For 20 years after her commissioning in 1920, "Hood" was the largest and heaviest warship in the world. Combining eight massive BL 15-inch Mk I naval guns with a top speed greater than any battleship on the sea, "Hood" was the pride of Great Britain's navy, and embodied the world dominance of British naval power. Despite this, "Hood" had one conspicuous flaw as compared to the super-dreadnought battleships she served alongside: as a battlecruiser, much of her bulk was dedicated to extra engine power instead of comprehensive armour coverage. This came from her design as a Admiral-class battlecruiser to meet the threat of the German Mackensen-class battlecruisers.
