A couple of thoughts
Wrath
"The only thing is with no navigators who will fill the majority of the $hitty staff jobs - because you can bet on the fact that there won't be a reduction in the number of SO1/2/3 'flying branch only' staff appointments!"
I suspect the re introduction of commissioning for WSop's may help out here

"The point about aircraft-age is not true - yet. There will always be a role in MR aircraft"
I am pretty sure, but happy to be proved wrong, that I read on a recent thread in here that at Kinloss they were using WSop's to overcome the shortfall of WSO's
GPMG
"So these 'black boxes' have replaced the Nav?
I hope that any future enemy does not have the capability of taking out the technology that those black boxes depend on"
As the Nav was only ever a block box interface, we have now made the black boxes more intelligent and we have trained the rest of the crew in how to use them, so I am not sure quite what your point is?
