In 2011 I saw a U.S. Navy Boeing 707 at North Island Naval Air Station 100th anniversary air show. That plane was the command center to direct the ballistic missile submarines after the U.S. has been attacked. The crew members were there answering questions. That 707 reminded me of the doomsday machine in Dr. Strangelove.
“Gentlemen, you can’t fight in here! This is the War Room!”
“Mr. President, I’m not saying we wouldn’t get our hair mussed, but I do say no more than ten to twenty million killed, tops, that is, depending on the breaks.”
The Boeing E-4 Advanced Airborne Command Post, with the project name "Nightwatch",[2] is a strategic command and control military aircraft operated by the United States Air Force (USAF). The E-4 series was specially modified from the Boeing 747-200B for the National Emergency Airborne Command Post (NEACP) program. The E-4 serves as a survivable mobile command post for the National Command Authority, namely the President of the United States, the Secretary of Defense, and successors. The four E-4Bs are operated by the 1st Airborne Command and Control Squadron of the 595th Command and Control Group located at Offutt Air Force Base, near Omaha, Nebraska. An E-4B when in action is denoted a "National Airborne Operations Center".
