After 8:46 a.m. September 11, 2001: Navy Officials Monitor Events at Antiterrorist Alert Center

Within moments of the attack in New York, the US Navy’s Antiterrorist Alert Center (ATAC) goes to full alert. ATAC is located at the Naval Criminal Investigative Service (NCIS) headquarters in southeast Washington, DC, across the Potomac River from the Pentagon. [US Department of the Navy, 2/2002 ; CNN, 8/27/2002; US Naval Criminal Investigative Service, 8/22/2006] Established in 1983, it was the first 24-hour terrorism watch center in the US intelligence community. [US Naval Criminal Investigative Service, n.d.] In it, top Navy officials are now monitoring the day’s events. According to CNN—which gains access to a video recording of the center during the attacks—just before the Pentagon is hit, these officials are “concerned attacks on Washington could be next.” After the attack on the Pentagon, the Navy’s top leaders will start arriving at the center (see After 9:37 a.m. September 11, 2001).
