Tech 2 Air Unit
T2 Air units are the most common air units. At this tech level, all Factions get a Gunship, a Torpedo Bomber, and a T2 Transport. They are more powerful than their T1 counterparts, and while they are not as powerful as T3 air units, they are much cheaper and quicker to build.
The energy drain rates are double that of their T1 counterparts, despite the resource to time ratio being the same, due to the build rate of the factory being doubled at T2. Either a ring of T1 or a T2 power generator is usually required to produce T2 air units effectively. If following the latter route, due to the higher energy upgrade cost of the air factory, a land factory or the ACU is usually upgraded to T2 first.
