GWEN Ground Wave Emergency Network Emergency Communications
The Ground Wave Emergency Network ( GWEN) was a US Air Force command and control communications system, deployed briefly between 1992 and 1994, intended for use by the United States government to facilitate military communications before, during and after a nuclear war.

The Ground Wave Emergency Network (GWEN) is a communication system under development by the Air Force for which a Final Environmental Impact Statement was issued in September 1987.
GWEN Ground Wave Emergency Network Emergency Communications
The Ground-Wave Emergency Network (GWEN) is a communications system that the military is in the process of constructing as we speak. It operates in the very-low-frequency (VLF) range, with transmissions between 150 and 175 kHz.
GWEN Ground Wave Emergency Network Emergency Communications
The Ground Wave Emergency Network (GWEN) provides survivable connectivity to designated bomber and tanker bases. The system is in sustainment. GWEN is designed as an ultra-high powered VLF [150-175 kHz] network intended to survive massive broadband destructive interference produced by nuclear EMP, and recovering quickly from the changes imposed.

The Ground Wave Emergency Network (GWEN) is a communication system under development by the Air Force for which a Final Environmental Impact Statement was issued in September 1987. In 1990, members of Congress asked the Air Force to evaluate recent evidence that exposure to electromagnetic fields results in adverse biological effects and to.

GWEN is the Ground Wave Emergency Network, commissioned as AN/URC-117. It was part of the early Minimum Essential Emergency Communications Network (MEECN). The primary purpose of GWEN was to relay messages between SAC sites, including emergency action messages. The LF range used by GWEN, at around 150kHz, could propagate over long distances via.

GWEN Ground Wave Emergency Network Although GWEN was designed to provide survivable connectivity for time-critical force survival actions, the configuration does not meet required availability or reliability.
GWEN Ground Wave Emergency Network Ωmnibus
GWEN (Ground Wave Emergency Network) transmitters, placed 200 miles apart across the USA, allow specific frequencies to be tailored to the geomagnetic-field strength in each area, allowing the magnetic field to be altered. They operate in the VLF range, with transmissions between VLF 150 and 175 KHz. They also emit UHF waves of 225 - 400 MHz.
