout plane, removed the B6N which wasn't available until 1943.

The Fulmar had a good record as a fighter, it's the top scoring FAA of all time. Yes, the Axis gave the Fulmar what it needed in the form of unescorted Stukas and Sparrowhawks, but that's not the Fulmar's fault. Put the Fulmar against any Axis monoplane single seat fighter and it's toast, but that wasn't really part of the Fulmar's combat experience.

But Skua, damn that's no fighter you FAA/AM fools.

Actually it's not hard at all. The IJNAF only attacked USN carrier TFs during ~ 6 battles in 1942.

Bougainville = 18 Bettys (plus a few more sorties against other carrier raids)

Coral Sea = 51 = 33 Val and 18 Kate

Midway = 28 = 18 Val and 10 Kate (two strikes)

Eastern Solomons = 27 Vals

Santa Cruz = 109 = 58 Vals and 51 Kates.
------------------------------------------------------

= ~224 IJN strike aircraft sorties against USN carrier TFs in all of 1942.

BWOC, the IJN flew about 180 attack sorties against units of the BEF on 5 and 9 April 1942.

The Axis AFs flew about 230 attack sorties against Pedestal alone during the time it was escorted by carriers.
 
You need to provide something more than that, simple repetition doesn't cut it.

Well, I already posted the results of their encounters with Japanese fighters in the Indian Ocean and that was pretty dismal

You missed the IJN Nakajima E8N 'Dave' : Nakajima E8N ~190mph and ~500nm range. It was used for recon during 1942.
and the E7K/E7K2 'Alf' Kawanishi E7K `~170mph and 1000nm range.

Neither the D4Y or B6N played any role as a carrier strike aircraft in 1942.

Only 25 D4Ys were built from early 1942 to early 1943, when it was put into volume production. AFAIK, it only flew a single sortie as recon aircraft at Midway.

The B6N did not enter production until Feb 1943.

All Variants of the JU87B onward could carry DTs but as we've discussed, this was rarely necessary because RN carriers had to operate within range of non DT equipped JU87s. JU87B/R max bomb load was 1000kg and Ju87D 2000kg,

I gave you an example of the JU87Rs sinking HMS Southampton at ~300 miles from Sicily.
 
Well, I already posted the results of their encounters with Japanese fighters in the Indian Ocean and that was pretty dismal

The Sea Hurricane had a very positive kill ratio during the Harpoon and Pedestal Convoys, 28 victories vs 8 losses, IIRC (Malta, the Spitfire Years). Only land based Fulmars encountered IJN aircraft during the attack on Ceylon and they and RAF Hurricanes did about as well as the USMC fighters on Midway.

Considering the Marine units were flying mostly Buffalo's... (20 out of 26 total)

Coral Sea = 51 = 33 Val and 18 Kate

Midway = 28 = 18 Val and 10 Kate (two strikes)

I think you are doing some really creative cherry-picking here, I'll unpack it when I have more time later today.

There was only one E8 "Dave" at Midway, flying from the Battleship Haruna, but you felt compelled to put that in. Right?

I never states I was making a Midway a cutoff, as Pedestal was several months later than Midway. I was comparing aircraft active in 1942. There were D4Y stationed in the Pacific through the second half of 1942.

The B6N did not enter production until Feb 1943.

You got me here, that was an oversight. I just saw first flight in 1941. It's what I get for being hasty.

All Variants of the JU87B onward could carry DTs but as we've discussed, this was rarely necessary because RN carriers had to operate within range of non DT equipped JU87s. JU87B/R max bomb load was 1000kg and Ju87D 2000kg,

The point about the Stukas and their normally very limited range, and same for the MC 202 and Bf 109s available) is that while you implied Pedestal was under attack by 600 aircraft, the reality is that 1) most of those 600 planes were not modern aircraft and many were not even really combat aircraft (rather recon or liaison), and 2) only a small percentage of the actually effective strike aircraft could attack the convoy at any one time.

The TO&E posted by Slaterat showed 26 x Ju 87D from I/StG 3, and 14 x Ju 87B & R . So that means at the very most, there were maybe a dozen Ju-87R flown by Italian pilots. Probably more like half a dozen. The elite StG 2 unit which sunk Southampton was in Russia by then.

The only relatively effective long range Strike aircraft available to the Axis during Pedestal were the 144 x Ju-88A they had stationed in Sicily. No doubt the reason they had so many of these in Theater is that they were the only really effective maritime strike aircraft the Axis had at the time. These were pretty good strike aircraft, though nowhere near as lethal of ship killers as say, the D3A. Or the Stuka. But the problem was their range far outstripped that of any of their fighter escorts. Even if you count the 8 x Bf 110C and 12 x Ju88C heavy fighters that were in Theater, these may best Skuas or Fulmars but would have a hard time against even Sea Hurricanes, let alone any of the land based fighters. This and the prevalence of the obsolescent Italian Trimotors in the force breakdown perhaps explains why so many of the air strikes against Pedestal resulted in "no damage".

Basically the only real danger zone was when they were coming within range of the German fighters (and Stukas) near Sicily and / or Tunis. The vast majority of this impressive force of 600 aircraft were no threat to Pedestal and the ones which could credibly attack did so piecemeal, and in much smaller number.

I gave you an example of the JU87Rs sinking HMS Southampton at ~300 miles from Sicily.

I don't know the actual distance to the target but the Southampton was sunk more than a year before Pedestal, during Operation Excess.
 
I know I have a habit of looking at things in a simplistic way but its served me well over the years. There can be no doubt that the Fulmar and the Sea Hurricane performed well when they had to. However it's also clear that this was almost certainly down to the skill of the pilots, the air intercept directors as well as the tactical situation they were in plus of course the majority of the opposition were unescorted.

It's also true that the Hurricane was inferior to the Me109E a fact that has been shown in many areas of conflict, and a Zero was at least as good as the 109E. There are comparison tests undertaken by Allied pilots which proved that the Zero was every bit as good as the Spit V so its ascendency over the Hurricane is unquestioned. Its worth remembering that the Allied Airforces in the Far East considered the Hurricane to be obsolete when matched against the Ki43 let alone anything else.

To believe that the Sea Hurricane and the Fulmar were even close to parity to the Zero or Ki43 is far from reality

Looking in from the outside there seems to be little difference between the dive bombers, the main difference would be in the quality of the training. Some types / versions had more range but in actuality all seemed to have had sufficient range for the jobs they were asked to do.

Agree with 90% of that. The dive bombers range was significantly different - I was being pretty generous with the Ju 87D I don't think it's actual strike range was anywhere near that far. But even if that was right, D3A is still ~300 miles longer range, which matters a lot in naval combat.
