The goal of the system was to allow the bomb to be guided to 100 yards (91 m) of its target after being dropped from a jet bomber flying at 50,000 ft (15,000 m) altitude.
Development was cancelled when it proved too large for a newer generation of jet-powered naval strike aircraft while the nuclear stand-off role went to the much longer ranged Blue Steel.
The low accuracy of bombing during World War II led most air forces to begin experiments with guidance systems.
The only fully operational devices were the German Luftwaffe's glide bombs, notably Fritz-X which was used against the Royal Navy with some success during 1943.
In 1946, the UK Air Staff published a report on the Control of Bombs which led to a November 1947 development proposal by the Royal Aircraft Establishment (RAE).
Initial design reports suggested a single weapon system could carry between 5,000 and 10,000 lb (2,300 and 4,500 kg) bombs as their payload.
The television had a square scanning pattern, but only the center was in sharp focus, representing a field of view about 55 degrees wide.
This started with normal aerial photography that was optically degraded to what they expected the television signal to look like at night when illuminated by flares.
To test these, the camera system was fit into the nose of WM262, a Gloster Meteor NF.11 night fighter, replacing the AI Mk.
Vickers test pilot Philip ("Spud") Murphy would dive the aircraft at 40 degrees to simulate the ever-growing image of the target that would be seen by the bomb aimer.
