plural of dreadnought

(nautical, military, historical) A late 19th-century or early 20th-century battleship with a small number of big guns (typically no more than four) and a large number of quick-firing medium-caliber guns. It was made largely obsolete in 1906 by the dreadnought type of battleship.

plural of pre-dreadnought

A type of advanced pre-dreadnought battleship from the very early 20th century, carrying a main armament composed entirely of big guns of different calibers (typically having four guns of the largest caliber, plus a larger number of smaller big guns). It was superior to earlier pre-dreadnoughts, but still not as powerful as the dreadnought introduced in 1906.

plural of semi-dreadnought

plural of super-dreadnought

Alternative form of superdreadnought
