Reading on the subj. It shows that as the Thunderbird was the more mobile solution for the army, and that Royal Navy had their version: The Sea-Slug missile, with spec's much like the Thunderbird.
Picture-surfing seems to reveal that the main body of the Bloodhound had fin's/planes in only one plane, where the smaller versions had fin's in X-plane. Hence, to my relief, the pictured is indeed a Bloodhound!
[and yet I've found pictures of 'just wing' Bloodhounds too, without being able to find the difference described - Probably it's the primary MK.1 wich had four midship stabilizors in a X :-/ ]
I have been impressed by following details of acceleration of the Bloodhound, wich presumably is representative for most SAM's:
"By the time the missile has just cleared the launcher it is doing 400 mph. By the time the missile is 25 feet from the launcher it has reached the speed of sound (around 720 mph). Three seconds after launch, as the four boost rockets fall away, it has reached Mach 2.5 which is roughly 1,800 mph" :-o
