Which ship remained as the last in the navy after the Revolutionary War?

The last ship in the navy after the Revolutionary War is the USS Alliance. This ship was part of the Continental Navy and played a significant role in that period. After the war, she was one of the few ships to remain in naval service as the United States began to shift its focus towards establishing a peacetime navy. The USS Alliance was utilized for various purposes, including acting as a merchant vessel and engaging in diplomatic missions. Her survival and continued use illustrate the challenges faced by the early United States as it sought to maintain a naval presence amidst limited resources and the shifting priorities following the war.

In contrast, USS Constitution, while famous and still in service today, was launched in 1797 and was not part of the immediate post-war fleet. USS Intrepid and USS Philadelphia also had notable histories, but they were retired or lost during the war. This makes USS Alliance the only correct answer regarding the ship that remained in service as the last one following the Revolutionary War.
