Design

The ships of the Wittelsbach-class were the first battleships built under the first Naval Law of 1898. The ships represented an incremental improvement over the preceding Kaiser Friedrich III-class. They were equipped with the same armament of 24 cm guns, but were given an additional torpedo tube. They also had improved defensive capabilities, as they were protected by a more extensive armored belt. They also differed from the preceding ships in their main deck, the entire length of which was flush; in the Kaiser Friedrich III-class ships, the quarterdeck

The hull was split into 14 watertight compartments and included a double bottom

The ships were regarded in the German Navy as excellent sea boats with an easy roll; the ships rolled up to 30° with a period of 10 seconds. They maneuvered easily; at hard rudder the ships lost up to 60 percent speed and heeled over 9°. However, they suffered from severe vibration, particularly at the stern, at high speeds. They also had very wet bows, even in moderate seas. The ships had a crew of 33 officers and 650 enlisted men. However, when serving as a squadron flagship

Propulsion

The five ships of the Wittelsbach-class each had three three-cylinder triple expansion steam engines. The outer engines drove a three-bladed screw that was 4.8 m (15.7 ft) in diameter; the central shaft drove a four-bladed screw that was slightly smaller, at 4.5 m (14.8 ft) in diameter. To produce steam to power the engines, each ship had six marine-type boiler

The propulsion system was rated at 14000 ihp, which produced a top speed of 18 knots (9.8 m/s). On trials, however, the five ships had significantly varied performances. Schwaben, the slowest ship, reached 13253 ihp for a top speed of only 16.9 knots. Wettin, the fastest, managed 15530 ihp and a top speed of 18.1 knots. They carried 650 tonnes (640 LT) in their holds, but fuel capacity could be nearly tripled to 1800 tonnes (1,772 LT) with the usage of additional spaces in the ships. This provided a maximum range of 5000 nautical miles (9,260 km) at a cruising speed of 10 kn (5.4 m/s). Electrical power was supplied by four generators that each produced 230 kW at 74 volt

Armament

The ships carried 120 shells per gun, for a total of 2,160 rounds total. The guns could depress to −7 degrees and elevate to 20 degrees, for a maximum range of 13,700 m (14,990 yd). They were manually elevated and trained.

The ships also carried twelve 8.8 cm (3.45 in) SK L/30 quick-firing guns, also mounted in casemates and pivot mounts. These guns were supplied with between 170 and 250 shells per gun. These guns fired 13.8 kg (30.4 lb) at a muzzle velocity of 590 mps (1,936 fps). Their rate of fire was approximately 15 shells per minute; the guns could engage targets out to 10,500 m (11,480 yd).

The ships were also armed with six 45 cm (17.7 in) torpedo tubes, all in above-water swivel mounts. Four tubes were mounted on the sides of the ship, another in the bow, and the last in the stern. These weapons were 5.1 m (201 in) long and carried a 87.5 kg (193 lb) TNT warhead. They could be set at two speeds for different ranges. At 26 kn (14.2 m/s), the torpedoes had a range of 800 m (870 yd). At an increased speed of 32 kn (17.4 m/s), the range was reduced to 500 m (550 yb).

 steel. Their armored decks were 50 millimetres (2 in) thick, with sloped sides that ranged in thickness from 75 to 120 mm (3 to 4.7 in). The sloped section of the deck connected it to the main armored belt, which was 225 mm (8.9 in) in the central citadel, where the ship's vitals were. This included ammunition magazines and the propulsion system. The belt was reduced to 100 mm (3.9 in) on either end of the central citadel; the bow and stern were not protected with any armor. The entire length of belt was backed by 100 mm of teak

Directly above the main belt, the 15 cm casemate guns were protected with 140 mm (5.5 in) thick steel plating. The 15 cm guns in turrets were more exposed and therefore slightly better protected: their side armor was increased to 150 mm (5.9 in), with 70 mm (2.8 in) thick gun shields.

This included the installation of the ship's armament, completion of the interior compartments, and the finishing of the superstructure. By late 1902 work on the ship was finished.

Zähringen was laid down at the Germaniawerft dockyard in Kiel under the provisional name "E" in 1899. She was launched on 12 June 1901 and commissioned in to the fleet on 25 October 1902. In 1900, Schwaben followed Wittelsbach at the Kaiserliche Werft Wilhelmshaven, under the provisional name "G." She was launched on 19 August 1901 and commissioned on 13 April 1904, the last ship of the five to join the fleet. Mecklenburg was ordered from the AG Vulcan shipyard in Stettin under the contract name "F." Her keel was laid there in 1900. Launched on 9 November 1901, Mecklenburg was completed by May 1903 and commissioned on the 25th.

The ships were based in Kiel and placed under the command of Vice Admiral Ehrhard Schmidt. In early September 1914, the ships conducted a result-less sweep into the Baltic against the Russian navy operating there. In May 1915, four of the Wittelsbachs sailed into the Baltic and bombarded Libau

British submarines were becoming increasingly active in the Baltic by late 1915; several cruisers had been sunk and the elderly Wittelsbach-class ships could no longer be risked there. Therefore, due to their age and vulnerability, they were withdrawn from active service and disarmed by 1916. They were used as training ships, with the exception of Mecklenburg, which was used as a prison ship. In 1919, Wittelsbach and Schwaben were converted into depot ship
