Overview

Rhode Island is a Legendary American secondary battleship with top-decile secondary reach out to 7.5 km: the kit rewards closing inside secondary range and letting the auto-fire battery work alongside the mains, not holding mid-range AP lines. AA (827 AA DPS at 5 km) is heavy enough to make her the team's air-defense anchor on top of the lead role; CV strikes route around her, not through. Standout traits: secondary dispersion in Legendary BBs (232.5 m, 1st of 23) and heavy secondary DPM in Legendary BBs (302,400, 4th of 23). The trade is surface detection in Legendary BBs (16.1 km, 22nd of 23).

Positioning

Anchor a flank at 14-17 km with bow toward the closest threat, then use the speed advantage at 33 kn to rotate to the cap that needs a second battleship rather than the one your team already has. Mobility means you can pick which fight you are in; do not waste it by holding center the whole match. She is genuinely evasive in both phases of a turn, answering the helm in 12.1 s and carving a 890 m circle, so you can break a salvo and still be where you meant to go.

Potato Avoidance

Torpedo Boat Brawling

With no torpedoes you cannot trade back a fight fought inside enemy torpedo range. Hold the band where your guns and secondaries punish them while their fish still fall short, and lean on armor and volume of fire instead of closing the last few kilometers into a spread you have no answer for.

Surveillance Radar

Engine Boost

+8% speed (about +2.6 kt), 180 s duration. Engine Boost takes her to 35.6 kt, faster than 22 of 24 Legendary cruisers - enough to run down most cruisers or pull away from them, though the faster destroyers still outpace her. Uncommon in Legendary BBs.

Easily spotted ↗

16.1 km surface detect, bottom decile of Legendary BBs. Visible before you can react; position early.

No torpedo backup

A brawler with no torpedoes: every trade is guns and secondaries. The sweet spot is inside secondary range but outside easy torpedo range -- close enough that the auto-fire battery works, not so close that a destroyer or torpedo cruiser lands a salvo you can't answer.

Fire resistance

top hull: 1 − 0.6004 fire coefficient = 40%. 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.

40%

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 × 87,500 HP = 15,750 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 × 87,500 HP = 17,500 HP on this ship.

0.5% of HP per second

Torp Reduction

1 − 0.247 hull torpedo-damage coefficient / 0.333 unprotected baseline = 26%. Reduces torpedo hit damage. It does not affect flooding: floods start as often and tick at the full rate.

26%

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.

37,100

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.

26,300

Effective HP

Base 87,500 HP plus everything Repair Party can restore: 0.005 of max HP per second (0.5%) × 28 s × 87,500 HP = 12,250 HP per charge, × 3 charges = 36,750 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 × 4,600 = 9,200), 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.

4,600

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 × 10,200 = 20,400), 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 × 65,600 = 131,200), 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.

65,600

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 × 6,700 = 13,400), 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 ×. 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.

6,700

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 × 4,700 = 9,400), 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.

4,700

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° − 145° (the most restricted aft-facing mount's arc) = 35° off bow; 180° − 145° (the most restricted forward-facing mount's arc) = 35° 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 3 AA explosions in quick succession, each leaving 4 clouds ahead of the attacking squadron, plus 2 stray clouds farther out that appear off-beat between salvos - up to 14 clouds per salvo × 250 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.

Crash stop

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. The full curve is on the acceleration chart. Full reverse stops about a quarter faster than a plain Stop order from top speed.

33.4 s

Acceleration 0-99%

Time to reach 99% of top speed (32.7 kt of 33.0 kt). 99% rather than 100% because true top speed is asymptotic (thrust meets drag), so the last fraction of a knot is never quite gained.

Main battery formulas

vs standard BB17% tighter H · 17% shorter V

H = horizontal, V = vertical spread. This ship's curve against the standard battleship curve, both evaluated at this ship's max range (17.2 km) with the same model as Max Horiz/Vert Disp: horizontal 192 / 232 m − 1 = -17%, vertical 115 / 139 m − 1 = -17%. Shell grouping (σ) is separate: it sets how shells bunch toward the centre of this ellipse.

Shell scatter width @ 5 km90 m

(166.7 × (10 − 1.6) / 1000 + 1.6 × 166.7 / 166.7) × 30 = 90 m (inside the 5 km taper). 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 km132 m

(333.3 × (10 − 1.6) / 1000 + 1.6) × 30 = 132 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 km174 m

(500 × (10 − 1.6) / 1000 + 1.6) × 30 = 174 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 km33.7 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  $delim \cdot R_{m a x} = 0.5 \cdot 17160 = 8580$  m, and  $radiusOnMax = 0.6$  at 17160 m. Below the kink:  $k = 0.2 + (0.5 - 0.2) \cdot \frac{5000}{8580} = 0.3748$ , so  $σ_{V} = σ_{H} \cdot k = 90 \cdot 0.3748 = 33.7 m$ .

Shell scatter height @ 10 km68.2 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  $delim \cdot R_{m a x} = 0.5 \cdot 17160 = 8580$  m, and  $radiusOnMax = 0.6$  at 17160 m. Above the kink:  $k = 0.5 + (0.6 - 0.5) \cdot \frac{10000 - 8580}{17160 - 8580} = 0.5166$ , so  $σ_{V} = σ_{H} \cdot k = 132 \cdot 0.5166 = 68.2 m$ .

Shell scatter height @ 15 km100 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  $delim \cdot R_{m a x} = 0.5 \cdot 17160 = 8580$  m, and  $radiusOnMax = 0.6$  at 17160 m. Above the kink:  $k = 0.5 + (0.6 - 0.5) \cdot \frac{15000 - 8580}{17160 - 8580} = 0.5748$ , so  $σ_{V} = σ_{H} \cdot k = 174 \cdot 0.5748 = 100 m$ .

AP pen 5 km631 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  $P = 10^{- 7} \cdot K \cdot m^{0.69} \cdot d^{- 1.07} \cdot v^{1.38}$   $= 10^{- 7} \cdot 2995 \cdot 585^{0.69} \cdot {0.356}^{- 1.07} \cdot {709.6}^{1.38} = 631 mm$ , where 709.6 m/s is the shell's speed when it arrives at 5 km (from 823 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 km518 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  $P = 10^{- 7} \cdot K \cdot m^{0.69} \cdot d^{- 1.07} \cdot v^{1.38}$   $= 10^{- 7} \cdot 2995 \cdot 585^{0.69} \cdot {0.356}^{- 1.07} \cdot {615.3}^{1.38} = 518 mm$ , where 615.3 m/s is the shell's speed when it arrives at 10 km (from 823 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 km433 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  $P = 10^{- 7} \cdot K \cdot m^{0.69} \cdot d^{- 1.07} \cdot v^{1.38}$   $= 10^{- 7} \cdot 2995 \cdot 585^{0.69} \cdot {0.356}^{- 1.07} \cdot {540.1}^{1.38} = 433 mm$ , where 540.1 m/s is the shell's speed when it arrives at 15 km (from 823 m/s at the muzzle). Fixed anchors make ships directly comparable at the same fighting distance; the Charts card plots the full curve.

HE flight time @ 10 km5.01 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:  $k = \frac{π C_{d} d^{2}}{8 m} = \frac{π \cdot 0.325 \cdot {0.356}^{2}}{8 \cdot 578.34} = 2.8 \times 10^{- 5}$ . That runs from a 861 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.

AP flight time @ 10 km5.12 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:  $k = \frac{π C_{d} d^{2}}{8 m} = \frac{π \cdot 0.285 \cdot {0.356}^{2}}{8 \cdot 585} = 2.42 \times 10^{- 5}$ . That runs from a 823 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)12

3 mounts × 4 barrels = 12; all 12 bear on the broadside.

Model inputs

Krupp (AP)2,995

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 mass585 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 coefficient0.285

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

AP muzzle velocity823 m/s

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

HE muzzle velocity861 m/s

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

idealRadius10

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

minRadius1.6

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.

taperDist5,000 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 range641

Only families that reach 5 km contribute at the outer edge of the AA bubble. In-game families: 3in50 Twin Mark 33 14x2 -> 453 DPS @ 5 km; 3in50 Twin Mark 33 2x2 -> 65 DPS @ 5 km; 20mm Oerlikon MK4 40x1 -> 186 DPS @ 2 km; 5in38 Mk38 Mod0 10x2 -> 123 DPS @ 5 km.

AA DPS layered by range641 DPS @ 5 km, 827 DPS @ 2 km

@ 5 km: 453 + 65 + 123 = 641; @ 2 km: 453 + 65 + 186 + 123 = 827. 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-blank827

453 + 65 + 186 + 123 = 827 DPS: the sum of every family's average DPS, achievable only inside the closest-range family (2 km).

AA threat index3577

453 × 5 + 65 × 5 + 186 × 2 + 123 × 5 = 3577. 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 @ 5 km165 m

Same per-type line evaluated at a fixed 5 km: 5 km × 27 + 30 = 165 m.

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

A battleship based on a 1938 "fast battleship" design variant, featuring an alternative armament configuration. The ship's main battery consists of twelve 14-inch (356 mm) guns housed in quadruple-gun turrets, initially planned for use on North Carolina-class battleships in 1937.

Armor Beta

Hull HP 87,500, distributed across 5 hull zones, each with its own plate thicknesses, saturation cap, and pen thresholds.

Bow & stern27 mm

Overmatched by 45+ AP guns across the bracket. Can’t reliably bow-tank; gets bow-citadelled and overpenned.

Belt / citadel310 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 40%, fires burn 60s. Range-by-range in the Compare tool →

Citadel	310 mm primary (range 32–297 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	19 mm primary (range 19–38 mm)	6,700 (8% of HP)	Any HE ≥16 mm pens at full damageDamage multiplier ×0.6	Any HE ≥16 mm pens at full damage. HE-spam target, and the section saturates fast (often only a few thousand HP).
Turret (module, per magazine)	separate HP pool, does not drain ship HP	37,100 magazine HP	Turret knocked out	Per-turret powder-magazine HP, a separate pool that does not drain ship HP. As it is worn down the turret is likelier to be knocked out, and a smaller pool gets there faster.
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 (76 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	26,300 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.
