Raytheon [RTN] said Thursday it has received a $406 million contract to continue providing hardware support and software upgrades for Army aircraft radio systems.

Under the contract, originally awarded on Feb. 7, Raytheon will support upgrades for up to 5,000 of its ARC-231A Skyfire radios currently used on the Army’s UH-60 Black Hawk, UH-72 Lakota and AH-64 Apache helicopters.

“These radios are the backbone of rotary-wing communications. The ARC-231A enables U.S. forces to maintain the edge in secure communications, whether they’re flying in contested or congested environments,” Barbara Borgonovi, Raytheon’s vice president for integrated communication systems, said in a statement.

Raytheon was the only company to submit a bid for the work.

The ARC-231A radios are software-denied and designed to more easily introduce upgrades without having to remove the systems from its platform.

Work on the latest deal is expected to be completed in December 2023.
