Interesting. I have read that the Su-2 could have been a good plane. IIRC it had the lowest loss rate per average missions. (IL-2, Su-2, Pe-2/3)The armor did not provide the IL-2 a reliable protection against neither large-caliber bullets nor anti-aircraft artillery shells. The only advantage of armor was better pilot survivability during emergency landings.
The distribution of armor thickness was not optimal, there were areas where there were no hits at all and vice versa, areas with a high percentage of hits had insufficient armor. Nearly every penetration of the cowl armor resulted in engine damage. Only the lower cowl armor provided sufficient protection.
In general, the IL-2 concept was very controversial - it was a bad idea to use a liquid-cooled engine on an attack aircraft. The result was a heavy, poorly maneuverable and rather vulnerable aircraft. I have to repeat: under the same conditions, obsolete fighters without armor used for ground attack suffered many times fewer losses. Yes, they were not as well armed as the Il, but nevertheless they could be very effective (for example, the I-207, which was not built in series, was highly appreciated). They also did not use the high-octane gasoline that the IL-2 required. There were other alternatives, starting with the very promising Vultee A-11.
The whole story of Soviet attack aircraft development is a clear illustration of the total inefficiency of the Soviet system.
Don't forget the Polikarpov - still active as a second line fighter in 1942, they acted as hornets protecting parachuting airmen. When the Old Man was in Severomorsk with the RAAF, there was an Yak on standing patrol - he was jumped by a Bf109. The Russian did a violent loop and came out of it with guns blazing and got the 109. Separately the Australians coached the Ruskis to maintain a standing patrol overhead. A raid started and up went the AA. The Yak on patrol immediately had its tail shot of by "Friendly AA; the pilot abandoned and the Yak did a vertical dive going through the roof of the Australian barracks - through 4 floors and ended up in the basement. A few parts of that Yak are in Australia.When I think of WW2 air combat i think of the US with the mustangs, the British with the Spitfires, the Germans with 109s and 190s, the Japanese with Zeros, and the Italians with the RE.2001. I almost never hear of soviet air to air. I have heard of the Il-2 and IL-10 which are both ground attack. I have heard other forum users refer to the "Yaks". I know they are made by Yakovlev but I don't think that the official designation was Yak. Was it? Was there also other companys making soviet fighters. I know ilyushin made the IL series but from what I know they are primarily ground attackers.
Thanks for taking the time to read this and hopefully answer this. Sorry if it was a stupid question.
and the germans with their mineshell design concentrated more on destroying the airframe itself and make the plane unflyable in that sense circumventing armour.The armor did not provide the IL-2 a reliable protection against neither large-caliber bullets nor anti-aircraft artillery shells. The only advantage of armor was better pilot survivability during emergency landings.
Yeah, cannons were the way to go, instead of solid projectiles that more often than not left an entry hole and an exit - if it didn't hit anything vital it just left holes - that said a 0.5" would be an awful shock to the system! I read somewhere an RAF report of 2 pilots who got to test the A36 Apache at the AAE Unit decided to do an end of day excursion to France and back shooting up a lot of stuff - they were really impressed!Most ground attack/CAS aircraft were easy to shoot down unless the forces using them had air superiority or air supremacy. The Stuka became a victim of this during the Battle of Britain. Even planes like the A-36 or Hawker Typhoon (and other fighters that were converted into CAS/attack aircraft) were often vulnerable during attack runs because of the need to slow down to make bombing/rocket/strafing runs with any accuracy. For the most part during World War II, in essence, speed was life. Yes, things like the Typhoon, P-47 and especially the A-36 could easily be maneuvered like fighters (which essentially they were, since the P-47 and Typhoon were outright converted fighters and the A-36 was an Allison powered P-51 converted for the attack fighter/dive bomber/CAS role) helped with survivability, but anytime you fly slow, you do make an easier target for AA or fighters attempting to intercept.
The Il-2 was far from alone in this (see also the Stuka and the Hs-129), though the Il-2 and the Hs-129's armor did provide some margin of protection for the pilots and some systems. IE, some guy with a MG-34 or MG-42 or a Maxim wasn't going to do much against a Il-2 or Hs-129. Hence one reason why so many 20mm and larger AA guns were commonly in use for the Germans and the Soviets, and even the Americans and the British/Commonwealth.
The problem is that the armor stopped completely aft of the cockpit. In early IL-2 seaters the gunner did not get armor (?). '
Granted a few dozen hits of 7.9mm in the rear fuselage and tail was usually not enough to bring down a plane unless control cables/push rods were cut.
Wings were unarmored and again, a few dozen holes seldom brought down a plane, it probably wasn't going to come back tomorrow. Took a while to inspect/patch.
Things change a bit with 20mm hits. Yes the IL-2 was strong but 20mm hits in rear fuselage/tail and wing had a much better chance of damaging/breaking structural components or damaging control surfaces. Some planes with good pilots made it home with large parts of the control surfaces missing. We don't hear about the pilots who didn't make it home with a large part of a control surface missing.
The IL-2 has been described as a flying tank but only the drive system and crew were armored. The suspension and track system (wings and flight controls) were not.
A tank with a broken track can still fight (poorly) but a plane with broken wing cannot fly.
Sorry, I read with delay.Hi DImlee.
I understand it might be tough getting good statistics on Soviet WWII missions by aircraft type. We have a somewhat free exchange of information and it's tough to get U.S. records of same and come up with stats that describe MOST of a type's service. It has to be harder to uncover Soviet records, accumulate them, and then do an analysis.
For now, I'll say that yes, the Soviets tried to use them as fighters when they could. That does not tell me how much they were able to do as they liked. As I said above, I suspect they didn't get to do as they wanted when the Germans were on the offensive, but DID when the German were retreating. Again, not too sure what percent of missions were fighter, escort, or ground attack.
Since you're Russian, I think you could likely answer that better than I can, or get a better estimate, anyway.
Just FYI, the guys I spoke with flew MiGs in the 1970s and 1980s. Mostly MiG-17s with some time in MiG-21s. They were under the impression that, despite desires to the contrary, the fighter missions were no more than about 50% of missions, with the balance being ground attack and escort. They were semi-sure most of the ground attack happened during the German retreat, many times in poor winter weather.
Doesn't mean they were right, but they had that opinion.
Cheers!
Yes, I belong to the same school of thought, so to speak. Just to add one more good feature of Su-2 - dual controls.The Su-2 was, in general, a quite successful versatile airplane. It was mainly used during the initial period of the war, when Soviet aviation was in crisis after the shock of the first days of the war. Nevertheless, the efficiency of the Su-2 was quite high. There were several reasons for this. The Su-2 was simple to operate and easily mastered by the crews. This increased the pilots' chances of gaining sufficient combat experience. The airplane was robust and was able to resist enemy hits. The Su-2 was conceived as a pure bomber and had no cannons - this, in fact, was its main disadvantage compared to the Il-2. But it could lift up to 600 kg of bomb load (up to 700 kg on tests) - the same amount was usually lifted by the twin-engined Pe-2! The Su-2 could not bomb from dive, however the Pe-2 was also used mainly as a level bomber until mid-1943 at least. In addition, a significant number of Su-2s were located on the southern sector of the front, where the activity of enemy fighters was lower, and the operating conditions corresponded exactly to the ideas according to which the airplane was designed. In 1942 Su-2 regiments had on average more experienced pilots than Il-2 and Pe-2 regiments, apparently this is the main reason for the lower losses, both combat and non-combat. In the same air division, Su-2 losses could be many times lower than Pe-2 losses (see the book by Dmitry Khazanov, unfortunately, only in Russian). This does not mean that the Su-2 had any outstanding qualities and could replace the Pe-2, but rather that the Pe-2 was insufficiently effective.
Although the regiment commanders and Su-2 crews were against the termination of serial production of the aircraft in 1942, the plant was decided to transfer to the production of the Il-2 M-82 despite the poor performance of the latter. Stalin did not like Pavel Sukhoi. The Soviet system in action...
Before the war, Sukhoi designed a very promising ShB (attack bomber) with four wing-mounted ShKAS and 600 kg of bomb load. If two ShKAS were replaced by 23-mm VYa, the installation of the M-82 allowed to get an airplane with the same armament as IL-2, but very probably with much better flight performance. The question of the necessity of armor for an aircraft with an air-cooled engine remains open. From my point of view, armor only deteriorated flight performance, providing no real protection for the crew. It is necessary to analyze statistical data - in particular, they are mentioned by Rastrenin in his books.
PS. The topic has been already discussed earlier (IL-2 doesn't suck as bad as the SU-2). I generally agree with Dimlee's opinion - seems that we read the same books about the Il-2 and Su-2.
Somewhere I've seen a P-51 that made it back home with basically half the rear fuselage blown away so monocoque structures are really damage tolerant.
I take any information from the former USSR about WW2 with skepticism. It was a closed society. When you look at the numbers of tanks supplied via Lend Lease, about 1 in 5 tanks on the battle field would have been Western, but its rare to see photos.Sorry, I read with delay.
About those guys from the Soviet Air Force of 1970s-1980s. Believe it or not, most of the Soviet officers in all branches were ignorant of the history of WWII, even of the German-Soviet(Great Patriotic) war. Their historical education was limited to the number of books approved by GlavPUR and studied in the military colleges, a number classified documents, but mostly - movies, and fiction literature. There was a short period in the 1960s and early 1970s when foreign military studies and memoirs became available in military libraries but it didn't last long.
Lend-leased equipment was usually described derogatively in the popular literature. "Slow and heavy" Hurricanes, "second-hand Tomahawks", "highly flammable" gasoline engines of foreign tanks, etc. As for the P-39, it was a mysterious aircraft for quite a long period. On one hand, the older generation (not just veterans) remembered the name "Aerokobra" because it was flown by Pokryshkin himself and it appeared in many wartime photos. On the other hand, P-39 was hardly mentioned in the post-war history books.
The Official Soviet History of the Second World War, published sometime in the 60's or 70's, devoted a single line of text to the entire Lend Lease effort. Apparently it was 'minor', and almost unworthy of mentioningI take any information from the former USSR about WW2 with skepticism. It was a closed society. When you look at the numbers of tanks supplied via Lend Lease, about 1 in 5 tanks on the battle field would have been Western, but its rare to see photos.
the old Soviet saying about Pravda and Tass, there's no news in the truth and no truth in the news.
Moreover, the effectiveness of the air war is apparently the subject of one of their more persistent propaganda efforts. It impacts aircraft performance data, admitted losses, and kill claims. Interesting treatment by Chris Lawrence in Aces at Kursk (from Dupuy Institute blog):I take any information from the former USSR about WW2 with skepticism. It was a closed society.

The press these days is all about sensationalism rather than facts. I find their reporting to be spectacularly bad and biased most of the time, except in aviation, where it is ALWAYS largely wrong. They get a few facts right and make up the restIn Collage I had a Statistics Professor that pointed to an Tass Article from the 1930's to show how at times the Soviet Propaganda did not outright lie, they just highlighted the facts in a way that showed the Soviet System in the best possible light.
The article was about the new Soviet designed and built car and how it stacked up to the competition. They held a race from the eastern part of the USSR, and ended in Moscow. At the time they were also making a License built Ford Model A Sedan and the race included a Ford and The new Soviet GAZ car. The Article stated that the Promoters were anticipating Dozens of entries in the race.
They Posted the Final Results that the GAZ placed in 2nd, and the Ford Finished 2nd from Last. Only if you did research and could come up with the Starting and Finishing lineups could you see that there where in fact only 2 cars entered in the race, they Finished Ford #1, GAZ #2. So in fact the GAZ entry did finish in 2nd place (behind the Ford) And the Ford did finish 2nd from Last in front of the only other entry the 2nd place finishing GAZ!
So he pointed out that the only real stretching of the truth was that the race promoters expected "Dozens" of entries. And that the other statements while technically Factual, made the reader think that the GAZ greatly outperformed the Ford. But they did not actually say that it did. I found his class very interesting, and always made me question everything a read in a for profit newspaper, where getting the story out 1st was more important than actually getting the facts correct.
