Boeing E-6
"Codenamed Looking Glass, it is United States Strategic Command (USSTRATCOM)'s Airborne Command Post (ABNCP), designed to take over in case the Global Operations Center (GOC), located at Offutt Air Force Base, Nebraska, is destroyed or incapable of communicating with strategic forces. The term "Looking Glass" is used because the ABNCP "mirrors" the abilities of the US Strategic Command GOC to control nuclear forces"
