Hello Schweik,
I believe you were more correct earlier. The Soviets were working close support for their ground forces for the most part and were stuck on the "Quantity has a quality all its own" mentality. I was reading through some of your links and the statement that the Airacobra Mk.I a speed of 306 MPH at Sea Level and 363 MPH @ 13,800 feet "making it as good as the Yak-3 and MiG-3 then in Russian production" also says a lot about those other two aircraft that are supposed to be about 35-40 MPH faster but apparently are not in actual service.
Note that these numbers for Airacobra Mk.I are pretty much in agreement with other well documented tests and at Sea Level is barely faster than the A6M2 on overboost.
If this was how well their best aircraft actually performed in the field, then later versions of the Airacobra must have been superstars in comparison.
If you think the P-39D was on par with the Yak-3 or that the Yak-3 only made 363 mph you are a bit off the mark. Either you made a typo or whoever you are quoting did I would assume they meant the Yak-1. P-39D was probably on par with the early Yak-1 which some units switched from to the P-39 as you can read in those articles I linked. It was certainly better than the MiG-3 which was considered below even the I-16 or LaGG-3. Most of the P-39s they used from 1943 were the later model variants, which had quite good performance (on paper at least).
A service that is installing 37 mm and 45 mm cannon in single engine fighters is hardly one that is satisfied with "lightly armed" fighters.
Ah, you are trying to get me coming and going eh? The 37mm is a big gun, but i think the reason they put it in was mostly for strafing tanks and as a quick way to put down something a little sturdier than usual like a Fw 190 fighter bomber variant or a Hs 129. But it was still (typically) only armed with 1 or 2 other guns.
The point is, they put exactly as much armament as they needed, no more no less. For shooting down fighters a hub mounted 20mm and one or two nose mounted HMG was plenty. Probably about the equivalent in effectiveness to the oft used four wing guns in so many US fighters, or the much maligned armament of the much maligned (but highly effective) Macchi 202, or the armament of (nearly identical but) highly praised Bf 109F series.
As for copying the P-47, I don't believe they had the technology to manufacture the turbocharger and the aircraft really didn't suite their style of fighting. Soviet fighters tend to be small and agile with relatively good power to weight ratios and at least fair acceleration. The Thunderbolt was none of those.
Well mate that is exactly my point. All the extra capability of the P-47 in terms of range, high altitude performance, payload etc. was basically useless from the Soviet point of view. How well can it cover our ground troops? How well can it escort the Sturmoviks? How well can it handle Bf 109G2 at 3,000 feet?
A) First of all, the Soviets DID spend a lot of time and effort in an attempt to get a more powerful inline into service. They just didn't have much success at it until late in the war.
B) Why spend the effort pulling an engine off a Lend-Lease aircraft when the whole aircraft is being supplied to you and the net result IF you are successful is that you get ONE aircraft instead of two. We have already discussed the short life spans of their engines in service, so it wasn't like there were going to be a lot of spares in good condition.
C) Remember the Soviet preference for Motor Cannon. None of the Lend-Lease engines could accept that setup except Airacobra but that required a remote mounted engine.... The copying of a B-29 was in a different time with different priorities and by that time, technology probably had improved a bit from its state during the war.
The fact that the Soviets kept trying to increase the power of the M-105 and kept trying the M-107 in tests throughout the war pretty much tells us that they were not satisfied with the performance of M-105.
Well, "a lot of time and effort" is a subjective concept. Are you really suggesting that they couldn't have reorganized priorities and got stronger engines in action more quickly if they had put enough emphasis on it? My argument is that the pace it moved was good enough as long as a Yak-1B can still shoot down Bf 109s.
The gun power isn't just a matter of rate of fire. The MG 151 has a MV of 960 M/S as compared to Breda 12.7 at 760 M/S.
The typical projectile also weighs about 75% more.... If it isn't twice as powerful, it is pretty close to that.
Right. Which adds up to their being roughly equal.
I never made that statement. My comment was although from performance numbers, it was pretty close to the 109F, its engine power was identical to the 109E, and no, I do not believe it was better than a 109F though the airframe had more potential for development.
I never said it was 'better', I said it was 'roughly equal'. Performance was clearly similar, armament was at most slightly inferior, agility was slightly superior and the 202 had slightly better wing loading. It probably came out even. Almost the same speed, climb rate, ceiling, range etc. etc.
As mentioned earlier, its reputation seems to me to be amazing considering how few aircraft there actually were in theater.
From January to December 1942, Italian fighters flew 23,555 sorties. About 30 percent were by Folgores.
There were only 30-70 Folgore as a monthly average in service in North Africa during this time.
This brings up the point I was getting at earlier: If THIS was the most plentiful modern fighter, then WHAT ELSE was flying all those sorties?
Maybe Pinnochio flying some Macchi M.14s?
Ok since you keep bringing it up, per Shores on November 1942, at the end of El Alamein, the actual (as in on-hand strength) TO&E for Italian fighters in the MTO Theater was:
Italians
Macchi 202
54° Stormo - 2
51° Stormo - 23
17° Gruppo CT - 33
153° Gruppo CT - 21
20° Gruppo CT - 11
4° Stormo CT - 28
3° Stormo CT - 20
RE 2001
22° Gruppo Aut CT - 21
Macchi 200
2° Stormo CT was listed as mixed MC 202 and 200 but doesn't list how many
54° stormo CT - 6
G.50bis
24° Gruppo Autonomo CT - 26
160° Gruppo Autonomo CT -7
So that is 138 x MC 202 on hand at that time, 21 x Re 2001, about 15 x MC 200, and 33 x G.50bis for a total of 207 fighters, 75% of which were top quality (MC 202 and Re 2001).
There were also 76 Cr 42s available but at that point they were only used as bombers and mostly flew at night. Very few were ever claimed by 1942 nor did they make any claims.
All this is from Meditteranean Air War Vol III pp 43-46. I think I have an earlier TO&E for them somewhere before the battle in which they had considerably more fighters but I'm having trouble finding it, Shores books lack sorely in useful chapter headings or a real index and being 600+ pages thick are a nuisance to search through trying to find anything.
That "disengage" is only temporary if the other fellow really wants you. The idea of maintaining energy is trading altitude for speed and converting that back to altitude, not bleeding it off puttering around near the ground. The fellow with the altitude can make high speed passes all day (or at least until he runs out of fuel) and keep the advantage.
I also don't believe the 109 could get away that easily with a simple swift climb. The P-40 probably also has a pretty decent zoom climb or at least close enough to get a shot if they start in similar states.
- Ivan.
The thing is if the P-40 dives and is chased by another pilot who really wants him, then at low altitude so long as it can extend sufficiently in the dive to turn around, you now have a new dogfight where the P-40 has a 200 hp advantage, turns better and may be a little faster. This is where a lot of Bf 109s and 202s got shot down. They were better off keeping the fight up above 20k if they could. Sometimes they couldn't such as when their own airbase was attacked.
