Rather expensive way of dealing with a rather cheap problem. Let’s hope it doesn’t become a standard way of dealing with low tech threats - we need to think about how we do GBAD properly or we’ll be bled to death when our opponents realise they don’t have to engage us face to face to erode our capabilities.
CWIS and a decent radar as well had in Basra would be my starter for 10 for point defence which is what the C-UAS threat relates to. And a re-writing of doctrine: enemy use of UAS mean we no longer have air superiority let alone supremacy. Favourable Air Situation is now as good as it gets.
