When the Computers and displays were replaced on Bloodhound 2 in 1986-89, they did include data links that allowed the whole system to be digitally integrated with itself along with command and control functions being carried out at Flight, Squadron and Force level. I do believe it was also going to be integrated into IUKADGE, but of course that didn't become operational until long after Bloodhound was canned.
Back in the '80s, I remember being tasked with "Voice Control of SAM" while working Neatishead from the NAEW E-3A. It sounds more interesting than it was, as the control just consisted of a track voice tell format which was usually responded to by a very bored "Roger" from the ground unit.
