At work.
Well.... unsure as to the engined Dora.... but there's bound to be a few changes to time tables of things like the timing of the Kursk offensive. That's if the bulge forms and I doubt the introduction of the VK will change things that much for it not to.
So... more German tanks and less delay in attack at Kursk giving the attackers more of an advantage over the defenders?
More and heavier tanks (For a relative value of 'Heavier') should help the German side over the Russians generally any-who.
Not sure about Rommel's situation, though.....
Well with our friend 'wiking' clearing the Kursk thing up. (Which he did nicely) I do believe that it is safe to assume that, even with the battle of Kursk being a loss, with more tigers on the eastern front, the Russian's advance could be seriously slowed down. But in the end, I believe that the war would have still ended in a German defeat. (But it is possible that with the Russain advance being slowed down, that it might have been the Americans or British to be the first march into Berlin.)
Rommel is a different story, though.
The Africa campaign by 1942 was mostly being won by the number of men one had and it was sorta looking good for Rommel at the time:
Originally, Rommel had received 31 Tiger H1s for his campaign, but with there being more VK 4501 Ps being there, Rommel would have had an easier time. Proven by the article that I found on this subject:
"March 1941. Four of the pre-production Tiger (P)s are allocated to the Afrika Korps and unloaded at Benghazi in mid April 1941. It takes three weeks for them to reach Tobruk and be prepared for battle, by which time one of them breaks down beyond repair, and is cannibalised to keep the others running. Of the three Tiger (P)’s which begin the assault on 4 May 1941, one is immobilised by mines, and one has its track blown off by a 25 pounder artillery shell. But the last one breaks through all the enemy defences, followed by the Panzer IV’s and III’s and the lighter German tanks. The counterattacking British Cruiser IV’s and Matilda II’s can’t even dent the mighty Tiger (P) with their puny 40mm (two-pounder) guns, and one by one are blown into scrap. Tobruk falls in May 1941, and Rommel prepares to continue the advance into Egypt. "

The only difference between the article from above and our discussion is that the scenario has the VK 4501 P available by 1941. But I think that our dear Rommel would have taken advantage of the newly acquired, say, 11 VK 4501 Ps. With such a large force of self-driven 88mm gun panzers, we can assume that Rommel would have shot Montgomery's tanks before they had even got close to the 4501s. In other words: Montgomery's hill defence strategy used in 1942 would not have worked as well as intended.
Please tell me if I may have gotten anything wrong.
