Anyway there was a brief flurry of interest at Fanrbourough last year when QinetiQ, Thales and Textron announced they were submitting a bid utilising the funny little Scorpion as their solution to the puzzle no-one had previously heard of:

"The UK Ministry of Defence is developing a complex set of aggressor-type training requirements for all three of its armed services, with the ambition of developing a "Red Air" capability via its Air Support to Defence Operational Training (ASDOT) programme."
Today we find out that Inzpire and Discovery Air Defence have joined the fray.

From the press release you could be forgiven that they'll be offering clapped-out Vietnam-vet A-4s as part of their "solution". But the actual words don't mention anything about A-4s so that would just be jumping to conclusions.
Who knows? How exciting.
