Overview

C. Colombo is a Legendary Italian secondary battleship with top-decile secondary reach out to 7 km: the kit rewards closing inside secondary range and letting the auto-fire battery work alongside the mains, not holding mid-range AP lines. Standout traits: best AP shell velocity in Legendary BBs (850) and best flat HE shells in Legendary BBs (880).

Positioning

Push to within secondary range (~7 km) so the secondary battery starts contributing damage. A secondary BB at mid range is wasting half her kit; the geometry that pays out is close enough that the secondaries DPM peer BBs instead of the main battery alone.

Potato Avoidance

Holding mid-range AP lines like a standard BB

The secondary battery is half the kit, so a mid-range secondary BB is leaving damage on the table every minute; commit to the brawl angle or play a different ship.

Signature Traits

Flat AP shells

850.0 m/s AP muzzle velocity, best of Legendary BBs. Flatter trajectory, less lead, harder to dodge.

Flat HE shells

880.0 m/s HE muzzle velocity, best of Legendary BBs. Flatter trajectory, easier to land at range.

Wide always-pen zone

50.0° AP min ricochet angle, best of Legendary BBs. Larger impact-angle window where shells always penetrate.

Late auto-bounce

65.0° AP guaranteed ricochet angle, best of Legendary BBs. Auto-bounce kicks in later than peers'.

Loose grouping

Sigma 1.6, bottom decile of Legendary BBs. Shells scatter more; bracketing matters.

Slow reload

30.2 s reload, bottom decile of Legendary BBs. Salvos punish more, but cycle is slower than peers.

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.

Per-family: 6×3 152 mm (9/side) × 60/8.5 × 3800 = 241,412 + 12×2 90 mm (12/side) × 60/6 × 2000 = 240,000. Assumes every shell hits (real hit rate is lower; the Brawl matchup tool on the Compare page folds in dispersion + target armor).

Citadel pen ×0.10 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 (×0.10 direct pen, ×0.10 over-pen).

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 (152 mm mount)separate HP pool, does not drain ship HP800 per-mount HPDestroyed at 0 HPPer-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 HP200 per-mount HPDestroyed at 0 HPPer-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 HP24,000 module HPIncapacitated at 0 HPWhen 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.
