Oh, that disater was a procurement at its absolute worst F10..
A great example of pointless duplication of effort and horrendous waste of money.
However, the Government was largely to blame there, first the programme should never have been embarked upon (AWACS bought off the shelf).
Second, the MOD kept changing the specification, this resulted in the avionics being in a constant state of modification, that resulted in costs spiralling out of control until the plug was eventually pulled.
I have some pics somewhere of some of the prototype AEW Nimrods on the dump at Abingdon.
Let's not even discuss the Nimrod MR4A!
