The size of a modern warship can vary significantly depending on its type and purpose. For instance, a destroyer might be around 500 to 600 feet long and displace approximately 6,000 to 10,000 tons, while aircraft carriers can exceed 1,000 feet in length and displace over 100,000 tons. Smaller vessels like frigates and corvettes are generally less than 500 feet long and displace between 1,000 to 5,000 tons. Overall, modern warships are designed with advanced technology and capabilities, impacting their size and structure.

They would have been called a "ship of the line".
A frigate can be any of several classes of "warship." Modern frigates are similar in size to destroyers, i.e. smaller than cruisers. US frigates are comparable to the Destroyer Escorts of World War II, which were more heavily armed ships.
