US Army's attack helicopters to get fast-operating communications

The U.S. Army is set to enhance its rotary-wing aircraft communications with the integration of BAE Systems’ AN/ARC-231A Multi-mode Aviation Radio Set (MARS), a next-generation, software-defined radio system. MARS has completed initial installation and testing, proving operational readiness for select attack helicopters. This advanced system offers multi-band, multi-mission capabilities with Type 1 cryptographic modernization, enabling secure and fast communications critical for mission success. Its software-based architecture allows for flexible upgrades and mission-specific modifications through software-only updates, addressing evolving battlefield communication needs efficiently. MARS serves as a drop-in replacement for the legacy ARC-231 radios currently used by U.S. and allied forces, emphasizing configurability and interoperability for joint operations. It supports international air traffic control communications and complies with U.S. and NATO standards. Manufactured in Fort Wayne, Indiana, with engineering support from Florida, the system is part of a $460 million, five-year contract awarded by the U.S. Army
