Overview

Kheper is a Tier VI American battleship with 406mm guns at 15.9 km on a 32-second reload. Her damage profile is AP into broadside targets and HE for chip pressure when no broadsides are available. AA (646 AA DPS at 5 km) ranks 3 of 32 in T6 BBs: heavy enough to make a careless strike expensive, though not the umbrella that shuts a carrier out of her grid. Standout traits: best heavy AP shells in T6 BBs (13,100, 2nd of 32) and flat AP trajectory in T6 BBs (71.7, 3rd of 32). The trade is AP arming threshold in T6 BBs (68 mm, 25th of 32).

Positioning

Anchor a flank at 12-15 km with bow toward the closest threat. Rotate one or two map cells with the team rather than holding solo; a battleship alone on a flank is a free focus target for the enemy. 58,000 HP is what a rotation started too late costs, and it is spent before the guns that punished it come off cooldown. With 17.4 s on the rudder she starts turning late, so the angle has to be set before you are shot at.

Potato Avoidance

Spending the spotter on a target that is already dodging

The extra range only converts if the shot was going to land: save it for the salvos that matter, an exposed broadside cruiser or a battleship committed to its angle, where the reach turns a maybe into a citadel. Popped over a jinking destroyer it buys you a longer look at your own shells missing.

20 s Damage Control duration, best of T6 BBs. Stays fire / flood immune longer per activation.

Stiff AP fuse ↗

68 mm AP arming threshold, bottom decile of T6 BBs. Over-pens thin plates; the trade-off pays off when most targets are battleship belt armor.

Sluggish rudder ↗

Fire resistance

top hull: 1 − 0.7003 fire coefficient = 30%. Lowers how often hits set you on fire. It does not reduce the damage a burning fire does per second; fires burn at the full rate on every ship.

30%

Fire duration60 s

Fire damage

One unattended fire: 0.003 of max HP per second (0.3%) × 60 s = 0.18 of the pool; 0.18 × 58,000 HP = 10,440 HP on this ship. 4 fire points can burn at once.

0.3% of HP per second

Flood duration40 s

Flood damage

One unattended flood: 0.005 of max HP per second (0.5%) × 40 s = 0.2 of the pool; 0.2 × 58,000 HP = 11,600 HP on this ship.

0.5% of HP per second

Torp Reduction

1 − 0.27 hull torpedo-damage coefficient / 0.333 unprotected baseline = 19%. Reduces torpedo hit damage. It does not affect flooding: floods start as often and tick at the full rate.

19%

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.

30,000

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.

17,900

Effective HP

Base 58,000 HP plus everything Repair Party can restore: 0.0066 of max HP per second (0.66%) × 28 s × 58,000 HP = 10,718 HP per charge, × 3 charges = 32,155 HP. Ceiling, not a prediction: a charge only restores damage actually taken, and only the regeneratable share of it. In practice ships realize about half of this, mostly because half the charges go unspent; a charge that is used returns about 97% of the per-charge figure above.

Bow section HP

Damage saturation pool for the bow: penetrations here deal their normal share until twice this much penetration damage has landed on the section (2 × 3,200 = 6,400), then further hits on it deal half damage. A penetration deals 0.33 × the shell's max damage; once the section is saturated it deals exactly half of that (0.5 × 0.33 = 0.165 × max damage), so a 3,000-damage shell's pen goes from 990 to 495. Overpens (0.1 × max damage) and citadels (1.0 ×) ignore saturation. Pens on the ship's other, unsaturated sections still deal the normal 0.33 ×. A larger pool keeps that part of the ship taking full damage for longer; a small one saturates fast and protects the ship's HP.

3,200

Casemate section HP

Damage saturation pool for the casemate: penetrations here deal their normal share until twice this much penetration damage has landed on the section (2 × 9,200 = 18,400), then further hits on it deal half damage. A penetration deals 0.33 × the shell's max damage; once the section is saturated it deals exactly half of that (0.5 × 0.33 = 0.165 × max damage), so a 3,000-damage shell's pen goes from 990 to 495. Overpens (0.1 × max damage) and citadels (1.0 ×) ignore saturation. Pens on the ship's other, unsaturated sections still deal the normal 0.33 ×. A larger pool keeps that part of the ship taking full damage for longer; a small one saturates fast and protects the ship's HP.

Hull section HP

Damage saturation pool for the hull: penetrations here deal their normal share until twice this much penetration damage has landed on the section (2 × 52,300 = 104,600), then further hits on it deal half damage. A penetration deals 0.33 × the shell's max damage; once the section is saturated it deals exactly half of that (0.5 × 0.33 = 0.165 × max damage), so a 3,000-damage shell's pen goes from 990 to 495.

A larger pool keeps that part of the ship taking full damage for longer; a small one saturates fast and protects the ship's HP.

52,300

Superstructure section HP

Damage saturation pool for the superstructure: penetrations here deal their normal share until twice this much penetration damage has landed on the section (2 × 3,300 = 6,600), then further hits on it deal half damage. A penetration deals 0.33 × the shell's max damage; once the section is saturated it deals exactly half of that (0.5 × 0.33 = 0.165 × max damage), so a 3,000-damage shell's pen goes from 990 to 495. Overpens (0.1 × max damage) and citadels (1.0 ×) ignore saturation. Pens on the ship's other, unsaturated sections still deal the normal 0.33 ×. The superstructure is not exempt: it saturates exactly like the bow and stern, so shells aimed at it stop dealing full damage once this pool is used up. A larger pool keeps that part of the ship taking full damage for longer; a small one saturates fast and protects the ship's HP.

3,300

Stern section HP

Damage saturation pool for the stern: penetrations here deal their normal share until twice this much penetration damage has landed on the section (2 × 2,400 = 4,800), then further hits on it deal half damage. A penetration deals 0.33 × the shell's max damage; once the section is saturated it deals exactly half of that (0.5 × 0.33 = 0.165 × max damage), so a 3,000-damage shell's pen goes from 990 to 495. Overpens (0.1 × max damage) and citadels (1.0 ×) ignore saturation. Pens on the ship's other, unsaturated sections still deal the normal 0.33 ×. A larger pool keeps that part of the ship taking full damage for longer; a small one saturates fast and protects the ship's HP.

Citadel section HP

This section has no practical saturation cap: every hit here keeps dealing its normal share of damage (on most ships the citadel; on many destroyers the casemate).

Turret traverse arcs

How far each mount can train, in degrees to either side of the mount's own facing. 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.

Guns to bear

180° − 148° (the most restricted aft-facing mount's arc) = 32° off bow; 180° − 149° (the most restricted forward-facing mount's arc) = 31° off stern. 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.

AA explosions

Each ~2 s salvo fires 2 AA explosions in quick succession, each leaving 5 clouds ahead of the attacking squadron, plus 1 stray cloud farther out that appear off-beat between salvos - up to 11 clouds per salvo × 200 damage each. Planes that fly into a cloud take its damage; clouds dissipate before the next salvo lands. Defensive AA Fire, where fitted, multiplies the AA explosions within each salvo, and commander skills that raise the Number of AA explosions add to it.

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 salvos 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.

Salvo interval

A new flak salvo (the AA explosions above) fires roughly every 2 s.

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

Flak zone

The activation band: flak fires while attacking planes are inside it. Clouds are placed ahead of the planes' path, so clouds can land short of 2.5 km or past 5 km - once planes get inside the band, new salvos stop. AA range bonuses push the outer edge out; the 2.5 km inner edge does not move.

Seconds from top speed to a dead stop after ordering full reverse: reverse power winds in over the reverse spool-up while water drag does most of the braking, using the ship's own reverse-power ratio.

Main battery formulas

vs standard BBStandard

The standard battleship dispersion curve.

Shell scatter width @ 5 km110 m

(166.7 × (12 − 2) / 1000 + 2) × 30 = 110 m. Horizontal scatter at a fixed 5 km, from the same dispersion model as the rows below - a knife-fight-range anchor comparable across ships.

Shell scatter width @ 10 km160 m

(333.3 × (12 − 2) / 1000 + 2) × 30 = 160 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.

Shell scatter width @ 15 km210 m

(500 × (12 − 2) / 1000 + 2) × 30 = 210 m. Horizontal scatter at a fixed 15 km, from the same dispersion model - the long-range anchor. Only shown when the ship's guns reach 15 km.

Shell scatter height @ 5 km42.8 m

How tall the scatter ellipse is at a fixed 5 km, from the same model, comparable from ship to ship. 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  $delim \cdot R_{m a x} = 0.5 \cdot 15885.1 = 7943$  m, and  $radiusOnMax = 0.6$  at 15885.1 m. Below the kink:  $k = 0.2 + (0.5 - 0.2) \cdot \frac{5000}{7943} = 0.3889$ , so  $σ_{V} = σ_{H} \cdot k = 110 \cdot 0.3889 = 42.8 m$ .

Shell scatter height @ 10 km84.1 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  $delim \cdot R_{m a x} = 0.5 \cdot 15885.1 = 7943$  m, and  $radiusOnMax = 0.6$  at 15885.1 m. Above the kink:  $k = 0.5 + (0.6 - 0.5) \cdot \frac{10000 - 7943}{15885.1 - 7943} = 0.5259$ , so  $σ_{V} = σ_{H} \cdot k = 160 \cdot 0.5259 = 84.1 m$ .

Shell scatter height @ 15 km123.7 m

How tall the scatter ellipse is at a fixed 15 km, from the same model. Only shown when the ship's guns reach 15 km. 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  $delim \cdot R_{m a x} = 0.5 \cdot 15885.1 = 7943$  m, and  $radiusOnMax = 0.6$  at 15885.1 m. Above the kink:  $k = 0.5 + (0.6 - 0.5) \cdot \frac{15000 - 7943}{15885.1 - 7943} = 0.5889$ , so  $σ_{V} = σ_{H} \cdot k = 210 \cdot 0.5889 = 123.7 m$ .

AP pen 5 km666 mm

AP penetration at a fixed 5 km, from the same ballistic curve as AP Pen Close/Far: the shell's impact velocity at that range fed through the AP formula  $P = 10^{- 7} \cdot K \cdot m^{0.69} \cdot d^{- 1.07} \cdot v^{1.38}$   $= 10^{- 7} \cdot 2598 \cdot 1225^{0.69} \cdot {0.406}^{- 1.07} \cdot {625.8}^{1.38} = 666 mm$ , where 625.8 m/s is the shell's speed when it arrives at 5 km (from 701 m/s at the muzzle). Fixed anchors make ships directly comparable at the same fighting distance; the Charts card plots the full curve.

AP pen 10 km574 mm

AP penetration at a fixed 10 km, from the same ballistic curve as AP Pen Close/Far: the shell's impact velocity at that range fed through the AP formula  $P = 10^{- 7} \cdot K \cdot m^{0.69} \cdot d^{- 1.07} \cdot v^{1.38}$   $= 10^{- 7} \cdot 2598 \cdot 1225^{0.69} \cdot {0.406}^{- 1.07} \cdot {561.7}^{1.38} = 574 mm$ , where 561.7 m/s is the shell's speed when it arrives at 10 km (from 701 m/s at the muzzle). Fixed anchors make ships directly comparable at the same fighting distance; the Charts card plots the full curve.

AP pen 15 km503 mm

AP penetration at a fixed 15 km, from the same ballistic curve as AP Pen Close/Far: the shell's impact velocity at that range fed through the AP formula  $P = 10^{- 7} \cdot K \cdot m^{0.69} \cdot d^{- 1.07} \cdot v^{1.38}$   $= 10^{- 7} \cdot 2598 \cdot 1225^{0.69} \cdot {0.406}^{- 1.07} \cdot {510.6}^{1.38} = 503 mm$ , where 510.6 m/s is the shell's speed when it arrives at 15 km (from 701 m/s at the muzzle). Fixed anchors make ships directly comparable at the same fighting distance; the Charts card plots the full curve.

AP flight time @ 10 km5.81 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:  $k = \frac{π C_{d} d^{2}}{8 m} = \frac{π \cdot 0.352 \cdot {0.406}^{2}}{8 \cdot 1225} = 1.86 \times 10^{- 5}$ . That runs from a 701 m/s muzzle velocity in 0.02 s steps under gravity 9.8 m/s² until the shell lands, then divides by 2.77 because the game clock runs faster than real time. Lower is better, since a faster shell is harder to dodge and needs less lead.

HE flight time @ 10 km5.19 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:  $k = \frac{π C_{d} d^{2}}{8 m} = \frac{π \cdot 0.346 \cdot {0.406}^{2}}{8 \cdot 862} = 2.6 \times 10^{- 5}$ . 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 because the game clock runs faster than real time. Lower is better, since a faster shell is harder to dodge and needs less lead.

Guns per full salvo (alpha, DPM)9

3 mounts × 3 barrels = 9; all 9 bear on the broadside.

Model inputs

Krupp (AP)2,598

Armor-penetration constant of the AP shell; penetration scales straight with it, so a 10% higher Krupp is 10% more penetration at every range.

AP shell mass1,225 kg

Enters penetration as mass^0.69 and slows the shell's drag deceleration, so a heavier shell keeps more velocity at range.

AP drag coefficient0.352

Air drag on the AP shell in flight; lower keeps velocity, and with it penetration, at long range.

AP muzzle velocity701 m/s

Starting speed of the AP shell; penetration scales with velocity^1.38.

HE muzzle velocity820 m/s

Starting speed of the HE shell; sets its flight time and lead.

idealRadius12

Horizontal dispersion growth per idealDistance of range, in 30 m units; the slope of the scatter-width line.

minRadius2

Horizontal dispersion at zero range, in 30 m units; the intercept of the scatter-width line.

idealDistance1,000 m

Range step over which horizontal dispersion grows by idealRadius.

taperDist4,000 m

Inside this range the scatter width tapers toward minRadius instead of following the line.

radiusOnZero0.2

Vertical scatter as a share of horizontal at zero range.

radiusOnDelim0.5

Vertical scatter as a share of horizontal at the delim point.

radiusOnMax0.6

Vertical scatter as a share of horizontal at maximum range.

delim0.5

Where the vertical-scatter curve bends, as a share of maximum range.

AA defense

AA DPS at max range134

Only families that reach 5 km contribute at the outer edge of the AA bubble. In-game families: 40mm Bofors Mk2 15x4 -> 294 DPS @ 3.5 km; 20mm Oerlikon MK4 44x1 -> 218 DPS @ 2 km; 5in38 Mk32 Mod12 10x2 -> 134 DPS @ 5 km.

AA DPS layered by range134 DPS @ 5 km, 428 DPS @ 3.5 km, 646 DPS @ 2 km

@ 5 km: 134 from one family; @ 3.5 km: 294 + 134 = 428; @ 2 km: 294 + 218 + 134 = 646. 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-blank646

294 + 218 + 134 = 646 DPS: the sum of every family's average DPS, achievable only inside the closest-range family (2 km).

AA threat index2135

294 × 3.5 + 218 × 2 + 134 × 5 = 2135. 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 firepower

Max HE alpha1800

The only family (127 mm): 1800. Maximum HE damage per shell across secondary HE families. Best on this ship: 1800 from the 127 mm family.

Max HE fire chance5%

The only family (127 mm): 5%. 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.

Max HE pen21 mm

The only family (127 mm): 21 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.

Background

The first U.S. battleship of the new generation. The key advantage over her predecessors of this type was significantly increased speed. In contrast to preceding ships of the same type, she featured a thinner armor belt, but had very solid horizontal armor protection and a superior AA armament including numerous dual-purpose artillery.

Armor Beta

Hull HP 58,000, distributed across 5 hull zones, each with its own plate thicknesses, saturation cap, and pen thresholds. HP caps are estimates.

Bow & stern26 mm

Overmatched by 81+ AP guns across the bracket. Can’t reliably bow-tank; gets bow-citadelled and overpenned.

Belt / citadel305 mm

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

Farming16 mm

Superstructure and extremities take HE pens and AP overpens from nearly any gun: steady chip damage. Fire resistance 30%, fires burn 60s. Range-by-range in the Compare tool →

Section	Plates	HP cap	Threats	Tactic
Bow	26 mm primary (range 26–40 mm)	≈ 2,900 (~5% of HP)	Overmatched by 380mm+ AP (Bayern, Richelieu)Angle bounces 356mm26 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)	100 mm primary (range 19–406 mm)	≈ 43,500 (~75% of HP)	No common AP caliber overmatches100 mm: standard HE shatters; improved HE (DE / FR BB) pens from 406mm+	Largest HP pool. Citadel sits behind these plates; thinner deck and side plating absorb the rest.
Stern	26 mm primary (range 26–378 mm)	≈ 2,900 (~5% of HP)	Overmatched by 380mm+ AP (Bayern, Richelieu)Angle bounces 356mm26 mm: HE pens from 203mm+	Mirror of bow. Same fast saturation.
Citadel	305 mm primary (range 13–305 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	16 mm primary (range 16–37 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.
