Log in to GamingDiver and upload your data to see Community Data for Mahan: community win rate, damage, survival, spotting, and your own comparison.
Mahan is a Tier V American stealth destroyer with cohort-best surface detection (6.8 km). The kit opens detection windows other DDs cannot, so her value is contesting caps her peer DDs cannot reach unspotted. Standout traits: best armor plate in T5 DDs (21 mm) and best turret traverse rate in T5 DDs (18).
Push deep into caps with 6.8 km detection - closer than peer DDs can match. The advantage opens windows for free torpedo drops and unspotted reposition; treat the cap as yours to take rather than yours to contest.
Every salvo lights you up and gives back the detection edge that makes the kit work; reserve guns for finishing damage on already-spotted ships, and prioritize torpedo drops you can fire while undetected.
+8% speed, 120 s duration. Engine Boost consumable temporarily raises top speed. Mobility on demand to reposition, chase a kill, or break contact.
21.0 mm max plate, best of T5 DDs.
5.0 km AA reach, best of T5 DDs.
5.0% fire chance per HE shell, bottom decile of T5 DDs. AP carries more weight.
Mahan is available in the Universal Destroyers branch of the U.S. Tech Tree for 2,400,000 credits after researching it in the branch. Known module upgrades cost up to 480,000 credits.
Mahan sits in the Universal Destroyers branch. The highlighted path shows the local branch context inside the full U.S. tree.
U.S. destroyers are "jacks-of-all-trades" and masters of none. They can perform in nearly any role needed from a destroyer: spotting the enemy, showering them in fire-starting shells, or unleashing torpedoes.
Build for concealment, gun reload, survivability, smoke utility, and torpedo range/reload.

Where Mahan sits among Tier V DDs (25 ships). Notable standouts are shown first; the rest of the cohort-ranked stats are in the expand below. Acquisition variants (Black Friday, Founders Edition) are counted once with their base ship, not as separate peers.
Not standouts for Mahan -- here's where she sits on every other ranked stat in the cohort. Stats tagged NORM are tied across more than half the cohort, so the value is the cohort default rather than a standout.

HP caps are the exact in-game values, not estimated.
Overmatched by 91+ guns across the bracket. Can’t reliably bow-tank; gets bow-citadelled and overpenned.
Superstructure and extremities take HE pens and AP overpens from nearly any gun: steady chip damage. Fire resistance 23%, fires burn 30s. Range-by-range in the Compare tool →

| 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. |
| Superstructure | 6 mm primary (range 6–21 mm) | 800 (6% 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 | 6,700 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. |
| AA mount (20 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 | 4,000 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.
