Design
The design for what was to become the Brandenburg class was prepared by Chief Constructor Alfred Dietrich; he originally used Oldenburg as a starting point. In his first memorandum on the project, he noted that the Oldenburg design would have to be enlarged to provide room for more powerful propulsion machinery and increased coal storage, and armor would have to be strengthened, among other changes. Displacement was originally fixed at 8,500 t (8,400 long tons). In a subsequent memorandum dated 8 August 1888, Dietrich raised the possibility of increasing the caliber of the main battery from 24 cm (9.4 in) to 26 cm (10 in). Dietrich met with Monts on 15 August, who requested that the new ship be armed with four 28 cm (11 in) guns, since the 26 cm guns were perceived to be too small to effectively engage the latest Russian ships being built. This version was submitted two days later to Wilhelm II, who approved it.[9][10]
Dietrich initially considered the latest Russian battleships being built—the
As Dietrich continued to work on the plans, he examined other foreign contemporaries, including the French
The Brandenburgs were the first ocean-going capital ships to be built for the German fleet in almost twenty years. Their construction caused significant concern in Russia, which was a possible naval opponent in the Baltic Sea; the Russians decided to strengthen their Baltic Fleet with as many as ten new battleships, though funding proved to be insufficient and the program was significantly pared down. The Brandenburg class was significantly smaller and less powerful than the contemporary British Royal Sovereign class, but roughly equal with the series of French battleships begun with Charles Martel and with the Russian Navarin (the French ships being faster but much less heavily armed and the Russian ship being slower but armed with heavier main guns).[16] Though they were the first modern battleships built in Germany, presaging the Tirpitz-era High Seas Fleet, the authorization for the ships came as part of a construction program that reflected the strategic and tactical confusion of the 1880s caused by theories like the Jeune École.[17]
General characteristics
The ships of the Brandenburg class were 108 m (354 ft 4 in)
The German navy regarded the ships as excellent sea-boats and the Brandenburgs had easy motion. They were also responsive to commands from the bridge and had a moderate turning circle. Despite their generally positive handling characteristics, the ships were "wet" at high speeds despite the forecastle deck and suffered from severe pitching. The ships lost up to 30% of their speed at hard rudder. Their metacentric height was 1.05 m (3 ft 5 in), and their maximum stability moment was 31.5 degrees.[18]
The ships' crew numbered 38 officers and 530 enlisted men, though while serving as the squadron flagship the standard crew was augmented by an additional 9 officers and 54 men. After their refits, their standard crew consisted of 30 officers and 561 enlisted sailors, with an additional 9 officers and 48 enlisted men as flagships. They carried a number of small boats, including a pair of picket boats, two launches, one pinnace, two cutters, two yawls, and two dinghies.[20]
Machinery
The ships' propulsion system consisted of two 3-cylinder
The engines were rated at 10,000
Armament
Main battery
The Brandenburg-class battleships carried a battery of six 28 cm guns of two different calibers; the forward and aft turrets mounted 40-caliber guns while the
The 35-caliber guns had a muzzle velocity of 685 m/s (2,250 ft/s), while the longer guns had a velocity of 715 m/s (2,350 ft/s); the differing velocities produced different ballistics, but the designers were not concerned with the problem, owing to the short ranges at which the ships were expected to fight and the primitive state of fire control in the 1880s. Propellant charges consisted of brown powder. Both types of guns used the same C/92 barbette mount that allowed for depression to −4 degrees and elevation to 25 degrees. The 35-caliber guns had a maximum range of 11,450 m (37,570 ft), while the higher velocity of the longer guns increased their range to 15,090 m (49,510 ft).[8][18][22]
The turrets were hydraulically operated and required the rotating gun houses to return to the centerline to reload the guns.[22] In their original configuration, the guns had a rate of fire of one shot every three minutes, but after their refits in the early 1900s, the ships' loading equipment was modernized to improve the rate to one shot per minute.[21] Ammunition magazines stored a total of 352 shells; these were 240 kg (530 lb) projectiles that had a 56.6 kg (125 lb) bursting charge.[18][22]
Secondary and tertiary guns
The Brandenburg class's
For close-range defense against torpedo boats, the ships also carried eight 8.8 cm (3.5 in) SK L/30 quick-firing guns. These were also mounted in casemates, four in sponsons abreast the forward main battery turret and four in the rear superstructure. They were carried in MPL C/89 mounts with an elevation range of −10 to 20 degrees; at maximum elevation, the guns could reach targets at 7,300 m (24,000 ft). Muzzle velocity was 590 m/s (1,900 ft/s). These guns were supplied with a total of 2,000 shells, though as with the 10.5 cm guns, ammunition storage was increased during the modernization, to 2,384 rounds. These were originally all C/83 common shells, though they were replaced by C/01 semi-armor-piercing (SAP) shells in 1901, and C/07 shells in 1907, which came in HE and SAP varieties.[18][25] Rate of fire was theoretically fourteen shots per minute, but in practice it was limited to ten rounds per minute.[26]
Torpedo tubes
In the 1880s, naval tacticians assumed most battles would devolve into a close-range melee, where torpedoes would become the decisive weapon, since they could damage a heavily armored ship below the waterline where the belt armor did not protect it. While the ships were under construction, Hollmann argued in a February 1891 memorandum that the original torpedo armament was not sufficient. He suggested that two torpedo tubes should be installed in the bow below the waterline to increase the forward firepower in the expected melee. There was no room in the bow to fit two torpedo tubes, however, so they were fitted in above-water mounts. At the same time, many foreign navies were adopting larger torpedoes, including the Royal Navy, which had shifted from its standard 35.6 cm (14 in) torpedo to a 45 cm (17.7 in) version. The Germans followed suit; the older 35 cm (14 in) C/84 torpedo was replaced with a much more powerful 45 cm C/91 version.[27]
The ships received six 45 cm torpedo tubes, four of which were mounted on the sides of the ship in above-water swivel mounts. The other two were in the bow, also above the waterline. The tubes were supplied with a total of 16 torpedoes, which carried a 87.5 kg (193 lb) warhead. They had a top speed of 32 knots (59 km/h; 37 mph) compared to the 24-knot (44 km/h; 28 mph) speed of the C/84 torpedoes; this allowed the torpedoes to travel 400 m (1,300 ft) in 24 seconds instead of the 30 seconds it would have taken the older torpedoes, making aiming at moving targets significantly easier.[18][28] Their maximum range at 32 knots was 500 m (1,600 ft); when set to 26 knots (48 km/h; 30 mph), their range increased to 800 m (2,600 ft).[29]
Armor
The first two ships, Brandenburg and Wörth, received
The side protection system followed the so-called "French principle", using a narrow, full-length armored belt to protect the hull, rather than a shorter citadel system that only protected a ship's ammunition magazines and propulsion machinery spaces. The belt extended from 0.8 m (2 ft 7 in) above the waterline to 1.6 m (5 ft 3 in) below, though toward the bow it was extended further down to reinforce the ram. Above the waterline, the armored belt was 300 mm (11.8 in) forward and as the belt moved further aft, it stepped up to 330 mm (13 in), then to 380 mm (15 in), and finally to 400 mm (15.7 in) in the central portion of the ship where it protected the magazines and machinery spaces. Further aft, it tapered to 350 mm (13.8 in) and then to 300 mm toward the stern. Below the waterline, the armored belt was significantly thinner; like the upper belt, it tapered toward the ends. It started at 150 mm (5.9 in) at the bow, increasing to 180 mm (7.1 in), then to 190 mm (7.5 in), and then to 200 mm (7.9 in) thick amidships, and tapered down to 180 mm (7.1 in) on the aft end of the belt. The teak backing for the belt amounted to 200 mm, and the whole assembly was bolted together.[32]
The Brandenburgs had an armored deck 60 mm (2.4 in) thick that was connected to the upper edge of the belt; it was effective only at deflecting short-range shells and could not have resisted plunging fire or a shell that detonated on impact. The forward conning tower had 300 mm sides and a 30 mm (1.2 in) roof. The barbettes for the main battery turrets were 300 mm thick and backed with 210 mm (8.3 in) of teak. The gun houses for the main battery had 50 mm (2 in) roofs and sides that consisted of three 40 mm (1.6 in) layers, for a total of 120 mm (4.7 in). The 10.5 cm and 8.8 cm guns received gun shields that consisted of two plates of steel bolted together; each shield consisted of a 20 mm (0.79 in) plate and a 22 mm (0.87 in) plate.[18][33]
Modifications
Over the course of their careers, the ships underwent a series of modifications. After entering service in 1894–1895, the vessels had their funnels increased in height by 1.5 to 3 m (4 ft 11 in to 9 ft 10 in) to reduce smoke interference with the mainmast spotting top.
Between 1902 and 1904, the four ships were extensively modified. During the modernization, a second, armored conning tower was added in the aft superstructure, along with a gangway. The new tower had sides 120 mm (4.7 in) thick and a 20 mm (0.79 in) roof. The work included increasing the ship's coal storage capacity and adding another pair of 10.5 cm guns. The plans had initially called for the center 28 cm turret to be replaced with an armored battery of medium-caliber guns, but this proved to be prohibitively expensive. The ships' torpedo armament was significantly reduced; two of the broadside tubes were removed, as were both bow tubes, while one above-water tube was installed in the stern in a trainable mounting. Total torpedo storage amounted to five torpedoes. Their masts had their searchlight platforms removed. The refit reduced the ships' displacement by 500 to 700 t (490 to 690 long tons).[20][36][37][38]
Later in her career, Wörth received two searchlights mounted on the roof of the fighting top of her foremast, along with a third on the roof of her aft bridge. An enclosed spotting top was installed in 1915. Both she and Brandenburg were disarmed in 1916 after they were removed from active service.[34]

After returning from China, the ships resumed their typical peacetime routine. By this time, the Kaiser Friedrich III and Wittelsbach classes of battleships had begun to enter service, so the four Brandenburgs were decommissioned to be modernized. By late 1907, all four members of the class were reduced to the Reserve Squadron, with Kurfürst Friedrich Wilhelm again serving as the flagship. The ships operated together there for the following three years before Kurfürst Friedrich Wilhelm and Weissenburg were sold to the Ottoman Empire in September 1910.[36][37][38]
Brandenburg and Wörth
Brandenburg and Wörth remained in the Reserve Squadron through 1911, being periodically reactivated to participate in annual fleet maneuvers in III Squadron. Brandenburg briefly served with the Training and Experimental Ships Unit in mid-1911. At the end of the year, they were decommissioned once again, their place in the unit being taken by other battleships as the latest

Turgut Reis was again decommissioned in October and remained out of service until she underwent a refit in 1924–1925, thereafter serving as a training ship, by this time with only one of her main battery turrets aboard the vessel. Decommissioned for the final time in 1933, she spent the next seventeen years as a barracks ship, ultimately being slowly broken up between 1950 and 1957.[63][64]

Notes
- ^ In Imperial German Navy gun nomenclature, "MRK" stands for Marine Ring Kanone, meaning that it was a naval gun of built-up construction, while the L/35 denotes the length of the gun. In this case, the L/35 gun is 35 caliber, meaning that the gun barrel is 35 times as long as it is in diameter.[13]
