The E-4B "Nightwatch," often called the "Doomsday Plane," is one of the most advanced and expensive aircraft operated by the U.S. Air Force.
Designed to protect the President of the United States during catastrophic events, including a potential nuclear attack, it doubles as a mobile command and control center in the event of an apocalyptic scenario.
Unlike Air Force One, which serves primarily as a flying office for the President, the E-4B can operate as a full-scale military strategy hub.
With a construction cost of $223.2 million and operating costs of $159,529 per hour, it is the most expensive aircraft in the U.S. Air Force fleet, according to Ziare.
The E-4B is a militarized version of the Boeing 747-200. The fleet of four planes is based at Offutt Air Force Base in Nebraska, home to the National Airborne Operations Center.
The aircraft is equipped with advanced shielding against nuclear blasts and electromagnetic pulses, ensuring its systems remain operational in extreme conditions.
Accommodate 112 Passengers
It features extensive communications capabilities, including 67 satellite and other antennas housed in a specialized “radome.”
This setup allows the E-4B to maintain superior communication functions compared to Air Force One. The aircraft can refuel mid-air, enabling it to remain airborne for days at a time if necessary.
The E-4B's interior is divided into six functional zones, including a command center, briefing room, conference area, and rest quarters.
It can accommodate up to 112 passengers, including military officials, staff, and media personnel. The Secretary of Defense often uses the aircraft for international travel, with private quarters featuring a bed and office space.
On alert 24/7 since its introduction in 1975, at least one E-4B is always ready for deployment.
In the event of a nuclear attack or another national crisis, the President, Secretary of Defense, and the Chairman of the Joint Chiefs of Staff would use the E-4B as a secure, airborne Pentagon.
The E-4B "Nightwatch" is a testament to the U.S. military's readiness for worst-case scenarios, ensuring continuity of government and military command under any circumstances.
