The Air technology research tree is used to unlock and improve different types of aircraft. The aircraft are divided into three different types of airframes: light, medium, and heavy, as well as their jet counterparts. Each type of aircraft built upon light airframes also has a carrier variant that can be researched. These variants are able to launch from and land on aircraft carriers.
