Overview

Progressor is a Tier VIII Pan-Asian long-range gunboat destroyer reaching 12 km: her guns out-reach peer DDs and most cruisers can be kited at the edge of her range. The kit is long-range AP work from open water rather than cap contesting; the torpedoes are a backup, not the primary threat. She also packs the super-heal (1.5%/s, for 20 s, every 120 s, 2 charges): each Repair Party charge returns dramatically more HP than a standard heal, so her durability comes from sustain alongside the lead trait. Standout traits: best deep effective HP in T8 DDs (35,520, 1st of 12) and high HP pool in T8 DDs (22,200 HP, 4th of 28). The trade is surface detection in T8 DDs (7.3 km, 23rd of 28).

Positioning

Sit in open water at the edge of 12 km where peer DDs cannot return fire and most cruisers have to push to engage. The kit is HE pressure from distance, not cap contesting; let your peer DDs take the cap while you kite the rotating cruisers and BBs that come to support it. Your AP loses penetration at range, so aim at superstructures or pen-able hull armor, not the bow-in or belt armor it bounces and shatters on.

Potato Avoidance

Burning Main Battery Reload Booster on a hopeful salvo These torpedoes ignore the Destroyer class

With only 2 charges it is a finisher rather than an opener: spend it on a target that cannot turn away, a broadside battleship or a cruiser already committed to its own attack, where the extra salvo lands as damage instead of splashes. A booster pressed on a maybe is one you will not have when the certainty shows up. 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 3/28 T8 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.

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.

11,100

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.

6,700

Effective HP

Base 22,200 HP plus everything Repair Party can restore: 1.5%/s x 20 s = 6,660 HP per charge, x2 charges = 13,320 HP. Ceiling, not a prediction: a charge only restores damage actually taken, and only the regeneratable share of it. In practice ships realize about half of this, mostly because half the charges go unspent; a charge that is used returns about 97% of the per-charge figure above. Repair Party is one choice in its slot on this ship, so this applies only if you take it.

Bow section HP

Damage saturation pool for the bow: penetrations here deal their normal share until roughly this much damage has landed on the section, then further hits on it deal half damage. Once a section is saturated, a penetration there deals exactly half (1,125 becomes 563); hits on the ship's other, unsaturated sections still deal full damage. 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.

2,100

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 roughly this much damage has landed on the section, then further hits on it deal half damage. Once a section is saturated, a penetration there deals exactly half (1,125 becomes 563); hits on the ship's other, unsaturated sections still deal full damage. 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.

16,700

Superstructure section HP

Damage saturation pool for the superstructure: penetrations here deal their normal share until roughly this much damage has landed on the section, then further hits on it deal half damage. Once a section is saturated, a penetration there deals exactly half (1,125 becomes 563); hits on the ship's other, unsaturated sections still deal full damage. 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.

500

Stern section HP

Damage saturation pool for the stern: penetrations here deal their normal share until roughly this much damage has landed on the section, then further hits on it deal half damage. Once a section is saturated, a penetration there deals exactly half (1,125 becomes 563); hits on the ship's other, unsaturated sections still deal full damage. 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.

Range10 km

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 = 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.

≈ 14,500

Maximum damage (ammunition)

43,500 warhead alpha / 3 + 1,200 blast = 15,700. 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.

15,700

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.

1,200

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}{65 kt \times 2.6855} = 4.6 s

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

4.6 s

Flooding chance

This torpedo carries a flooding-chance value of 3.02 per hit, shown as

3.02 \times 100 = 302 %

. 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.

AA explosions

Each ~2 s salvo fires 2 AA explosions in quick succession, each leaving 2 clouds ahead of the attacking squadron - up to 4 clouds per salvo × 250 damage each. Planes that fly into a cloud take its damage; clouds dissipate before the next salvo lands. Defensive AA Fire, where fitted, multiplies the AA explosions within each salvo, and commander skills that raise the Number of AA explosions add to it.

Cloud damage

Flak zone

The activation band: flak fires while attacking planes are inside it. Clouds are placed ahead of the planes' path, so clouds can land short of 2.5 km or past 5.2 km - once planes get inside the band, new salvos stop. AA range bonuses push the outer edge out; the 2.5 km inner edge does not move.

Traverse-to-turn ratio

How many degrees the turret can swing for each degree the hull turns. Turn rate

ω_{hull} = \frac{180}{π} \cdot \frac{V_{max} (m/s)}{R_{turn}} = \frac{180}{π} \cdot \frac{35.0 \cdot 0.5144}{700} = 1.47 ° / s

, so

ratio = \frac{ω_{turret}}{ω_{hull}} = \frac{18}{1.47} = 12.2 \times

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 km23.6 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  $delim \cdot R_{m a x} = 0.5 \cdot 12000 = 6000$  m, and  $radiusOnMax = 0.6$  at 12000 m. Below the kink:  $k = 0.2 + (0.5 - 0.2) \cdot \frac{5000}{6000} = 0.45$ , so  $σ_{V} = σ_{H} \cdot k = 52.5 \cdot 0.45 = 23.6 m$ .

Shell scatter height @ 10 km51 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  $delim \cdot R_{m a x} = 0.5 \cdot 12000 = 6000$  m, and  $radiusOnMax = 0.6$  at 12000 m. Above the kink:  $k = 0.5 + (0.6 - 0.5) \cdot \frac{10000 - 6000}{12000 - 6000} = 0.5667$ , so  $σ_{V} = σ_{H} \cdot k = 90 \cdot 0.5667 = 51 m$ .

AP pen 5 km176 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  $P = 10^{- 7} \cdot K \cdot m^{0.69} \cdot d^{- 1.07} \cdot v^{1.38}$ . Fixed anchors make ships directly comparable at the same fighting distance; the Charts card plots the full curve.

AP pen 10 km104 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  $P = 10^{- 7} \cdot K \cdot m^{0.69} \cdot d^{- 1.07} \cdot v^{1.38}$ . Fixed anchors make ships directly comparable at the same fighting distance; the Charts card plots the full curve.

AP flight time @ 10 km5.7 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:  $k = \frac{π C_{d} d^{2}}{8 m} = \frac{π \cdot 0.23 \cdot {0.13}^{2}}{8 \cdot 23} = 6.64 \times 10^{- 5}$ . That runs from a 975 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)4

2 mounts × 2 barrels = 4; all 4 bear on the broadside.

Model inputs

Krupp (AP)3,000

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 mass23 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 coefficient0.23

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

AP muzzle velocity975 m/s

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

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 time4.6 s

800 m / (65.0 kt × 2.6855) = 4.6 s. detectability / (speed kt x 2.6855 m/s per knot on the game clock).

Torpedo speed65.0 kt

Travel time to max range57.3 s

10000 m / (65.0 kt × 2.6855) = 57.3 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 range46

Only families that reach 5.2 km contribute at the outer edge of the AA bubble. In-game families: 57mm Type 66 4x2 -> 140 DPS @ 4 km; 25mm Type 61 4x2 -> 53 DPS @ 2.5 km; Far AA (?) -> 46 DPS @ 5.2 km.

AA DPS layered by range46 DPS @ 5.2 km, 186 DPS @ 4 km, 239 DPS @ 2.5 km

@ 5.2 km: 46 from one family; @ 4 km: 140 + 46 = 186; @ 2.5 km: 140 + 53 + 46 = 239. 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-blank239

140 + 53 + 46 = 239 DPS: the sum of every family's average DPS, achievable only inside the closest-range family (2.5 km).

AA threat index932

140 × 4 + 53 × 2.5 + 46 × 5.2 = 932. 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.

Near aura range2.5 km

Background

From 1949 through 1956, a scientific and technical support program was in effect between the U.S.S.R. and P.R.C. Under this program, the Soviets shared the blueprints of promising warships with China - including the technical documentation for the Project 41 destroyer. While China didn't build any ships of this project in its original form, they built fifteen 051-class (Luda-class) missile destroyers from 1968 through 1987 that were based on Project 41.

Armor Beta

Hull HP 22,200, distributed across 5 hull zones, each with its own plate thicknesses, saturation cap, and pen thresholds. HP caps are estimates.

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

Hull (midship)	19 mm	≈ 16,650 (~75% of HP)	Overmatched by 283mm+ AP (Scharnhorst '43, Schill)Angle bounces 203mm19 mm: HE pens from 127mm+	Largest HP pool. Citadel sits behind these plates; thinner deck and side plating absorb the rest.
Stern	19 mm primary (range 6–20 mm)	≈ 1,110 (~5% 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)	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.
Superstructure	19 mm	no cap	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).

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.
