I was thinking of allowing fighters to intercept w/ radar along w/ the bonus to AA.
Correct me if I’m wrong, but before British radar stations were fully operational, the Germans could achieve relative surprise, as they would constantly change their attack routs, thus RAF interception was rare, and almost required an unlucky running into a patrol. It was not until radar stations were fully operational that fighters could be directed directly to intercept the Luftwaffe.
Also, it wasn’t long after the Germans discovery of Britain’s advantage that they established their own radar defenses, which considerably contributed to the high casualty rate among allied bombers.
Thus, I think adding fighter interception to the radar tech effectively demonstrates it’s historical key role in the development of a defensive air combat command and control.
Finally, I’ve heard some say that radar is too weak, since “AA never hits anything anyway”. Besides, the enemy can always counter w/ fighter escorts.
