Log in to GamingDiver and upload your data to see Community Data for Pyotr Bagration B: community win rate, damage, survival, spotting, and your own comparison.
Pyotr Bagration B is a Tier VII Soviet light cruiser whose signature kit is Surveillance Radar (11.7 km). The radar drop is what makes her valuable in cap fights; the guns are the secondary story. Standout traits: top-decile fast AP shells in T7 CAs (4.8 s) and top-decile sigma in T7 CAs (2.1).
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 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.
11.7 km range, 23 s duration. Detects all enemy ships within a fixed radius regardless of line-of-sight. Controls caps and punishes smoke-firing DDs.
11.7 km Surveillance Radar range, best of T7 CAs. Lights targets peer radars can't reach.
131.0 s torpedo reload, bottom decile of T7 CAs. Long wait between drops.
13.97 km surface detect, bottom decile of T7 CAs. Visible before you can react; position early.

Where Pyotr Bagration B sits among Tier VII CAs (56 ships). Notable standouts are shown first; the rest of the cohort-ranked stats are in the expand below. Acquisition variants (Black Friday, Founders Edition) are counted once with their base ship, not as separate peers.
Not standouts for Pyotr Bagration B -- here's where she sits on every other ranked stat in the cohort. Stats tagged NORM are tied across more than half the cohort, so the value is the cohort default rather than a standout.

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.
Horizontal dispersion ellipse width at max range, from the verified WoWS dispersion model: Horizontal scatter at a fixed 5 km, from the same verified dispersion model as the rows below - a knife-fight-range anchor comparable across ships.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.Horizontal scatter at a fixed 15 km, from the same verified dispersion model - the long-range anchor.

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. Flak is NOT included: flak stops triggering once planes are inside 2.5 km, and its avoidable burst damage is shown separately in the Flak bursts section.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) × 57 + 30. Each dispersion type sets its own slope; this is not a percentage applied to a standard baseline.5 km × 57 + 30 = 315 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: 8×2 100 mm (8/side) × 60/4 × 1400 = 168,000.

Best on this ship: 6% from the 100 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: 17 mm from the 100 mm family.Hull HP 43,000, 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.
Overmatched by 102+ guns across the bracket. Can’t reliably bow-tank; gets bow-citadelled and overpenned.
AP can citadel a flat broadside even at range. Stay angled and avoid showing the full side.
Superstructure and extremities take HE pens and AP overpens from nearly any gun: steady chip damage. Fire resistance 37%, fires burn 30s. Range-by-range in the Compare tool →

| Citadel | 152 mm primary (range 25–152 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 16–38 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.
