The R2Y2 jet as far as I know never left the drawing board. I know the Dev’s are not great at historical accuracy, but I am not sure a mythical plane that was never produced is going in the right direction.
Stats are one thing and real performance is other complete diferent. Worst armour than Jumbo and a weaker cannon. If we dont see Jumbo and 76 variant what are supposed to do with a weaker tank in general?. You can kill it at tier 3, the game shows you where to aim and the sides are weak, plus TNT, Explosive charges, mines and planes, just pic up one to destroy it.
Does this even matter? Both canons have zero chance against Panther, while their armor making them immune to Panzer IV but Panther will defeat them both.
Gameplay is pretty much the same, unless Churchill wont have that stupid MG port weakness.
Technically Tiger will be able to pen Churchill but not Jumbo - but why play Tiger when Panther has a better gun and better armor.
Churchill VII does not have an APHE, which means it is difficult to destroy enemy tanks, and Churchill’s movement speed is slower.
For the most common Panther of BR IV, Churchill’s vertical armor is easier to penetrate than inclined armor
