Hitler messed up a bunch of projects but you're exaggerating. Come on now...Except those belonging to USA,which never get targeted.
But,as i mentioned earlier,as long as Hitler lived more factories do not mean more useful stuff,but stupid things like Mouse or V2.
Well,V2 was good for future satellites,but as weapon it was joke.Just like V1.
Even sensible ones,like Me 262,was partially ruined by Hitler,who want turn it into bomber....
But,it would be funny TL,with germans using Mouse and other shitty weapons.
262, even if everything went according to plan, would've been limited by jet engine production as while it was MASSIVELY streamlined within a short amount of time, was still exceedingly difficult for Germany due to a lack in factories, resources, and manpower.
