Recent flight tracking data reveals that the U.S. Navy's E-6B 'Mercury' strategic airborne command aircraft have been active in the skies. According to Jin10, these aircraft, often referred to as 'Doomsday Planes,' are designed to survive and coordinate U.S. military operations in a nuclear warfare environment. On March 2, two E-6B planes were observed over the United States: one took off from the Gulf Coast and landed at the Patuxent River Naval Air Station in Maryland, while the other departed from Offutt Air Force Base in Nebraska and returned there. Subsequently, additional E-6B aircraft reportedly crossed the Atlantic towards Europe. The Pentagon has declined to comment on these activities, citing 'operational security.'
