Which of the following types of ships were among the first in the Navy in 1775?

The types of ships that were among the first in the Navy in 1775 included frigates, line ships, and sloops of war. During this time, these vessel types played crucial roles in naval warfare and operations.

Frigates, known for their speed and maneuverability, were often used for escort missions and patrolling, allowing for greater flexibility in naval engagements. Line ships, representing the more powerful ships of the time, were designed to engage in set-piece battles in a line of battle formation, emphasizing firepower and tactics. Sloops of war, smaller and more agile than line ships, served a variety of purposes including scouting, anti-piracy missions, and supporting larger fleets.

Understanding the historical context of these ship types highlights their importance during the Revolutionary War and the establishment of the United States Navy. The other options listed, such as aircraft carriers and submarines, were not present in the 18th century, as these technologies and vessel types emerged much later in naval history. Therefore, the answer accurately reflects the vessels that were operational and critical during the early days of the Navy.
