I am playing the spy mission (second in campaign?) and I have noticed that my starbase, which suppose to give +1 defence bonuses in all catigories, does not give it to the ships in range. Do the ships need to have some shields in order to recieve bonus? Does it increase only available shield (like if ship has anti-missile shield, then only anti-missile shield gets bonus)? If any of this true, I think the explanation needs to be present in the description of the base upgrade.
