Operation Looking Glass

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). 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) 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.

The code name "Looking Glass" came from the aircraft's ability to "mirror" the command and control functions of the underground command post at the U.S. Air Force's Strategic Air Command (SAC) headquarters at Offutt AFB, Nebraska.

The SAC Airborne Command Post or "Looking Glass" was initiated in 1960, with the conversion of 5 KC-135A tankers to Airborne Command Posts. On July 1, 1960 operational testing began under the code name Looking Glass, with a SAC general officer always aboard each flight, and operated by the 34th Air Refueling Squadron at Offutt AFB. The mission transferred to the 38th Strategic Reconnaissance Squadron in August 1966, to the 2nd Airborne Command and Control Squadron in April 1970, to the 7th Airborne Command and Control Squadron in July 1994, and to the USSTRATCOM's Strategic Communications Wing One in October 1998.

The Strategic Air Command put Looking Glass mission on continuous airborne alert starting February 3, 1961, aircraft from the 34th Air Refueling Squadron based at its headquarters at Offutt AFB, backed up by aircraft flying with the Second Air Force / 913th Air Refueling Squadron at Barksdale AFB, Louisiana, Eighth Air Force / 99th Air Refueling Squadron at Westover AFB, Massachusetts, and Fifteenth Air Force / 22d Air Refueling Squadron, March AFB, California.

EC-135 Looking Glass aircraft were airborne 24 hours a day for over 29 years, until July 24, 1990, when "The Glass" ceased continuous airborne alert, but remained on ground or airborne alert 24 hours a day.

Looking Glass mirrors ground-based command, control, and communications (C3 or C³) located at the USSTRATCOM Global Operations Center (GOC) at Offutt AFB. 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.

The Looking Glass was also designed to help ensure continuity and reconstitution of the US government in the event of a nuclear attack on North America. Although the two types of aircraft are distinct, the Doomsday Plane nickname is also frequently associated with the Boeing E-4 "Nightwatch" Advanced Airborne Command Post mission and aircraft.

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:
