Overview

Ragnarok is a Tier VI Japanese tank battleship (66,500 HP): top-decile hit points let her hold trades that drain peer BBs out faster than the shells they fire back. The kit is line-holder, not striker.

Positioning

Anchor a flank at 14-17 km where the team can rotate behind you. The HP pool lets you absorb focus that drains peer BBs out, but absorbing focus without trading is just wasted HP; pick salvo targets that exploit the angle others avoid.

Potato Avoidance

Absorbing focus without trading back

The HP pool is a tool for holding the angle while you reload, not a license to sit broadside; every salvo you skip is a salvo your team had to land instead.

Signature Traits

Big-caliber overmatch

28.7 mm overmatch threshold, top decile of T6 BBs. Punishes bow-tanking ships peers can't crack.

Close-range AP brick

803.7 mm AP pen at 1.5 km, top decile of T6 BBs. Citadels broadside cruisers up close.

Long-range AP brick

464.4 mm AP pen at max range, top decile of T6 BBs. Threatens citadels even from range.

Punchy HE secondaries

2400.0 max HE alpha per secondary shell, best of T6 BBs. Bigger per-shell damage than peers.

Hardened superstructure

356.0 mm superstructure, best of T6 BBs. HE farms less.

Stiff AP fuse

68.0 mm AP arming threshold, bottom decile of T6 BBs. Over-pens thin plates; the trade-off pays off when most targets are battleship belt armor.

Acquisition

How to get Ragnarok

Ragnarok is a Premium ship and not available to unlock in the Tech Tree. Acquisition paths: Containers and Collaboration. Container chances are shown as the listed odds of receiving this exact ship, dividing grouped ship-pool odds across the resolved ships and including nested container paths when a crate can drop another crate.

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 battery firepower

Secondary DPM (per side)262,800
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: 4×2 127 mm (4/side) × 60/5 × 2100 = 100,800 + 18×1 140 mm (9/side) × 60/8 × 2400 = 162,000. Assumes every shell hits (real hit rate is lower; the Brawl matchup tool on the Compare page folds in dispersion + target armor).
Max HE alpha2400
Maximum HE damage per shell across secondary HE families. Best on this ship: 2400 from the 140 mm family.
Max HE fire chance10%
Maximum per-shell fire chance across secondary HE families (before target fire resistance is applied). Best on this ship: 10% from the 140 mm family.
Max HE pen23 mm
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: 23 mm from the 140 mm family.

Armor

Hull HP 66,500, 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.

Overmatched by 283mm+ (Graf Spee, Scharnhorst)Angle bounces 203mm16 mm: HE pens from 127mm+

Citadel305 mm primary (range 25–305 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).
Superstructure356 mm2,200 (3% 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 HP33,300 magazine HPMagazine detonation1–30% chance · below ~75% HPPer-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 (140 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 (25 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 HP20,000 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.
