Genstabler, my argument is largely based on the fact that ASW/ ASuW is a core competence of the RN and a large proportion of its manpower.
If UK PLC decides that it needs an MPA fleet then having one training stream for ASW/ASuW operators would seem to be the most efficient way forward. I'm not aware that the RAF has a training stream for those skill sets anymore?
Similarly the RN has no experience of flying and maintaining large multi-engine a/c so keep that with the RAF within JFP8.
JFP8 will primarily be a maritime asset, by definition, so OPCOM/OPCON of JFP8 would come under the appropriate JTF cell within "CinCFleet", surely?
