Looking Glass (or Operation Looking Glass) is the historic code name for an airborne command and control center operated by the United States. In more recent years it has been more officially referred to as the ABNCP (Airborne National Command Post).[1] It provides command and control of U.S. nuclear forces in the event that ground-based command centers have been destroyed or otherwise rendered inoperable. In such an event, the general officer aboard the Looking Glass serves as the Airborne Emergency Action Officer (AEAO)[2] and by law assumes the authority of the National Command Authority and could command execution of nuclear attacks. The AEAO is supported by a battle staff of approximately 20 people, with another dozen responsible for the operation of the aircraft systems. The name Looking Glass, which is another name for a mirror, was chosen for the Airborne Command Post because the mission operates in parallel with the underground command post at Offutt Air Force Base.[3]
EC-135 Looking Glass aircraft were airborne 24 hours a day for over 29 years,[9] until July 24, 1990,[10] when "The Glass" ceased continuous airborne alert, but remained on ground or airborne alert 24 hours a day.[11]
Looking Glass mirrors ground-based command, control, and communications (C3 or C³) located at the USSTRATCOM Global Operations Center (GOC) at Offutt AFB.[6] The EC-135 Looking Glass aircraft were equipped with the Airborne Launch Control System, capable of transmitting launch commands to U.S. ground-based intercontinental ballistic missiles (ICBMs) in the event that the ground launch control centers were rendered inoperable.[6][12][13]
The Looking Glass was the anchor in what was known as the World Wide Airborne Command Post (WWABNCP) network. This network of specially equipped EC-135 aircraft would launch from ground alert status and establish air-to-air wireless network connections in the event of a U.S. national emergency. Members of the WWABNCP network included:
Operation "Scope Light" for the Commander in Chief, U.S. Atlantic Command (CINCLANT), based at Langley AFB, VA;
Operation "Blue Eagle" for the Commander in Chief, U.S. Pacific Command (USCINCPAC), based at Hickam AFB, HI; and
Operation "Nightwatch" which supported the President of the United States and were based at Andrews AFB, Maryland. In the early 1970s the E-4A aircraft replaced the EC-135Js on this mission.[7]
The Eastern Auxiliary (EAST Aux) and Western Auxiliary (West Aux) Command Posts were also part of the WWABNCP ("wah-bin-cop") network and were capable of assuming responsibility for Looking Glass as the anchor. The West Aux 906th Air Refueling Squadron was based at Minot AFB, North Dakota, and moved to the 4th Airborne Command and Control Squadron at Ellsworth AFB, South Dakota, in April 1970 and the East Aux mission 301st Air Refueling Squadron was based at Lockbourne AFB, Ohio, and moved to the 3rd Airborne Command & Control Squadron at Grissom AFB, Indiana, in April 1970. After 1975, East Aux was assumed from the Looking Glass backup ground alert aircraft launched from Offutt AFB. In June 1992, United States Strategic Command took over the Looking Glass mission from the Strategic Air Command, as SAC was disbanded and Strategic Command assumed the nuclear deterrence mission.[7]
Current status
On October 1, 1998, the United States Navy fleet of E-6Bs replaced the EC-135C in performing the "Looking Glass" mission, previously carried out for 37 years by the U.S. Air Force. Unlike the original Looking Glass aircraft, the E-6Bs are modified Boeing 707 aircraft, not the military-only KC-135. The E-6B provides the National Command Authority with the same capability as the EC-135 fleet to control the nation's intercontinental ballistic missile (ICBM) force, nuclear-capable bombers and submarine-launched ballistic missiles (SLBM).[6] With the assumption of this mission, a USSTRATCOM battle staff now flies with the TACAMO crew.[14][6]
If the USSTRATCOM Global Operations Center (GOC) is unable to function in its role, the E-6B Looking Glass can assume command of all U.S. nuclear-capable forces. Flying aboard each ABNCP is a crew of 22, which includes an air crew, a Communications Systems Officer and team, an Airborne Emergency Action Officer (an Admiral or General officer), a Mission Commander, a Strike Advisor, an Airborne Launch Control System/Intelligence Officer, a Meteorological Effects Officer, a Logistics Officer, a Force Status Controller, and an Emergency Actions NCO. In addition to being able to direct the launch of ICBMs using the Airborne Launch Control System, the E-6B can communicate Emergency Action Messages (EAM) to nuclear submarines running at depth by extending a two and a half-mile-long (4 km) trailing wire antenna (TWA) for use with the Survivable Low Frequency Communications System (SLFCS), as the EC-135C could.[6]
There was some speculation that the "mystery plane" seen flying over the White House on September 11, 2001, was some newer incarnation of Looking Glass. However, the plane circling the White House on 9/11 was a E-4B (callsign ADDIS77/VENUS77) acting as the tertiary NAOC (Nightwatch) aircraft which was launched from ground alert at Andrews Air Force Base.[15]
