Excerpt: The North Carolina class was a group of two fast battleships, North Carolina and Washington, built for the United States Navy in the late 1930s and early 1940s. The navy was originally uncertain whether the ships should be fast enough to counter the Japanese Kong class, which was believed by the United States to be capable of 26 knots (30 mph; 48 km/h), or should sacrifice speed for additional firepower and armor. The Second London Naval Treaty's requirement that all capital ships have a standard displacement of under 35,000 long tons (35,560 metric tons) meant that the desired objectives could not be fully realized within the treaty limits, and the navy considered over fifty designs before one was chosen. Towards the end of this lengthy design period, the General Board of the United States Navy declared that it was in favor of design "XVI-C," which called for a speed of 30 knots (35 mph; 56 km/h) and a main battery of nine 14-inch (356 mm)/50 caliber Mark B guns. The board believed that such ships could fulfill a multitude of roles, as they would have enough protection to be put into a battle line while also having enough speed to escort aircraft carriers or engage in commerce raiding. However, the acting Secretary of the Navy authorized a modified version of a different design, "XVI," which in its original form had been rejected by the General Board. This called for a 27-knot (31 mph; 50 km/h) ship with twelve 14-inch rifles in quadruple turrets and protection against guns of the same caliber. In a major departure from traditional American design practices, "XVI" accepted lower speed and protection in exchange for maximum firepower. After construction had begun, the United States became concerned over Japan's refusal to commit to the..."
