Hornbills are large VTOL aircraft, each capable of accommodating either a full squadron of Striders or a certain number of Holons. They come equipped with ventral cargo doors and five hoist cables to effect combat drops and combat extractions without needing to land. Both Striders and Holons can make use of this system, although for the latter, the cargo bay is cramped due to their taller stature, which forces them to be in a crouched position during transport.
Hornbills have a total of ten jet engines, each consisting of a grouping of a large engine and two smaller engines on each wing and a grouping of large engine and small engine at each side in the back. The engine groupings can rotate at a 90° axis to allow hovering or vertical landing and take off.
Hornbills possess durable armor capable of withstanding fire from Union machinery such as Spider Tanks and Union Fighters, and are armed with missile pods that are implanted underneath their wings and have a chin-mounted turret.
