Why does it have to be military?
You are fishing aren't you? That's not a serious question, is it?
Simply because no civvie companies do long range deep water ASW, even if they
might do
some medium range above surface surveillance.
But most importantly, the UK isn't in the game of using mercenaries to do the Finish part of Find, Fix AND Finish! (Is that the latest doctrine term or am I out of date again?).
