The US Army has taken delivery of its first five Sentinel A4 radars that will be used to detect and identify cruise missiles, unmanned aerial systems, rotary wing and fixed wing aircraft, and rocket, artillery, and mortar threats.

The STARE Project Office, US Army Sentinel Product Office received the radars from Lockheed Martin on May 26, 2022. The radar is developed and manufactured by the company in Syracuse, N.Y., and has been on an accelerated schedule since the project was awarded in September 2019.

“We are one step closer to getting this enhanced capability to our warfighters,” stated Leah Cook, Sentinel Product Director for the US Army Sentinel A4 program office. “The delivery of the first five radars is a result of collaboration and a continued commitment to the US Army.”

Lockheed Martin will now support the Army in the government test program phase into early 2023. The radars will undergo mobility, environmental, radar performance and logistics testing.

Production of the next five radar systems is already underway, and delivery is expected to begin in March 2023.

“Our team understands the criticality of this technology and the need to get it fielded,” said Mark Mekker, director of Army Radars for Lockheed Martin. “Our soldiers are in unpredictable environments, and the Sentinel A4 will provide improved eyes on the field to keep them safe.”

The new air and missile defense radar will provide improved capability over the previous iteration, the Sentinel A3. Lockheed says it will outperform the legacy radar, delivering improvements in contested environments against cruise missiles, unmanned aerial systems, rotary wing and fixed wing aircraft, and rocket, artillery, and mortar threats. This includes enhanced surveillance, detection, and classification capabilities to protect US Army maneuver formations.
