The total length of the ship was 179 m, width 18.8 m, and her standard displacement - at the time of launching - about 10,100 tons. The maximum speed was up to 32.7 knots.

USS Tuscaloosa (CA-37) 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 Tuscaloosa (CA-37) was in the Atlantic at the outbreak of World War II. Despite the Japanese attack on Pearl Harbor, the cruiser still remained in this area, serving primarily as a shielding ship for the Allied convoys. In November 1942, the USS Tuscaloosa supported the Allied landing in northwest Africa as part of Operation Torch. In June 1944, the cruiser took an active part in the Allied landing in Normandy. After Operation Overlord, the USS Tuscaloosa was briefly re-navigated to the Mediterranean Sea and later to the Pacific Ocean. There, in February 1945, she supported the American activities on Iwo-Jima. Later, it also supported the fighting of the US Marines in Okinawa. The USS Tuscaloosa was decommissioned in 1946 and sold for scrap in 1959.
