noun
Historical naval term for a battleship larger and more powerful than a standard dreadnought, used in early 20th-century contexts.
第一次世界大戦前、各国は超弩級艦の建造を競った。
Before World War I, nations competed to build superdreadnoughts.
弩級艦 refers to a standard dreadnought battleship, while 超弩級艦 is a superdreadnought, a larger and more heavily armed evolution of the design.
Compound of 超 (super) + 弩級 (dreadnought-class) + 艦 (warship). 弩級 is a Japanese abbreviation of 'dreadnought', from the British battleship HMS Dreadnought.
