What if the Germans had operational V-1s in 1940? As I understand it, the V-1 was fairly crude and didn't have any ground-breaking tech holding it back, like the V-2 (or jet engines for that matter).
Let's say they had the V-1, maybe even with "portable" launchers (maybe some collapsible rail system mounted on a tank chassis, and a reusable RATO of some kind). The quick fall of France would probably preempt their introduction early (as well as unsuitable targets), but what about the BoB?
Intercepts would be very difficult. First the RAF would have to figure out what they were facing, and ways to combat them (diving attacks would probably be required to get the necessary speed to intercept), and raids to the French launch sites (and the problems in finding mobile sites) would tax the RAF resources. All this while the same conventional aerial attacks occurring IOTL would be happening simultaneously.
Would the V-1 be a game changer in 1940 or meh?
