U.S. Strategic Command is conducting a nationwide nuclear readiness exercise involving strategic bombers, airborne communications aircraft and military personnel responsible for maintaining America’s nuclear deterrent during a crisis.
The exercise, known as Global Thunder 27, began Oct. 22 at Offutt Air Force Base in Nebraska. Military officials confirmed Tuesday that the operation was underway and warned that Americans could observe increased bomber and support aircraft activity during the training period.
According to an official announcement from U.S. European Command, the annual operation is designed to test nuclear command, control, communications and operational preparedness across the military’s strategic forces.
The exercise involves personnel from U.S. Strategic Command, its subordinate units and specialized task forces, with simulated scenarios testing military decision-making, logistical coordination and the ability to maintain communications during a major national security emergency.
Military officials emphasized that the operation is scheduled training rather than a response to an immediate international threat.
“This is an annual exercise and is not in response to actions by any nation, other actors or current world events,” the command said.
The training comes amid heightened international attention to nuclear weapons and military activity involving major powers, although officials have not linked Global Thunder 27 to any particular confrontation.
As the Daily Mail reported, flight-tracking information has shown increased activity involving B-52 strategic bombers and E-6B Mercury aircraft, commonly described as “doomsday planes” because of their role in maintaining emergency military communications.
The E-6B Mercury is an airborne command-and-control aircraft capable of relaying communications between national command authorities and U.S. nuclear forces.
Its responsibilities include maintaining communications with ballistic missile submarines and supporting nuclear command operations if ground-based communications systems become unavailable.
During a national emergency, such aircraft help preserve the ability of military leaders to communicate with strategic forces even if conventional communications infrastructure is damaged or disrupted.
Flight-tracking information cited in the report showed E-6B aircraft operating over several parts of the United States, including flights associated with Oklahoma.
B-52 bombers were also observed departing Minot Air Force Base in North Dakota, a major installation supporting America’s strategic nuclear capabilities.
Other military aircraft reported in flight-tracking data included a B-1B Lancer bomber operating over Texas.
Unlike the nuclear-capable B-52 and B-2 bombers, the B-1B is assigned exclusively to conventional weapons missions.
The presence of aircraft on public flight-tracking services does not independently establish their specific assignments, weapons configurations or direct participation in Global Thunder.
Military aviation notices have also identified temporary airspace reservations over portions of the Atlantic and Pacific oceans and areas near Florida.
One notice specifically referenced Global Thunder and established a reserved area over the Atlantic from Oct. 27 through Oct. 30.
Such restrictions allow military aircraft to conduct planned training while air traffic controllers separate those operations from civilian flights.
Global Thunder exercises are designed to test the coordination of the three components of America’s nuclear arsenal, collectively known as the nuclear triad.
The land-based component consists of intercontinental ballistic missiles deployed in hardened underground silos. The maritime component includes ballistic missile submarines armed with nuclear weapons, while the airborne component relies on long-range strategic bombers.
Maintaining reliable communications across those forces is a central responsibility of U.S. Strategic Command.
During a crisis, military leaders must be able to receive orders, verify their authenticity and transmit instructions to the appropriate units, even under conditions involving damaged infrastructure or disrupted communications.
Global Thunder allows participating personnel to rehearse those procedures through simulated emergencies without requiring an actual nuclear confrontation.
The military also evaluates operational planning, coordination among different service branches and the ability to sustain strategic missions over extended periods.
The exercise includes participation from international partners and allied forces.
According to UK Defence Journal, British and Norwegian F-35 fighter aircraft escorted an American B-52 bomber during Global Thunder training over the North Atlantic. A Royal Air Force Voyager tanker supported the formation.
The operation involved coordination with British and Norwegian naval forces operating in the region, demonstrating how allied aircraft can support American strategic aviation missions.
U.S. Strategic Command routinely conducts major readiness exercises to evaluate the nation’s ability to deter nuclear attacks and maintain command capabilities under difficult circumstances.
The previous Global Thunder exercise began in October 2025 and similarly involved increased bomber activity and personnel across the strategic forces network.
Officials describe the training as necessary to ensure that equipment, communications systems and military personnel remain prepared for unexpected emergencies.
Although some of the aircraft involved are capable of supporting nuclear operations, the exercise does not indicate that nuclear weapons have been deployed for use or that the United States has raised its nuclear alert status.
Global Thunder 27 is expected to continue into late October, with additional military flights and training activity possible throughout the exercise.
The operation represents one of the military’s major annual tests of strategic readiness, emphasizing the ability to maintain command of America’s nuclear forces and respond effectively during a national security crisis.
