The term "Dreadnought" primarily refers to a type of battleship that revolutionized naval warfare in the early 20th century. Launched by the British Royal Navy in 1906, the HMS Dreadnought featured an all-big-gun armament and steam turbine propulsion, making it faster and more powerful than its predecessors. This design rendered older battleships obsolete and led to a naval arms race among major powers. In a broader context, "Dreadnought" can also refer to a class of warships that followed the original design, as well as to various military and cultural references. The term has been used in literature, video games, and even in the naming of certain types of military vehicles, reflecting its lasting impact on popular culture and military history.
