OK so then radar shouldn't give any bonus to shoot down or invalidate long range AC?
How do you see heavy bombers and increased industrial production working without one invalidating the other?
Each technology can always make a original unit better, It does not deflate the abilities of another. Of course HB and having better production efficiency are cases where both bombers and factories have greater uses, but in this case they dont directly deny the abilities of the other. The damage potentially from bombers is still the same.
The games design does not process any aspect where: "hey i got rockets, so your other tech is now modified by the fact that i have this weapon"
Radar should only ADD to the ability of AA guns to shoot planes, or provide a defensive benefit like the ability to scramble fighters from adjacent territories to defend the SBR target with interceptors.
AS for the capabilities of the English jet aircraft.
The RAF initially reserved the aircraft to counter the V-1 flying bomb threat with No. 616's Meteors seeing action for the first time on 27 July 1944 with three aircraft active over Kent. After some problems, especially with jamming guns, the first two V1 "kills" occurred on 4 August. The Meteor accounted for 14 flying bombs. The anti-V1 missions of 27 July 1944 were the Meteor's (and the Royal Air Force's) first operational jet combat missions.
14 kills of over 5,000 V1's sent ( about 2300 were shot down by non jet planes) does not make any case for Jets as a superior vehicle to destroy 'rockets' At least to model any potential modifier for these planes shows no research to validate that modifier. Not to mention the V-2 had no counter weapon.
