U.S. Air Force officials are working to replace by 2019 aging command and control terminals that are part of the U.S. Air Force’s nuclear bomber mission. The new terminals will communicate with advanced satellite constellations and also will add capabilities not in current systems.
The Global Aircrew Strategic Network Terminal (Global ASNT—pronounced global assent) is a ground-based, three-increment program that provides persistent, survivable and redundant command and control (C2) communications to the U.S. Air Force strategic bomber fleet. The terminals also provide a C2 capability for the tankers and intelligence, surveillance and reconnaissance aircraft supporting the nuclear bomber mission. It is a part of the Minimum Essential Emergency Communications Network (MEECN) that passes messages from national command authorities—the president and senior leaders—to nuclear forces.
The program will provide 45 fixed communication terminals for sites such as wing command posts, along with 45 transportable terminals to support dispersed operations. The first increment of the program will provide advanced extremely high frequency (AEHF) communications compatible with the new AEHF satellite constellation and will replace legacy Military Strategic Tactical Relay (MILSTAR)-compatible terminals. The AEHF constellation will be the military’s primary satellite system for highly protected communications following the launch of the fourth and final satellite in 2017.
The new AEHF terminals are required because of projected end-of-life issues with the MILSTAR satellite constellation and looming obsolescence of the currently fielded terminals. “It replaces unsustainable legacy systems. Some of the systems it replaces are getting toward the end of their life cycle, and they’re difficult to maintain,” says Lt. Col. Kenneth Decker, USAF, Global ASNT program manager. “It’s like when your car gets to the point where it costs too much to maintain it.”
