Part 4/9:
In the lead-up to World War II, naval engineers recognized the opportunity to enhance gunnery accuracy through improved ship stability measurements. The design and installation of the Mark 41 allowed for these improvements, which ultimately led to a significant redesign of battleships. With the introduction of this gyroscopic element, the United States was able to eliminate one of the masts entirely from its battleships, thus increasing the operational capability for anti-aircraft armaments.
