Radar to Provide Enhanced Air Defense

New air and missile defense Sentinel A4 radars will provide US soldiers with a more secure warfighting environment, improving capabilities against multiple evolving threats. The US Army Sentinel A4 Program Office provided an accelerated contract award to Lockheed Martin to begin production for five additional radar systems. 

The systems are developed specifically to detect and identify cruise missiles, unmanned aerial systems, rotary-wing and fixed-wing aircraft, and rocket, artillery, and mortar threats. 

Army soldiers will use these radars to evaluate the operations of the new Sentinel A4s, which are projected to be delivered by the end of 2022.

Even though the initial Sentinel A4 contract for 18 radars was awarded only two years ago, the Sentinel A4 team already completed production of the first A4 system this summer. 

The first five systems of the original contract are expected to be delivered to the U.S. Army in March 2022.

Open architecture is the cornerstone of the radar system’s design and will allow for future upgrades that not only extend the life of the radar, but also address evolving threats over the next 40 years. 

The $281 million contract to develop the Sentinel A4 system was awarded to Lockheed Martin in September 2019. Their improved capability includes enhanced surveillance, detection, and classification capabilities to protect U.S. Army maneuver formations, according to armyrecognition.com.
