How many hours in advance does the military notify ARTCC of a flush/dispersal operation?

The military notifies the ARTCC (Air Route Traffic Control Center) of a flush/dispersal operation 1 hour in advance. This advance notice is crucial for ensuring that air traffic controllers can effectively manage air traffic and coordinate the safe movement of military aircraft within controlled airspace. Providing this notice allows for proper planning and deconfliction of airspace, thus enhancing overall safety and efficiency during military operations. The 1-hour timeframe allows the ARTCC to integrate this operation into the existing air traffic management system without significant disruption.
