Excellent - so that is the short-medium range CIVILIAN requirement covered - now all we need to cover is the MILITARY (and possibly long-range civilian) requirement. That includes finding, fixing and FINISHing potential targets (including submarines). Globally. Something that the civvies cannot and do not do.
Is MAFF still called MAFF? I know they had a very close relationship with the MoD, with a MAFF guy often providing navigation training when onboard RN vessels because he was more qualified than anyone in the MoD. He's retired now, which must be a significant hidden cost to MoD.
Just sayin'. Civvies may not do it, but it doesn't mean they can't.
