The US Army is initiating the installation of BAE Systems’ AN/ARC-231A Multi-mode Aviation Radio Set (MARS) on various rotary-wing aircraft, representing the first phase in a larger deployment of the advanced communications system. This new radio replaces the long-utilized ARC-231 radios that have been in service with US and allied forces.
The AN/ARC-231A stands out for being software-defined, which facilitates upgrades and the introduction of new features through software updates rather than requiring hardware modifications. The system comprises several components, including the RT-1987 radio unit, amplifiers, and mounting bases, specifically designed as direct replacements for older radio models. These radios support multi-band, secure voice and data communications, adhering to US, NATO, and international air traffic control standards.
Brian Shadiack, director of Adaptive Communications and Sensing at BAE Systems, highlighted the significance of this deployment, stating it represents a crucial milestone in equipping military personnel with enhanced communication capabilities, thereby increasing their readiness to face emerging threats. He emphasized that the next-generation, software-defined radio has gone through extensive testing to ensure top performance standards, reflecting a comprehensive understanding of the evolving needs of warfighters operating in a rapidly shifting environment.
This implementation is closely aligned with the Army’s Future Vertical Lift (FVL) program, which aims to modernize its aviation fleet by incorporating next-generation aircraft, sensors, and digital communications. A central component of the FVL initiative is ensuring that legacy helicopters, such as the UH-60 Black Hawk, CH-47 Chinook, and AH-64 Apache, can seamlessly integrate with future platforms and networked battle systems. The deployment of these software-defined radios is viewed as a vital step toward establishing an integrated communications framework.
BAE Systems has a proven track record in airborne communications, having produced over 100,000 radios for US and allied military forces. Earlier this year, the US Navy awarded BAE Systems an $85 million contract to manufacture additional Network Tactical Common Data Link (NTCDL) systems. These systems enable the secure and real-time transmission of voice, data, imagery, and full-motion video across multiple military platforms.
Additionally, in July 2024, the company secured $111 million in contracts to supply NATO-standard tactical radios for South Korea’s fixed- and rotary-wing aircraft. In March of the previous year, BAE Systems also received an $86 million follow-on contract from the US Navy to provide ongoing support for its Mobile Deployable Command, Control, Communications, Computers, Combat Systems, Intelligence, Surveillance, and Reconnaissance (MDC5ISR) programs. This five-year agreement encompasses engineering and technical services for both legacy and forthcoming MDC5ISR capabilities.
