Which type of ship is included among the first three classes of Navy ships established in 1775?

The classification of sloop of war as one of the first three classes of Navy ships established in 1775 highlights the historical context and operational needs of the fledgling United States Navy. Sloops of war were designed to be nimble, fast vessels capable of carrying armaments while still being relatively easy to maneuver. This made them suitable for a variety of missions, including patrolling, escorting, and engaging in combat.

During the early years of the U.S. Navy, sloop of war was integral to maritime operations, allowing the navy to assert its presence on the seas and protect American interests. The sloop's design and function reflected the strategic needs of a growing maritime nation during the Revolutionary War and beyond. In contrast, other types of vessels mentioned were either not pertinent to naval warfare at that time or were developed later, thus solidifying the unique position of the sloop of war in early naval history.
