Mainz — German promo premium Tier VIII cruiser.
The project of a cruiser with 150 mm guns (cruiser K), which was developed in the mid-1930s on the basis of the Admiral Hipper-class ships, shortly after the construction of the latter began. She combined the rapid-fire battery of light cruisers with the survivability of heavy ones.

Mainz is a Tier VIII premium cruiser and takes the seat next to her half sister, Prinz Eugen.
Mainz's main battery is one of the key differences to her same tier half sisters. Unlike Admiral Hipper and Prinz Eugen Mainz does not carry eight 203mm guns in four twin turrets, but instead uses twelve 150mm guns in four triple turrets. The guns and turrets that she has equipped are identical to those found on Tier VI Nürnberg. As such they also benefit from the baked in 1/4 HE penetration, which helps Mainz penetrate the hull plating of Tier VIII to X battleships, whereas other light cruisers are required to equip IFHE to achieve similar results. This results in four captain skill points that don’t have to be spent on said captain skill as well as avoiding the -50% fire chance penalty that comes with IFHE, resulting in Mainz having an easier time setting fires on enemy warships when using that skill. A disadvantage to Mainz’s HE shells is a relatively low HE Alpha, resulting in her dpm being comparable to Chapayev.
The AP shells on Mainz compare a bit differently to other AP shells. While the HE shells offer a rather uninspiring damage output, the potential output of Mainz’s AP shells is outstanding. None of the Tier VIII light cruisers save for Bayard during the usage of Main Battery Reload Booster () can match the AP dpm of Mainz. In terms of penetration these shells are average, sitting right in between Cleveland and Bayard. What this means however is that these shells are not capable of landing citadel hits unless at short range, but they do deal tremendous amounts of damage should a target reveal its side.
A formidable main battery firing range of 17.5km ensures that Mainz is able to apply her damage even on some of the less favorable high tier maps, but her firing angles are rather limiting. Towards the bow a full broadside is possible at 38°, towards the rear only at 40°, meaning that Mainz is open to penetrations against her hull while firing broadsides. A high muzzle velocity results in good shell flight times in comparison to other 152mm armed ships at her tier.
Where Mainz offers a rather nasty sting is in terms of torpedo armament. Her torpedo batteries match that of Tier X cruiser Hindenburg with two quadruple launchers on each side of the ship. While the potential damage that such a salvo can deliver is in theory enough to destroy most ships in the game with one broadside, the range is just as short as it is on the other heavy cruisers with only 6km range, limiting the usage.
While the Secondary battery also benefits from the 1/4 HE penetration rule, the 105mm guns are mostly useless due to the lacking range and lacking damage output. At best they will set a fire on a hostile vessel.
In terms of survivability Mainz sitson a similar level compared to her half sister Admiral Hipper. A large hitpool, far beyond that of other Tier VIII light cruisers, but also a large hull as well as a thin armor belt mean that while Mainz has the reserves to take hits, these are highly likely to deal damage. And unlike Prinz Eugen, Mainz has no Repair Party (). She also does not have the 27mm hull plating that her half sisters can offer, only her midship deck is 27mm thick while the upper belt and upper bow are only 25mm thick. This does make Mainz vulnerable against 380/381mm AP shells that can overmatch through large sections of her hull. The turtleback, while offering additional protection for the vital areas, does not prevent painful normal penetrations. Some protection can be gained from the icebreaker bow, which covers roughly half of her bow with a thickness of 40mm. However outside of close range encounters it is difficult to capitalize on this plating, and it cannot be relied on. What comes on top is that Mainz shares the rather fragile turrets of Nürnberg, making her main battery prone to incapacitations against HE shells and most AP shells.
The maneuverability of Mainz leaves something to be desired. The rudder shift is rather long, the top speed among the lowest and the turning circle is nothing to write home about. In combination with the lack of armor on her hull this means that Mainz will struggle to consistently and effectively avoid incoming damage at medium ranges.
The AA protection of Mainz is rather decent compared to her half sisters. She shares the same 105mm dual purpose guns, but also carries a large array of 37mm guns which will throw out 319 damage per second against aircraft, almost on the same level as Baltimore. While this can make Mainz a costly target to drop, it does not grant her immunity against aircraft however, even when applying additional AA improvements such as Defensive AA Fire () or captain skills.
One of Mainz’s major weaknesses is her surface detection. Even when fully investing into concealment she only reaches 12km, worse than any other Tier VIII light cruiser. This results in Mainz being unable to dictate the engagement, and should an opponent choose to keep her lit for the team to shoot at Mainz will struggle to evade this threat.
In regards to Mainz’s consumables she shares those of her half sister Admiral Hipper. Standard cruiser Damage Control Party (), the choice between the improved, German Hydroacoustic Search () or Defensive AA Fire () and a Catapult Fighter ().What all this combines into is a medium to long range specialist. Decent ballistics and consistent damage output mean that Mainz can engage targets at range where she can evade returning fire. Should the late game make it possible, getting into brawling range where the AP shells can be effectively applied as well as the devastating torpedo salvos. Depending on what is deemed more important – defending herself against air attacks or being able to spot torpedoes and ships – the decision between Defensive AA Fire and Hydroacoustic Search is up to the player.

- Turtleback armor scheme prevents citadel penetrations at close range
- Bad concealment for a cruiser
- Low top speed and sluggish rudder shift
- Unlike Prinz Eugen, Mainz has no access to Repair Party ()
- Inferior armor profile compared to Prinz Eugen and Admiral Hipper
- Torpedoes are short ranged

The Kriegsmarine in 1936 intended to follow up two further heavy cruisers after the three that were under construction. However, in order to not provoke the British it was decided to disguise these ships as light cruisers, by equipping them with an armament of twelve 150mm guns instead of eight 203mm guns, similar to how the Japanese disguised the Mogami class as light cruisers.
At a length of 212.5m and a width of 21.9m, with a draft ranging between 6.9 and 7.9m, these ships were to displace more than the earlier classes. The standard displacement was 13,581 tons, however at full load this would raise up to 19,533 tons. Crew complement was intended to be 1,409 men.
The main armament was to consist of four turrets, each housing three 150mm L/55 C/28 guns. With a maximum rate of fire of eight rounds per minute these guns would fire a 44.7-45.5kg heavy shell at ranges up to 23km. The secondary armament was copied from the Admiral-Hipper class with twelve 105mm L/65 C/33 guns, distributed equally into six triaxially stabilized mountings. However, unlike the preceding classes, these were to be the more modern C/37 mountings. The initial AA outfit saw twelve 37mm C/30 guns in six twin mounts as well as eight 20mm automatic guns for close range defense. Twelve torpedo tubes in four mountings would provide the torpedo armament.
The machinery differed from the earlier cruisers. The number of boilers was reduced from twelve to nine, with three in each boiler room. Three Wagner-Deschimag turbine sets were to generate up to 132,000shp for a maximum speed of 32kn. Furthermore, the propulsion was redesigned in the hopes of extending the cruising range. The intended cruising range was to be 6,100nm at a speed of 15kn.
The armor was not changed compared to the Admiral-Hipper class. The main belt, inclined by 12.5°, had a thickness of 80mm and covered the entire length between the barbettes of A- and D-turret. Behind it followed a 30mm turtleback, with the thickness of the main armored deck being identical except for a few spaces above the magazines which were reinforced to 40mm thickness. The main belt was extended towards the bow, however it was thinner with 40mm which eventually was reduced further to 20mm at the bow. Likewise the belt extended towards the aft end of the ship, covering the steering gears with a thickness of 70mm. The barbettes for the main armament were protected by 80mm of armor. The protection of the turrets can only be estimated but they would most likely enjoy relatively heavy protection as the 150mm triple turrets were designed to match the 203mm twin turrets in both weight and barbette diameter. The conning tower had up to 150mm armor.
Aviation facilities included two catapults and a hangar for a total aircraft capacity of three floatplanes.
While two ships of this class, cruiser K and cruiser L, Seydlitz and Lützow respectively, were laid down, in both cases it was decided to arm them with 203mm guns before the 150mm armament had a chance to be installed. Thus both received the heavy cruiser armament from the get-go, although four 150mm triple turrets would remain under construction until 1941, however at low priority.
- The in-game ship carries the same turrets and guns from the light cruiser Nürnberg. However, the Kriegsmarine intended to develop new turrets that were to match the weight and barbette diameter of the larger 203mm twin, using the newer 150mm L/55 C/28 gun, not the older 150mm L/60 C/25 one. Nürnberg’s turrets as they are are more than 100 tons too light.
- The turtleback was identical in thickness to the Admiral-Hipper class, with a thickness of 30mm. In-game Mainz has a 40mm turtleback. Furthermore, the 40mm belt extension thins down at the bow to half its thickness. This is absent on the in-game model.
- The superstructure on the last two ships of the Admiral-Hipper class underwent a redesign. Initially it was intended to carry two catapults at the rear with one in front of the main mast and one behind. This was revised to one catapult, and there was a significant redesign of the forward superstructure that made it more akin to that on the Bismarck-class. The in-game model shows only one catapult while having the non revised forward superstructure.
- Mainz carries the 105mm dp guns in the older C/31 mountings, when the design saw them to be mounted in the newer C/37 mountings.
- The design called for 12 torpedo tubes in four triple launchers, not 16 torpedo tubes in four quadruple launchers.
- Mainz carries seven target selectors for the heavy AA armament, while at the same time only having four AA fire directors which could receive the orders from these selectors.
- The Admiral-Hipper class carried eight sub-caliber 88mm guns which could be inserted into the main guns in order to prevent barrel wear during gunnery exercises. When not in use these would be stored on deck in long cylindrical boxes. Mainz also carries these eight boxes, yet has twelve main guns.
