A couple of points:
Putting a different, or even worse, new radar into an aircraft is a huge project that would take a long time and would be massively expensive - so it ain't gonna happen.
People are very cynical (rightly) about MoD statements, but could I perhaps suggest that journalists perhaps aren't the best informed people and might have just heard a rumour in a bar or from a mate of a mate and tried to make a story of it. They may even - shock horror - embellish it to sound really dangerous! It might even be really old news!!!!!!!! Has anyone ever seen an article in a newspaper (such as the Telegraph) about military aviation that they new was absolutely correct (or even close)? Personally, I find that articles are written by civilians who have no understanding of military aviation, and are often factually incorrect. Example: GR4 crashes, photo of F3! It's not that hard, is it?
Sorry if this has gone onto an anti media rant, nothing personal Jacko,I'm sure your Jag articles are flawless!
