-#

defender's radar research level

Strategic bomber v. bombing targets:

+1

for each attacker strategic bomber research result beyond that needed to construct strategic bombers

+1

for every eight (Europe) or four (Pacific) hexes of excess bombing range (as limited by the number of strategic bomber research results - 26.461B)

-#

defender's air defense research level

Bombing targets use the SW Combat Table row equal to the defensive strength of the target, which is the total of the following:

1

each flak factor, airbase counter, objective or anchor symbol

2

each city or port

1

each fortification level (+1 for each fortification; +2 for a fortress; beach defenses have no effect on air defense levels)

+ modifiers favor the attacker and - modifiers favor the defender. The net modifier for both SW combat dice rolls is always the same, except one is positive and one is negative.
