E-4 NAOC

E-4

Description:


The E-4B serves as the National Airborne Operations Center for the president, secretary of defense and the Joint Chiefs of Staff or JCS.  In case of national emergency or destruction of ground command control centers, the aircraft provides a highly survivable, command, control and communications center to direct U.S. forces, execute emergency war orders and coordinate actions by civil authorities.

Features
Air Combat Command is the Air Force single-resource manager for the E-4B, and provides aircrew, maintenance, security and communications support. E-4B operations are directed by the JCS and executed through U.S. Strategic Command. USSTRATCOM also provides personnel for the airborne operations center.

The E-4B, a militarized version of the Boeing 747-200, is a four-engine, swept-wing, long-range, high-altitude airplane capable of being refueled in flight. Its larger size provides approximately triple the floor space of the earlier EC-135 command post.

The main deck is divided into six functional areas: a command work area, conference room, briefing room, an operations team work area, and communications and rest areas. An E-4B crew may include up to 112 people, including a joint-service operations team, an ACC flight crew, a maintenance and security component, a communications team and selected augmentees. 

The E-4B has electromagnetic pulse protection, an electrical system designed to support advanced electronics and a wide variety of new communications equipment. Other improvements include nuclear and thermal effects shielding, acoustic control, an improved technical control facility and an upgraded air-conditioning system for cooling electrical components. An advanced satellite communications system improves worldwide communications among strategic and tactical satellite systems and the airborne operations center. 

To provide direct support to the president, secretary of defense and the JCS, at least one E-4B is always on alert at one of many selected bases throughout the world. 

Background

The E-4B evolved from the E-4A, which had been in service since late 1974. The first B model was delivered to the Air Force in January 1980, and by 1985 all aircraft were converted to B models. All E-4B are assigned to the 55th Wing, Offutt Air Force Base, Neb.
