It would be still quite funny <| sep |> I ' m assuming they both get warning of the war at the same time . The time it takes to get an aircraft into the air hasn ' t significantly changed over the years . No but the speed of them has , depending on the distance the German craft could carry out a raid on the nazi airfields which are nicely full of readying planes , turn them into unusable masses of potholes and wreckage , return to base and be loaded out to engage the planes that did get into the air . And even if a bunch got through , WW 2 era bombing wasnt all that effective and anything flying low enough to be accurate would be vulnerable to a lot of ground based weapons beyond sam missiles Plus , Modern Germany has to make up their mind on what they are trying to accomplish . They only have 169 attack aircraft . Probably a third of those aren ' t operable . So more like 100 ready to go . They aren ' t going to be able to simultaneously bomb all the airfields in Nazi Germany and defend their own . See above , also see just how crazy powerful modern munitions are , it wouldn ' t take more than a a couple of planes to render an airfield uselessNazi Germany produced 67 , 000 tanks in WW 2 . Modern Germany only has about 500 including SPGs and not all of those are even operable . This is not even remotely a contest . The magic of modern technology only goes so far . The modern tanks would not even have enough ammunition to deal with all of Nazi Germany ' s Panzers . But the Panzers are physically incapable of dealing with modern armour and plenty of those tanks wouldn ' t even outgun q modern APC . Between that and the impossibility of supplying 60000 tanks and crew in the field any advance would be so severely limited as to not even be funny . Barely mechanized 67 , 000 tanks . Right . Not to mentioned outnumbered by 250 to 1 in personnel . Point to a single battle that has been won against worse odds . The infantry mostly still had to march the old fashioned way . Don ' t know about you but I ' d be pretty fucking tired after advancing that far on foot with a hugely congested supply line and attack choppers coming in at will during the night to kill whatever they please . The British did it all the time back when they first invented the machine gun . That ' s almost less of a technology two than this scenario . Personally I think he biggest thing you ' re missing is the sheer impossibility of supplying a force like this . Especially against a near omnipotent enemy that can strike at their supply chain at will .
