Omaha Build & Guide | WoWs Legends

Playstyle

Overview

Omaha is a Tier IV American light cruiser with Sonar as her vision tool. Hydro lets her contest islands and smoke without exposing the hull to vision cycles, which shapes how she pressures caps.

Positioning

Sit 10-13 km from a contested cap where an island shadows you from the opposite battleship line. Hydro (4.1 km on ships, 3 km on torpedoes) lights up DDs and incoming torpedoes inside its bubble, so you can push the cap edge from cover without taking the spotting cycle; prefer cover positions over open-water flanks.

Potato Avoidance

Open-water broadside trading

Her 152mm shells citadel cruisers on the wrong frame, and her 26,800-HP hull does not recover from a punished salvo. Pick rotations and angles deliberately; the chip-damage role pays better than the trade-blow role on a cruiser of this profile.

Signature Traits

Fast turret traverse

10.0°/s turret traverse, best of T4 CAs. Tracks fast-rotating targets peers can't keep up with.

High fire pressure

8.0 fires/min, top decile of T4 CAs. Keeps DCP on cooldown.

Fire-starter cruiser

Fires per minute in the top bracket. Keeps enemy DCP burning on cooldown.

Heavy belt

Citadel belt in the top bracket. Incoming AP rarely citadels through angle.

Short AA reach

3.1 km AA reach, bottom decile of T4 CAs. Drops bombs and rockets land before AA bites.

Acquisition

How to get Omaha

Omaha is available in the Early U.S. Cruisers branch of the U.S. Tech Tree for 500,000 credits after researching it in the branch. Known module upgrades cost up to 100,000 credits.

U.S. Tech Tree

Omaha sits in the Early U.S. Cruisers branch. The highlighted path shows the local branch context inside the full U.S. tree.

The early U.S. cruisers focus on providing a powerful broadside from their rapid-firing guns, and they are your starting point to the U.S. Tech Trees. From Tier III, you gain access to a useful self-defense tool: Sonar.

Advantages: High rate of fire, Sonar consumable starting at Tier III
Disadvantages: Limited main battery firing angles, Low-velocity shells

Builds Beta

AL Baltimore, AL Montpelier, and Captain Janeway are useful American cruiser commander directions. Inspirations usually support accuracy, reload, concealment, agility, or survivability so the ship can keep influencing fights without giving up easy citadels.

Armor

Hull HP 23,100 → 26,800 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	25 mm primary (range 10–37 mm)	3,500 (13% of HP)	Overmatched by 380mm+ (Bayern)Angle bounces 356mm25 mm: HE pens from 150mm+	Bow-tank fits behind this exterior plate. Saturation is FAST here; the cap is often only a few thousand HP.
Hull (midship)	6 mm primary (range 6–38 mm)	20,100 (75% of HP)	Overmatched by 127mm+ (Shenyang, Nicholas)6 mm: HE pens from 127mm+	Largest HP pool. Citadel sits behind these plates; thinner deck and side plating absorb the rest.

Citadel	76 mm primary (range 13–76 mm)	≈ 165,500 (effectively no cap)	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).
Superstructure	10 mm primary (range 10–37 mm)	1,100 (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	13,400 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.
AA mount (28 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	8,000 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.
