US Air Force Accepts First TPY-4 Radar From Lockheed

The US Air Force has taken delivery of its first TPY-4 radar from Lockheed Martin after the system successfully completed early phase testing.

The radar delivery is part of the Three-Dimensional Expeditionary Long-Range Radar program, under which the service aims to modernize its air surveillance capabilities and replace its aging AN/TPS-75 systems with an order of up to 35 TPY-4 radars placed in 2022.

With 360-degree coverage, the fully digital, long-range, ground-based radar can detect and track a wide range of aerial threats, ranging from tactical ballistic missiles, aircraft, low-flying targets, and small drones, operating effectively in extreme environments.

It comes in fixed and mobile variants, allowing it to be transported via C-130, C-17, or helicopter, in addition to truck or rail. 

“The successful completion of early phase testing and delivery of the first TPY-4 radar system underscores our dedication to providing the US Air Force with cutting-edge, high-performance systems that meet their evolving requirements and expectations,” said Rick Cordaro, company VP of Radar and Sensor Systems. 

“The 3DELRR program is of the utmost importance to air surveillance and defense capabilities worldwide, as well as defending the nation.”

Norway is the first international customer of the Lockheed radar, having ordered eight in 2022 and an additional three in September 2024.
