The only Sturmoviks capable of carrying PTAB bombs are on the Type 3 and IL-2M3. These two types were built in late 1943 (at the earliest).
I'm in the process of making a campaign about the Kursk battle and in my readings I have found that the PTAB was first used at Kursk in July 1943. In my understanding, the only Sturmovik type savailable at that time were the single-seaters and the IL-2M-Early. The IL-2M-Late came out in August 1943, I believe, and this is the type that I'm using for the campaign (I know, but I'm only fudging it for just a couple months).
So, I believe that the PTAB should be included on the IL-2Ms, Early and Late types. This would make PTAB-carrying Sturmoviks available for the Kursk time period.
As of right now, I'd have to substitute a Type 3 in order to carry the PTAB.
