American seaborne forces during the Revolution consisted of armed ships from what?

American seaborne forces during the Revolution primarily consisted of armed ships from the Continental Navy and various state navies. These vessels were a mix of privateers and warships commissioned by individual states, as the Continental Congress initially lacked a centralized naval force. The privateers played a crucial role in disrupting British supply lines and capturing enemy ships, significantly contributing to the American war effort. Additionally, merchant vessels were often outfitted for combat, further expanding the naval presence.
