When is the anniversary of the Navy's establishment?

The anniversary of the Navy's establishment is recognized on October 13, 1775. This date marks the formation of the Continental Navy, which was established in response to the need for a naval force to protect American shipping and commerce from British ships during the American Revolutionary War.

The choice of this specific date is significant as it highlights the beginning of what would later evolve into the United States Navy, a crucial component of national defense and maritime operations. October 13 is celebrated each year as the Navy's birthday, commemorating its long history and traditions.

Other dates listed are noteworthy in their own right, such as July 4, 1776, which marks the Declaration of Independence, and November 10, 1775, the founding of the U.S. Marine Corps. However, only October 13, 1775, directly corresponds to the establishment of the Navy. September 11, 2001, is marked as a day of remembrance for the tragic events of that day and does not relate to the Navy's establishment.
