What is the name of the first Navy Flagship?

The first Navy flagship is known to be the USS Alfred, which served as a significant vessel in the early days of the United States Navy. Commissioned in 1775, she played a pivotal role in the American Revolutionary War by taking part in several crucial engagements and displaying the naval capabilities of the nascent United States.

The USS Alfred was notable for its advanced design for the era and served under Commodore Esek Hopkins, the first commander-in-chief of the Continental Navy. This vessel was integral in the establishment of U.S. naval power and helped to demonstrate the importance of a strong naval presence during the Revolutionary War.

While the USS Constitution, USS Enterprise, and USS Constellation are also famed ships with rich histories and notable contributions to naval history, they were not the first flagship of the Navy. The USS Constitution, also known as "Old Ironsides," became famous later in the early 19th century, while the other two were involved in different contexts and timelines that did not precede the Alfred's status as the initial flagship.
