Indiana is best treated as crossfire creation and heavy salvo punishment. Take an angle that threatens broadsides while leaving room to turn out before the flank collapses.
Take an angle that threatens broadsides while leaving room to turn out before the flank collapses.
Reposition early when the enemy stops giving you useful shots.
this ship is not a regular Tech Tree unlock. Acquisition path: Premium/Event.
Start with the standard battleship priorities: survivability, concealment or positioning control where relevant, and enough reload/accuracy pressure to keep the ship useful all match.

Numbers the spec table cannot show directly: alpha-strike math, DPM, dispersion, AP penetration. Click the formula chip on any row to reveal how it is calculated.
Shell grouping (sigma); shown in-game as Shell Grouping.Horizontal dispersion ellipse width at max range, from the verified WoWS dispersion model: $\sigma_H = \left(\dfrac{R}{30}\cdot\dfrac{\text{idealRadius}-\text{minRadius}}{\text{idealDistance}} + \text{minRadius}\right)\cdot 30$ $= \left(\dfrac{17172}{30}\cdot\dfrac{12-2}{1000} + 2\right)\cdot 30 = 231.7\,\text{m}$Vertical dispersion ellipse height at max range: $\sigma_V = \sigma_H \cdot \text{radiusOnMax}$ $= 231.7 \cdot 0.6 = 139\,\text{m}$50%-hit horizontal radius: $\sigma_{H,50} = \sigma_H \cdot \text{GetHalfHitsRatio}(\sigma)$ $= 231.7 \cdot 0.344\;(\sigma = 1.8) = 79.7\,\text{m}$50%-hit vertical radius: $\sigma_{V,50} = \sigma_V \cdot \text{GetHalfHitsRatio}(\sigma)$ $= 139 \cdot 0.344\;(\sigma = 1.8) = 47.8\,\text{m}$Canonical community AP formula (jcw780/wows_shell), evaluated at muzzle velocity: $P = 10^{-7}\cdot K \cdot m^{0.69} \cdot d^{-1.07} \cdot v_0^{1.38}$ $= 10^{-7}\cdot 2598 \cdot 1225^{0.69} \cdot 0.406^{-1.07} \cdot 701^{1.38} = 778.8\,\text{mm}$. Matches the in-game spec card.Same formula at the ship's max firing range (21.5 km), where the shell has slowed to 467.4 m/s: $P = 10^{-7}\cdot 2598 \cdot 1225^{0.69} \cdot 0.406^{-1.07} \cdot 467.4^{1.38} = 445.1\,\text{mm}$.68 mm ≈ 406 mm caliber / 6 (standard HE penetration ratio).floor(406 mm caliber / 14.3) = 28 mm (AP auto-penetrates plating this thick or less).AP shell over-penetration splash radius; scales with shell mass. Wickes 102mm = 3, standard 152mm CL ~ 20, Iowa 406mm ~ 270, Yamato 460mm = 400, Incomparable 650mm = 550 (max). Larger value = bigger splash damage area when AP over-pens.All 9 barrels bear on the broadside.180 degrees / 4.5 deg/s traverse speed = 40 s.5,700 HE damage x 9 broadside guns = 51,300.13,100 AP damage x 9 broadside guns = 117,900.51,300 HE full-salvo alpha x 60 / 28 s base reload = 109,929.117,900 AP full-salvo alpha x 60 / 28 s base reload = 252,643.51,300 HE full-salvo alpha x 60 / 25.2 s installed reload (Main Battery Mod. 3 = -10%) = 122,143.117,900 AP full-salvo alpha x 60 / 25.2 s installed reload (Main Battery Mod. 3 = -10%) = 280,714.9 broadside guns x 60 / 28 s base reload = 19.3.9 broadside guns x 60 / 25.2 s installed Artillery reload = 21.4.9 HE shells x 60 / 28 s reload x 36% fire chance = 6.94.9 HE shells x 60 / 25.2 s installed reload x 36% fire chance = 7.71.Sum across every AA aura on this ship of (aura.continuous_damage x 3.5 x aura.hit_probability). Here: (90×3.5×0.75) + (106×3.5×0.7) + (50×3.5×0.75) = 627. 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.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) × 27 + 30. Each dispersion type sets its own slope; this is not a percentage applied to a standard baseline.7 km × 27 + 30 = 219 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). Per-family: 10×2 127 mm (10/side) × 60/4.5 × 2000 = 266,667. Assumes every shell hits (real hit rate is lower; the Brawl matchup tool on the Compare page folds in dispersion + target armor).Maximum HE damage per shell across secondary HE families. Best on this ship: 2000 from the 127 mm family.Maximum per-shell fire chance across secondary HE families (before target fire resistance is applied). Best on this ship: 5% from the 127 mm family.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: 25 mm from the 127 mm family.Hull HP 64,700, 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.
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 ballistics tool →
| Section | Plates | HP cap | Threats | Tactic |

| Stern | 32 mm primary (range 32–343 mm) | 4,800 (7% of HP) | Overmatched by 460mm+ (Aki, Musashi)Angle bounces 410mm32 mm: HE pens from 203mm+ | Mirror of bow. Same fast saturation. |
| Citadel | 310 mm primary (range 38–274 mm) | ≈ 165,500 (effectively no cap) | Citadel pen: full damageOver-pen: ×0.10 damage | Effectively no cap; citadel pool sits at ~165k HP on every ship. An AP citadel penetration deals the shell's full damage, the biggest single hit available; only over-penetrations are damped, to ×0.10. |
| Superstructure | 6 mm primary (range 6–406 mm) | 3,700 (6% 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). |
| Secondary mount (127 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 | 19,400 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.
