The 3.67-meter, 75-ton Advanced Electro-Optical System telescope is the largest telescope in the Department of Defense used for satellite tracking. The telescope moves fast enough to track low-Earth objects such as satellites and missiles, while also tracking man-made objects in deep space and performing space object identification data collection.
