Overview

Ise is the Tier VI Japanese airstrike battleship. Her right-trigger fires a line of dive bombers in place of torpedoes, which gives her a damage source that does not need line of sight on top of her main battery. Standout traits: best stern plate in T6 BBs (224 mm) and best high-arc HE shells in T6 BBs (33.6°).

Positioning

Park 14-17 km from a contested cap with island cover within one rotation of your bow. The airstrike line wants to cross the cap and the predictable retreat lane, both of which favor positions a little further back than a brawler would take. Open-water lanes are pure downside; you do not need line of sight to score with the airstrike, so cover is free upside.

Potato Avoidance

Launching airstrikes at maneuvering targets

The squadron's travel time is long enough that a healthy DD or cruiser with engine boost simply turns out of the cone. Reserve strikes for capping destroyers, island-huggers, and anyone already tying up with a teammate.

Signature Traits

Airstrike alt-armament

Right-trigger fires a bomber line in place of torpedoes. Rewards behind-cover positioning with the cap in range.

Acquisition

How to get Ise

Ise is available in the Aviation Battleships branch of the Japan Tech Tree for 9,000,000 credits after researching it in the branch. Known module upgrades cost up to 2,250,000 credits. Official source cards below may also show its temporary Early Access window before it became a normal Tech Tree unlock. Container chances are shown as the listed odds of receiving this exact ship, dividing grouped ship-pool odds across the resolved ships and including nested container paths when a crate can drop another crate.

Main battery formulas

Shell Grouping (σ)2
Max Horiz Disp191.5 m
Horizontal dispersion ellipse width at max range, from the verified WoWS dispersion model: $\sigma_H = \left(\dfrac{R}{30}\cdot\dfrac{\text{idealRadius}-\text{minRadius}}{\text{idealDistance}} + \text{minRadius}\right)\cdot 30$ $= \left(\dfrac{14925}{30}\cdot\dfrac{10-2.8}{1000} + 2.8\right)\cdot 30 = 191.5\,\text{m}$
Shell scatter width @ 10 km156 m
How wide your shells scatter at 10 km, from the same dispersion model as the max-range figure above. Picking a fixed range makes this number directly comparable from ship to ship: max-range dispersion makes a longer-range gun look worse even when it's tighter at any common range. The interactive Dispersion tab on the Charts card plots the full curve from 0 to max range.
Max Vert Disp153.2 m
Vertical dispersion ellipse height at max range: $\sigma_V = \sigma_H \cdot \text{radiusOnMax}$ $= 191.5 \cdot 0.8 = 153.2\,\text{m}$

How tall the same scatter ellipse is at 10 km. Comparable from ship to ship for the same reason as the width value above.

Same formula at the ship's max firing range (20.5 km), where the shell has slowed to 457.3 m/s: $P = 10^{-7}\cdot 2657 \cdot 673.5^{0.69} \cdot 0.356^{-1.07} \cdot 457.3^{1.38} = 336.5\,\text{mm}$.

AA threat index1707
SUM over AA auras of (aura DPS x aura range km). A plane crossing the AA bubble is exposed to each aura for a time proportional to that aura's range, so long-reach DPS is worth more than the same DPS in a short bubble. Units: DPS*km; used to rank overall AA threat across the cohort.

Secondary battery firepower

Secondary DPM (per side)168,000
Sum across all secondary families of (per-side barrels × 60 / reload_s × alpha), where per-side barrels = mounts × barrels-per-mount / 2 (the guns that bear on one broadside target). Per-family: 8×2 127 mm (8/side) × 60/6 × 2100 = 168,000. Assumes every shell hits (real hit rate is lower; the Brawl matchup tool on the Compare page folds in dispersion + target armor).
Max HE alpha2100
Maximum HE damage per shell across secondary HE families. Best on this ship: 2100 from the 127 mm family.
Max HE fire chance8%
Maximum per-shell fire chance across secondary HE families (before target fire resistance is applied). Best on this ship: 8% from the 127 mm family.
Max HE pen21 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: 21 mm from the 127 mm family.

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 (127 mm mount)separate HP pool, does not drain ship HP800 per-mount HPDestroyed at 0 HPPer-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 (120 mm mount)separate HP pool, does not drain ship HP200 per-mount HPDestroyed at 0 HPPer-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 HP18,800 module HPIncapacitated at 0 HPWhen 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.
