The total length of the ship was 179 m, width 18.8 m, and her standard displacement - at the time of launching - about 10,200 tons. The maximum speed was up to 32.7 knots. The main armament at the time of the launch was 9 203 mm guns in three turrets of three guns each, and the secondary armament was mainly 8 127 mm guns.
USS Quincy (CA-39) was one of the New Orleans-class cruisers (originally: Astoria-class). These types of units were built to the tonnage limit imposed by the Washington Treaty, but marked a decisive step forward compared to the previous classes of American cruisers. First of all, the armor and the overall strength of the structure were significantly improved, which proved its great advantages during the fights in the Pacific. In addition, for the first time in the US Navy, 203 mm main artillery was used in real turrets. The maximum possible speed was also taken care of. Undoubtedly, ships of this class were very successful units, able to compete with their Japanese counterparts without any problems. USS Quincy (CA-39) from September 1939 patrolled the eastern coast of the USA and the Caribbean Sea. In the period June-September 1940, he made a cruise to the countries of South America. Despite the US's formal neutrality, from April 1941, it covered convoys sailing across the Atlantic from North America to the British Isles. In June 1942, the cruiser was sent to the Pacific, after prior renovation and modernization of the weapon configuration. In July 1942, it was already operating in the area of the island of Guadalcanal, and on August 9 of the same year, it was sunk during a night battle near the island of Savo.
