When attacking with airships your units get 3% extra defense against the enemy attack. When your kingdom is under attack, your units will also gain 3% extra defense, so long as you have airships. You can get a total of 15% defense, while you own (and/or send) airships in both instances of attacking or defending against attacks.

^* There is a formula to figure out the new time, Let's assume the skill at level 0, takes 2 hours. At level 1, the new time requirement to get to level 2 will be 1 + 1 * 2 = 4 hours. Let me break that down: New Skill Level (1) + 1 * Total Hours at level 0 (2) = 4 Hours.
