Mmm, of all the issues going on in defence post SDSR this one is rather, erm, irrelevant/childish/ a wind up?! .... delete as required!
But to humour such a question.... in order to get rid of the navigators - or Weapon Systems Officers as they are now called (take note of the name - it gives a clue as to how much navigating the back seaters do nowadays!) - you would have to do one of the following....
- Take the GR4 out of service
- Complete a major modification to the GR4 fleet (and I can only imagine how major!) to remove all the systems from the back seat and put em in the front or...
- Just keep things as they are for the next few years until you have a force of Typhoon and JSF as is the plan and then the issue is resolved.
I think that those who are bored enough to read your post - as I am sitting waiting on the snow to melt such that I can escape my house - will go for the latter, as is the plan at the moment anyway.
Innit
