Lockheed Martin has delivered the first Sentinel A4 radar from Low-Rate Initial Production (LRIP) 2 to the U.S. Army and completed Phase I of Initial Operational Test and Evaluation (IOT&E), moving the program closer to full-rate production.
“This delivery is a major milestone in getting next-generation radar capability to the warfighter to address the threats of today and tomorrow,” said Rick Cordaro, vice president of Lockheed Martin’s Radar and Sensor Systems. “Sentinel A4 expands battlespace awareness and strengthens layered defense against cruise missiles, unmanned aerial systems, and rotary- and fixed-wing threats in complex environments.”
The first of 19 LRIP 2 systems builds on earlier Sentinel A4 deliveries and testing progress. During IOT&E Phase I, Sentinel A4 successfully integrated with the Army’s Forward Area Air Defense Command and Control (FAAD-C2), demonstrating the effectiveness of its open-architecture design and interoperability across multiple command-and-control networks.
Sentinel A4 will replace the fielded Sentinel A3 with a modern, 360-degree Active Electronically Scanned Array (AESA) radar designed to counter cruise missiles, unmanned aircraft systems, helicopters, fixed-wing aircraft, rockets, artillery, and mortars.
Lockheed Martin will continue delivering Sentinel A4 systems in support of the Army’s fielding plans and operational testing. These systems will help refine tactics, validate performance in real-world conditions, and ensure readiness for operational demands.
With decades of experience delivering advanced radar solutions, Lockheed Martin designs high-reliability systems for early warning, situational awareness, and integrated air and missile defense. Its radars feature common designs, mobile configurations, all-environment operation, and global deployment.
