Aki SE 25 is the Legendary Japanese airstrike battleship. Her right-trigger fires a torpedo-bomber airstrike in place of shipborne torpedoes: the planes drop a spread of aerial torpedoes on the marked lane, a damage source that does not need line of sight on top of her main battery. Standout traits: best torpedo belt percent in Legendary BBs (55) and best armor plate in Legendary BBs (560 mm).
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.
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.
Right-trigger fires a bomber line in place of torpedoes. Rewards behind-cover positioning with the cap in range.
55.0% torpedo damage reduction, best of Legendary BBs.
560.0 mm max plate, best of Legendary BBs.
77.0 mm AP arming threshold, bottom decile of Legendary BBs. Over-pens thin plates; the trade-off pays off when most targets are battleship belt armor.

Not standouts for Aki SE 25 -- here's where she sits on every other ranked stat in the cohort. Stats tagged NORM are tied across more than half the cohort, so the value is the cohort default rather than a standout.

Covers AA-only mounts plus dual-purpose secondaries (Bismarck 105mm, USN 5"/38 cruiser secondaries) and dual-purpose main batteries (Sumner-class 5"/38, Akizuki-line 100mm). Formula validated against in-game captures on California, Sumner, Manfred von Richthofen, Dante Alighieri (exact) and within +/-17% on the remaining verified ships. Flak is NOT included: flak stops triggering once planes are inside 2.5 km, and its avoidable burst damage is shown separately in the Flak bursts section.Longest-reaching aura across AA-only + dual-purpose auras.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.Max dispersion = range (km) × 57 + 30. Each dispersion type sets its own slope; this is not a percentage applied to a standard baseline.5 km × 57 + 30 = 315 m.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).

Shells whose pen falls under a plate's armor thickness shatter for 0 hull damage though fire chance still applies. Best on this ship: 26 mm from the 155 mm family.Hull HP 102,300, distributed across 5 hull zones, each with its own plate thicknesses, saturation cap, and pen thresholds.

Overmatched by 7 guns here: Incomparable SE 25IncomparableYamato and 4 more. Angling still helps against the rest.
Citadels come from a flat broadside at close range; held past ~30° of angle, AP shatters or bounces.
Superstructure and extremities take HE pens and AP overpens from nearly any gun: steady chip damage. Fire resistance 40%, fires burn 60s. Range-by-range in the Compare tool →

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.
