IN A NUTSHELL
  • 🚁 BAE Systems introduces the AN/ARC-231A MARS, enhancing secure communications for U.S. Army helicopters.
  • 🔧 The MARS system allows for flexible integration and mission deployment with advanced configurability.
  • 🌍 Over 100,000 radios globally deployed, showcasing battle-proven communication technology from BAE Systems.
  • 🔒 Rigorous testing ensures high-performance standards, meeting evolving needs in military operations.

In a significant advancement for military technology, BAE Systems has successfully integrated the AN/ARC-231A Multi-mode Aviation Radio Set (MARS) into the U.S. Army’s rotary-wing aircraft. This next-generation communication system is designed to enhance secure, fast-operating communications in fighter helicopters. With its software-defined radio capabilities, the MARS system promises to revolutionize military communications by allowing for flexible integration and mission deployment. As the U.S. Army continues to adapt to rapidly evolving threats, the MARS system provides a critical upgrade in ensuring mission readiness and operational effectiveness.

MARS System Offers Advanced Configurability

The MARS system, serving as a drop-in replacement for the original ARC-231 radio, emphasizes configurability and flexibility. This feature ensures seamless integration and interoperability across joint force operations. The system is available through foreign military sales, offering international compliant air traffic control communications and a comprehensive range of U.S. and NATO capabilities. According to BAE Systems, the MARS system is part of their extensive portfolio, with over 100,000 radios deployed globally, showcasing their battle-proven communications technology.

Manufactured in Fort Wayne, Indiana, with engineering support in Largo, Florida, the MARS system represents a significant enhancement over legacy products. Its compact radio sets provide multi-band, secure anti-jam voice, data imagery transmission, and network-capable communications. The U.S. Army’s contract with BAE Systems, valued at $460 million over five years, underscores the importance of this technology. This agreement includes hardware components, repair services, engineering and logistic support, and further development for rotary-wing aircraft.
