Hi Tony,
>I'm surprised at that. In RL, the Il-2's main weapons against tanks were rockets and bombs - the VYa-23 most were armed with could only penetrate 25-30mm so was really only effective against lightly-armoured tanks. OTOH, the Hurri's 40mm guns could penetrate 50+mm and achieved a good scoresheet - until the Tiger came along.
It seems that tanks were very hard to kill with boms in real life.
From Rudel's "Stuka":
"The sight of these masses of tanks reminds me of my cannon-carrying aircraft of the experimental unit, which I have brought with me from the Crimea. With this enormous target of enemy tanks it should be possible to try it out. It is true the flak defences covering the Soviet tank units are very heavy, but I say to myself that both groups are facing each other at a distance of 1200 to 1800 yards, and unless I am brought down like a stone by a direct hit by flak it must always be possible to crash-land the damaged aircraft in our own tank lines. The first flight therefore flies with bombs behind me in the only cannon-carrying aeroplane. So the attempt is made.
In the first attack four tanks explode under the hammer blows of my cannons; by the evening the total rises to twelve. We are all seized with a kind of passion for the chase from the glorious feeling of having saved much German bloodshed with every tank destroyed.
After the first day the fitters have their hands full, for the aircraft have been heavily damaged by flak. The life of such an aeroplane will always be limited. But the main thing is: the evil spell is broken, and in this aircraft we possess a weapon which can speedily be employed everywhere and is capable of dealing successfully with the formidable numbers of Soviet tanks. There is great rejoicing in the flight, the squadron, the wing and the group over this newly-gained discovery and its practical confirmation."
However, Rudel confirms that it's only possible to attack tanks outside the statical front, which is too well protected by AAA, and mentions that the cannon Stukas usually have to be escorted by bomb-carrying Stukas to take out the AAA in the vicinity of the attacked tanks as well as to foil attacks by fighters.
