Trump’s ‘Doomsday Plane’ spotted circling U.S. nuclear war command center as Iran rejects ceasefire | 6 April 2026 | President Donald Trump’s emergency command aircraft is currently circling above a U.S. base home to America’s nuclear command center. The Boeing E-4B “Nightwatch,” also known as the “Doomsday plane,” made several loops above the Offutt Air Force Base in Nebraska on Monday. The massive jet serves as a flying command post for top officials, including the president, vice president and Secretary of War, during crises. It is a heavily modified Boeing 747 designed to survive nuclear blasts, electromagnetic pulses (EMP) and other worst-case scenarios. Flight tracking data shows the E-4B leaving Offutt at 10.17am ET, making at least six circles above and soaring off over Strahan, which is about 40 miles east.
