Overview
Dewa is the Tier VIII Japanese airstrike battleship. Her right-trigger fires a line of dive bombers in place of torpedoes, which gives her a damage source that does not need line of sight on top of her main battery. AA (762 AA DPS at 5 km) is heavy enough to make her the team's air-defense anchor on top of the lead role; CV strikes route around her, not through. Standout traits: best sigma in T8 BBs (2.1) and best AP shell velocity in T8 BBs (870).
Positioning
Park 14-17 km from a contested cap with island cover within one rotation of your bow. The airstrike line wants to cross the cap and the predictable retreat lane, both of which favor positions a little further back than a brawler would take. Open-water lanes are pure downside; you do not need line of sight to score with the airstrike, so cover is free upside.
Potato Avoidance
Launching airstrikes at maneuvering targets
The squadron's travel time is long enough that a healthy DD or cruiser with engine boost simply turns out of the cone. Reserve strikes for capping destroyers, island-huggers, and anyone already tying up with a teammate.
Signature Traits
Right-trigger fires a bomber line in place of torpedoes. Rewards behind-cover positioning with the cap in range.
Sigma 2.1, best of T8 BBs. More shells land near aim.
870.0 m/s AP muzzle velocity, best of T8 BBs. Flatter trajectory, less lead, harder to dodge.
2600.0 max HE alpha per secondary shell, best of T8 BBs. Bigger per-shell damage than peers.
762.0 AA DPS, best of T8 BBs (median 533.0).
28.7 s rudder shift, worst of T8 BBs. Hard to dodge incoming AP; lean on island cover.
How to get Dewa
Dewa is available in the Aviation Battleships branch of the Japan Tech Tree for 25,000,000 credits after researching it in the branch. Known module upgrades cost up to 6,250,000 credits. Official source cards below may also show its temporary Early Access window before it became a normal Tech Tree unlock. 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.

Builds Beta
Primary tech-tree. Jisaburō Ozawa carries the full airstrike skill suite and his Hidden Hand adds +1 squadron and cuts cooldown 50% (roughly doubles strike output across a match). Pair with Commander Worf (Sky Attack trait: more damage per dropped projectile) for raw damage, or Jonathan Hawke (Big Game Hunter trait: more airstrike damage vs BB / CA / CV) for big-target focus.

Hull HP 77,800 → 83,000 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.
| Section | Plates | HP cap | Threats | Tactic |
|---|---|---|---|---|
| Bow | 32 mm primary (range 32–356 mm) | 4,500 (5% 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) | 32 mm primary (range 22–410 mm) | 62,300 (75% of HP) | Overmatched by 460mm+ (Aki, Musashi)Angle bounces 410mm32 mm: HE pens from 203mm+ | Largest HP pool. Citadel sits behind these plates; thinner deck and side plating absorb the rest. |
| Stern | 32 mm primary (range 32–356 mm) | 3,100 (4% of HP) | Overmatched by 460mm+ (Aki, Musashi)Angle bounces 410mm32 mm: HE pens from 203mm+ | Mirror of bow. Same fast saturation. |
| Citadel | 410 mm primary (range 38–410 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 | 19 mm primary (range 19–410 mm) | 1,400 (2% 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 | 39,500 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 (155 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 (40 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 | 24,900 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.

Balance History
Balance updates affecting Dewa. Cards are condensed; use each source link for full context.
June Update: The Ages Betwixt
- We've slightly nerfed Commander Johan Furstner's skills:
- Minister of the Navy:
- Fire damage caused by your cruiser's shells or bombs will be increased by up to 4% instead of 5%.
- Risk Theory:
- Outgoing damage while your cruiser is undetected will be increased by 1/2/3/4% instead of 1.25/2.5/3.75/5%.
- Nerfs: Propulsion Mod. 2; Normal, Epic, and Legendary Secondary Battery Mod. 3.
- Starting from June 1, two Commanders will be added to general and national Commander crates:
- Spanish battleship Commander José Ferrándiz y Niño will be added to the Commander crate and Spanish Commander crate.
- Pan-American cruiser Commander Joaquim Marques Lisboa will be added to the Commander crate.
Ministry of Balance: Summertime Refit
- Stock torpedo damage reduced from 4,700 to 4,433.
- Upgraded torpedo damage reduced from 5,200 to 4,900.
Ministry of Balance: Viva la Marina!
- Air Support: Special-effect activation distance reduced from 7.5/8/8.5/9 km to 7/7.4/7.7/8 km.
- Hidden Hand: Airstrike-launched torpedo damage penalty deepened: now -25/22/18/15% (was -20/17/13/10%).
