Which link does the HFRG (High Frequency Radio Group) primarily support?

The High Frequency Radio Group (HFRG) primarily supports Link-11, which is a tactical data link used by military forces for exchanging information in a networked environment. Link-11 is designed to facilitate the exchange of tactical information such as situational awareness, air and missile defense, and fleet coordination among naval forces, especially under conditions where line-of-sight or satellite communications may be limited.

Link-11 operates over high-frequency (HF) radio waves, which allows for communication over long distances even in challenging environments. This capability is particularly important for naval operations, where ships may be operating far from land-based networks. The functional design of Link-11 includes features such as secure communication, frequency hopping, and automatic message handling, which enhance operational security and reliability.

In contrast, the other data links, such as Link-10, Link-12, and Link-14, serve different purposes or function using alternative technologies. Link-10 is primarily used in air-to-air combat and can carry more complex data types, while Link-12 focuses on interoperability with various platforms but typically does not support the same scale of operational messaging as Link-11. Link-14 is an improved point-to-point link that is usually limited in scope compared to Link
