The United States Air Force recently transferred command of it's Boeing E-4B Nightwatch aircraft from Air Combat Command to Global Strike Command.
The four E-4B National Airborne Operations Center aircraft will now be operated under the command of the Eighth Air Force's 595th Command and Control Group (they were previously part of the 55th Wing).
As before the aircraft will be flown by the 1st Airborne Command Control Squadron at Offut Air Force Base but the realignment to Global Strike Command aligns more closely to the Air Force's nuclear capability.
The 595th CACG is comprised of four squadrons: the 1st Airborne Command Control Squadron, which operates the aircraft; the 595th Strategic Communication Squadron, which provides real-time, secure, nuclear survivable missile warning and C3 capabilities; the 595th Aircraft Maintenance Squadron, responsible for sustainment and upkeep of the E-4B as well as the 625th Strategic Operations Squadron.
