Wilhelm I Class (1907)
The first all-gun dreadnought for Großdeutschland, the Wilhelm I class replaces the Nassau class in OTL. It is based upon Ersatz-Bayern Scheme G7b (dated February 1906) - albeit slightly longer - and he is armed with twelve 28cm SK L/40 in a hexagonal arrangement, twelve 15cm SK L/45 on the broadsides, and twenty 8.8cm SK L/45 guns for the tertiary battery. In addition, there were five 45cm torpedo tubes (2 on each broadside, and one at the bow). The maximum design speed attainable was given as 19.8 knots maximum, although most ships of the class pushed just above 20 knots on trial runs.
The four ships were laid down as a response to the British Dreadnought-class ships being built at the time. They were named:
Wilhelm I,
Friederich Wilhelm III,
Heinrich VI, and
Friedrich Barbarossa. They were commissioned in 1909-1910, being built at Kaiserliche Werft, AG Weser, AG Vulcan, and Germaniawerft respectively. The ships were nearly 1,000 tons heavier than their adversaries, and well armored. Main belt armor was 24cm thick, tapering to 10cm at the extremities, 3cm deck, 25cm thick turrets (and ~20cm to ~23cm for the barbettes), and a 25cm armor protection for the conning tower.
Service in Der Ester Weltkrieg
Together,
Wilhelm I,
Friederich Wilhelm III,
Heinrich VI, and
Friedrich Barbarossa made up the 1st Battle Squadron (the later Sachsen class would comprise of the 2nd Battle Squadron), After the outbreak of the war in 1914, the first major operation which the ships participated in was the November 2-3 raid on Scarborough. However, no contact was made between fleets, and another operation was launched at the beginning of December. In this operation, twelve dreadnoughts, and twelve pre-dreadnoughts of the Hochseefleet participated - in addition to the accompanying screen of cruisers and destroyers. The British were informed of the attack, but were not sure of the precise location, but yet set out in search of them with the 1st Battlecruiser Squadron, and 8 battleships of the 2nd Battleship Squadron, along with a screen of cruisers and destroyers as well. Their mission was to engage and destroy the German 1st Battlecruiser Squadron, but Task Force Beatty ended up running into nearly the entire Hochseefleet battleline in the early hours of the morning.
In the intense 2-hour melee that followed, the British screening force duked it out with the German curtain of cruisers destroyers, at times what was - literally - point-blank range. The British destroyers moved in for a torpedo attack, and one of them,
HMS Acasta (the lead ship of her class), fired several torpedoes at
Friedrich Wilhelm III (which she somehow mistook for a light cruiser!) and even fired her main guns as she closed the range. However, as she pressed the attack,
Friedrich Wilhelm III maneuvered to ram the smaller vessel.
Acasta was able to make a hard to starboard maneuver at the last moment, with the left side of the bows of each ship colliding with one another. As the destroyer passed under the larger ship, SMS Friedrich Wilhelm III fired her main 28cm cannons, blowing off the front torpedo tubes with the gasses of its heavy weapons. This caused the captain of the ship to crouch down, and as he did, the shell literally grazed over his head, how he managed to survive that must have been due to an extraordinary amount of luck! After the collision,
Acasta managed to stagger away from the main German battle line, and the damage to the pre-dreadnought was surprisingly minimal, although there was a huge gash across the length of her forecastle.
Both ships survived the engagement, though not unscathed of course. At sunrise, Beatty's forces disengaged, leaving behind a pair of armored cruisers, a light cruiser, and a trio of destroyers that were burning or sinking. On the German side, there was a loss of 4 torpedo-boats, and 3 damaged cruisers (some heavily). Tactically, it was a German victory, but neither side achieved their objective of crippling or sinking the other side's capital ships. The
Wilhelm I class would have a fairly distinguished career, being at the forefront of many sorties and engagements at the beginning of the war. However as the war carried on, they were regulated to more coastal defense ships, as bigger and better capital ships were commissioned into the Reichsmarine. Below is the evolution of the ships through their service careers (the first and last pairs being similar to one another). At war's end, they were converted into Mutterschiffe fur F-Boote, with Heinrich VI and Friedrich Barbarossa differing slightly in their get-up.
