Air Combat
There is an air combat phase at the beginning of each game round.

1. Each side moves their aircraft
2. A dogfight occurs, with aircraft firing at their dogfight values
3. Surface attacks and strategic bombing raids occur

Types of Aircraft
Air superiority. These include fighters, advanced fighters, and jets. Aircraft of this type can only destroy enemy aircraft. Never land or naval targets. But in this role they excel. These are your main defense against enemy bombing attacks.
Dive bombers. These planes are excellent at destroying land targets, and are normal at destroying enemy surface ships. If you gain air superiority, you can use your dive bombers to do serious damage to an enemy army.
Torpedo bombers. These planes are excellent at destroying enemy surface ships, and are normal at destroying enemy land targets or subs. Gain control of the skies, and you can use your torpedo bombers to sink enemy ships and subs.
Medium bombers. These planes are a jack of all trades, master of none. They are normal at attacking enemy land units, surface ships, or subs. They do 2 PUs of damage when strategically bombing. They allow you to strike targets beyond the range of your torpedo bombers or dive bombers.
Strategic bombers. These planes do 5 PUs of damage when strategically bombing. This is their primary intended purpose. If an enemy lacks sufficient fighter protection, you can use your strategic bombers to impose real economic damage.
