Fighters that are damaged roughly lose around half their abilities @: attack: 2, defense: 2, Movement: 2, they also gain 5 damage points. The reason to this change, was so that players would feel more enthused to strategic bomb knowing they wouldn’t lose a fighter, instead, they could continue using the fighter just at a damaged level. The downgrade in its abilities would be a temporary result until the fighter is repaired at half the price (5 IPCs) of a new fighter.
Fighters that missed or didn’t get hit, are free to return to base like in the OoB rules.
One other thing i forgot to mention, bombers that are not accompanied with escorts are considered ‘locked on’ therefore are subject to interceptor fire @ 1d6 of damage per defending interceptor.
These rules make bombers and interceptors very powerful units. It encourages players to strategic bomb with 2d6 of damage, however there is also the risk of interceptor ‘lock on’ that would minimize the bombers full 2d6 damage potential.
