The primary change was an increase of the main battery from eight 35-centimeter (14 in) guns to eight 38 cm (15 in) weapons. The name derived from the fact that the lead ship was intended as a replacement (German: ersatz) for the armored cruiser Yorck lost to mines in 1914. [5] Exeter used a modified Mark II* mounting, limited to 50 degrees elevation.[6]. The guns could engage targets out to 13,500 m (44,300 ft), and after improvements in 1915, their range was extended to 16,800 m (55,100 ft). The design speed was 32.5 knots (60.2 km/h), one knot faster than the County class.[3]. There were three 60 cm (24 in) tubes: one in the bow, and one on each flank of the ship. The second ship of the Roon class, Yorck was built by a private firm instead of a government dockyard like the eponymous ship, and as a result Yorck was commissioned just two months after this photo, whereas Roon was not done until April 1906. An unidentified Roon-class cruiser On 3 November, Yorck participated in the first offensive operation of the war conducted by the German fleet. The belt was reduced in less critical areas, to 120 mm (4.7 in) forward and 100 mm (3.9 in) aft. [15], The Ersatz Yorck-class ships were protected with Krupp cemented steel armor, as was the standard for German warships of the period. Today I bring you another upgrade ship. [2], The economies in size allowed for a 50-foot (15 m) reduction in length and 9 feet (3 m) in beam over the Counties. [16], The contracts for the ships had originally been allocated while still members of the Mackensen class. The shell allotment was divided between armor piercing and high explosive versions, with 60 of the former and 30 of the latter. [2][5], As with all German battlecruisers that had been built, the Ersatz Yorck-class ships would have been equipped with four sets of Parsons steam turbines,[7] each of which drove a 3-bladed screw that was 4.2 m (13 ft 9 in) in diameter. The fourth and final Naval Law, passed in 1912, governed the building program of the German Navy during World War I. The guns had a sustained rate of fire of 5 to 7 rounds per minute. Their engines were identical - four boilers in two boiler rooms providing steam for four Parsons geared turbines, generating 80,000 shaft horsepower. The torpedoes had a range of 8,000 m (8,700 yd) when set at a speed of 35 knots (65 km/h; 40 mph); at a reduced speed of 28 knots (52 km/h; 32 mph), the range increased significantly to 15,000 m (16,000 yd). Yorck— German Tier VII cruiser. [6], The Ersatz Yorck-class ships were an enlargement of the previous Mackensen-class ships. The name derived from the fact that the lead ship was intended as a replacement (German: ersatz) for the armored cruiser Yorck, lost to mines in 1914, and it had been ordered under the provisional Ersatz Yorck. The Roon class was a pair of armored cruisers built for the German Imperial Navy after the turn of the 20th century. They were 227.8 m (747 ft 5 in) long at the waterline, compared to 223 m (731 ft 8 in) on the earlier vessels. The transmitting station was also covered by 1in armour. Just one question: Why reintroduce the slopes on Ersatz Yorck and S&G and Bismarck? The crew of the ship was to consist of 47 officers and 1,180 sailors. A 45 mm (1.8 in) torpedo bulkhead ran the length of the hull, several meters behind the main belt. The then called Yorck class also included 38 cm guns and were the first German capital ships with only one funnel. The ships were designed to store 850 t (840 long tons) of coal and 250 t (250 long tons) of oil in purpose-designed fuel bunkers. Work on the first ship had already begun by the time the navy decided to re-design the ships, so the design staff was constrained by the need to use the material already assembled. The Ersatz Yorck class was a group of three battlecruisers ordered but not completed for the German Kaiserliche Marine (Imperial Navy) in 1916. The Panzerschiffe are a special case, as they are not really battleships. The ships were easily distinguished from their predecessors by the addition of a fourth funnel. Compared to the County's, the Yorks saved 1,750 tons in net weight, but the reductions in cost of £250,000 and manpower of 50 was something of an uneconomical saving. [2][19], Already in 1918, the design staff revived the grosskampfschiff concept with a series of design studies that ranged from smaller counterparts to the British Courageous class of "large light cruisers" to very large, 45,000 t (44,000 long tons) battlecruisers armed with 42 cm (16.5 in) guns. Work on Ersatz Yorck began with her keel laying in July 1916 under yard number 63, and the midship section of the hull had been assembled by the time the ships were redesigned. She was designed in the interwar period for the Reichsmarine (which later became the Kriegsmarine) as one of the possible heavy cruiser designs that would later become the Deutschland Class Cruisers. [2], See also: List of ships of the Imperial German Navy. The design studies ultimately demonstrated that the type of ship that Scheer desired was impractical owing to the size limitations imposed by the German Navy's infrastructure, specifically the existing dry docks and the Kaiser Wilhelm Canal. The Imperial German Navy (Hochseeflotte), Yorck Information, Battlecruisers, Yorck, Schlachtkreuzer, Yorck class They were initially intended to favor high speed for reconnaissance over the heavier gun armament of the Cöln class, though by the final iterations, they were as powerful as the earlier class. by | Dec 26, 2020 | Uncategorized | 0 comments | Dec 26, 2020 | Uncategorized | 0 comments [2][3], Vizeadmiral (Vice Admiral) Reinhard Scheer, the commander of the High Seas Fleet, expressed his preference for GK2, the largest and fastest of the versions (with a top speed of 29.5 knots (54.6 km/h; 33.9 mph)), during a meeting on 29 April. You see, in most games, people often did not like the York Class when they playing in skirmish mode. World War 1 Service: Roon Nevertheless, the work that had gone into the Ersatz Yorck design was not a wasted effort; when the design staff began work on the Scharnhorst-class battleships in the 1930s, they used the plans for Ersatz Yorck as a starting point. Four were arranged around the rear superfiring main battery turret and the other four around the forward conning tower. Displacement rose about 2,500 t (2,500 long tons) compared to the Mackensen class, with about 1,000 t (980 long tons) of that increase being a result of the heavier 38 cm guns. Work on the first ship had already begun by the … On 19 April, the Construction Department submitted several design proposals, including GK1, GK2, and GK3. As a result of the magazine changes, and to keep the funnels distant from the bridge, only two funnels were required; the forward boiler room uptakes trunked up into a large fore-funnel. Admiral Eduard von Capelle replaced Grossadmiral (Grand Admiral) Alfred von Tirpitz as the State Secretary of the RMA on 16 March 1916, which led to questions in the RMA over the three ships. By that time, Ersatz Friedrich Carl had been laid down the previous November, and was too far along to be converted, leaving the last three Mackensens as the only members available to be rearmed. The three ships had originally been ordered as additions to the Mackensen class, but developments abroad, particularly the British Renown-class battlecruisers, led to the navy re-designing the ships. Owing to her well-balanced characteristics, the ship surpassed the first generation cruisers of her time, that were subject to the Washington Naval Treaty, in terms of protection, and light cruisers i Although it … The guns fired at a muzzle velocity of 835 metres per second (2,740 ft/s). The length and draft were also increased to keep the ships' speed from falling too much. SMS Ersatz Yorck class battlecruisers line drawing (1917 project). The three ships had originally been ordered as additions to the Mackensen class, but developments abroad, particularly the British Renown-class battlecruisers, led to the navy re-designing the ships. As with the Mackensens, the three ships of the Ersatz Yorck class were never completed. Laid down 16th May 1927, launched 17th February 1928, completed 6th June 1930. These turrets originally allowed for depression of the guns to −8 degrees and elevation to 16 degrees, though Bayern had hers modified to allow 20 degrees of elevation, a common practice for German naval weapons during the latter part of the war. York eventually received a rotating catapult amidships behind the funnels, and Exeter had a fixed pair in the same location, firing forwards and angled out from the centreline. These guns were intended for defense against torpedo boats, and were supplied with a total of 2,240 shells. The Ersatz Yorck class was a group of three battlecruisers ordered but not completed for the German Kaiserliche Marine (Imperial Navy) in 1916. Ersatz Yorck, a replacement for the armored cruiser Yorck, was awarded to AG Vulcan in Hamburg on 10 April 1915. The Ersatz Yorcks were intended to mount a pair of rudders side by side for steering. This weight saving was mainly to be accomplished by reducing the armament to six 8-in guns (as opposed to the 8 guns on the County class), and also by using a new Mark II mounting for the guns. This was because it had been intended to fit a catapult and floatplane to the roof of the turret, which needed clearance distance and required a tall bridge to provide forward view. The York class was the second and final class of 8-inch (203 mm)–gunned heavy cruisers built for the Royal Navy under the terms of the 1922 Washington Naval Treaty. The Ersatz Yorck class was a group of three battlecruisers ordered but not completed for the German Kaiserliche Marine (Imperial Navy) in 1916. [8], The Ersatz Yorck-class battlecruisers were to be armed with a main battery of eight 38 cm (15 in) SK L/45 guns in four Drh LC/1913 twin-gun turrets;[b] this was identical to the main armament carried by the Bayern-class battleships. Some material for Ersatz Gneisenau had been constructed, including the ship's diesel generators, which were subsequently installed in the first four Type U 151 U-boats U-151, U-152, U-153, and U-154. The big cruiser SMS Yorck belonged to the Roon class, which consisted of only two ships and were built shortly after the turn of the century. She combined the rapid-fire battery of light cruisers with the survivability of heavy ones. Another meeting on 24 August concluded that all seven ships of the Mackensen class would be built as designed, the General Navy Department noting that they would "still undoubtedly represent a very valuable addition to the fleet in 1919. The rear conning tower was less well armored; its sides were only 200 mm (7.9 in) and the roof was covered with 50 mm (2 in) of armor plate. 1 Overview 2 Ships in Class 2.1 HMS York (90) 2.2 HMS Exeter (68) The York-Class heavy cruiser. [2][14] The ships would have been supplied with approximately fifteen torpedoes. The Reichsmarineamt (RMA – Imperial Naval Office) decided that to meet the requirements set in the 1912 law, the Navy should construct one battleship and one battlecruiser every year between 1913 and 1917, with an additional unit of both types in 1913 and 1916. The Ersatz Yorck class was a group of three battlecruisers ordered for the Imperial German Navy in April 1915. [d] The RMA filed a report dated 1 February 1918, which stated that capital ship construction had stopped, primarily due to the shifting priorities to the U-boat war. [2] To shorten the belt length, the amidship magazine found on the Counties was removed (reduced armament required less magazine space anyway). The six 8 inch Mark VIII guns were mounted in three turrets. Only light cruisers would be built: The two Graudenz (1914-1915), two Pillau (1914-1915), two minelayers Brummer class (1916), two Wiesbaden class (1915), four Königsberg-II (1915-1916), and two Cöln-II (1918). The guns had a rate of fire of around one shell every 38 seconds. This was similar to the County class, with the exception that the Yorks carried two fewer torpedo tubes, because of the narrower beam. The belt tapered down to 30 mm (1.2 in) at the bow, though the stern was not protected by armor at all. Both ships served in vigorously in the first few years of World War II. The guns had a maximum range of 20,250 m (66,440 ft). The turbines were supplied with steam by 24 coal-fired Schulz-Thornycroft single-ended boilers and 8 oil-fired Schulz-Thornycroft double-ended boilers. [2][7], The power plant was rated 90,000 shaft horsepower (67,000 kW; 91,000 PS) and 295 revolutions per minute, the same as the preceding Mackensen-class ships. Over the magazine spaces, the belt thickened to 4in, and the armour extended above the belt, with a 2.5-in magazine crown The turrets had 2in armour to the face and crown, 1.5in on sides and rear, and the barbettes on which the turrets sat had 1in armour. The ships were to have electrical power provided by diesel generators. The torpedoes were the H8 type, which were 9 m (30 ft) long and carried a 210 kg (463 lb) hexanite warhead. Warning: Display title "York class cruiser" overrides earlier display title "York-class cruiser". Sunk in surface action, 1st of March 1942. [2][5], The ships were never completed, primarily because by 1917, the shipbuilding industry had largely been diverted to support the U-boat Campaign, which had become the priority of the Navy. armored cruiser yorck. The main battery gun turrets were also heavily armored: the turret sides were 270 mm (11 in) thick and the roofs were 110 mm (4.3 in). Crew 633. The hulls were divided into eighteen watertight compartments. SMS Yorck has been listed as one of the Warfare good articles under the good article criteria.If you can improve it further, please do so. The 15 cm guns had 150 mm worth of armor plating in the casemates; the guns themselves had 70 mm (2.8 in) shields to protect their crews from shell splinters. The ships were also to be equipped with eight 8.8 cm (3.5 in) SK L/45 flak guns in single pedestal mounts. British heavy cruiser HMS York (C90) at Vancouver on August 10th, 1938.. She augmented the forces assigned to the I Scouting Group , which primarily consisted of the battlecruisers Seydlitz , Moltke , and Von der Tann and the large armored cruiser … By this time, much of the construction resources of the German Navy had been redirected to the U-boat fleet, so the new ships could not be completed before 1920; as a result, the Mackensens would be inferior to the latest American and British designs. When Germany learned of the construction of new British battlecruisers with 38,1 guns in 1916 (Renown and Repulse), the three last ships of the Mackensen class were modified to match the new British designs. Ultimately, both ships were lost in action by early 1942. The shells were 45.3 kg (100 lb), and were loaded with a 13.7 kg (30 lb) RPC/12 propellant charge in a brass cartridge. [4] The Mark II mounting was capable of firing at up to 80 degrees elevation for anti-aircraft barrage fire. The roof of the turret, however, was not sufficiently strong to carry this catapult and it was never fitted. Kaiser Wilhelm II wanted the next group of battlecruisers to be equipped with 38-centimeter (15 in) guns instead of the 35 cm (14 in) pieces carried by the Mackensens. They were essentially a reduced version of the preceding County class, scaled down to enable more cruisers to be built from the limited defence budgets of the late 1920s. Select Page. "GK" stood for "Grosse Kreuzer" (large cruiser), the German term for battlecruisers at the time. [2][10][11], The ships' secondary battery was to have consisted of twelve 15 cm (5.9 in) SK L/45 quick-firing guns mounted in armored casemates along the central superstructure. Ersatz Yorck had the same beam as the earlier vessels, at 30.4 m (99 ft 9 in), and the same maximum draft of 9.3 m (30 ft 6 in). Some consideration was given to the idea that the new battlecruiser design should represent a merging of the battleship and battlecruiser types—what was later termed a "fast battleship"—a concept Wilhelm II had been pushing for years. The other two ships, Ersatz Gneisenau, and Ersatz Scharnhorst, were considered to be replacements for the armored cruisers Gneisenau and Scharnhorst, both of which had been sunk at the Battle of the Falkland Islands, also in 1914. No work was done on Ersatz Scharnhorst before the ships were cancelled. Most famously, Exeter took part in the Battle of the River Plate against the German raider Graf Spee, and was badly damaged, though later repaired and extensively modernized. Intended ammunition stowage for the Ersatz Yorck class was 720 shells or 90 rounds per gun; these were 750-kilogram (1,650 lb) shells that were light for guns of their caliber. Mainz — German premium Tier VIII cruiser. They were essentially a reduced version of the preceding County class, scaled down to enable more cruisers to be built from the limited defence budgets of the late 1920s. The last three of these new battlecruisers were ordered to replace Yorck and the two Scharnhorst-class cruisers, the former having been sunk by German mines in November 1914 and the latter pair being sunk at the Battle of the Falkland Islands the following month.
