Armed Forces Day Historical Timeline

July 26, 1947 – President Harry S. Truman signed the National Security Act into law (*Statute Compilation, codified in Title 50 of the U.S. Code: War and National Defense). This Act unified the four branches of the military under a single executive authority, the Secretary of Defense. This decision led to the creation of the National Military Establishment.

August 31, 1949 – Secretary of Defense Louis Johnson announced Armed Forces Day as a unification of the separate Army, Navy, Marine Corps, and Air Force celebrations, a reflection of the unification of the forces under the National Security Act. Armed Forces Day was intended to replace the separate days of celebration, but some branches maintain their own celebration in addition to the joint observance. (Source: Defense.gov ) Read remarks from Senator Lodge on Secretary Johnson's announcement as printed in the Congressional Record on April 7, 1949.

February 27, 1950 – The first Armed Forces day was proclaimed by Presidential Proclamation 2873, but not observed until May that year. President Truman declared, "Armed Forces Day, Saturday, May 20, 1950, marks the first combined demonstration by America's defense team of its progress, under the National Security Act, towards the goal of readiness for any eventuality. It is the first formal procession of preparedness by the unified forces of our land, sea, and air defense."

May 20, 1950 – Armed Forces Day is first celebrated.
