Lexington-class battlecruiserとは 意味・読み方・使い方

The Lexington-class battlecruisers were the only class of battlecruiser to ever be ordered by the United States Navy. Six—given names from battles in the American Revolutionary War or the original six frigates—were planned as part of the massive 1916 building program, but their construction was repeatedly postponed in favor of escort ships and anti-submarine vessels. During these delays, the class was redesigned several times; they were originally designed to mount ten 14"/50 caliber guns and eighteen 5"/51 caliber guns on a hull with a maximum speed of 35 knots, but by the time of the definitive design, these specifications had been altered to eight 16"/50 caliber guns and sixteen 6"/53 caliber guns, with a speed of 33.25 knots to improve hitting power and armor (the decrease in speed was mostly attributed to the additions of armor).
