I think I have mentioned it before, but the day after the Nimrod 4 was cancelled, Liam Fox was interviewed on BBC Radio Scotland. I can't remember his exact words, but to paraphrase, he said that the UK still had an MPA need,but the Nimrod MRA4 was not the aircraft to fulfil it (due to the fact that they had no idea when it would actually enter service, or how much it would cost). He also said that they would look at the requirement when the financial conditions were better.
