TARS System - Tethered Aerostat Radar System (1978-Present) The TARS program is currently a counter-drug program funded by the Deputy Assistant Secretary of Defense for Counter Narcotics, Counter-Proliferation, and Global Threats. It provides an aerostat balloon mounted radar surveillance platform able to detect low-level targets along the United States – Mexico border, the Florida Straits, and southwest Puerto Rico regions in support of USNORTHCOMs and USSOUTHCOM's Counterdrug/Counter-Narco Terrorism (CD/CNT) missions.
In addition to the CD/CNT mission, TARS surveillance data also supports the North American Aerospace Defense Command's (NORAD) air sovereignty mission for the Continental United States (CONUS).

History
The TARS program began as three different Aerostat systems one run by the U.S. Air Force, one by the U.S. Customs Service and one by the U.S. Coast Guard. In 1992 Congress mandated a single system to be managed by the U.S. Air Force that would provide radar data to each of the stakeholders. Since none of the systems had gone through the formal acquisition process, support was almost nonexistent and the systems began to fail. At one point five of the eight sites had been down for 28 months. Dissatisfied workers and contractors complained to the DoD IG and an audit was conducted that surfaced the major issues and a management system was put in place.
By 2000 a standard system had been defined, contracted for and installations were beginning. The standard system included two different sized balloons, one 275K balloon and the rest as 420K ballons. The radars were standardized to the Lockheed Martin L-88 radar series. The first installation of the standardized system was at the Deming NM site in 2000.

The system operated under Air Force management until funding problems in the Department of Defense forced the Air Force to abandon the project to the Customs and Border Patrol (CBP) in 2013. The CBP continues to operate and maintain the TARS system with contractor personnel. The project is carried forward into the President's 2020 budget at 2019 levels.
