During the late 18th century, battleships were classified as what type of ship?

During the late 18th century, battleships were classified as ships of the line. This classification denotes a specific type of warship that was part of the naval tactics of the time, primarily designed to engage in battle line formations. Ships of the line were heavily armed and built to withstand the rigors of major naval engagements. They played a central role in naval warfare during this period, often participating in large fleet actions where multiple ships would engage the enemy in a line of battle.

The term "ships of the line" implies their intended role in direct confrontations with other navies, distinct from other naval vessels such as frigates or sloops of war, which had different operational roles, including reconnaissance, escort duties, or patrolling. Merchant ships, on the other hand, were primarily geared towards trade and cargo transport, lacking the heavy armament and armor of ships of the line. Thus, understanding this classification highlights the evolution of naval strategy and shipbuilding during a pivotal time in maritime history.
