Lockheed Martin has won an accelerated contract award to produce five additional Sentinel A4 radar systems for the US Army.

Value of the contract has not been disclosed. It was awarded by the US Army Sentinel A4 Program Office.

The radars will provide significant upgrades to the current Sentinel capability. US Army soldiers will use these radars to test the upgrades in the new A4 variant.

Sentinel A4 is a high-performance missile defence radar designed as a replacement of the legacy Sentinel A3 (AN/MPQ-64A3) air and missile defence radar.

The radar also has enhanced surveillance, detection, and classification capabilities to protect manoeuvre formations of the US Army.

All the Sentinel A4 missile defence radars are expected to be delivered by the end of next year.

US Army Sentinel A4 program office programme manager Troy Allen said: “The Lockheed Martin team truly understands the importance that this system holds for our warfighters.

“Once equipped with the Sentinel A4, our soldiers will operate in a more secure warfighting environment, improving capabilities against multiple evolving threats.”

Sentinel A4 radar can provide RAM Point of Origin (POO) and Point of Impact (POI) locations. It also provides additional protection against electronic threats.

The initial Sentinel A4 order to develop the Sentinel A4 system was awarded to Lockheed Martin in September 2019. The order comprises 18 radars.

However, the Sentinel A4 team already completed the production of the first A4 system this summer. This is five months ahead of the original schedule.

The US Army was originally expected to receive the first five systems of the initial contract in March next year.

Lockheed Martin Army Radars director Mark Mekker said: “This latest contract was awarded two years earlier in the development process than in previous programmes, thanks to the team’s continued success in meeting all milestones ahead of schedule.

“It’s not only representative of the hard work of our employees, but also the US Army’s confidence in the experience and performance of Lockheed Martin.”
