High Frequency Radio Systems

The High Frequency Radio Systems program, managed by the Air Force, focuses on modernizing airborne communication by replacing outdated radios with the advanced AN/ARC-260 model. This initiative is essential for maintaining secure long-range communication across 1,300 aircraft within the US Air Force, Navy, and Coast Guard. The new radios will ensure compliance with Federal Aviation Administration requirements for transoceanic flights and address potential supply chain issues that could ground aircraft lacking this capability.

A primary goal of the program is to integrate digital, software-defined high-frequency capabilities into various aircraft platforms, including AC-130J, B-1, B-52, and others. The AN/ARC-260 radio will enhance communication reliability when satellite links are compromised due to environmental or man-made disruptions. It incorporates technologies like 3G/4G Automatic Link Establishment and features designed to minimize detection and interception risks.

In FY25, efforts will concentrate on developing a digital antenna coupler to replace the legacy analog version associated with the AN/ARC-190. This development is necessary because the existing coupler cannot fully support the processing power of the AN/ARC-260 radio. The new coupler will address these limitations and ensure sustained supportability as production of the analog coupler ceases by FY27.

The program's management involves collaboration between various entities within the Air Force Life Cycle Management Center at Robins AFB, GA. It includes contracting and engineering support from BAE Systems under a five-year contract initiated in December 2021. The transition from a Middle Tier Acquisition to a Major Capability Acquisition in 2024 underscores its strategic importance in enhancing airborne communication systems across military platforms.
