Ruggiero di Lauria Build & Guide | WoWs Legends

Playstyle

Overview

Ruggiero di Lauria is a Legendary Italian fast battleship at 35 kn. Mobility lets her rotate flanks battleship-fast and pick fights where her guns get the first salvo.

Positioning

Anchor a flank at 14-17 km with bow toward the closest threat, then use the speed advantage at 35 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.

Potato Avoidance

Using the 35-kn speed to push rather than to rotate

The mobility advantage is about picking which cap fight you arrive at, not about leading the brawl line; a fast BB that overextends loses HP that the kit cannot trade back.

Signature Traits

Fast turret traverse

6.0°/s turret traverse, best of Legendary BBs. Tracks fast-rotating targets peers can't keep up with.

Fast for the class

35.0 kt, best of Legendary BBs. Lets you rotate flanks or escape disengagements.

Heavy powerplant

235000.0 hp engine, top decile of Legendary BBs. More headroom for accelerating out of stops and maintaining speed in turns.

Nimble for the tonnage

4.07 hp per ton, top decile of Legendary BBs. Engine punch outclasses the hull's mass, so the ship retains speed through sustained turns better than peers.

Slow acceleration

~11.0 s to max forward speed, worst of Legendary BBs. Sluggish rebuild after a turn or stop. (Acceleration decode is validated in-game but not yet confirmed across every ship.)

Short AA reach

4.0 km AA reach, bottom quartile of Legendary BBs. Drops bombs and rockets land before AA bites.

Magazine HP

ƒ

The magazine is the module a detonation comes from. Penetrating hits to it raise the detonation chance from 1% toward 30% as its HP is worn down, so a larger magazine pool rides out citadel hits longer before a detonation becomes likely.

AA threat index1606

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.

Secondary DPM (per side)136,822

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: 8×2 135 mm (8/side) × 60/10.7 × 3050 = 136,822. Assumes every shell hits (real hit rate is lower; the Brawl matchup tool on the Compare page folds in dispersion + target armor).

Max SAP alpha3050

Maximum SAP damage per shell across secondary SAP families. Best on this ship: 3050 from the 135 mm family.

Max SAP pen38 mm

Maximum SAP armor penetration across secondary SAP families. SAP auto-bounces past its ricochet angles but never shatters on plate it can pen, and it starts no fires. Best on this ship: 38 mm from the 135 mm family.

Armor

Hull HP 79,200, 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.

Section	Plates	HP cap	Threats	Tactic
Bow	32 mm primary (range 32–50 mm)	5,500 (7% of HP)	Overmatched by 460mm+ (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)	100 mm primary (range 32–457 mm)	59,400 (75% of HP)	No common 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	32 mm primary (range 32–100 mm)	3,000 (4% of HP)	Overmatched by 460mm+ (Aki, Musashi)Angle bounces 410mm32 mm: HE pens from 203mm+	Mirror of bow. Same fast saturation.
Citadel	457 mm primary (range 19–457 mm)	≈ 165,500 (effectively no cap)	Citadel pen ×0.40 damageOver-pen: ×0.10 damage	Effectively no cap; citadel pool sits at ~165k HP on every ship. Damage is gated by pen/over-pen multipliers instead (×0.40 direct pen, ×0.10 over-pen).
Superstructure	19 mm primary (range 19–400 mm)	3,300 (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	39,600 magazine HP	Magazine detonation1–30% chance · below ~75% HP	Per-turret powder-magazine HP. Detonation chance scales from 1% (no mag damage) to 30% (full mag damage); this range is the in-game value. Detonation can't roll while the ship is above ~75% HP (the standard detonation-protection threshold, not a per-ship stat). Smaller magazines saturate to the 30% ceiling faster.
Secondary mount (135 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 (37 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	23,800 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.
