Golf Bravo Zulu, thanks for that info,didn't know two different manufacturers.
Tho saying that did Airfix get their facts wrong as that Bloodhound on the packet looks more like Thunderbird than Bloodhound.
Remember there were three radars used with it. One for horizon,one for azimuth and one for putting a tracking beam upto the aircraft. Used lots of uprated Meadows 27KVA which were 30KVA.Great when the air start worked but a bugger to hand crank. Synchronising them was also an art.
Think test firings were done at Pendle sands and Benbecula ranges.
