UD4L Cheyenne
From Wikipedia, the free encyclopedia
The UD4L Dropship is a fictional dropship and tactical transport used by the United States Colonial Marines in the movie Aliens. It was derived from an original United Americas Department of Defense requirement formulated at the end of the Tienstin conflict. It acts as a gunship by using its own internal gun and deploying weapon pods and hardpoints for 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). 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.
