SMS Oldenburg[lower-alpha 1] was an armored warship of the German Imperial Navy. Laid down at the AG Vulcan shipyard in Stettin in 1883, the ship was launched in December 1884 and commissioned into the Navy in April 1886. Oldenburg was intended to have been a fifth member of the Sachsen class of sortie corvettes, but budgetary limitations and dissatisfaction with the Sachsen class prompted a redesign that bore little resemblance to the earlier vessels. Oldenburg mounted her main battery of eight 24 cm (9.4 in) guns amidships, six in a central casemate on the main deck and two directly above them on the broadside. She was the first German capital ship constructed entirely from German-made steel.

Oldenburg did not see significant service with the German Navy. She participated in fleet training maneuvers in the late-1880s and early 1890s, but she spent the majority of the 1890s in reserve. Her only major deployment came in 1897–1898 when she joined an international naval demonstration to protest the Greek annexation of Crete. In 1900, she was withdrawn from active duty and used as a harbor defense ship. From 1912 to 1919, she was used by the High Seas Fleet as a target ship; she was sold for scrapping in 1919 and broken up that year.

Design[]

Oldenburg was intended to be a fifth member of the Sachsen class of sortie corvettes. The design for the ship was radically altered,[1] between 1879 and 1881,[2] for a variety of reasons. The German Navy was largely dissatisfied with the Sachsen class ships, and a number of design faults required correction.[1] Budgetary constraints also limited the design of the ship,[3] forcing the design staff to work within a displacement some 2,000 t (2,000 long tons; 2,200 short tons) lower than that of the Sachsens.[4]

Assessment of the design is mixed; naval historian Erich Gröner states that Oldenburg was an "experimental design, of no real value in combat."[5] Conway's All the World's Fighting Ships concurs, stating that Oldenburg was "considered to be of little fighting value by the time she was completed."[3] The 1889 edition of the Brassey's Naval Annual reported a contradictory opinion, however, stating that "The majority of German naval critics are dissatisfied to a greater or less extent with all of these vessels, the König Wilhelm, Kaiser, Deutschland, and Oldenburg excepted."[6]

Line-drawing of Oldenburg

Oldenburg was 78.4 m (257 ft) long at the waterline and 79.8 m (262 ft) long overall. She had a beam of 18 m (59 ft) and a draft of 6.28 m (20.6 ft) forward and 6.3 m (21 ft) aft. At the designed displacement, the vessel displaced 5,249 metric tons (5,166 long tons; 5,786 short tons). When the ship was fully loaded, she displaced 5,743 t (5,652 long tons; 6,331 short tons).[5] Her hull was built with transverse and longitudinal steel frames; iron was used for the stem and stern. The ship had twelve watertight compartments and a double bottom that ran for 60 percent of the length of the hull.[2] Oldenburg was the first German capital ships built entirely from German-made steel.[7]

The German navy regarded Oldenburg as an adequate sea boat, though she suffered from significant pitching. As a result of her tendency to pitch severely, a 60 t (59 long tons; 66 short tons) ballast was permanently installed in the bow. She also lost a great deal of speed in heavy seas; at conditions above Beaufort sea state 6, this could be up to a 25 percent loss of speed. The ship could not operate under severe weather conditions. Her transverse metacentric height was .63 m (2 ft 1 in). Her standard complement consisted of 34 officers and 355 enlisted men, though her crew was later reorganized to 32 officers and 40 enlisted sailors. She carried a number of smaller boats, including one picket boat, one launch, two pinnaces, two cutters, two yawls, and one dinghy.[5]

Painting of Oldenburg in 1902

Oldenburg was powered by two horizontal 4-cylinder double expansion steam engines in separate engine roomes; the two engines each drove a three-bladed screw 4.5 m (15 ft) in diameter. Steam was provided to the engines by eight transverse cylinder boilers, divided into two boiler rooms. Each boiler was equipped with three fireboxes, for a total of 24, which operated at up to 5 standard atmospheres (510 kPa) forced. The engines were designed to operate at 3,900 indicated horsepower (2,900 kW) for a top speed of 14 knots (26 km/h; 16 mph). On speed trials, her engines slightly exceeded the designed horsepower, at 3,942 ihp (2,940 kW), though Oldenburg made only 13.8 kn (25.6 km/h; 15.9 mph).[5]

The ship was designed to store 348 t (343 long tons; 384 short tons) of coal, though she could accommodate up to 450 t (440 long tons; 500 short tons). An additional 120 t (120 long tons; 130 short tons) of coal could be stored on her deck. At a cruising speed of 9 kn (17 km/h; 10 mph), Oldenburg could steam for 1,770 nautical miles (3,280 km; 2,040 mi). Increasing her speed by one knot reduced her range to 1,370 nmi (2,540 km; 1,580 mi), and at 12 kn (22 km/h; 14 mph), she could cruise for only 980 nmi (1,810 km; 1,130 mi). Steering was controlled by a single rudder. She was equipped with three electrical generators with a total output of 29 kilowatts at 65 volts.[5]

Armament and armor[]

Oldenburg carried eight 24 cm (9.4 in) L/30 hooped guns in an unusual configuration: six guns on the main deck, one on each broadside, four in embrasures at each corner of the central battery to give a measure of end-on fire, and two on the upper deck firing broadside.[5][3] These guns were supplied with 494 rounds of ammunition, and could depress to −5° and elevate to 8°. This enabled a maximum range of 5,700 to 8,800 m (6,200 to 9,600 yd).[5] She was also equipped with four 15 cm (5.9 in) L/22 guns and two 8.7 cm (3.4 in) L/24 guns. Four 35 cm (14 in) torpedo tubes rounded out her armament. One was mounted in the bow, submerged, two were placed on the broadside above water, and the fourth was located in the stern, also above water. She carried ten torpedoes.[5][3]

Oldenburg's armor consisted of compound steel backed with teak; the steel was fabricated by the Dillinger Works.[7] The main armored belt was composed of two strakes; the steel upper strake was 300 mm (12 in) thick amidships, where it protected the ship's vitals. The belt was reduced on either end of the central portion to 200 mm (7.9 in). The lower strake was 250 mm (9.8 in) thick in the central section and 180 mm (7.1 in) on either end. The entire belt was backed with 250 mm of teak amidships and 300 mm of teak on either end. The sides of the armored casemates for the main battery were 150 mm (5.9 in) thick. The ship's deck was 30 mm (1.2 in) thick. Her forward conning tower had 50 mm (2.0 in) thick sides and a 25 mm (0.98 in) thick roof. The rear conning tower was given only splinter protection, with 15 mm (0.59 in) thick sides and a 12 mm (0.47 in) thick roof.[2]

SMS Oldenburg in port

Oldenburg was laid down in 1883 at the AG Vulcan shipyard in Stettin, under construction number 132. She was launched on 20 December 1884, after which fitting-out work commenced. She was completed by April 1886 and commissioned into the German Navy on 8 April.[5] She immediately joined the I Division of the fleet, alongside Sachsen, Bayern, and Württemberg, for the annual fleet maneuvers. Bayern and Württemberg suffered from engine troubles throughout the exercises, but Oldenburg performed satisfactorily.[8]

In June 1887, Germany dedicated the Kaiser Wilhelm Canal; Oldenburg was among the ships present during the celebrations. Oldenburg was assigned to the training squadron for the maneuvers in August–September 1887, along with König Wilhelm and Kaiser. The majority of the exercises were focused in the Baltic, but the fleet did conduct maneuvers in the North Sea for eight days in September.[9] Oldenburg also participated in the visit to Great Britain in August 1889, where Wilhelm II took part in the Cowes Regatta. The ship was assigned to the I Division with Sachsen, Baden, and the new cruiser Irene. Oldenburg and the rest of the fleet joined the Royal Navy in a fleet review for Queen Victoria.[10]

Oldenburg participated in the ceremonial transfer of the island of Helgoland from British to German control in the summer of 1890. She was present during the fleet maneuvers in September, where the entire eight-ship armored squadron simulated a Russian fleet blockading Kiel.[11] She remained with the I Division in 1891; the year's maneuvers simulated a two-front war against Russia and either France or Denmark. In 1892, however, Württemberg replaced Oldenburg in the I Division, and the latter went into reserve.[12] The ship remained out of service for the next five years. She returned to active duty in 1897 to join an international naval demonstration off the island of Crete, which had been annexed by Greece. The ship remained in the demonstration until March 1898, when Germany and Austria-Hungary withdrew their naval contingents in a show of dissatisfaction over the compromise solution, which left Crete under Ottoman control, but with a Greek prince.[13]

In 1900, Oldenburg was reduced to serve as a harbor guard ship. She was later used as a depot ship before being stricken from the naval register on 13 January 1912. The vessel was then used as a target ship by the High Seas Fleet until after the German defeat in World War I. Oldenburg was sold to Hattinger Company, a ship-breaking firm, on 5 May 1919. The ship was dismantled for scrap in Wilhelmshaven that year.[5]
