Which communication system is the backbone of the Navy's COMM system?

The backbone of the Navy's communication system is centered around the High-Speed Global Network (HSGR). This system serves a crucial role in connecting various Navy assets and facilitating high-capacity, high-speed voice, video, and data communications across the globe. By providing a robust infrastructure, HSGR supports the increasing need for reliable and secure communications in naval operations, ensuring that critical information can be shared efficiently among command and operational units.

While other systems like ISNS (Integrated Shipboard Network System), CENTRIXS (Combined Enterprise Regional Information Exchange System), and ADNS (Automatic Digital Network System) provide essential functions and support different communication aspects, they are often built on or integrated with the backbone provided by the HSGR. Their roles complement the high-speed, global connectivity that HSGR offers, but they do not stand as the main structural support for the Navy's overall communication framework.
