HICOM
Because the requirements for rapid communications from the Department of the Navy to the fleet operational commanders had changed, the CNO authorized the activation of an additional teletypewriter system. This system, known as HICOM, was activated in 1957 and operated parallel to the existing communications channels.
Later, the Commander in Chief, U.S. Pacific Fleet (CINCPACFLT), established an additional parallel circuit known as the "Atomic Strike Coordinator Circuit." It was determined that even more rapid communications would be necessary. Therefore, a new communications net, known as the "Naval Operation Net" was formed in 1959.
from NCTAMS EASTPAC history
The HICOM network provides a voice link between the Chief of Naval Operations (CNO) and all subordinate commands ashore, afloat, and airborne. CNO is the master control station and each fleet commander in chief has an area network control station. All naval communications stations are members.
In cases where a fleet unit is suffering communications difficulties with normal channels, HICOM is used on a not-to-interfere basis to restore communications. All naval communications stations are required to guard HICOM for their respective area networks and use this system
