Overview

Lambros Katsonis is a Tier VIII European gunboat destroyer: her damage comes from sustained main battery pressure on caps and open-water trades. Torpedoes are a secondary threat for closing lanes, not her main damage. Surveillance Radar is what sets her apart here: she can open a cap fight by revealing the defender instead of trading blind. AA (236 AA DPS at 4 km, +300% Defensive AA flak burst) runs near the top of her cohort: heavy enough to make a careless strike expensive, though not the umbrella that shuts a carrier out of her grid. Standout traits: best HE alpha in T8 DDs (2,200, 1st of 26) and HE DPM in T8 DDs (221,760, 3rd of 26). The trade is weak torpedoes in T8 DDs (9,800, 27th of 27).

Positioning

Hold mid-cap distance and lean into gunboat trades from cover where the peer destroyer cannot match your fires-per-minute. Avoid open-water duels with ships running smoke or radar; the torpedoes are a closer, not the plan, so gunfire from cover wins more than from blue water. Concretely: 11 km of reach against 7.1 km of detection leaves about 3.9 km in which you can shoot before the answer arrives. With only HE, aim at superstructures and upper-hull sections where it does full damage instead of shattering on heavy belt armor. Shooting from the cloud gives you away at 2.9 km, and a destroyer here is spotted at about 7 km, so you see it coming with roughly 4.2 km to spare. Vision is mutual: past the 2 km guaranteed ring you cannot see out either, but your own Radar (8 km) reads through it, so you can find targets instead of borrowing them. Enemy sonar (about 4.7 km) and radar (about 9 km) read straight in regardless.

Potato Avoidance

Trading guns in open water against peer DDs

Your damage is sustained main-battery pressure from cover (the torpedoes are a secondary threat), so open-water duels just stack incoming HE on you while you fire back. You are visible from 7.1 km with 20,300 HP to spend, so the second ship to join the trade decides it.

Signature Traits

Improved HE penetration

HE pen at the 1/4 caliber ratio instead of the standard 1/6. HE-spam is a real damage option here, not just a fire-starter, shared by 6/28 T8 DDs.

Torpedoes on both beams

One launcher on each beam, 4 tubes per side. Each launcher reloads on its own, so she can fire one side, turn and fire the other without waiting, or ambush ships on both sides of an island at once, shared by 5/28 T8 DDs.

Surveillance Radar

8 km range, 10 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

+5% speed (about +2.1 kt), 90 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.

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.

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 × 2,600 = 5,200), 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.

2,600

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 × 15,200 = 30,400), 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.

15,200

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 × 1,700 = 3,400), 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.

1,700

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 × 1,800 = 3,600), 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.

±148°, ±150°, 2x 226° arc, ±146°

Guns to bear

180° − 148° (the most restricted aft-facing mount's arc) = 32° off bow; 180° − 61° (the most restricted forward-facing mount's arc) = 119° 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.

Maximum simulated damage

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 = 29, 400 \cdot 0.333 = 9, 800

. 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.

≈ 9,800

Maximum damage (ammunition)

29,400 warhead alpha / 3 + 900 blast = 10,700. 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.

10,700

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.

Torpedo detectability1.6 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{1.6 km}{80 kt \times 2.6855} = 7.4 s

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

7.4 s

Flooding chance

This torpedo carries a flooding-chance value of 1.73 per hit, shown as

1.73 \times 100 = 173 %

. 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.

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 km24.9 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  $delim \cdot R_{m a x} = 0.5 \cdot 10967 = 5484$  m, and  $radiusOnMax = 0.6$  at 10967 m. Below the kink:  $k = 0.2 + (0.5 - 0.2) \cdot \frac{5000}{5484} = 0.4735$ , so  $σ_{V} = σ_{H} \cdot k = 52.5 \cdot 0.4735 = 24.9 m$ .

Shell scatter height @ 10 km52.4 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  $delim \cdot R_{m a x} = 0.5 \cdot 10967 = 5484$  m, and  $radiusOnMax = 0.6$  at 10967 m. Above the kink:  $k = 0.5 + (0.6 - 0.5) \cdot \frac{10000 - 5484}{10967 - 5484} = 0.5824$ , so  $σ_{V} = σ_{H} \cdot k = 90 \cdot 0.5824 = 52.4 m$ .

HE flight time @ 10 km5.74 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:  $k = \frac{π C_{d} d^{2}}{8 m} = \frac{π \cdot 0.234 \cdot {0.14}^{2}}{8 \cdot 39.9} = 4.51 \times 10^{- 5}$ . That runs from a 840 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.

Improved HE PenYes

This ship's HE shells use a 1/4 (~0.25) caliber-to-pen ratio instead of the standard 1/6 (~0.167) - 0.25 in this case. Lets HE pen ~35mm armor instead of ~23mm. Hits every German cruiser (150mm CL, 203mm CA) and BB (350mm+), British heavy cruisers / Lion / Nelson, a handful of other premiums.

Guns per full salvo (alpha, DPM)6

Counted from each mount's firing arc: most barrels that bear at once: 6 of 6, 32.5° off the bow (wing mounts on both sides reach it). Abeam only 5 bear.

Torpedoes

Estimated torpedo reaction time7.4 s

1600 m / (80.0 kt × 2.6855) = 7.4 s. detectability / (speed kt x 2.6855 m/s per knot on the game clock).

Torpedo speed80.0 kt

Travel time to max range41.9 s

9000 m / (80.0 kt × 2.6855) = 41.9 s. range / (speed kt x 2.6855 m/s per knot on the game clock).

Tube count8

2 launchers × 4 tubes.

Per-side salvo4 torpedoes

8 wing tubes / 2 = 4: the launchers sit one per beam, so only half of them reach any one side. Each launcher reloads on its own, so she can fire one beam, turn, and fire the other without waiting.

Full-salvo damage78,400

All tubes hitting one target: tubes x per-torpedo simulated damage = 8 x 9,800 = 78,400. Each hit on the target's torpedo belt is reduced by its torpedo protection %.

AA defense

AA DPS at max range150

Only families that reach 4 km contribute at the outer edge of the AA bubble. In-game families: 3in50 Twin Mark 33 2x2 -> 75 DPS @ 4 km; 3in50 MK34 2x1 -> 75 DPS @ 4 km; 20mm Oerlikon MK20 Twin 6x2 -> 86 DPS @ 2 km.

AA DPS layered by range150 DPS @ 4 km, 236 DPS @ 2 km

@ 4 km: 75 + 75 = 150; @ 2 km: 75 + 75 + 86 = 236. 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-blank236

75 + 75 + 86 = 236 DPS: the sum of every family's average DPS, achievable only inside the closest-range family (2 km).

AA threat index772

75 × 4 + 75 × 4 + 86 × 2 = 772. 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

In the late 1920s, Greek Navy leaders debated building more conventional ships versus fewer but stronger ones. In 1929, Greece chose the first approach, ordering four simplified destroyers from Italy. An alternative could have been ordering a pair of large ships with 5.5-inch (140 mm) guns, like the British E-class cruiser. Lambros Katsonis was named after a Greek liberation leader.

Armor Beta

Hull HP 17,300 → 20,300 with hull upgrade, distributed across 5 hull zones, each with its own plate thicknesses, saturation cap, and pen thresholds.

Bow & stern19 mm

Overmatched by 134+ AP guns across the bracket. Can’t reliably bow-tank; gets bow-citadelled and overpenned.

Farming19 mm

Superstructure and extremities take HE pens and AP overpens from nearly any gun: steady chip damage. Fire resistance 40%, fires burn 30s. Range-by-range in the Compare tool →

Section	Plates	HP cap	Threats	Tactic

Stern	19 mm primary (range 6–20 mm)	1,800 (9% of HP)	Overmatched by 283mm+ AP (Scharnhorst '43, Schill)Angle bounces 203mm19 mm: HE pens from 127mm+	Mirror of bow. Same fast saturation.
Citadel	20 mm primary (range 13–20 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	10,200 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 (76 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	6,100 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.
