Which U.S. military branch celebrated its own 250th anniversary on June 14, 2025, ahead of America250?

The United States Army celebrated its own 250th anniversary on June 14, 2025, ahead of America250.

The Army traces its official establishment to June 14, 1775, when the Second Continental Congress created the Continental Army during the American Revolutionary War. That date is also observed annually as the Army's birthday and coincides with Flag Day in the United States.

A large 250th-anniversary parade and celebration took place in the Washington, D.C., area in 2025. The event included soldiers, military vehicles, aircraft, horses, bands, and other participants, and was described as an early or “soft launch” of broader anniversary activities.

The Army anniversary is separate from the nation's 250th anniversary in 2026. The Army was established one year before the Declaration of Independence was adopted. The Navy, Marine Corps, Air Force, Space Force, and Coast Guard have different founding dates and therefore do not share June 14 as their 250th anniversary.
