Z-23 — German Tier VIII destroyer.

Developed from the Leberecht Maass-class destroyers (Zerstörer 1936A type), this ship had larger dimensions and greater firepower compared to her prototype. She is equiped with 128 mm main gun mounts rather than her historical 150 mm armament, but retains the torpedo armament of her predecessor.

Player Opinion

Performance

A solid upgrade to Leberecht Maass, Tier VIII's Z-23 is similar in broad strokes but sees incremental improvements in several key areas. Most welcome is the ability to take the concealment upgrade in the new upgrade slot, allowing her to reach a detection range of 6.2 km when combined with camouflage and the captain skill; still worse than most other destroyers, but at least closer to competitive. A slight downgrade in acceleration, rudder shift, and turning circle is compensated for by a meaty helping of 2,000 additional hit points.

In her stock configuration, Z-23 has exactly the same guns as Maass, but loses a gun. However, upon upgrading to the N-Hull Z-23 exchanges her forward single gun mount for a twin turret, bringing her gun count up to five guns.

Finally, the upgraded torpedoes pick up an extra kilometer of range, improving their flexibility. The 1-knot increase in speed is small but can only help as well.

All in all, like her predecessors Z-23 may not quite have the finesse of American or Japanese destroyers, but her durability, Hydroacoustic Search , and balanced gun and torpedo armaments allow her to adapt to almost any circumstance.

Pros:

• 128mm main battery guns have a very fast rate of fire.
• Main battery has increased HE penetration, making them more consistent
• Can deliver torpedo strikes from beyond her detection range.
• Has decent speed for a Tier VIII destroyer.
• Has access to Hydroacoustic Search .
• High amount of hit points for a Tier VIII destroyer, second only to Akizuki.

Cons:

• Relatively large detection range compared to other Tier VIII destroyers.
• Main battery turrets have a somewhat slow turret traverse speed.
• Mediocre AA.
• Very short smokescreen duration limits offensive smoking ability.

Research

Upgrade the hull first for a massive increase in survivability. Next, the upgraded torpedoes are more comfortable to use. Take the gun range last.

Optimal Configuration

Upgrades

The recommended upgrades for Z-23 are as follows:

• 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 

If available, captains are encouraged to install Hydroacoustic Search Modification 1 in Upgrade Slot 2 in order to extend Z-23’s Hydroacoustic Search  duration to 115 seconds.

Z-23 equips the following consumables:

Signals

The choice of which Signal Flags to mount will confer to the individual preference of each captain, and are subject to great variation, although there are certain flags which suit Destroyer game play better. Captains should mount India Yankee to decrease time to extinguish fires, mount November Foxtrot to decrease reload time of consumables, and mount Sierra Mike to increase the ship's maximum speed. To make their torpedoes more potent, captains should mount Juliet Whisky Unaone to increase chance of causing flooding and Juliet Charlie to mitigate risk to magazine detonation from mounting the former flag. If captains wish to buff their primary artillery, they are encouraged to mount Victor Lima + India X-ray to increase fire chance to HE shells.

History

Design

The destroyers of the Zerstörer 1936A class were the last class of destroyers designed by Germany before the outbreak of World War II. They were slightly larger than the preceding 1936 class, and were designed to be more stable in the seas. The hull was reinforced, and a bulge was installed at the bow to improve seaworthiness. The latter was eventually removed, however, as it proved to have negative side effects on the bow. A double rudder allowed better maneuverability than on the 1934 or 1936 classes.

The result was a 127 meter long and 12 meter wide hull with a draft of up to 4.65m. The displacement ranged between 2,600 and 3,700 tons depending on the loadout, and her engines — with a combined 70,000 shaft horsepower — would allow for a speed of 36 knots (during speed trials, speeds up to 38.5 knots were achieved). The fuel capacity gave these ships a cruising range of up to 2,500 nautical miles. The crew for a single vessel consisted of 11 officers and 320 men.

What made the 1936A class stand out from other destroyers of the era was their main battery armament. The 15cm L/48 was gun was unique to Germany, and the largest main battery rifle to be mounted on a destroyer to date. They were initially tested on the 1934-class destroyer Z-8 Bruno Heinemann, these guns were meant to counter new French and British destroyers, as well as allowing the 1936A class ships to serve as scout units and to compensate for the continual shortage of light cruisers and scouting units. There were two mountings available on the 1934A class, a single mount and a twin turret. Other than the number of guns in these mountings, they also differed in terms of gun elevations: the single mounting allowed for 30° elevations, whereas the twin turret could elevate up to 65°. Each ship of the Z-23 class was slated to receive one twin-barreled mount on the bow and three single-barreled mounts at the stern of the ship, with the sternmost two being superfiring and the central turret facing forward. The only exception for this layout was Z-28, which was used as a fleet command vessel and instead mounted four single mounts in two superfiring pairs, one at the bow and one at the aft. The Torpedo armament did not change from the 1934 series destroyers, with two quadruple 533mm torpedo tubes, and the initial anti-aircraft armament consisted of two twin 37mm Flakzwilling 30's and five single barreled 20mm FlaK 38's.

Availability issues with the 15cm twin turret meant that the first few vessels built only received four 15cm guns in single mountings. However, even the lighter armament showed that the bow was insufficiently designed and that the ships took a tremendous amount of water over the bow in the commonly rough seas of the northern Atlantic. When the twin turret was eventually installed in 1942 the issues with these guns became more noticeable. With the twin turret weighting more than four times that of a single mount, the fore ship was even more prone to being wet. As the turret was not properly designed to be waterproof the electrical systems within would often fail in heavy seas and the fixed ammunition meant that a lot of physical effort was required by the gun crews to reload the gun, which would hamper the ability to maintain a high rate of fire during combat.

With the threat from aircraft rising throughout the war, it was deemed as necessary to increase the anti-air-armament of all destroyers, resulting in the so-called “Barbara-program” which added additional AA guns for almost all ships in 1944. The proposed changes for the 1936A class ships were the removal of a 15cm single mount, and a completely new AA armament of twelve 37mm M42 and eighteen 20mm FlaK 38 guns, with the addition of 8.6cm AA rockets in four single launchers.

In-game historical inaccuracies

• Z-23 never carried 128mm guns, making her entire in-game main armament inaccurate.
• Neither Z-23 nor any of her sister ships had an AA gun platform around the forward funnel.
• The "Barbara-refit" that some of Z-23's sisterships received removed one of the main guns for additional 37mm weaponry. Z-23 in game keeps all of her guns, yet gets an increased 37mm battery.
