context_page_description: SMS Regensburg was a light cruiser of the Graudenz class built by the German Kaiserliche Marine. She had one sister ship, SMS Graudenz. The ship was built by the AG Weser shipyard in Bremen, laid down in 1912, launched in April 1914, and commissioned into the High Seas Fleet in January 1915. She was named for the German town of Regensburg. The ship was armed with a main battery of twelve 10.5 cm SK L/45 guns and had a top speed of 27.5 knots, though in 1917 she was rearmed with seven 15 cm SK L/45 guns.
  Regensburg served in the reconnaissance forces of the High Seas Fleet during World War I. She saw significant action at the Battle of Jutland on 31 May – 1 June 1916, where she served as the leader of the torpedo boat flotillas that screened for the I Scouting Group battlecruisers. After the end of the war, she was ceded to France in 1920 and renamed Strasbourg. In 1928 she took part in the Arctic rescue operations searching for the Airship Italia. Removed from service in 1936, she was used as a barracks ship in Lorient until 1944, when she was seized by the Germans and scuttled in the harbor to protect the U-boat pens there.
context_section_description: Regensburg was 142.7 meters (468 ft) long overall and had a beam of 13.8 m (45 ft) and a draft of 5.75 m (18.9 ft) forward. She displaced 6,382 t (6,281 long tons) at full load. Her propulsion system consisted of two sets of Marine steam turbines driving two 3.5-meter (11 ft) propellers. They were designed to give 26,000 shaft horsepower (19,000 kW). These were powered by ten coal-fired Marine-type water-tube boilers and two oil-fired double-ended boilers. These gave the ship a top speed of 27.5 knots (50.9 km/h; 31.6 mph). Regensburg carried 1,280 t (1,260 long tons) of coal, and an additional 375 t (369 long tons) of oil that gave her a range of approximately 5,500 nautical miles (10,200 km; 6,300 mi) at 12 knots (22 km/h; 14 mph). She had a crew of 21 officers and 364 enlisted men.
  The ship was armed with twelve 10.5 cm (4.1 in) SK L/45 guns in single pedestal mounts. Two were placed side by side forward on the forecastle, eight were located amidships, four on either side, and two in a superfiring pair aft. The guns had a maximum elevation of 30 degrees, which allowed them to engage targets out to 12,700 m (41,700 ft). These were later replaced with seven 15 cm (5.9 in) SK L/45 guns and two 8.8 cm (3.5 in) SK L/45 anti-aircraft guns. She was also equipped with a pair of 50 cm (19.7 in) torpedo tubes with five torpedoes submerged in the hull on the broadside. Four deck-mounted launchers were added when the gun armament was upgraded, and the submerged tubes were removed. She could also carry 120 mines. The ship was protected by a waterline armored belt that was 60 mm (2.4 in) thick amidships. The conning tower had 100 mm (3.9 in) thick sides, and the armor deck consisted of up to 60 mm thick armor plate.
