How many original frigates did the US Navy have at its inception?

The United States Navy was established in 1775 during the American Revolutionary War. At its inception, the Navy commissioned six frigates. These frigates were designed to be fast, well-armed, and capable of both offensive and defensive operations. The six original frigates were critical in establishing the United States' maritime capabilities and protecting American interests at sea.

The significance of this answer lies not only in the number but also in the historical context of these ships, as they represented the beginnings of a national naval force that would evolve over time. The other options do not reflect the accurate count, as the Navy began with a specific number of frigates that were crucial to its early operations and mission.
