Overview

Gadjah Mada is a Tier VI Pan-Asian gun-and-torpedo destroyer (6.9 km surface detection and 10 km torpedoes): her guns and torpedoes rank close together against her tier's destroyers, so neither carries her alone. Fight the enemy destroyers with the guns and save the deep-water torpedoes for the cruisers and battleships that come to support them; they pass under destroyers. Standout traits: main battery range in T6 DDs (11.1 km, 3rd of 41) and best smoke duration in T6 DDs (30 s, 3rd of 36). The trade is torpedo reload in T6 DDs (120 s, 39th of 41).

Positioning

Play the cap edge where both weapons reach: close enough to trade gunfire with the enemy destroyer, while the deep-water torpedoes cover the cruisers and battleships behind it (they pass under destroyers). Go dark between trades so the next salvo or wave is on your terms, and leave before the radar or spot timer matters. Your guns lose penetration at range, so aim AP at broadsides you can still citadel and put HE into superstructures and upper-hull sections, rather than the bow-in or belt armor your shells bounce and shatter on. Shooting from the cloud gives you away at 2.5 km, and a destroyer here is spotted at about 6.9 km, so you see it coming with roughly 4.5 km to spare. Vision is mutual: past the 2 km guaranteed ring you cannot see out either, but your own Radar (7.5 km) reads through it, so you can find targets instead of borrowing them. Enemy sonar (about 4.2 km) and radar (about 9 km) read straight in regardless. Once the rudder is over she turns tightly for her cohort (590 m), so a committed turn costs less water than most of what she is fighting.

Potato Avoidance

Playing her as only one kind of destroyer These torpedoes ignore the Destroyer class

Holding the torpedoes to keep a gun duel going, or skipping gun trades while you wait for a perfect torpedo window, leaves half the kit idle; she wins fights by using both. Aim torpedo drops ONLY at battleships, carriers, and most cruisers; every torp fired at a DD is wasted output.

Signature Traits

Deep-water torpedoes

Torps IGNORE the Destroyer class (deep-water mechanic); they pass under DDs and cannot hit them. Aim ONLY at battleships, carriers, and most cruisers; every torp fired at a DD is wasted, shared by 3/41 T6 DDs.

Surveillance Radar

7.5 km range, 15 s duration. Detects all enemy ships within a fixed radius regardless of line-of-sight. A short scan - long enough to break a smoke camp or call a target for the team, not to hold a cap.

Engine Boost

+8% speed (about +2.9 kt), 120 s duration. Engine Boost consumable gives a small speed nudge - useful for closing a gap or steadying a torpedo run, not for running anything down.

Long gun range ↗

11.1 km main battery reach, top decile of T6 DDs.

Long smoke deployment ↗

30 s smoke deployment window, best of T6 DDs. Lays a longer rolling smoke trail while moving.

Slow torp reload ↗

120 s torpedo reload, bottom decile of T6 DDs. Long wait between drops.

Fire resistance

stock hull: 1 − 0.7336 fire coefficient = 26.6%; top hull: 1 − 0.7003 fire coefficient = 30%. Lowers how often hits set you on fire. It does not reduce the damage a burning fire does per second; fires burn at the full rate on every ship.

Fire duration30 s

Fire damage

One unattended fire: 0.003 of max HP per second (0.3%) × 30 s = 0.09 of the pool; 0.09 × 14,300 HP = 1,287 HP on this ship. 4 fire points can burn at once.

0.3% of HP per second

Flood duration40 s

Flood damage

One unattended flood: 0.0025 of max HP per second (0.25%) × 40 s = 0.1 of the pool; 0.1 × 14,300 HP = 1,430 HP on this ship.

0.25% of HP per second

Torp Reduction

1 − 0.333 hull torpedo-damage coefficient / 0.333 unprotected baseline = 0%. Reduces torpedo hit damage. It does not affect flooding: floods start as often and tick at the full rate.

Magazine HP

Per-turret powder-magazine HP, a separate pool from the ship's. Penetrating hits wear it down and the turret is likelier to be knocked out as it falls, so a larger pool keeps the guns firing through punishment that silences a peer's.

Steering gear HP

Durability of the steering gears. As this pool drops, hits are likelier to jam the rudder; unlike most modules the steering can be knocked out and repaired but is never permanently destroyed.

Bow section HP

Damage saturation pool for the bow: penetrations here deal their normal share until twice this much penetration damage has landed on the section (2 × 2,300 = 4,600), then further hits on it deal half damage. A penetration deals 0.33 × the shell's max damage; once the section is saturated it deals exactly half of that (0.5 × 0.33 = 0.165 × max damage), so a 3,000-damage shell's pen goes from 990 to 495. Overpens (0.1 × max damage) and citadels (1.0 ×) ignore saturation. Pens on the ship's other, unsaturated sections still deal the normal 0.33 ×. A larger pool keeps that part of the ship taking full damage for longer; a small one saturates fast and protects the ship's HP.

2,300

Casemate section HP

This section has no practical saturation cap: every hit here keeps dealing its normal share of damage (on most ships the citadel; on many destroyers the casemate).

No saturation cap

Hull section HP

Damage saturation pool for the hull: penetrations here deal their normal share until twice this much penetration damage has landed on the section (2 × 10,700 = 21,400), then further hits on it deal half damage. A penetration deals 0.33 × the shell's max damage; once the section is saturated it deals exactly half of that (0.5 × 0.33 = 0.165 × max damage), so a 3,000-damage shell's pen goes from 990 to 495. Overpens (0.1 × max damage) and citadels (1.0 ×) ignore saturation. Pens on the ship's other, unsaturated sections still deal the normal 0.33 ×. A larger pool keeps that part of the ship taking full damage for longer; a small one saturates fast and protects the ship's HP.

10,700

Superstructure section HP

Damage saturation pool for the superstructure: penetrations here deal their normal share until twice this much penetration damage has landed on the section (2 × 700 = 1,400), then further hits on it deal half damage. A penetration deals 0.33 × the shell's max damage; once the section is saturated it deals exactly half of that (0.5 × 0.33 = 0.165 × max damage), so a 3,000-damage shell's pen goes from 990 to 495. Overpens (0.1 × max damage) and citadels (1.0 ×) ignore saturation. Pens on the ship's other, unsaturated sections still deal the normal 0.33 ×. The superstructure is not exempt: it saturates exactly like the bow and stern, so shells aimed at it stop dealing full damage once this pool is used up. A larger pool keeps that part of the ship taking full damage for longer; a small one saturates fast and protects the ship's HP.

700

Stern section HP

Damage saturation pool for the stern: penetrations here deal their normal share until twice this much penetration damage has landed on the section (2 × 1,300 = 2,600), then further hits on it deal half damage. A penetration deals 0.33 × the shell's max damage; once the section is saturated it deals exactly half of that (0.5 × 0.33 = 0.165 × max damage), so a 3,000-damage shell's pen goes from 990 to 495. Overpens (0.1 × max damage) and citadels (1.0 ×) ignore saturation. Pens on the ship's other, unsaturated sections still deal the normal 0.33 ×. A larger pool keeps that part of the ship taking full damage for longer; a small one saturates fast and protects the ship's HP.

Turret traverse arcs

How far each mount can train, in degrees to either side of the mount's own facing. A rear turret with ±150° leaves a 60° blind wedge over the bow; one-sided arcs are wing mounts that cover a single side. The data does not say which way each mount faces, so the arcs are listed per mount without bow/stern angles.

±115°

Guns to bear

180° − 167° (the most restricted aft-facing mount's arc) = 13° off bow; 180° − 115° (the most restricted forward-facing mount's arc) = 65° off stern. How far off the bow (or stern) the ship must angle before every main turret can fire: the widest blind wedge among the rear-facing (or forward-facing) mounts, from each mount's trainable arc.

Torpedoes

ModuleTorpedoes: 533 mm QR Mk VI

Launchers / tubes2 launchers × 5 tubes = 10 tubes

Reload time

Base reload of the top torpedo module (all-upgrades configuration); the stock module reloads in 130 s. Modernizations and commander effects scale it further, e.g. Torpedo Launchers Mod. 3 alone is x0.85:

120 \times 0.85 = 102

Initial: 130 s → 120 s

Projectile speed

Speed of the top torpedo module (all-upgrades configuration, 62.0 kt); the stock torpedo module runs 60.0 kt.

Initial: 60 kt → 62 kt

RangeInitial: 8.04 km → 9.99 km

Maximum simulated damage

Initial: 42,000 × 0.333 = 14,000 → 43,500 × 0.333 = 14,500 (warhead alpha × saturation coefficient, stock → upgraded torpedo). Most targets only intersect one hull section, so a hit transfers about 1/3 of the warhead alpha (2/3 when the warhead blast >= 5000 and the burst reaches a second section). For this ship:

D_{sim} = α \cdot c = 43, 500 \cdot 0.333 = 14, 500

. In battle, a hit on the torpedo belt deals the per-hit figure × (1 − the target's torpedo protection %), a bow or stern hit deals it in full, and a torpedo never counts as a citadel hit.

Initial: ≈ 14,000 → ≈ 14,500

Maximum damage (ammunition)

43,500 warhead alpha / 3 + 1,000 blast = 15,500. Warhead alpha / 3 plus the blast addend: the per-torpedo damage figure. The 'Maximum simulated damage' row above applies target geometry to the same warhead.

15,500

Torpedo module damage

Per-torpedo module/blast damage parameter. Most torpedoes carry 500 to 2,000; ships announced by WG as dealing increased module damage carry 9,000 to 12,000, so their hits knock out engines, rudders, and turrets far more often. Comparative figure.

1,000

Torpedo detectability0.8 km

Reaction time

How long a target has to dodge after your torpedo is spotted at its detectability range (lower means less warning):

t_{react} = \frac{0.8 km}{62 kt \times 2.6855} = 4.8 s

. 2.6855 converts knots to m/s on the game clock. Base value; commander torpedo-concealment skills lower it further.

4.8 s

Flooding chance

This torpedo carries a flooding-chance value of 3.22 per hit, shown as

3.22 \times 100 = 322 %

. Values above 100% are normal: in battle the base chance is scaled down by the target's torpedo protection (the Torp Reduction stat on its Survivability card) and any flood-resistance modifiers, so a value above 100% keeps flooding likely even through partial protection.

Crash stop

Seconds from top speed to a dead stop after ordering full reverse: reverse power winds in over the reverse spool-up while water drag does most of the braking, using the ship's own reverse-power ratio. The full curve is on the acceleration chart. Full reverse stops about a quarter faster than a plain Stop order from top speed.

16.6 s

Acceleration 0-99%

Time to reach 99% of top speed (35.6 kt of 36.0 kt). 99% rather than 100% because true top speed is asymptotic (thrust meets drag), so the last fraction of a knot is never quite gained.

Guns in a full turn

With the rudder hard over the hull turns 7.9°/s, so a target drifts across the bow at that rate. Turret traverse minus hull turn: 10 − 7.9 = +2.1°/s, so the guns hold the target through the turn. Main Battery Mod. 2 (+20% traverse) and Mod. 3 (−15%) move this line.

Main battery formulas

vs standard DDStandard

The standard destroyer dispersion curve.

Shell scatter width @ 5 km52.5 m

(166.7 × (8 − 0.5) / 1000 + 0.5) × 30 = 52.5 m. Horizontal scatter at a fixed 5 km, from the same dispersion model as the rows below - a knife-fight-range anchor comparable across ships.

Shell scatter width @ 10 km90 m

(333.3 × (8 − 0.5) / 1000 + 0.5) × 30 = 90 m. How wide your shells scatter at 10 km, from the same dispersion model as the max-range figure above. Picking a fixed range makes this number directly comparable from ship to ship: max-range dispersion makes a longer-range gun look worse even when it's tighter at any common range. The interactive Dispersion tab on the Charts card plots the full curve from 0 to max range.

Shell scatter height @ 5 km24.6 m

How tall the scatter ellipse is at a fixed 5 km, from the same model, comparable from ship to ship. The height/width ratio is a piecewise-linear curve through three points from the ship's own dispersion data:  $radiusOnZero = 0.2$  at 0 m,  $radiusOnDelim = 0.5$  at  $delim \cdot R_{m a x} = 0.5 \cdot 11139.7 = 5570$  m, and  $radiusOnMax = 0.6$  at 11139.7 m. Below the kink:  $k = 0.2 + (0.5 - 0.2) \cdot \frac{5000}{5570} = 0.4693$ , so  $σ_{V} = σ_{H} \cdot k = 52.5 \cdot 0.4693 = 24.6 m$ .

Shell scatter height @ 10 km52.2 m

How tall the same scatter ellipse is at 10 km. Comparable from ship to ship for the same reason as the width value above. The height/width ratio is a piecewise-linear curve through three points from the ship's own dispersion data:  $radiusOnZero = 0.2$  at 0 m,  $radiusOnDelim = 0.5$  at  $delim \cdot R_{m a x} = 0.5 \cdot 11139.7 = 5570$  m, and  $radiusOnMax = 0.6$  at 11139.7 m. Above the kink:  $k = 0.5 + (0.6 - 0.5) \cdot \frac{10000 - 5570}{11139.7 - 5570} = 0.5795$ , so  $σ_{V} = σ_{H} \cdot k = 90 \cdot 0.5795 = 52.2 m$ .

AP pen 5 km92 mm

AP penetration at a fixed 5 km, from the same ballistic curve as AP Pen Close/Far: the shell's impact velocity at that range fed through the AP formula  $P = 10^{- 7} \cdot K \cdot m^{0.69} \cdot d^{- 1.07} \cdot v^{1.38}$   $= 10^{- 7} \cdot 2438 \cdot {22.68}^{0.69} \cdot {0.12}^{- 1.07} \cdot {445.3}^{1.38} = 92 mm$ , where 445.3 m/s is the shell's speed when it arrives at 5 km (from 808 m/s at the muzzle). Fixed anchors make ships directly comparable at the same fighting distance; the Charts card plots the full curve.

AP pen 10 km46 mm

AP penetration at a fixed 10 km, from the same ballistic curve as AP Pen Close/Far: the shell's impact velocity at that range fed through the AP formula  $P = 10^{- 7} \cdot K \cdot m^{0.69} \cdot d^{- 1.07} \cdot v^{1.38}$   $= 10^{- 7} \cdot 2438 \cdot {22.68}^{0.69} \cdot {0.12}^{- 1.07} \cdot {268.5}^{1.38} = 46 mm$ , where 268.5 m/s is the shell's speed when it arrives at 10 km (from 808 m/s at the muzzle). Fixed anchors make ships directly comparable at the same fighting distance; the Charts card plots the full curve.

HE flight time @ 10 km8.6 s

How long an HE shell takes to reach a target at a fixed 10 km, from the same numerically integrated trajectory the Charts card plots. The shell slows under quadratic air drag,  $a_{drag} = k ρ v^{2}$ , where  $ρ$  is air density from a standard-atmosphere profile and  $k$  bundles the shell's drag coefficient, caliber and mass:  $k = \frac{π C_{d} d^{2}}{8 m} = \frac{π \cdot 0.3927 \cdot {0.12}^{2}}{8 \cdot 22.68} = 9.79 \times 10^{- 5}$ . That runs from a 808 m/s muzzle velocity in 0.02 s steps under gravity 9.8 m/s² until the shell lands, then divides by 2.77 because the game clock runs faster than real time. Lower is better, since a faster shell is harder to dodge and needs less lead.

AP flight time @ 10 km8.6 s

How long an AP shell takes to reach a target at a fixed 10 km, from the same numerically integrated trajectory the Charts card plots. The shell slows under quadratic air drag,  $a_{drag} = k ρ v^{2}$ , where  $ρ$  is air density from a standard-atmosphere profile and  $k$  bundles the shell's drag coefficient, caliber and mass:  $k = \frac{π C_{d} d^{2}}{8 m} = \frac{π \cdot 0.3927 \cdot {0.12}^{2}}{8 \cdot 22.68} = 9.79 \times 10^{- 5}$ . That runs from a 808 m/s muzzle velocity in 0.02 s steps under gravity 9.8 m/s² until the shell lands, then divides by 2.77 because the game clock runs faster than real time. Lower is better, since a faster shell is harder to dodge and needs less lead.

Guns per full salvo (alpha, DPM)6

3 mounts × 2 barrels = 6; all 6 bear on the broadside.

Model inputs

Krupp (AP)2,438

Armor-penetration constant of the AP shell; penetration scales straight with it, so a 10% higher Krupp is 10% more penetration at every range.

AP shell mass22.68 kg

Enters penetration as mass^0.69 and slows the shell's drag deceleration, so a heavier shell keeps more velocity at range.

AP drag coefficient0.3927

Air drag on the AP shell in flight; lower keeps velocity, and with it penetration, at long range.

AP muzzle velocity808 m/s

Starting speed of the AP shell; penetration scales with velocity^1.38.

HE muzzle velocity808 m/s

Starting speed of the HE shell; sets its flight time and lead.

idealRadius8

Horizontal dispersion growth per idealDistance of range, in 30 m units; the slope of the scatter-width line.

minRadius0.5

Horizontal dispersion at zero range, in 30 m units; the intercept of the scatter-width line.

idealDistance1,000 m

Range step over which horizontal dispersion grows by idealRadius.

taperDist4,000 m

Inside this range the scatter width tapers toward minRadius instead of following the line.

radiusOnZero0.2

Vertical scatter as a share of horizontal at zero range.

radiusOnDelim0.5

Vertical scatter as a share of horizontal at the delim point.

radiusOnMax0.6

Vertical scatter as a share of horizontal at maximum range.

delim0.5

Where the vertical-scatter curve bends, as a share of maximum range.

Torpedoes

Estimated torpedo reaction time4.8 s

800 m / (62.0 kt × 2.6855) = 4.8 s. detectability / (speed kt x 2.6855 m/s per knot on the game clock).

Torpedo speed62.0 kt

Travel time to max range60 s

9990 m / (62.0 kt × 2.6855) = 60 s. range / (speed kt x 2.6855 m/s per knot on the game clock).

Tube count10

2 launchers × 5 tubes.

Per-side salvo10 torpedoes

2 launchers × 5 tubes = 10, all to either side (centreline launchers train across - full salvo to either side).

Full-salvo damage145,000

All tubes hitting one target: tubes x per-torpedo simulated damage = 10 x 14,500 = 145,000. Each hit on the target's torpedo belt is reduced by its torpedo protection %.

AA defense

AA DPS at max range63

Only families that reach 3.5 km contribute at the outer edge of the AA bubble. In-game families: 40mm Bofors Mark IV Hazemeyer 1x2 -> 63 DPS @ 3.5 km; 20mm Oerlikon MK20 Twin 4x2 -> 76 DPS @ 2 km.

AA DPS layered by range63 DPS @ 3.5 km, 139 DPS @ 2 km

@ 3.5 km: 63 from one family; @ 2 km: 63 + 76 = 139. Cumulative AA DPS at each family range threshold. Inner ranges stack the outer families, so a target closing the distance hits stronger AA bubbles as it crosses each band.

AA DPS at point-blank139

63 + 76 = 139 DPS: the sum of every family's average DPS, achievable only inside the closest-range family (2 km).

AA threat index372

63 × 3.5 + 76 × 2 = 372. 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.

Background

The N-class destroyer. She was built in Britain and then transferred to the Royal Netherlands Navy. In 1951, the ship was sold to Indonesia. This destroyer, armed with powerful artillery guns and torpedo tubes, had a very successful design for her time.

Armor Beta

Hull HP 12,000 → 14,300 with hull upgrade, distributed across 5 hull zones, each with its own plate thicknesses, saturation cap, and pen thresholds.

Bow & stern16 mm

Overmatched by 126+ AP guns across the bracket. Can’t reliably bow-tank; gets bow-citadelled and overpenned.

Farming16 mm

Superstructure and extremities take HE pens and AP overpens from nearly any gun: steady chip damage. Fire resistance 30%, fires burn 30s. Range-by-range in the Compare tool →

Section	Plates	HP cap	Threats	Tactic
Bow	16 mm primary (range 15–16 mm)	2,300 (16% of HP)	Overmatched by 283mm+ AP (Graf Spee, Scharnhorst)Angle bounces 203mm16 mm: HE pens from 127mm+	Bow-tank fits behind this exterior plate. Saturation is FAST here; the cap is often only a few thousand HP.
Hull (midship)	16 mm	10,700 (75% of HP)	Overmatched by 283mm+ AP (Graf Spee, Scharnhorst)Angle bounces 203mm16 mm: HE pens from 127mm+	Largest HP pool. Citadel sits behind these plates; thinner deck and side plating absorb the rest.
Stern	16 mm primary (range 15–16 mm)	1,300 (9% of HP)	Overmatched by 283mm+ AP (Graf Spee, Scharnhorst)Angle bounces 203mm16 mm: HE pens from 127mm+	Mirror of bow. Same fast saturation.
Citadel	16 mm primary (range 10–16 mm)	≈ 165,500 (effectively no cap)	Citadel pen: full damageOver-pen: ×0.10 damage	Effectively no cap; citadel pool sits at ~165k HP on every ship. 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	7,200 magazine HP	Turret knocked out	Per-turret powder-magazine HP, a separate pool that does not drain ship HP. As it is worn down the turret is likelier to be knocked out, and a smaller pool gets there faster.
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	4,300 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.
