Pre-dreadnought
Pre-dreadnought battleship is the general term for all of the types of sea-going battleships built between the mid-1890s and 1905. Pre-dreadnoughts replaced the ironclad warships of the 1870s and 1880s...

General characteristics

The Braunschweig class ships were 413 ft 3 in long at the waterline, and 419 ft (127.7 m) overall. The ships had a beam of 73 ft (22.3 m), and a draft of 26 in 7 in (8.1 m). The ships had thirteen watertight compartments and a double bottom

s at their designed weight, and 14,394 t at a full load.

The ships were described as good sea-boats, but were prone to heavy pitching. The ships were responsive and had a tight turning radius at low speed, but at hard rudder of 12 degrees, the ships lost up to 70 percent speed. The ships had a crew of 35 officers and 708 men normally, and when serving as a squadron flagship, they had an additional 13 officers and 66 men. The ships carried a number of smaller boats aboard, including two picket boats, two launches

Propulsion

The ships of the Braunschweig class were propelled by three shaft triple expansion engines that were rated at 16000 ihp. The triple expansion engines were powered by eight Marine type boilers and six cylinder boilers. After 1915, oil-firing capability was added to supplement the coal-fired boilers.Wartime shortages in high-quality coal meant only poor-quality, low-efficiency coal was available. In order to maintain engine power, oil would be sprayed onto the coal in order to increase its burn rate. The ships had a single rudder and three screws. The two outer propellers were three-bladed, and 4.8 m (5.24 yd) in diameter. The center screw was four-bladed and 4.5 m (4.92 yd) in diameter. The ships' top speed was rated at 18 knots (35.3 km/h). During trials, however, the engines produced between 16400 ihp, and a top speed between 18.2 and 18.7 kn (35.7 and 36.6 km/h). The ships of the class could steam 5,200 nautical miles (10,000 km) at a cruising speed of 10 knots (20 km/h), with the exception of Hessen. Hessen suffered from unstable steering, which increased fuel consumption and shortened her operational range to 4530 nmi (8,389.6 km) at 10 knots (19.6 km/h). The first two ships—Braunschweig and Elsass had four generators that produced 230 kW (74 V), while three following ships—Hessen, Preussen, and Lothringen had four turbo-generators that provided 260 kW (110 V).

Armor

The ships were equipped with Krupp armor. The deck armor was 40 mm (1.57 in) thick on the horizontal, and ranged between 140–75–140 mm (5.51–2.95–5.51 in) in the sloped deck armor. The main armored belt

 had a 50 mm (1.97 in) thick roof, while the sides were 300 mm (11.8 in) thick. The aft conning tower had a roof protected by 30 mm (1.2 in) of armor plating and 140 mm (5.51 in) armor on the sides. The ship's citadel was also protected by 140 mm of armor. The main battery turrets had 50 mm thick roofs and 250 mm sides. The secondary battery turrets were protected by 150 mm (5.9 in) of armor, while the casemated guns had gun shields 70 mm (2.75 in) thick.

Armament

The ships' main armament was increased from previous designs, but still weaker than contemporary foreign battleships. The main armament comprised four 28 cm (11 in) SK L/40

, increased from four 24 cm (9.4 in) guns from previous designs, compared with the 12 in (30.5 cm) guns used on many foreign ships. The guns could depress down to −4 degrees, and elevate to +30 degrees, which enabled a maximum range of 18,800 m (20,600 yd). The guns fired 529 lb shells at a muzzle velocity of 2690 feet per second (820 m/s) The main battery had a total of 340 shells, for 85 shells per gun.

The secondary battery consisted of fourteen 17 cm (6.7 in) SK L/40 quick-firing guns, four of which were mounted in single turrets amidships, with the remaining ten in casemates around the superstructure. The guns fired 141 lb shells at a muzzle velocity of 2789 f/s (850 m/s). The turret-mounted guns could be elevated to 30 degrees, for a maximum range of 16,900 m (18,500 yds), while the casemated guns could only elevate to 22 degrees, and had a correspondingly lower range of 14,500  m (15,850 yd). These guns had a total of 1820 shells, for 130 rounds per gun. To transit the Kiel Canal

, the three central 17 cm casemated guns had to be withdrawn into their housings, as they were unable to train fully flush with the sides of the ships. With the guns fully emplaced, the ships would have been too wide to fit in the canal.

Starting in 1916, the ships of the Braunschweig class were withdrawn from active service, primarily because of manpower shortages. Braunschweig was used as a training ship, and on 20 August 1917, was converted into a barracks ship in Kiel. Elsaß was also used as a barracks and training ship in Kiel, having been withdrawn from active service on 25 July 1916. Hessen was converted into a depot ship in Brunsbüttel in 1917, while Preussen became a depot ship in Wilhelmshaven that same year. Lothringen was withdrawn from service in 1917 and used as an engineer training ship in Wilhelmshaven.
