Sadly old chap 800 didn't have any Harriers. It maintained and flew those Harriers allocated to it by the Harrier role office at 1 Group which became HEPC (which stands for something I can't remember).
AOC 1 Group owned all the Harriers, the RN owned none.
I personally think this is sad. I think the fact that it'll be exactly the same with JCA is even sadder.
