The Jet Windam is the GAT-04 Windam equipped with the AQM/E-A4E1 Jet Striker, a Striker Pack that improves mobility and grant flight capabilities in Earth's atmosphere, thus it is the mobile suit's standard equipment on Earth (although some Windams are seen using the old Aile Striker). With its flight capabilities, the Jet Windam has a distinct advantage over ZAFT's ZAKU series on Earth, possessing greater range, speed, and maneuverability. Furthermore, hardpoints beneath the wings can mount propellant tanks, along with a variety of additional equipment and weapons like missile launchers to bolster its offensive capabilities. The Jet Windam used by Neo Roanoke has the Jet Striker's various performance limiters removed or dialed back, allowing for increased output and higher speed.
