US Department of Defense (DoD) Birthday (The Museum is CLOSED)

August 10
|Recurring Event (See all)

An event every year that begins at 12:00 am on day 10 of August, repeating until August 10, 2030

The U.S. Department of Defense (DoD) was established August 10th, 1949. Although, the federal government has overseen the U.S. Armed forces since our nation’s inception, the Department of Defense name and centralized defense department was not established until the late 1940s. The “official” anniversary of the creation of the Department of Defense as we know it in modern times is August 10. Established in 1949 thanks to an amended National Security Act (more on that below) the agency is run by the Secretary of Defense (SECDEF) with the Joint Chiefs of Staff for the various military services operating subordinately to the SECDEF.

The DoD Birthday will be celebrated on Monday, August 10, 2020.

The United States Department of Defense (DoD) is a federal agency described as an Executive Branch department. The DoD is described as being among the largest employers in the world; there are more than one million active duty service members, more than 800 thousand members of the Guard and Reserve, and more than 700 thousand civilian employees.

The Department of Defense headquarters is located inside the Pentagon operating with the mission statement to provide the nation with military forces to act as a deterrent and provide national security.

The official date of the creation of the Department of Defense may be a bit misleading for some as the nation has always had an entity that operated in a similar capacity; but as we’ll learn below the road to the DoD as we now know it was a long and winding one.
