U.S. Army Receives First Five Sentinel A4 Air & Missile Defense Radars

The U.S. Army took delivery of first five Sentinel A4 radars on May 26, manufacturer Lockheed Martin announced Wednesday.

The Sentinel A4 radar has been on an accelerated schedule since the project was awarded in September 2019.

Lockheed Martin will 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.

The new air and missile defense radar will provide improved capability over the previous iteration, the Sentinel A3. 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 U.S. Army maneuver formations.
