The AN/TPS-70 is a highly mobile, three-dimensional (3D) air surveillance radar developed by Northrop Grumman for the U.S. Air Force and allied nations. Designed as an all-weather, long-range system, it plays a vital role in tactical air defense, providing precise detection and tracking of aircraft, missiles, and unmanned aerial vehicles (UAVs).
Originating in the United States, the AN/TPS-70 is part of the TPS radar family, succeeding the earlier AN/TPS-43 model. It operates in the S-band frequency range, offering robust performance with advanced electronic counter-countermeasures (ECCM) and high-resolution 3D target data.
Equipped with a phased-array antenna, the radar provides a detection range of up to 240 nautical miles (approximately 445 km) and can track over 500 targets simultaneously. Its digital signal processing capabilities enhance detection accuracy and reduce false alarms, even in cluttered or jamming-prone environments.
Mounted on a mobile tactical vehicle, the AN/TPS-70 can be deployed rapidly in field conditions and integrated seamlessly into NATO air defense networks. The radar also supports Identification Friend or Foe (IFF) systems, contributing to situational awareness and joint-force interoperability.
Its proven reliability and adaptability have led to widespread deployment across multiple nations, including the United States, Chile, South Korea, and Turkey, among others.
The price of the AN/TPS-70 radar system varies based on configuration and integration requirements but is generally estimated between $8 million and $12 million per unit for export or modernization contracts within the United States and allied markets.
It offers a detection range of approximately 240 nautical miles (445 km).
