Imagine all the resources of the rocket tech...............

..............Had been instead put into building more UBoats early on, what a difference that would have really made. The rockets while amazing and scary as hell, was a massive waste of manpower and resources for the German. They were really pinpricks on the Allies. Look how much carnage the UBoat crews caused with pretty small numbers and in many cases poor boats. The germans for sure threw away a war winning chance. Just imagine another 100 or so uboats, upgraded ones in the seas when the brits were struggling for there lives.
