Overview

Baltimore is a Tier VII American heavy cruiser whose signature kit is Surveillance Radar (9 km). The radar drop is what makes her valuable in cap fights; the guns are the secondary story. AA (540 AA DPS at 5 km, +100% Defensive AA flak burst) ranks 5 of 57 in T7 CAs: heavy enough to make a careless strike expensive, though not the umbrella that shuts a carrier out of her grid. Standout traits: best AP always-pen window in T7 CAs (60°) and end-plate armor (27 mm).

Positioning

Hold 12-15 km from a contested cap with an island close enough to break sightline when focus shifts. Push the radar forward only once the destroyer fight is yours; burning the drop to fish for a lone DD kill leaves the next push with no answer to smoke or vision. The helm answers quickly (7.1 s), so she can break an incoming salvo that slower hulls have to eat.

Potato Avoidance

Using radar like a destroyer hunter rather than a position tool

The consumable's value is locking down a cap your team can take, not stealing a single salvo on a lone DD. Burn it early to fish for a kill and the next push has no answer to smoke or vision. Yours reaches 9 km for 30 s, which is the whole window your team gets to act on what it shows.

Acquisition

How to get Baltimore

Baltimore is available in the Bombarding Heavy Cruisers branch of the U.S. Tech Tree for 18,000,000 credits after researching it in the branch. Known module upgrades cost up to 3,600,000 credits.

U.S. Tech Tree

Baltimore sits in the Bombarding Heavy Cruisers branch. The highlighted path shows the local branch context inside the full U.S. tree.

U.S. heavy cruisers are well suited to bombarding enemy ships with powerful, super-heavy armor-piercing shells and high-explosive shells, but they lack torpedoes entirely. Starting from Tier VII, they bring Radar and Sonar together to the battle to detect hidden enemy warships.

Advantages: Improved AP shells, Long-duration Radar starting at Tier VII
Disadvantages: Low-velocity shells, Poor protection

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.

Initial: 33.3% → 36.6%

Fire duration30 s

Fire damage

Each fire ticks 0.3% of max HP per second for the full 30 s, so one unattended fire burns 9% of the pool (3,816 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 0.25% of max HP per second for the 40 s duration, so one unattended flood costs 10% of the pool (4,240 HP on this ship). Verified against measured flood ticks in replay data.

0.25% 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.

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.

21,200

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.

12,700

Effective HP

Base 42,400 HP plus everything Repair Party can restore: 0.6%/s x 28 s = 7,123 HP per charge, x2 charges = 14,246 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.

3x ±150°

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.

Bursts

Each ~2 s wave fires 2 quick salvos of 4 clouds ahead of the attacking squadron, plus 1 stray cloud farther out that appear off-beat between waves - up to 9 clouds per wave × 230 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.

230

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.

90%

Wave rate

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

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 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.

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. Same community-model simulation as the acceleration times, using the ship's own reverse-power ratio from in-game data. The full curve is on the acceleration chart.

Acceleration 0-90%

Time to reach 90% of top speed (29.2 kt of 32.5 kt), from our in-house acceleration model.

26.5 s

Acceleration 0-99%

Time to reach 99% of top speed (32.2 kt of 32.5 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.

43.4 s

Traverse-to-turn ratio

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

ω_{hull} = \frac{180}{π} \cdot \frac{V_{max} (m/s)}{R_{turn}} = \frac{180}{π} \cdot \frac{32.5 \cdot 0.5144}{730} = 1.31 ° / s

, so

ratio = \frac{ω_{turret}}{ω_{hull}} = \frac{7}{1.31} = 5.3 \times

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 km136.5 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 Disp83.8 m at 15.5 km

Vertical dispersion ellipse height at max range: $σ_{V} = σ_{H} \cdot radiusOnMax$ $= 139.7 \cdot 0.6 = 83.8 m$

Shell scatter height @ 10 km54 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  $delim \cdot R_{m a x} = 0.5 \cdot 15469.3 = 7735$  m, and  $radiusOnMax = 0.6$  at 15469.3 m. Above the kink:  $k = 0.5 + (0.6 - 0.5) \cdot \frac{10000 - 7735}{15469.3 - 7735} = 0.5293$ , so  $σ_{V} = σ_{H} \cdot k = 102 \cdot 0.5293 = 54 m$ .

Med Horiz Disp44.1 m at 15.5 km

50%-hit horizontal radius: $σ_{H, 50} = σ_{H} \cdot \frac{0.6}{σ}$ $= 139.7 \cdot \frac{0.6}{1.9} = 44.1 m$

Med Vert Disp26.5 m at 15.5 km

50%-hit vertical radius: $σ_{V, 50} = σ_{V} \cdot \frac{0.6}{σ}$ $= 83.8 \cdot \frac{0.6}{1.9} = 26.5 m$

AP Pen Close506.2 mm point-blank

Canonical community AP formula (jcw780/wows_shell), evaluated at muzzle velocity:  $P = 10^{- 7} \cdot K \cdot m^{0.69} \cdot d^{- 1.07} \cdot v_{0}^{1.38}$   $= 10^{- 7} \cdot 2919 \cdot 152^{0.69} \cdot {0.203}^{- 1.07} \cdot 782^{1.38} = 506.2 mm$ . Matches the in-game spec card.

AP Pen Far199.9 mm at 15.5 km

Same formula at the ship's max firing range (15.5 km), where the shell has slowed to 398.8 m/s:  $P = 10^{- 7} \cdot 2919 \cdot 152^{0.69} \cdot {0.203}^{- 1.07} \cdot {398.8}^{1.38} = 199.9 mm$ .

AP pen 5 km322 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 km226 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 km167 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 km5.61 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:  $k = \frac{π C_{d} d^{2}}{8 m} = \frac{π \cdot 0.321 \cdot {0.203}^{2}}{8 \cdot 118} = 4.4 \times 10^{- 5}$ . That runs from a 853 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 km5.88 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:  $k = \frac{π C_{d} d^{2}}{8 m} = \frac{π \cdot 0.333 \cdot {0.203}^{2}}{8 \cdot 118} = 4.57 \times 10^{- 5}$ . 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: 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 penetration34 mm

34 mm ≈ 203 mm caliber / 6 (standard HE penetration ratio).

AP overmatch14 mm

floor(203 mm caliber / 14.3) = 14 mm (AP auto-penetrates plating this thick or less).

AP AOE Radius45

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.

AA defense

AA DPS at max range98

Only families that reach 5 km contribute at the outer edge of the AA bubble. In-game families: 40mm Bofors 12x4 -> 296 DPS @ 3.5 km; 20mm Oerlikon MK4 23x1 -> 146 DPS @ 2 km; 5in38 Mk32 Mod12 6x2 -> 98 DPS @ 5 km.

Maximum AA range5 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 range98 DPS @ 5 km, 394 DPS @ 3.5 km, 540 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-blank540

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

AA threat index1818

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 @ 5 km315 m

5 km × 57 + 30 = 315 m.

Secondary battery firepower

Secondary DPM (per side)108,000

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: 6×2 127 mm (6/side) × 60/6 × 1800 = 108,000. Assumes every shell hits (real hit rate is lower; the Brawl matchup tool on the Compare page folds in dispersion + target armor).

Max HE alpha1800

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

Max HE fire chance5%

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

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.

Armor Beta

Hull HP 36,600 → 42,400 with hull upgrade, 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.

Bow & stern27 mm

Overmatched by 68+ AP guns across the bracket. Can’t reliably bow-tank; gets bow-citadelled and overpenned.

Belt / citadel152 mm

AP can citadel a flat broadside even at range. Stay angled and avoid showing the full side.

Citadel	152 mm primary (range 6–160 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 6–38 mm)	1,600 (4% 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).
Turret (module, per magazine)	separate HP pool, does not drain ship HP	21,200 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 (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	12,700 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.
