The UD4L Utility Dropship is the standard dropship type in use by NAU forces. It was derived from an original Department of Defense requirement formulated at the end of the Tienstin conflict. This versatile dropship is used as a tactical transport and as a gunship by using its own internal 25mm gun, deploying weapon pods and hardpoints for a variety of rockets and missiles.
The principle airframe is constructed from superplastic-formed diffusion-bonded metal matrix composites (MMC) and its 103.6 cubic meter internal payload bay can easily fit a M577 A.P.C. (turret stowed).
Its primary role is to operate from unprepared landing sites in support of ground forces and to transport the M577 into combat but it can also be used to carry up to 48 troops or cargo.
The engines can produce exceptionally high thrust for low specific fuel consumption. The UD4L Dropship is also called a "Cheyenne." It has AN/ALQ-2004E defensive systems to keep it well protected. It has two types of power plants to allow vertical take-off capability (VTOL) hover to the hypersonic trans-atmospheric.
The UD4L uses its turbines for normal flight, but uses scramjet for space travel and to escape a planet's atmosphere.
There are many variants the UD4 in service, some are specialized for the following missions: Troop Transport, Search and Rescue, Cargo Transport, Ambulance, Gunship, and Reconnaissance.
