Ruggiero di Lauria is a Legendary Italian SAP battleship: her 457mm main battery fires semi-armor-piercing shells (114mm of fixed penetration) in place of AP. SAP lands a reliable guaranteed chunk on broadsides and superstructures instead of fishing for citadels, and pens without the angle checks AP lives or dies on. The catch is that SAP shatters on the heavy belt armor AP would punch through, so the kit rewards picking targets it bites over trading into an angled battleship. Her secondary battery fires SAP rather than HE, so it punches through angled plating that shatters standard secondaries in a brawl. Standout traits: best turret traverse rate in Legendary BBs (6) and best top speed in Legendary BBs (35 kt).
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.
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.
6.0°/s turret traverse, best of Legendary BBs. Tracks fast-rotating targets peers can't keep up with.
19.0 mm armor deck, bottom decile of Legendary BBs. Plunging fire and HE eat through.
0.01 s AP fuse timer, bottom decile of Legendary BBs. Detonates earlier in the plate; trades belt-citadels for reliable damage against thin targets (cruiser-on-cruiser specialty).

Not standouts for Ruggiero di Lauria -- 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.

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.SAP shell fragment splash radius; the area over which a SAP hit scatters fragment damage. Scales with shell mass (90mm ~ 5, 203mm CA ~ 20-30, 320mm = 175, 406mm = 250, 457mm = 400, max) and is tuned per ship, so two ships with the same SAP caliber can differ (135mm ranges 5-24). Larger value = wider fragment spread per hit.All 8 barrels bear on the broadside.180 degrees / 6 deg/s traverse speed = 30 s.14,900 AP damage x 8 broadside guns = 119,200.Zero upgrades: 119,200 AP full-salvo alpha x 60 / 28 s base reload = 255,429.

Here: (113×3.5×0.75) + (73×3.5×0.7) + (20×3.5×0.75) = 528. 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).

Overmatched by 7 guns here: Incomparable SE 25IncomparableYamato and 4 more. Angling still helps against the rest.
Citadels come from a flat broadside at close range; held past ~30° of angle, AP shatters or bounces.

An AP citadel penetration deals the shell's full damage, the biggest single hit available; only over-penetrations are damped, to ×0.10. |

| 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.
