Overview

Ibuki is a Tier VIII Japanese IJN cruiser with the improved AP fuse: her AP shells arm at 60% of the standard armor threshold, so they citadel cruisers that would over-pen a normal CA round. Lean on AP into broadsides and short-angled cruisers - HE-spamming this hull leaves the cohort's best damage tool on the rack. Sonar (4.9 km on ships and 3.5 km on torpedoes, 96 s active, 180 s reload, long uptime) lights up DDs and torpedoes inside its bubble, which lets her contest the cap edge without taking the spotting cycle.

Positioning

Sit 12-15 km from a contested cap where an island shadows you from the opposite battleship line. Hydro (4.9 km on ships, 3.5 km on torpedoes) lights up DDs and incoming torpedoes inside its bubble, so you can push the cap edge from cover without taking the spotting cycle; prefer cover positions over open-water flanks.

Potato Avoidance

Open-water broadside trading

Her 203mm shells citadel cruisers on the wrong frame, and her 39,000-HP hull does not recover from a punished salvo. Pick rotations and angles deliberately; the chip-damage role pays better than the trade-blow role on a cruiser of this profile.

Signature Traits

Improved AP fuse (IJN cruiser)

AP arms at 60% of the standard armor threshold (vs 0.9 default). Lets your AP pen broadsiding cruisers that would over-pen a normal CA, citadel hunts the cohort can't pull off, unique in T8 CAs.

Heavy torpedoes

20967.0 damage per torpedo, best of T8 CAs.

Fast torpedoes

67.0 kt torpedo speed, top decile of T8 CAs. Less reaction time for targets to dodge.

Nimble for the tonnage

10.27 hp per ton, top decile of T8 CAs. Engine punch outclasses the hull's mass, so the ship retains speed through sustained turns better than peers.

Thick stern plate

30.0 mm stern, top decile of T8 CAs.

Visible torps

1.7 km torpedo detect, worst of T8 CAs. Easy to dodge if targets are looking.

Acquisition

How to get Ibuki

Ibuki is available in the Combat Heavy Cruisers branch of the Japan Tech Tree for 25,000,000 credits after researching it in the branch. Known module upgrades cost up to 6,250,000 credits.

Magazine HP

The magazine is the module a detonation comes from. Penetrating hits to it raise the detonation chance from 1% toward 30% as its HP is worn down, so a larger magazine pool rides out citadel hits longer before a detonation becomes likely.

Per-family: 4×2 100 mm (4/side) × 60/2.86 × 1700 = 142,657. Assumes every shell hits (real hit rate is lower; the Brawl matchup tool on the Compare page folds in dispersion + target armor).

Max HE alpha1700

Maximum HE damage per shell across secondary HE families. Best on this ship: 1700 from the 100 mm family.

Max HE fire chance6%

Maximum per-shell fire chance across secondary HE families (before target fire resistance is applied). Best on this ship: 6% from the 100 mm family.

Max HE pen17 mm

Maximum HE armor penetration across secondary HE families (caliber × 1/6 for most nations; 1/4 for German/UK BBs). Shells whose pen falls under a plate's armor thickness shatter for 0 hull damage though fire chance still applies. Best on this ship: 17 mm from the 100 mm family.

Hull HP 35,100 → 39,000 with hull upgrade, distributed across 5 hull zones, each with its own plate thicknesses, saturation cap, and pen thresholds. HP caps are the exact in-game values, not estimated.

Citadel	140 mm primary (range 27–140 mm)	≈ 165,500 (effectively no cap)	Citadel pen ×0.33 damageOver-pen: ×0.10 damage	Effectively no cap; citadel pool sits at ~165k HP on every ship. Damage is gated by pen/over-pen multipliers instead (×0.33 direct pen, ×0.10 over-pen).
Superstructure	6 mm primary (range 6–100 mm)	1,200 (3% of HP)	Any HE ≥16 mm pens at full damage	Any HE ≥16 mm pens at full damage. HE-spam target, and the section saturates fast (often only a few thousand HP).
Turret (module, per magazine)	separate HP pool, does not drain ship HP	19,500 magazine HP	Magazine detonation1–30% chance · below ~75% HP	Per-turret powder-magazine HP. Detonation chance scales from 1% (no mag damage) to 30% (full mag damage); this range is the in-game value. Detonation can't roll while the ship is above ~75% HP (the standard detonation-protection threshold, not a per-ship stat). Smaller magazines saturate to the 30% ceiling faster.
Secondary mount (100 mm mount)	separate HP pool, does not drain ship HP	800 per-mount HP	Destroyed at 0 HP	Per-mount HP for the heaviest secondary on this ship. A mount destroyed at 0 HP is out for the rest of the battle; DCP does not repair destroyed mounts. Smaller (lighter-caliber) secondaries typically share the same HP value.
AA mount (40 mm mount)	separate HP pool, does not drain ship HP	200 per-mount HP	Destroyed at 0 HP	Per-mount HP for the heaviest AA on this ship. An AA mount destroyed at 0 HP stops shooting down planes for the rest of the battle; DCP does not repair destroyed mounts. HE shells specifically target AA mounts since the small-caliber HP pool falls fast.
Rudder (module)	separate HP pool, does not drain ship HP	11,700 module HP	Incapacitated at 0 HP	When module HP reaches 0 the rudder locks at its current angle until DCP repairs it. Repair via Damage Control Party.

Saturation cap = HP a section can absorb before further damage to it is reduced (the "bow-tank" effect). Citadel pool is ~165k on every ship (effectively no cap); damage is gated by pen/over-pen multipliers instead. Superstructure saturates fast but HE always pens regardless of the plate thickness. Rudder (and other module HPs) are a separate pool from ship HP: damaging a module doesn't drain ship HP. Incapacitated modules like the rudder and engine are restored by DCP, but secondary and AA mounts destroyed at 0 HP stay out for the rest of the battle.

Maximum AP shell damage increased from 4,700 to 5,150.
