QR4 Reconnaissance UAV

==Design==
The QR4 is designed for maximum air mobility, with a maximum ceiling of 75,000 feet and maximum air speed of Mach 3. It's roughly disc shaped, with the kevlar and aramid weave light armor giving it the appearance of a stereotypical UFO. The Reconaissance UAV is equipped with a multitude of sensors.
The QR4 is equipped with SPECTER technology, making it incredibly hard to detect across a wide spectrum of sensory methods.
==Armament==
The QR4 Reconnaissance UAV is equipped with a single .303 caliber light machine gun.
==Power==
There have been three series of QR UAVs, each one equipped with different methods of power.
===Hydrogen Engine===
The hydrogen engine is the standard means of power supply for the QR series UAV. It is highly efficient, but doesn't last as long as other methods.
===Remote Power===
Remote power is only used when the UAV is launched from a UNSC base or ship. This cuts down on weight, as the standard power supply can be removed.
===Fusion Reactor===
An experimental line of UAVs was created that harnessed the power of fusion energy. However, these were too expensive, and were eventually fitted with cheaper, less efficient power methods.
