Ground-Based Air Surveillance Radars

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 SSR 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.

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.
