The aerostats used in the TARS system are large fabric envelopes filled with helium that can rise to an altitude of 15,000 feet (4,600 m) while tethered by a single cable. The largest lifts a 1000 kg payload to an operating altitude providing low-level, downward-looking radar coverage.
The system features two tethered aerostats, roughly 77 yards (70 m) in length, that float to an altitude of 10,000 feet (3,000 m) for up to 30 days at a time. Each aerostat utilizes a different radar system—one has a VHF-band surveillance radar and the other an X-band fire-control radar.
Sky Dew (Tal Shamayim in Hebrew (טל שמיים)), or High Availability Aerostat System (HAAS), is a high altitude missile defense aerostat used by Israel Defence Forces since 2022. The radar system was developed by Israel Missile Defense Organization (IMDO) and the US Missile Defense Agency (MDA). It is a tethered blimp, developed by the US ...
A modern aerostat used by the U.S. Department of Homeland Security, the Tethered Aerostat Radar System (TARS) An aerostat (from Ancient Greek ἀήρ (aḗr) 'air' and στατός (statós) 'standing', via French) or lighter-than-air aircraft is an aircraft that relies on buoyancy to maintain flight. Aerostats include the unpowered balloons ...
The U.S. Army has developed a tethered aerostat to perform operational testing at Aberdeen Proving Ground beginning in 2015. The system, called JLENS, uses two moored balloons designed to provide over-the-horizon missile defense capability. Israeli missile detection system called Sky Dew, similar to TARS and JLENS, is in use from 2022.
The EL/M-2083 is an aerostat-mounted Airborne early warning and control radar.Another system of this kind is the Tethered Aerostat Radar System.. It is an early warning and control active electronically scanned array radar designed to detect hostile approaching aircraft from long ranges, especially when they approach at low altitudes.
The system employs a variety of sensors tethered from the blimp balloon system, and later evolved into other platforms, including fixed towers and relocated masts, which addressed logistical issues tested while on deployments.

Tethered Aerostat Radar System. Beginning in 1980 the United States installed a barrier line of tethered aerostats to detect low flying aircraft over Cuba and the U.S.-Mexican border, known as the Tethered Aerostat Radar System. [39] Israel developed a similar system, the EL/M-2083, which it sold to India and Singapore. [40]
