The Hohenzollern was a ship built as a state yacht of the German Empire . It was supposed to replace its predecessor of the same name , but was no longer completed after the outbreak of the First World War .
construction
Due to the advancing age of the imperial yacht, launched in 1892, a replacement became necessary in the early 1910s. Accordingly, the plans for a new yacht were drawn up in 1912 and 1913. The construction contract was awarded to the Stettiner Werft AG Vulcan , which in 1913 still stretched the keel for the ship. The launch planned for August 3, 1914 was delayed by strikes at the shipyard and could only take place on September 29. At that time, around 4,000 t of material had been installed, the boilers and turbines as well as the interior fittings were still missing. Due to the outbreak of war, the usual celebrations during the launch were dispensed with, which meant that the actual ship christening did not take place. The ship was eight months from completion. A further construction of the Hohenzollern was not carried out, the yacht was instead towed into a branch of the Oder in order to keep the berth in Stettin free for active ships.
technology
The Hohenzollern was designed as a transverse and longitudinal frame steel construction. With a design displacement of 7,324 t, the maximum displacement of the operational ship would have been 8094 t. The hull was 137.4 m long and 19 m wide. With maximum displacement, the yacht would have had a draft of 6.1 m forward and 6.4 m aft .
The electrical equipment of the ship should be at a voltage of 225 V to operate. To power two were turbine-driven generators with 100 kW and two diesel-powered generators, each with 60 kW power provided, making a total output would have been of 320 kW.
The crew of the Hohenzollern should consist of 15 officers and 435 men .
Propulsion system
As machinery were originally two by AEG provided and the AG Vulcan turbines manufactured by two Föttinger - torque converter on four screws should work with both 2.2 m in diameter. However, at the proposal of the shipyard, the plans were changed. Ultimately, three AEG Vulcan turbines should act directly on a screw with a 2.2 m diameter each. A separate engine room was provided for each turbine, with the two outer ones located next to each other and in front of the central turbine. The power of the machine system was calculated to be 16,700 hp . The Hohenzollern should be able to reach a top speed of 21 knots . In the event that the ship should remain below the contractually agreed value, AG Vulcan was obliged to convert the yacht to the original plan within 16 months at its own expense.
The steam supply was to be provided by eight coal-fired marine boilers and two oil-fired marine double boilers, which were designed for a steam pressure of 16 atmospheres . The coal-fired boilers would have had a total heating surface of 2700 m² and 16 furnaces, the heating surface of the oil-fired boilers would have been 1766 m². The ten boilers should be divided into five boiler rooms one behind the other. The fuel supply of 1000 t of coal and 520 t of oil was calculated in such a way that the Hohenzollern had a range of 2000 nm at a cruising speed of 19 knots.
Armament
Like the previous state yachts, armament was also planned for the third Hohenzollern . This should consist of four 10.5-cm L / 45 - quick-charging guns as well as four 5.2-cm-L / 55- aircraft guns consist. An ammunition reserve of 600 rounds each was provided for both types of gun. However, two of the flak should only be installed on board in the event of mobilization .
Whereabouts
A completion of the Hohenzollern did not take place after the end of the First World War. The unfinished ship was instead removed from the list of warships on November 17, 1919 and moved to Kiel in 1920 . Originally existing plans to use it as an exhibition ship were dropped. In 1923 the hull was sold and dismantled by the Deutsche Werke in Kiel.
