> Automatic gunlaying (using, among others, the SCR-584 radar) and the proximity fuze played an important part in Operation Diver, (the British operation to counter the V1 flying bombs). Both of these had been requested by AA Command and arrived in numbers, starting in June 1944, just as the guns reached their free-firing positions on the south eastern coast of England. Seventeen per cent of all flying bombs entering the coastal 'gun belt' were destroyed by guns in the first week on the coast. This rose to 60 per cent by 23 August and 74 per cent in the last week of the month, when on one extraordinary day 82 per cent were shot down. The rate increased from one V-1 for every 2,500 shells fired to one for every hundred. https://en.wikipedia.org/wiki/SCR-584_radar#Operational_use https://en.wikipedia.org/wiki/SCR-584_radar#Operational_use > 90mm anti-aircraft guns were normally operated in groups of four, utilizing the SCR-584 microwave computer and being controlled by the M9 Director. The SCR-584 was accurate to about 0.06 degrees (1 mil) and also provided automatic tracking. Direction and range information was sent directly to the M3 Gun Data Computer, and M9 Director, which directed and laid the guns automatically. All the crews had to do was load the guns. https://en.wikipedia.org/wiki/M9_Gun_Director https://en.wikipedia.org/wiki/M9_Gun_Director
