If a natural emergency or disaster strikes the U.S., the 595th Command and Control Group is responsible for operating a plane called E-4B's.E-4B's are militarized Boeing 7-47's equipped to execute emergency war orders and coordinate responses.It is the first time since the E-4B realigned under Air Force Global Strike Command and 8th Air Force in 2016, that there has been a media flight on the aircraft. KETV NewsWatch 7 got the chance to go on board and see what is inside. Aircrews maintain America's four E-4B's. One is always ready to put the president in the sky if communication isn't immediately available.It's where senior officials would go if a nuclear attack or natural disaster knocks out communication across the US."So I want people to understand what we do. As a taxpayer's standpoint I want them to know what their money's doing. I want them to have confidence that our nation has the capabilities in a time of crisis," said Col. Brian Golden, national airborne operations center.For 60 years the national airborne operations center's "Night-watch" program has prepared these planes to send U.S. decision-makers up above. Three shifts rotate every eight hours, 24/7. "We train for it a lot. And so I feel confident. We'd be ready to go," said Benjamin Stickler, National Airborne Operations Center.This is deemed the "Doomsday plane" because this assembly line of communication kicks into gear during a national emergency. At least two watch officers are standing by 24/7 to receive alerts from across the country.It's a "survivable" command center that costs $147,000 to fly each hour when fully generated.Colonel Brian Golden says it's better to be bored on this plane because if it's time to work something somewhere destroyed ground command.Whether it's Mother Nature or an adversary. As war continues in Ukraine, N.A.O.C. said the U.S. does not face a direct nuclear threat from Russia."Since there's no threat to the continental United States, we aren't doing anything different than we do day-to-day. If there ever is a threat to the continental United States that's when we would be a little more concerned about that," said Col. Brian Golden.Every day these crew members think about the real-world implications this assembly line of communication means for the rest of us. They have been on watch for 60 years and counting.E-4B fact sheetPrimary function: Airborne operations centerBuilder: Boeing Aerospace Co.Power plant: Four General Electric CF6-50E2 turbofan enginesThrust: 52,500 pounds (each engine)Length: 231 feet, 4 inches (70.5 meters)Wingspan: 195 feet, 8 inches (59.7 meters)Height: 63 feet, 5 inches (19.3 meters) Maximum takeoff weight: 800,000 pounds (360,000 kilograms)Endurance: 12 hours (unrefueled)Ceiling: above 30,000 feet (9,091 meters) Unit cost: $223.2 million (fiscal 98 constant dollars)Crew: Up to 112Date deployed: January 1980Inventory: Active force, 4; Air National Guard, 0; Reserve, 0 Learn more about the E-4B here
