Each race can produce three different types of fighter craft. In most cases these
designs include a light fighter, advanced fighter and a fighter-bomber design.
The feds have 2 types of attack shuttles and a advanced heavy fighter. Fighters
do not require any minerals to build. Fighters will defend the planet from attack
but can not leave the planet on their own without the support of a Air Attack Base.
Fighters can not be loaded onto ships without the aid of an Air Attack Base.
New fighters can be transported from planet to planet by packing them in an assault pod.
