It would appear that your "beef" is with the entire RAF, or at least the Air Force Board, and their apparent conspiracy to do away with the RN! Not too sure about that, way above my pay scale. I must at this stage admit to being light blue, I also have a very small brain - but heres a thought or two.
One of your arguements for doing away with the Nimrod is the stated low risk of hostile submarines in UK waters, not quite sure how that lines up with the predominant ASW role of the RN. I am no expert on the maritime world, just have a general servicewide grasp of such matters. However, how would you answer the question "DOES THE UK REQUIRE EFFECTIVE ASW FORCES?".
If your answer is yes, then provided the Nimrod is effective in ASW it has a role to play in the UKs armed forces. (The Nimrod boys on this thread all seem to be saying the MR2 is at least as effective as ASW helos, the MRA4 will be better still - AND THE NIMROD DOES A LOT MORE THAN ASW!!). If your answer is no then as well as doing away with the Nimrod (ignoring its other roles!) we can also do away with Merlin helos, Towed array frigates, and the ASW carriers that carry lots of ASW helos and your shiny Sea Harriers!
Personally I think the MRA4 should become the closest UK equivalent of the B-52, carrying shed loads of smart ordinance for use in a variety of different conflicts. (Yes I read Tom Clancy) It should have lots of loiter time, throw weight etc, all those good buzz words. The future is in smart long range weapons on more general purpose aircraft - converted biz jets would probably do. Maybe BEagles A400s could do it as a secondary role!!!??? But the Air Force Board won't wear that because they would probably have to give up some of their Tonkas in exchange - now that is a conspiracy for you!!
