National Security Operations Center

The United States' National SIGINT Operations Center (NSOC) is the focal point for the National Security Agency's current operations center and focal point for time-sensitive SIGINT reporting for the United States SIGINT System (USSS).

History
In 1969, a U.S. Navy EC-121 patrol plane was shot down over the Sea of Japan. In the ensuing hours, NSA leaders raced from office to office to gather the information necessary to assemble a coordinated response for the Agency and National leadership. This incident demonstrated the need for a dedicated watch center to respond to breaking world events. Hence, NSOC has been established in 1972.

After the September 11 attacks, NSOC's mission was broadened from watch center to the operations center it is today.
