Special

Iwaki Alpha — Japanese special premium Tier IV cruiser.

An advanced design of the Tenryu-class cruiser. The ship's displacement exceeded that of her predecessor, which allowed for a reinforced artillery armament and more powerful propulsion. At the project design stage, the cruiser was faster than all existing cruisers and many destroyers.

Iwaki Alpha was awarded to testers in March 2015 who had played 100 matches during the Closed Alpha period. The ship has not been made available since.

Player Opinion

Performance

Warning: The data presented in the AA Defense sidebar section may be incorrect.
Refer to the in-game Port screens for more useful data.

Iwaki Alpha is best treated as a destroyer (DD) that is the size of a cruiser. She has a smoke generator like a DD, and two triple racks of 610mm torpedoes with massive hitting power. With its light armor and good maneuverability this ship can wolf pack it with the best of them. When played like a torpedo destroyer this ship can work wonders.

The biggest drawback is Iwaki Alpha's cruiser sized hull with a deck-to-keel citadel. Stay undetected as much as you can.

Pros:

  • Fast and maneuverable.
  • The guns can be made very accurate indeed.
  • Hard hitting, stealthy, long-range torpedoes (10 km) that give her the ability to launch from outside detection range.
  • Two triple center-line racks for a full six torpedo salvo.
  • Equipped with the smoke generator and hydroacoustic search consumables.
  • Has access to four upgrade module slots (compared to the usual two).

Cons:

  • Thin armor.
  • Prone to citadel hits and incapacitation of modules.
  • Generally lousy guns (DPM, range, ballistics).
  • Poor forward torpedo firing arcs.
  • Lacks secondary artillery armament.
  • Weak anti-aircraft guns (3.1 km) with no long-range capability.

Research

As a premium ship, Iwaki Alpha doesn't have any modules to research.

Optimal Configuration

The following information is provided for players who wish to create a permanent captain for the ship. Those players who are retraining captains or using the ship to gain extra experience for a captain should consult the page relevant to the ship to which the captain will be assigned.

Upgrades

Iwaki Alpha can equip the legendary Aiming Systems Modification 0 : +20% main battery traverse speed. / -40% main battery dispersion. / +20% torpedo tubes traverse speed. / +20% secondary battery firing range. / -40% secondary battery dispersion. — one of only three ships that can do so[1] — for large buffs to all main armament. Similar to Arkansas Beta, Iwaki Alpha has access to upgrade slots 3 and 4 that other ships of her tier do not.

The recommended upgrades for Iwaki Alpha are as follows:

Combining Aiming Systems Mods 0 and 1 makes Iwaki Alpha the most accurate (smallest dispersion ellipse) ship in the game.

Commander Skills

Consumables

Iwaki Alpha equips the following consumables:

Camouflage

As a premium ship, Iwaki Alpha comes with Default permanent camouflage and a set of permanent combat bonuses.

Signals

Iwaki Alpha is reasonably fast, so Sierra Mike (+5% to the ship's maximum speed.) may be useful to the player. Victor Lima (+1% chance of causing a fire for bombs and shells with a caliber above 160mm / +0.5% chance of causing a fire for bombs and shells with a caliber below 160mm. / +4% chance of causing flooding.) and India X-Ray (+1% chance of causing a fire for bombs and shells with a caliber above 160mm. / +0.5% chance of causing a fire for bombs and shells with a caliber below 160mm. / +5% to the risk of your ship's magazine detonating.) may be used to increase the fire chance of main battery high explosive ammunition by 1%. Juliet Whiskey Unaone (+15% chance of causing flooding. / +5% to the risk of your ship's magazine detonating.) will increase torpedo efficiency by increasing the chance to cause flooding.


Note: Use of the Juliet Charlie signal makes detonation impossible.
