Boeing E-6B Mercury
The Boeing E-6 Mercury (formerly E-6 Hermes) is an airborne command post and communications relay based on the Boeing 707-300. The original E-6A manufactured by Boeing's defense division entered service with the United States Navy in July 1989, replacing the EC-130Q. This platform, now modified to the E-6B standard, conveys instructions from the National Command Authority to fleet ballistic missile submarines (see communication with submarines), a mission known as TACAMO ("Take Charge And Move Out"). The E-6B model deployed in October 1998 has the ability to remotely control Minuteman ICBMs using the Airborne Launch Control System. The E-6B replaced Air Force EC-135Cs in the ''Looking Glass'' role, providing command and control of U.S. nuclear forces should ground-based control become inoperable. With production lasting until 1991, the E-6 was the final new derivative of the Boeing 707 to be built. Design and development Like the E-3 Sentry Airborne Warning and Control ...

Boeing EC-135
The Boeing EC-135 is a retired family of command and control aircraft derived from the Boeing C-135 Stratolifter. During the Cold War, the EC-135 was best known for being modified to perform the Operation Looking Glass, Looking Glass mission where one EC-135 was always airborne 24 hours a day to serve as flying command post for the Strategic Air Command in the event of nuclear war. Various other EC-135 aircraft sat on airborne and ground alert throughout the Cold War, with the last EC-135C being retired in 1998. The EC-135N variant served as the tracking aircraft for the Apollo program. The Boeing E-6 Mercury, Boeing E-6B Mercury "TACAMO" replaced the EC-135C. Missions Looking Glass Officially known as "Operation Looking Glass", at least 11 EC-135C command post aircraft were provided to the Commander in Chief, Strategic Air Command (CINCSAC), and were based at various locations throughout the United States and worldwide.

Looking Glass (airplane)
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.

Maiden Flight
The maiden flight, also known as first flight, of an aircraft is the first occasion on which it leaves the ground under its own power. The same term is also used for the first launch of rockets. In the early days of aviation it could be dangerous, because the exact handling characteristics of the aircraft were generally unknown. The maiden flight of a new type is almost invariably flown by a highly experienced test pilot. Maiden flights are usually accompanied by a chase plane, to verify items like altitude, airspeed, and general airworthiness. A maiden flight is only one stage in the development of an aircraft type. Unless the type is a pure research aircraft (such as the X-15), the aircraft must be tested extensively to ensure that it delivers the desired performance with an acceptable margin of safety. In the case of civilian aircraft, a new type must be certified by a governing agency (such as the Federal Aviation Administration in the United States) before it can enter ...

Boeing Renton Factory
The Boeing Renton Factory is the Boeing Company's manufacturing facility for narrow-body commercial airliners, and their military derivatives. Production includes the Boeing 737 MAX passenger airliner and the Boeing P-8 Poseidon military patrol aircraft. The factory covers of floor space. The factory lies adjacent to Renton Municipal Airport. Background The Boeing Renton Factory is built on land reclaimed by the lowering of the level of Lake Washington in 1916. At that time, it was purchased by industrialist Charles H. Burnett who intended to use it for coal storage and shipment. Those plans never came to be, and the semi-swampland was used as a hay farm. In 1936, Burnett's daughter Amy Louise Burnett Bond, transferred the land back to the state of Washington. Coincidentally, Burnett Bond was a close friend of Bertha Potter (wife of William E. Boeing), being both her godmother, and living with her family while she attended finishing school. At the start of World War II, t ...

Airborne Early Warning And Control
An airborne early warning and control (AEW&C) system is an airborne radar early warning system designed to detect aircraft, ships, vehicles, missiles and other incoming projectiles at long ranges, as well as performing command and control of the battlespace in aerial warfare, aerial engagements by informing and directing friendly fighter aircraft, fighter and attack aircraft. AEW&C units are also used to carry out aerial surveillance airborne ground surveillance, over ground and maritime surveillance, maritime targets, and frequently perform battle management command and control (BMC2). When used at altitude, the radar system on AEW&C aircraft allows the operators to detect, track and prioritize targets and identify friendly aircraft from hostile ones in real-time and from much farther away than ground-based radars. Like ground-based radars, AEW&C systems can be detected and targeted by opposing forces, but due to aircraft mobility and extended sensor range, they are much less vul ...
