Explanation

A dreadnought is a battleship equipped with large guns of the same caliber. A dreadnought comes in handy in a sea war. There are a lot of types of boats, such as sailboats and yachts, but this is a boat with an unfriendly mission: war. Sometimes spelled dreadnaught, this battleship was bigger and speedier than previous battleships. It also packed impressive firepower in the form of high-caliber guns. It was named after the HMS Dreadnought, which set sail in 1906. However, the word goes back to the late 17th century when it meant a fearless person (who dreaded naught — nothing).
