Overview

BA Tirpitz is a Tier VII German fire-starter battleship: her improved-penetration HE farms fires and chips angled targets her AP cannot crack, so the kit is sustained HE pressure from range rather than bow-in trading. HE pen sits at the 1/4 caliber ratio instead of the standard 1/6, so HE spam is a real damage option here. Standout traits: best magazine armor in T7 BBs (150 mm) and top-decile punch-through secondaries in T7 BBs (38 mm).

Positioning

Anchor a flank at 14-17 km where the team can rotate behind you. The HP pool lets you absorb focus that drains peer BBs out, but absorbing focus without trading is just wasted HP; pick salvo targets that exploit the angle others avoid.

Potato Avoidance

Sitting on Secondary Battery Reload Booster waiting for a perfect target

With 3 charges it is a cycle, not a finisher: every minute it spends full is a salvo you never fired. It comes back every 140 s, so press it early, press it often, and treat a charge bar that is never empty as damage you have not collected.

Signature Traits

Turtleback armor

Deck armor angled downward over the citadel, forming a roof outside it. Deflects shells arriving at a low angle up and away, so flat-trajectory fire from close range struggles to reach the citadel.

Improved HE penetration

HE pen at the 1/4 caliber ratio instead of the standard 1/6. HE-spam is a real damage option here, not just a fire-starter, shared by 15/49 T7 BBs.

Heavy magazine armor ↗

150 mm magazine protection, best of T7 BBs. Shrugs off hits that knock peers' turrets out.

Punch-through secondaries ↗

38 mm best HE pen across secondary families, top decile of T7 BBs. Pens hull plates peers' secondaries shatter on.

Fast turret traverse ↗

6°/s turret traverse, top decile of T7 BBs. Tracks fast-rotating targets peers can't keep up with.

Short gun range ↗

16.5 km main battery reach, bottom decile of T7 BBs. Outranged by peers; close distance or lean on terrain.

Fire resistance

Does not reduce the damage a burning fire does per second: replay-measured burn ticks run at the full rate on every ship. By elimination it lowers how often hits set you on fire; ignition-rate replay data is consistent with that but too confounded by attacker mix to measure the reduction directly.

36.6%

Fire duration60 s

Fire damage

Each fire ticks 0.3% of max HP per second for the full 60 s, so one unattended fire burns 18% of the pool (13,050 HP on this ship). 4 fire points can burn at once. Verified against measured burn ticks in replay data.

0.3% of HP per second

Flood duration40 s

Flood damage

A flood ticks 0.5% of max HP per second for the 40 s duration, so one unattended flood costs 20% of the pool (14,500 HP on this ship). Verified against measured flood ticks in replay data.

0.5% of HP per second

Torp Reduction

Reduces torpedo hit damage. Replay data shows no effect on floods: flood ticks run at the full rate and flood frequency does not decline with protection.

22%

Magazine HP

Per-turret powder-magazine HP, a separate pool from the ship's. Penetrating hits wear it down and the turret is likelier to be knocked out as it falls, so a larger pool keeps the guns firing through punishment that silences a peer's.

34,700

Steering gear HP

Durability of the steering gears. As this pool drops, hits are likelier to jam the rudder; unlike most modules the steering can be knocked out and repaired but is never permanently destroyed.

21,800

Effective HP

Base 72,500 HP plus everything Repair Party can restore: 0.6%/s x 28 s = 12,180 HP per charge, x3 charges = 36,540 HP. Ceiling, not a prediction: a charge only restores damage actually taken, and only the regeneratable share of it. Across 1,826 players in our replay corpus the median ship realized about half of this, mostly because half the charges go unspent — when Repair Party IS pressed it returns ~97% of the per-charge figure above.

Turret traverse arcs

How far each mount can train, in degrees to either side of the mount's own facing, read from in-game data. A rear turret with ±150° leaves a 60° blind wedge over the bow; one-sided arcs are wing mounts that cover a single side. The data does not say which way each mount faces, so the arcs are listed per mount without bow/stern angles.

4x ±145°

Guns to bear

How far off the bow (or stern) the ship must angle before every main turret can fire: the widest blind wedge among the rear-facing (or forward-facing) mounts, from each mount's trainable arc. Mount facing is inferred from turret stations and verified against known layouts, including Izumo's aft-facing forward turret.

Maximum simulated damage

Estimate of WG's in-game value; matches the in-game port screen within ±5%. Saturation: most targets only intersect one hull section, so the sim transfers ~1/3 of the warhead alpha (2/3 when the warhead blast >= 5000 and the burst reaches a second section). For this ship:

D_{sim} = α \cdot c = 38, 100 \cdot 0.333 = 12, 700

≈ 12,700

Maximum damage (ammunition)

The ammunition card's 'Maximum Damage' stat, exact: warhead alpha / 3 plus the blast addend. This is the per-torpedo number most references quote; the 'Maximum simulated damage' row above is WG's separate geometry-sim stat from the launcher spec panel.

13,700

Torpedo detectability1.3 km

Reaction time

How long a target has to dodge after your torpedo is spotted at its detectability range (lower means less warning):

t_{react} = \frac{1.3 km}{68 kt \times 2.6855} = 7.1 s

. The 2.6855 m/s-per-knot game-speed factor is calibrated from in-game measurement; the community's traditional 2.6 reads about 3% slower. Base value; commander torpedo-concealment skills lower it further. Community torpedo-reaction calculator by u/LorenDovah and u/The_ColorOutofSpace.

7.1 s

Flooding chance

Read straight from the game's own data: this torpedo carries a flooding-chance value of 2.27 per hit, shown as

2.27 \times 100 = 227 %

. Torpedo flood values above 100% are normal: in battle the base chance is scaled down by the target's torpedo protection (the Torp Reduction stat on its Survivability card) and any flood-resistance modifiers, so a value above 100% keeps flooding likely even through partial protection.

Bursts

Each ~2 s wave fires 2 quick salvos of 4 clouds ahead of the attacking squadron, plus 2 stray clouds farther out that appear off-beat between waves - up to 10 clouds per wave × 210 damage each. Planes that fly into a cloud take its damage; clouds dissipate before the next wave lands. Defensive AA Fire, where fitted, multiplies the salvo repeats within each wave.

Cloud damage

Damage a plane takes for flying into one flak cloud, before any reductions.

Cloud spawn chance

Each cloud in the pattern rolls this chance to spawn, so waves average fewer clouds than the maximum. Often called flak 'hit chance', but spawned clouds always damage planes that fly into them - the roll is on spawning.

75%

Wave rate

A flak wave spawns roughly every 2 s - timed frame-by-frame from gameplay footage and consistent across ships.

every ~2 s

Fired by

Flak keeps firing while at least one secondary battery mount is operational - even losing every other AA mount does not stop it.

Secondary battery

Flak zone

The activation band: flak fires while attacking planes are inside it. Clouds are placed ahead of the planes' path, so bursts can land short of 2.5 km or past 4.5 km - once planes get inside the band, new waves stop. AA range bonuses push the outer edge out; the 2.5 km inner edge does not move.

Traverse-to-turn ratio

How many degrees the turret can swing for each degree the hull turns. Turn rate

Shell scatter width @ 15 km213 m

Horizontal scatter at a fixed 15 km, from the same verified dispersion model - the long-range anchor. Only shown when the ship's guns reach 15 km.

Max Vert Disp136.7 m at 16.5 km

Vertical dispersion ellipse height at max range: $σ_{V} = σ_{H} \cdot radiusOnMax$ $= 227.8 \cdot 0.6 = 136.7 m$

Shell scatter height @ 10 km85.5 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. The height/width ratio is a piecewise-linear curve through three points from the ship's own dispersion data:  $radiusOnZero = 0.2$  at 0 m,  $radiusOnDelim = 0.5$  at  $delim \cdot R_{m a x} = 0.5 \cdot 16515 = 8258$  m, and  $radiusOnMax = 0.6$  at 16515 m. Above the kink:  $k = 0.5 + (0.6 - 0.5) \cdot \frac{10000 - 8258}{16515 - 8258} = 0.5211$ , so  $σ_{V} = σ_{H} \cdot k = 164 \cdot 0.5211 = 85.5 m$ .

Med Horiz Disp72 m at 16.5 km

50%-hit horizontal radius: $σ_{H, 50} = σ_{H} \cdot \frac{0.6}{σ}$ $= 227.8 \cdot \frac{0.6}{1.9} = 72 m$

Med Vert Disp43.2 m at 16.5 km

50%-hit vertical radius: $σ_{V, 50} = σ_{V} \cdot \frac{0.6}{σ}$ $= 136.7 \cdot \frac{0.6}{1.9} = 43.2 m$

AP Pen Close729.4 mm point-blank

Canonical community AP formula (jcw780/wows_shell), evaluated at muzzle velocity:  $P = 10^{- 7} \cdot K \cdot m^{0.69} \cdot d^{- 1.07} \cdot v_{0}^{1.38}$   $= 10^{- 7} \cdot 2450 \cdot 800^{0.69} \cdot {0.38}^{- 1.07} \cdot 820^{1.38} = 729.4 mm$ . Matches the in-game spec card.

AP Pen Far436.8 mm at 16.5 km

Same formula at the ship's max firing range (16.5 km), where the shell has slowed to 565.5 m/s:  $P = 10^{- 7} \cdot 2450 \cdot 800^{0.69} \cdot {0.38}^{- 1.07} \cdot {565.5}^{1.38} = 436.8 mm$ .

AP pen 5 km618 mm

AP penetration at a fixed 5 km, read off the same PC-validated ballistic curve as AP Pen Close/Far: the shell's impact velocity at that range fed through the canonical community AP formula  $P = 10^{- 7} \cdot K \cdot m^{0.69} \cdot d^{- 1.07} \cdot v^{1.38}$ . Fixed anchors make ships directly comparable at the same fighting distance; the Charts card plots the full curve.

AP pen 10 km527 mm

AP penetration at a fixed 10 km, read off the same PC-validated ballistic curve as AP Pen Close/Far: the shell's impact velocity at that range fed through the canonical community AP formula  $P = 10^{- 7} \cdot K \cdot m^{0.69} \cdot d^{- 1.07} \cdot v^{1.38}$ . Fixed anchors make ships directly comparable at the same fighting distance; the Charts card plots the full curve.

AP pen 15 km455 mm

AP penetration at a fixed 15 km, read off the same PC-validated ballistic curve as AP Pen Close/Far: the shell's impact velocity at that range fed through the canonical community AP formula  $P = 10^{- 7} \cdot K \cdot m^{0.69} \cdot d^{- 1.07} \cdot v^{1.38}$ . Fixed anchors make ships directly comparable at the same fighting distance; the Charts card plots the full curve.

AP flight time @ 10 km4.99 s

How long an AP shell takes to reach a target at a fixed 10 km, from the same numerically integrated trajectory the Charts card plots. The shell slows under quadratic air drag,  $a_{drag} = k ρ v^{2}$ , where  $ρ$  is air density from a standard-atmosphere profile and  $k$  bundles the shell's drag coefficient, caliber and mass:  $k = \frac{π C_{d} d^{2}}{8 m} = \frac{π \cdot 0.2763 \cdot {0.38}^{2}}{8 \cdot 800} = 1.96 \times 10^{- 5}$ . That runs from a 820 m/s muzzle velocity in 0.02 s steps under gravity 9.8 m/s² until the shell lands, then divides by 2.77: the game clock runs faster than real time, and that factor was measured against stopwatch runs in the Training Room. Lower is better, since a faster shell is harder to dodge and needs less lead.

HE flight time @ 10 km4.99 s

How long an HE shell takes to reach a target at a fixed 10 km, from the same numerically integrated trajectory the Charts card plots. The shell slows under quadratic air drag,  $a_{drag} = k ρ v^{2}$ , where  $ρ$  is air density from a standard-atmosphere profile and  $k$  bundles the shell's drag coefficient, caliber and mass:  $k = \frac{π C_{d} d^{2}}{8 m} = \frac{π \cdot 0.2763 \cdot {0.381}^{2}}{8 \cdot 800} = 1.97 \times 10^{- 5}$ . That runs from a 820 m/s muzzle velocity in 0.02 s steps under gravity 9.8 m/s² until the shell lands, then divides by 2.77: the game clock runs faster than real time, and that factor was measured against stopwatch runs in the Training Room. Lower is better, since a faster shell is harder to dodge and needs less lead.

HE penetration95 mm

95 mm ≈ 380 mm caliber / 4 (improved HE penetration: German BBs, Yamato-class, and a handful of others).

Improved HE PenYes

This ship's HE shells use a 1/4 (~0.25) caliber-to-pen ratio instead of the standard 1/6 (~0.167) - 0.249 in this case. Lets HE pen ~95mm armor instead of ~63mm. Hits every German cruiser (150mm CL, 203mm CA) and BB (350mm+), British heavy cruisers / Lion / Nelson, a handful of other premiums.

AP overmatch26 mm

floor(380 mm caliber / 14.3) = 26 mm (AP auto-penetrates plating this thick or less).

AP AOE Radius120

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.

Broadside guns used for alpha8

All 8 barrels bear on the broadside.

Turret turn time30 s

180 degrees / 6 deg/s traverse speed = 30 s.

Zero upgrades: 8 broadside guns x 60 / 26 s base reload = 18.5. All upgrades (Main Battery Mod. 3 = -10% reload): 8 broadside guns x 60 / 23.4 s all-upgrades reload = 20.5.

Fires/minInitial: 6.28 → 6.97

Zero upgrades: 18.5 shells/min x 34% fire chance = 6.28. All upgrades (Main Battery Mod. 3 = -10% reload): 20.5 shells/min x 34% fire chance = 6.97.

Torpedoes

Torpedo detectability1.3 km

Estimated torpedo reaction time7.1 s

detectability / (speed kt x 2.6855 game-speed factor, m/s per knot, calibrated from in-game measurement; the community's traditional 2.6 reads about 3% slower).

Torpedo speed68 kt

Travel time to max range49.3 s

range / (speed kt x 2.6855 game-speed factor, m/s per knot, calibrated from in-game measurement).

Torpedo module damage1,000

Per-torpedo module/blast damage parameter from in-game data. Most torpedoes carry 500 to 2,000; ships announced by WG as dealing increased module damage carry 9,000 to 12,000, so their hits knock out engines, rudders, and turrets far more often. Comparative figure; the exact module-HP conversion is not published.

Tube count8

2 launchers x 4 tubes.

Per-side salvo4 torpedoes

tube count / 2 (symmetric port/starboard launcher layout; common on cruisers and battleships with deck torpedoes).

Full-salvo damage101,600

All tubes hitting one target: tubes x per-torpedo simulated damage = 8 x 12,700 = 101,600.

Per-side salvo damage50,800

One side firing, all torpedoes hitting: per-side tubes x per-torpedo simulated damage = 4 x 12,700 = 50,800.

AA defense

AA DPS at max range131

Only families that reach 4.5 km contribute at the outer edge of the AA bubble. In-game families: 37mm SKC 30 twin 8x2 -> 29 DPS @ 3.5 km; 20mm Flak 38 12x1 -> 79 DPS @ 2 km; 20mm Flack 38 quad 8x4 -> 53 DPS @ 2 km; 105 mm SKC 37 8x2 -> 131 DPS @ 4.5 km.

Maximum AA range4.5 km

Longest-reaching family on the in-game AA card. Base AirDefense aura max range is 3.5 km; dual-purpose mount auras extend it.

AA DPS layered by range131 DPS @ 4.5 km, 160 DPS @ 3.5 km, 292 DPS @ 2 km

Cumulative AA DPS at each family range threshold. Inner ranges stack the outer families, so a target closing the distance hits stronger AA bubbles as it crosses each band.

AA DPS at point-blank292

Sum of every family's average DPS, achievable only inside the closest-range family (2 km).

AA threat index955

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.

Near aura range2 km

Secondary battery dispersion

Secondary dispersion typeStandard

Max dispersion = range (km) × 57 + 30. Each dispersion type sets its own slope; this is not a percentage applied to a standard baseline.

Max secondary dispersion @ 7 km429 m

7 km × 57 + 30 = 429 m.

Secondary dispersion @ 5 km315 m

Same per-type line evaluated at a fixed 5 km: 5 km × 57 + 30 = 315 m.

Secondary battery firepower

Secondary DPM (per side)246,000

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: 8×2 105 mm (8/side) × 60/4 × 1200 = 144,000 + 4×2 150 mm (4/side) × 60/6 × 1700 = 68,000 + 2×2 150 mm (2/side) × 60/6 × 1700 = 34,000. Assumes every shell hits (real hit rate is lower; the Brawl matchup tool on the Compare page folds in dispersion + target armor).

Max HE alpha1700

Maximum HE damage per shell across secondary HE families. Best on this ship: 1700 from the 150 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 150 mm family.

Max HE pen38 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: 38 mm from the 150 mm family.

Armor Beta

Hull HP 72,500, distributed across 5 hull zones, each with its own plate thicknesses, saturation cap, and pen thresholds. HP caps are estimated from the standard WoWs damage-allocation model.

Bow & stern32 mm

Overmatched by AP from only MusashiARP Musashi. Angled, everything else bounces.

Belt / citadel315 mm

Citadels come from a flat broadside at close range; held past ~30° of angle, AP shatters or bounces.

Farming19 mm

Superstructure and extremities take HE pens and AP overpens from nearly any gun: steady chip damage. Fire resistance 37%, fires burn 60s. Range-by-range in the Compare tool →

Section	Plates	HP cap	Threats	Tactic
Bow	32 mm primary (range 20–60 mm)	≈ 3,625 (~5% of HP)	Overmatched by 460mm+ AP (Aki, Musashi)Angle bounces 410mm32 mm: HE pens from 203mm+	Bow-tank fits behind this exterior plate. Saturation is FAST here; the cap is often only a few thousand HP.
Hull (midship)	340 mm primary (range 38–340 mm)	≈ 54,375 (~75% of HP)	No common AP caliber overmatches340 mm: no common HE pens	Largest HP pool. Citadel sits behind these plates; thinner deck and side plating absorb the rest.
Stern	32 mm primary (range 32–110 mm)	≈ 3,625 (~5% of HP)	Overmatched by 460mm+ AP (Aki, Musashi)Angle bounces 410mm32 mm: HE pens from 203mm+	Mirror of bow. Same fast saturation.
Citadel	315 mm primary (range 25–340 mm)	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	19 mm primary (range 19–50 mm)	no cap	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).

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.
