Flamingo FP-5 cruise missile: launched from a simple ramp, range of 3000km's, payload 1000kg's.
Accuracy +/- 14m (meters) now in the hands of the Ukrainians. 9 months to develop. Way ahead of decrepit Russian technology.
Current production is 1 per day. Plans to build 200 per month by October. It's not sure how much efficacy there is in the production numbers but it is a potential game changer.
One thought: at what point (if there is) does the continued destruction of gas and oil plants affect Europe's energy needs?
