The President's Emergency Operations Center (PEOC) is a structure that lies beneath the East Wing of the White House in the United States. Originally constructed for PresidentFranklin D. Roosevelt during World War II, it is presumed to be designed to withstand all but direct nuclear blasts and is likely to be the President's evacuation point in the event of an incoming ICBM (the main protocols of escape are highly classified). It is not in the same location as the Situation Room, which is in the basement of the West Wing. However, it does possess several televisions, telephones and a communications system to coordinate with other government entities during an emergency. During a breach of White House security, to include P-56 airspace violators, the President and other protectees will be relocated to the executive briefing room, next to the PEOC. Day to day, the PEOC is manned around the clock by joint service military officers and NCOs.
