Tethered at up to 3,000 metres above their ground- or sea-based mooring pads, aerostats located along the southeastern United States provide unmanned platforms for coastal and sea surveillance, particularly directed against illicit drug trafficking. LASS, a Low Altitude Surveillance System, with its L-band radar can detect and track low flying aircraft (60-m altitude) to a range of over 240 km.
