Well it is actually about 3 miles away, but i get to see it every time I go out my door. The radar equipped JLENS aerostat will fly at an altitude up to 10,000 feet above sea level, giving it a much longer detection range than ground-based radars, providing radar coverage up to 340 miles – an area which includes the National Capital Region (NCR). Input from JLENS will also feed to the 263rd Army Air and Missile Defense Command, to increase decision time in defending the airspace over the NCR. The aerostats will fly 24 hours a day, except in times of severe weather or required maintenance. The system’s ground elements include a mobile mooring station, radar and communications payloads, a processing station, and associated ground support equipment. Aberdeen Proving Ground was chosen as the exercise location because it provides coverage over the NCR, has sufficient ground area for the two JLENS aerostat sites, and controls its FAA approved restricted airspace, which supports the exercise without interfering with the mid-Atlantic coast air traffic corridors.
