In what month and year did the Continental Congress establish the U.S. Navy?

The U.S. Navy was established by the Continental Congress in October 1775. This action was part of the Continental Congress's efforts to support the colonies' military operations against British forces during the American Revolution. The decision to create a naval force was driven by the need to address issues such as maintaining supply lines and engaging the British at sea.

In October 1775, the Congress authorized the building of two ships to help establish a naval presence. This foundational decision marked the beginning of what would evolve into the United States Navy, distinguishing it as a formal military branch dedicated to maritime operations.

Other months listed do not correspond to the actual date of establishment. For example, January 1775 predates the significant military engagements and preparations that led to the formation of the Navy. Similarly, August 1776 and July 1776 were later dates when the war had already escalated, but the Navy was already in existence by that time.
