Executive Summary
This technical report proposes research to determine the necessary High Frequency (HF) radio infrastructure to support combat operations in a satellite-denied environment. It aims to ensure battle space awareness, assured command and control (C2), and integrated fires through HF beyond line of sight (BLOS) networks. The study focuses on operational and strategic levels, envisioning robust HF networks for prolonged combat with a peer adversary.
Why It Matters
This document is crucial for defense analysts as it outlines the strategic imperative and technical solutions for maintaining critical communications in a satellite-denied environment, a key vulnerability in modern warfare. It details the evolution and future of HF radio as a resilient alternative to SATCOM, directly impacting operational planning and force readiness against peer adversaries.
Key Takeaways
- HF radio is being revitalized as a critical backup for Command and Control (C2) in satellite-denied environments, moving beyond its traditional role.
- New technologies like Wideband HF (WBHF) and systems such as URG-IV significantly increase HF data rates and user-friendliness, making it viable for more complex data exchange.
- The US Navy is actively upgrading its HF infrastructure (e.g., BFTN to BRSE) and training to ensure operational readiness for prolonged combat without satellite communications.
- The document highlights the importance of HF communications in a satellite-denied environment, which is a critical concern for military planners.
- It details the technological advancements in HF, such as Wideband HF and 4th-Generation ALE, that make it a more viable and robust communication method.
- The report emphasizes the need for sufficient HF infrastructure to support combat operations at operational and strategic levels against peer adversaries.
Strategic Relevance
Maintaining assured Command and Control (C2) and battle space awareness in a satellite-denied environment is paramount for military operations against peer adversaries. This research directly addresses a critical vulnerability by proposing and evaluating the necessary High Frequency (HF) infrastructure, ensuring operational continuity and strategic resilience when primary satellite communications are compromised.
