I yet have to see an AI airship (or privateer)or wait for flight, upgrade it to a fighter, put it intercept mode and watch it destroy all the AI's airships.
Also why the Civpedia says they are good against ships? There are no bonuses listed vs navy units in the description.
Would anyone know how that changed ?
Is there a way to bring airships to attack the enemy continent?
When talking about upgrade to fighters - the fighters have 100% chance to intercept and there are 2 more upgrades; is this to compensate the evasion skill of the defender?
AIs love airships in my experience. Perhaps you rarely allow them to reach physics.
