Ground-Based Air Surveillance Radars

Multi-mission capable with the ability to simultaneously detect ultra-low to high altitude targets while performing its normal surveillance mission; Lockheed Martin’s long range and medium range radars set the industry standard for ground-based air surveillance. With more than 60 years of experience developing and delivering ground-based radar solutions to our customers, our high-performing, high-reliability, solid state radar systems specialize in early warning, situational awareness, tactical ballistic missile surveillance, and defense. Our radars are designed with the highest degree of commonality and fully integrated Solid State Radar systems. They can operate in all environments, are available in highly mobile configurations, and are deployed worldwide.

It’s why Lockheed Martin ground-based air surveillance radars are the choice of more than 30 nations on six continents.

Our family

TPY-4

Developed to include all the mission capabilities our current product family offers, our next generation long-range multi-mission radar system includes significant technology investment (including GaN) for enhanced capabilities to address emerging threats. Updated technology components backfit into existing product base. TPY-4 is easily scalable and is available in both fixed and highly mobile, transportable variants.

TPS-77 MRR

The Multi-Role Radar (TPS-77 MRR) is designed for ultra-low power consumption and is a highly mobile version of Lockheed Martin’s successful TPS-77 product line. This high-performing radar, configurable for long and medium range, is more transportable than the TPS-77.

AN/TPS-77

Designed to be a multi-mission radar, the TPS-77 incorporates the best AN/TPS-59 and FPS-117 features to create an economical, high performing, fixed or mobile radar that can be transported via C-130, C-17, truck, rail or helicopter.

AN/FPS-117

Developed for the U.S. Air Force, it provides long-range surveillance capability to the minimally attended Distant Early Warning line in Alaska and Canada. It is the most capable dual-use air traffic monitoring and air defense radar available and has been proven in more locations around the world than any other radar in its class.

AN/TPQ-53

Developed for the U.S. Army, the solid-state phased array AN/TPQ-53 radar system, or, Q-53, detects, classifies, tracks and determines the location of enemy indirect fire in either 360 or 90 degree modes. The radar system’s active electronically scanned array (AESA) provides the foundation for multi-mission capabilities. The Q-53 has demonstrated the ability to identify and track unmanned aerial systems (UAS), showing the capacity to incorporate air surveillance simultaneously with counter target acquisition in a single sensor.

AN/TPS-59

Developed for the U.S. Marine Corps to provide a mobile long-range surveillance radar capability. It is recognized as the world’s most capable long-range ground-based radar for tactical ballistic missile defense with proven performance during live fire tests.

Sentinel A4

Sentinel A4 is a high-performance replacement of the legacy Sentinel A3 air and missile defense radar that will provide significant improvements to the existing Sentinel capability against cruise missiles, unmanned aerial systems, rotary wing and fixed wing threats. The Sentinel A4 will add the ability to detect Rocket, Artillery, and Mortar (RAM) threats, providing RAM Point of Origin and Point of Impact locations, while also providing added protection against electronic threats.

Upgrades, Maintenance and Services

For TPS-77, FPS-117 and TPS-59 Long-Range / Medium Range Air Surveillance Radars

The open architecture and continuous production of our radar systems has allowed for investment in the development of obsolescence replacements and enhancements, allowing our customers to extend the life of their systems far beyond the original designed life expectancy.

We've Got You Covered

The threats to military and civilian assets are accelerating in volume, diversity, and ferocity every day. In this frenetic environment, the U.S. military and its allies need radar systems that can protect various mission types and adapt to an ever-changing landscape.
