Between 10:10 a.m. and 10:35 a.m. September 11, 2001: US Military’s Force Protection Level Is Raised

US military installations are placed on the highest state of alert, known as Force Protection Condition Delta (FPCON Delta), in response to the terrorist attacks in New York and at the Pentagon. The raised threat level applies to every US military installation across the country and around the world, and every member of the US armed forces. [Associated Press, 9/11/2001; US Department of Defense, 9/11/2001; New York Times, 9/12/2001] Measures that are taken once FPCON Delta has been declared include placing more guards on duty at military installations, having all vehicles on installations identified, and having all personnel positively identified. Additionally, all suitcases, briefcases, and packages brought into an installation must be searched. [Slate, 9/12/2001]
Rumsfeld and Myers Decide to Raise the FPCON – The decision to raise the force protection condition is apparently made by Secretary of Defense Donald Rumsfeld and/or acting Chairman of the Joint Chiefs of Staff Richard Myers. Rumsfeld will tell the 9/11 Commission that after he arrives at the Pentagon’s National Military Command Center (NMCC) (see (10:30 a.m.) September 11, 2001), he and Myers “discussed, and I recommended… increasing the force protection level.” [9/11 Commission, 3/23/2004 ] Myers will later write that after he arrives at the NMCC (see (9:58 a.m.) September 11, 2001), he “recommended that all American military commands and units worldwide go to [FPCON] Delta.” He will add: “Terrorists had staged major attacks in New York and Washington. Although we did not yet have reliable intelligence on when and where they would strike next, it seemed likely that they would.” [Myers and McConnell, 2009, pp. 153] But White House counterterrorism chief Richard Clarke will write that he gave the instruction to raise the force protection condition, at around 9:30 a.m. (see (9:29 a.m.) September 11, 2001). [Clarke, 2004, pp. 5-6]
Conflicting Times Are Given for the Raising of the FPCON – The exact time at which the force protection condition is raised is unclear. CNN’s Barbara Starr will report that “all US military forces [are] ordered to Condition Delta” at 10:10 a.m. [CNN, 9/4/2002] However, other evidence indicates the force protection condition is raised at a later time, around 10:35 a.m. Rumsfeld only enters the NMCC at about 10:30 a.m., indicating it is raised after that time. [9/11 Commission, 7/24/2004, pp. 43-44] And at 10:38 a.m., after Vice President Dick Cheney asks him on the air threat conference call if US forces are on “heightened alert,” Rumsfeld will reply, “Yes,” and say they are at FPCON Delta. [US Department of Defense, 9/11/2001 ]
Some Areas Are Already at FPCON Delta – Although the entire US military is now under the same FPCON level, usually, different locations can have different FPCON levels. [Slate, 9/12/2001] US forces in some parts of the world, particularly the Middle East and the Persian Gulf region, are in fact already at FPCON Delta. [New York Times, 9/12/2001] (The force protection condition was raised in those areas in late June, after intelligence reports suggested that terrorists might attack American military or civilian targets in the region (see June 21, 2001). [Los Angeles Times, 6/23/2001; National Public Radio, 5/23/2002; 9/11 Commission, 7/24/2004, pp. 257] ) Shortly after the force protection condition is raised, Rumsfeld will order that the defense readiness condition also be raised (see (10:43 a.m.-10:52 a.m.) September 11, 2001). [US Department of Defense, 9/11/2001 ; 9/11 Commission, 7/24/2004, pp. 326, 554]
There Are Five Possible Force Protection Conditions – The force protection condition is a “chairman of the Joint Chiefs of Staff-approved standard for identification of, and recommended responses to, terrorist threats against US personnel and facilities,” according to the Department of Defense. [US Department of Defense, 11/8/2010 ] It was created in June 2001 and replaced the “terrorist threat condition,” or “Threatcon.” [Los Angeles Times, 1/22/2002] There are five possible force protection conditions. The lowest, FPCON Normal, means no threat of terrorist activity is present. The other conditions are Alpha, Bravo, Charlie, up to the highest, FPCON Delta, which means a terrorist attack has occurred or intelligence has been received indicating that action against a specific location is likely.
