Ballistics
Armor Model
Overview
CL-154 class cruisers were designed in the U.S. as a development of the Atlanta-class cruisers. They featured a larger hull and 5-inch guns. The new gun had a higher rate of fire, longer firing range, and heavier shells. Six ships even received their hull numbers, but construction was canceled due to cuts in the naval budget in 1945. Had they been completed, some of the cruisers might have been transferred to the Republic of Korea Navy, which in the 1950s and 60s acquired 42 warships of various types from the United States.
