Player Opinion

Performance

Gustav-Julius Maerker is a Tier VIII German destroyer armed with 150mm guns, and the point where the German alternative DD line truly branches off. In terms of pure size, the Maerker is absolutely massive, with a length and tonnage approaching that of a small light cruiser. This size defines the Maerker and the way she plays compared to her peers.

The Maerker's size makes her ungainly and hard to hide -- her detection of 7.76km is sixth-worst in tier, and her maneuverability is among the worst, with the worst turning radius at 760m and the second-worst rudder shift at 5.5s, only beating the Akizuki's concrete rudder by a tenth of a second. Dodging shots and lurking around the fringes of other ships' detection are not high on the Maerker's list. Her top speed of 36 knots is respectable but not outstanding compared to her destroyer competition, and while her anti-aircraft DPS is good at medium and short range, she lacks any long-range flak capability, restricting her actual AA range to 3.5km -- though as this is less than her air detectability at 4.36km, there is no reason to turn it off compared to other destroyers.

On the flip side, however, the Maerker's size gives her the largest health pool of any Tier 8 destroyer by far, with over 2000 points over the nearest competition and 8000 over her most fragile competitor in the Oland. The Maerker's side plating is also thick for a destroyer, allowing her to better resist enemy HE fire and out-muscle enemy destroyers. Furthermore, while her innate stealth is not great, the Maerker's Smoke Generator is better than that of her cousin Z-23, on par for the tier with the Japanese and Soviet smokescreens.

Maerker is the rare destroyer that wants to emphasize its AP, thanks to her six-inch guns. While her HE is the worst among destroyers in the entire tier both in single-salvo damage and sustained DPM, her AP is the best at a terrifying 18,000 damage per salvo, and its penetration is comparable to that of the British Edinburgh (though without Edinburgh's hair-trigger fuse time). Its slow rate of reload and glacial turret traverse does make using this difficult, but are offset by extremely high accuracy and a near best-in-tier shell speed that make landing what shots she gets off easier and more reliable.

This combination of factors allows her to use AP on destroyers with reasonable results. However, it also allows her to threaten enemy light cruisers, whose lightly armored citadels she can demolish in short order.

Finally, the Maerker's torpedo armament is difficult to use but potent if mastered. At 50 knots, her torpedoes are the slowest in the entire tier, even more than the Italians or the Kidd's. However, she carries eight of them in a Mahan-style split battery with one quad centerline launcher and two wing single launchers. In addition, her torpedo range of 12km is among the best in the tier, and the high damage of the individual torpedoes combined with a reasonable reload speed of 90 seconds means her overall fish DPS is very competitive. As such, the Maerker can keep up sustained torpedo fire from a distance, wheeling around or swerving to deliver follow-up shots from her split wing launchers.

As a result, the G.J. Maerker is an odd mid-point between destroyers and cruisers, suffering from not having the true strengths of either but being able to reasonably engage both. Her poor maneuverability, mediocre detectability, lack of Hydroacoustic Search, slow reload, and terrible HE shells makes engaging other destroyers at close quarters a bad idea; however, her high health pool, tough sides, and highly accurate guns mean she can hit them reliably while taking less damage from their return fire at range. Against cruisers, she lacks their health pool, armor, or DPS; however, she can outstealth them, outmaneuver them (at least in terms of rudder shift and acceleration), and pose a serious threat with her AP to their citadels while presenting none in return.

The Maerker is, on the whole, a standoffish ship, and one that struggles at traditional DD roles such as forward scouting and contesting caps. It wants time and distance to bring its strengths to bear; if given them, however, it can put out reliable and significant damage.

Pros:

• Large health pool at tier VIII compared to other DDs
• Tough side plating
• AP shell have high damage
• Improved AA armament
• Torpedoes have long range
• Smoke Generator’s smoke lasts longer than Z-23’s

Cons:

• Lack of Hydroacoustic Search
• Slow torpedoes
• Near-worst maneuverability for tier
• High detectability for tier
• Horrible HE shells

Research

Researchable upgrades for Gustav-Julius Maerker is as follows:

• Hull: Upgrade to Hull (B) for a larger health pool, improved maneuverability, and especially better AA. Research of this module unlocks progress toward IX Felix Schultz.
• Gun Fire Control System: Upgrade to FKS Typ 8 Mod.2 for an extra 10% range on the main battery.

Optimal Configuration

Recommended upgrades for Gustav-Julius Maerker:

• Slot 1: Main Armaments Modification 1
• Slot 2: Engine Room Protection
• Slot 3: Aiming Systems Modification 1
• Slot 4: Propulsion Modification 1
• Slot 5: Concealment System Modification 1  *

Because of the lack of hydro-acoustic search capability, and if primarily firing at range, a Torpedo Lookout System might prove more useful. Also consider Steering Gears Modification 2 .

History

The G.J. Maerker is an example of the Type 1937J, a destroyer concept drafted by the Kriegsmarine in 1937 as one of five project studies for an "ocean-going destroyer" -- a long-range destroyer capable of operations in the tropics and escorting oceanic raiding groups. The Type 1937s were originally designed with six 127mm guns due to the negative experience with the 150mm on the Type 1934, and due to the desire to avoid a "cruiser-destroyer" design, whose nebulous size and role would make it less effective than a dedicated version of either. Nevertheless, the J-variant with five 150mm was nevertheless concluded to be the most promising design of the five Type 1937s, and was continued in design.

However, the range and speed requirements proved beyond the ability of Germany's resurrected naval design boards to achieve. The 1937J's gigantic size for a destroyer (nearly twice the displacement of a Fletcher) was still not enough to achieve 4,450 nm range and a top speed of 36 knots. When it was concluded that the design would need to reduce the armament to reach the range and speed marks, Admiral Raeder ordered work on the design stopped. Nonetheless, work from the design would contribute to the development of the Type 1938 destroyers of Plan Z, and from them, the Spähkreuzer.

Design

The G.J. Maerker is shown in-game as the initial concept for the Type 1937J, either realized with more advanced technology or possibly with reduced range. At a loaded tonnage of 5,100t, she is by far the largest destroyer at tier 8, entering into the neighborhood of some very small light cruiser designs such as the British Arethusa-class.
