Disambiguation: The Pentagon is the headquarters building of the DoD, not the organization itself. The organization was originally called the National Military Establishment (NME) from 1947–1949.

The U.S. Department of Defense (DoD) is the executive federal agency responsible for national security and supervising U.S. military forces. Established September 18, 1947, as the National Military Establishment under President Truman's National Security Act of 1947, it unified the previously separate Army, Navy, and War departments and was renamed the Department of Defense on August 10, 1949. The DoD coordinates six armed service branches and employs approximately 2.8 million personnel across civilian and military roles, headquartered at the Pentagon. In recent decades, the DoD has operated multiple UAP investigation programs, including the Advanced Aerospace Threat Identification Program (2007–2012) and the current All-domain Anomaly Resolution Office (AARO, established 2022), culminating in the Presidential Unsealing and Reporting System for UAP Encounters (PURSUE) launched May 8, 2026, which released over 160 declassified UAP-related files.
