The gunship is suited for the role of an anti-tank aircraft. Its weapon loadout is focused on air to ground weaponary and is fitted with a capable hover engine for ground patrol missions. It is highly armored, but its weakness lies in its slowness and inability to attain the same speeds as other aircraft.
Fighter
The figher is designed the role of air superiority and excels at it. Its weapon loadout focuses on air to air weaponary such as three customizeable types of homing missiles, and its defensive capabilities are geared more towards outrunning an enemy than outlasting it.
Bomber
The bomber's main role is that of devastating enemy ground targets such as enemy bases and stationary vehicles. It is slow moving but contains defensive armor and anti-homing systems to ward off anti-air weapons long enough to conduct its bombing run. It also possesses a gunner turret for protection from anti-air fighters and light ground defenses.
Transport
The transport is the work horse of the modern military. Its main role is for transportation of vehicles and supplies and for carrying infantry to the front line. It is designed for quick pickup and dropoff by an actuated grip system that can acquire cargo crates and vehicles with only seconds spent on the ground. It's even capable of carrying armored crates filled with infantry behind enemy lines and dropping from a height providing safe distance from ground defenses. The ride may not be pleasant for the infantry, but it allows for them to be dropped off while inside protective cover compared to a parachute jump.
