1) Asturias, I was particularly referring to MQ-9s (Unit cost $30m+ - $56.5m when buying four with ground station and satellite link v Typhoon unit cost $125m + and of course the relative running costs)
2) The Ukrainians appear particularly to be vulnerable to the R-77 because of the tactics they are forced adopt as they don't have a BVR capability (Their R-27s require firing at altitude and pre-launch acquisition of the target by the missile seeker).
3) Ohrly, the 150km hit was a SAM presumably from an S-400, receiving a mid-course update from a networked Podlet K1 which is alleged to have supplied the final target data.
