*sigh*...the v1 and v2 were fire and forget weapons, not designed for aerial targets or even precision strikes like would be required to hit tanks...based on realistic usage, what good would they do in the main arenas?
The V1 was designed to end its flight over London.
Had london been further away, or closer, the path and destination WOULD have been changed so that they still ended up at the same target.
Also, not all V1 sites were in the same area. Some were quite geographically remote. Yet they still all ended up in London.
They ARE programmable. So to speak. You CAN change them so they hit the proper point you want. Yes they were fire and forget, but were by no means unstoppable. A large effort was put into place to stop them, and many were intercepted by ack and by fighters.
