What is Operation Noble Eagle primarily focused on?

Operation Noble Eagle is primarily focused on protecting U.S. airspace. Following the September 11, 2001 attacks, this operation was initiated to enhance the security of the nation’s air defense system and ensure the safety of American skies from any potential terrorist threats. This has involved the deployment of military units, including aircraft and ground personnel, to monitor and secure airspace over still-active or vulnerable areas.

The emphasis on airspace protection highlights the operation's role in domestic security, contrasting it with efforts oriented towards overseas combat missions, humanitarian aid, or basic training activities, which do not primarily address the immediate concern of securing the airspace within U.S. borders.
