How old is the US Navy?

  • The U.S. Navy traces its official birth to 13 October 1775 , when the Second Continental Congress voted in Philadelphia to fit out two armed vessels, creating the Continental Navy.
  • From 13 October 1775 to the current year 2026, the U.S. Navy is therefore 250 years old (it will mark its 250th birthday on October 13, 2025, and remain in its 250th year through most of 2026).

In short: when people ask “how old is the US Navy,” they’re usually referencing its founding on October 13, 1775, which makes it roughly 250 years old today.
