main battery of nine SK C/25 guns mounted in three triple gun turrets. One was located forward, and two were placed in a superfiring pair aft, all on the centerline. They were supplied with between 1,080 and 1,500 rounds of ammunition, for between 120 and 166 shells per gun. The ship was also equipped with eight SK C/32 anti-aircraft guns, eight SK C/30 anti-aircraft guns, and several anti-aircraft guns, though the number of the latter changed over her career. Nürnberg also carried four triple torpedo tube mounts located amidships; they were supplied with twenty-four torpedoes. She was also capable of carrying 120 naval mines. The ship was protected by an armored deck that was thick amidships and an armor belt that was thick. The conning tower had thick sides. Modifications After the outbreak of war, the ship was fitted with a degaussing coil to protect her against magnetic mines. In 1942, the ship's aircraft handling equipment and aft torpedo tubes were removed. Throughout the war, her radar suite was upgraded; in March 1941, she was equipped with FuMO 21 radar and in early 1942, a FuMO 25 radar set was installed. The latter was a search radar for surface targets and low-flying aircraft at low range. The FuMO 21 set was replaced by the short-range FuMO 63 Hohentwiel 50-centimeter radar. Nürnberg was also fitted with four Metox radar warning receivers. The ship's anti-aircraft battery was improved over the course of World War II. In late 1942, a pair of Army-variant 2 cm Flakvierling quadruple mounts were installed, one on the navigating bridge and the other on top of the aft superfiring turret. In May 1944, the navy proposed installing several Bofors 40 mm guns, but most of these weapons were diverted to other uses, and only two guns were installed. One was mounted on the bridge and the other where the catapult had been located. Two Navy-pattern Flakvierlings were added; one replaced the Army model atop the aft superfiring turret, and the other was placed in front of the anti-aircraft fire director. The Army-pattern Flakvierlings were moved to the main deck. In December 1944, another revised anti-aircraft plan was proposed, this time incorporating the new 3.7 cm FlaK 43 gun, of which there were to be eight, along with two Flakvierlings and ten 2 cm twin mounts. Germany's wartime situation by the end of 1944 prevented these changes from being
