I agree with Lordflasheart. There comes a time when you must stop modifying modifications. The AEW Mk7 was seen as a great success, and it was in a programme sense, succeeding against all the odds given how many fought so hard throughout to scupper it. (Including a signifcant part of the RN, MoD(PE) hierarchy, and AMSO/AML). But it was far more than the radar - which was not selected, but imposed by political over-rule. Searchwater upgrade didn't come close to winning the competition, and the company 'awarded' the contract didn't even bid. But some of the 'peripheral' elements were groundbreaking.
