Mahan — American Tier VII destroyer.

Developed from the Farragut class, Mahan carried a more powerful torpedo armament. At the beginning of World War II, these destroyers were modernized with several automatic AA guns to fight enemy aircraft more efficiently.

Overview

Tier VII Mahan is the successor to the American destroyer Farragut, with further improvements to her firepower and survivability. She is the first tech-tree American destroyer that can fire torpedoes outside of her detection range. Her role in the game still focuses on her excellent main battery, but now torpedoes can become part of her offensive arsenal

Hull

Compared to Farragut, Mahan’s hull provides a welcome upgrade in terms of survivability, despite sharing similar traits. Both destroyers share similar maneuverability, with Mahan being slower by 1.5 knots. Her concealment is similarly bad, 0.1km worse than her predecessor and the second worst concealment for a Tier VII destroyer. With a fully upgraded hull and optimal captain skills, Mahan has 2,950 more hit-points than her predecessor for a maximum hit-point value of 16,550, placing her in the middle of the pack for a Tier VII destroyer. Still, her overall survivability is mediocre at best, as her relatively poor concealment allows the majority of destroyers in her matchmaking bracket to outspot her.

Firepower

Mahan takes Farragut's excellent guns and continues to refine them. Her main battery reload is reduced by 0.7 seconds, giving her some of the fastest-firing guns for a Tier VII destroyer at 3.3 seconds. This substantial increase in firepower allows Mahan to have the highest and second highest damage per minute values at the tier for her high explosive and armor piercing rounds respectively. Mahan’s guns are about as good as it gets until captains unlock Gearing, as Benson and Fletcher share essentially the same guns and shells. As with her predecessors, Mahan’s shells suffer from poor ballistics and fire chance. Despite the worst in tier fire chance, Mahan still has above-average firestarting potential due to her sheer volume of fire.

Mahan is an important step in the evolution of American destroyers, beginning their transition from gun boats to torpedo boats. She is the first tech tree American destroyer to have a torpedo range exceeding her detection range. With her upgraded torpedoes, she can launch torpedoes 9.2km away and 2.5km farther than her detection range. Although her torpedoes are some of the slowest and least hard hitting at Tier VII, the addition of long-ranged torpedoes is a welcome upgrade to her arsenal as it gives her more ways for her to deal damage.

Consumables

As with other American destroyers, Mahan has access to a smoke screen with a 30 second dispersion time and almost 2 minute action time. She can utilize the Smoke Generator  to create mobile cover and fire at enemies with her guns, or lay down cover for allied ships. Just like other American destroyers from Tier V to X, Mahan can choose between Engine Boost  and Defensive AA Fire . Captains should take Engine Boost  over Defensive AA Fire , as Mahan’s anti-aircraft battery is not good enough to take down a determined carrier strike. Engine Boost  allows captains to quickly reposition around the map while increasing her acceleration rate and top speed.

Gameplay

Mahan’s gameplay revolves around her excellent main battery, now with her torpedoes being a secondary weapon. At the start of the match, captains should move near caps with the presence of allied ships in order to spot for the team. It is inadvisable to sail into caps at the start of the game, as Mahan’s poor concealment ensures that most enemy destroyers will outspot her. Ideally, let an allied destroyer contest the cap, and support them with gunfire and torpedo attacks from a distance. With the addition of her long range torpedoes, captains have the option to conduct torpedo attacks from stealth without the need to open fire with her guns. This is a great way to kill time while her smoke is on cooldown. Utilize these tools in order to push off enemies and to secure flanks. Once a flank is secured, start rotating to other objectives and whittle down enemies with her artillery and torpedos. Keep an eye out for unspotted enemy destroyers, as they have the potential to drop torpedoes into the smoke of unsuspecting captains.

Overall, Mahan is a definite upgrade from Farragut and a solid Tier VII destroyer.

Pros:

Extremely high rate of fire
Extremely high HE and AP damage per minute values
Above average fire-starting potential
Long duration smoke
Fast turret traverse
Long range torpedos
Fastest rudder shift time and small turning radius in tier

Cons:

Floaty shell arcs makes hitting targets at long range difficult
Worst high-explosive shell fire chance for its tier (5%)
Torpedos are some of the slowest and weakest at its tier
AA will not stop a determined airstrike
Second worst concealment values for a tier VII destroyer

Research

Availability of researchable upgrades for Mahan is as follows:

Hull: Upgrade to Hull (B) for more hit-points and better rudder shift time. Progression to Benson is also unlocked with this upgrade.
Torpedoes: The Mk 15 mod.0 torpedoes travel 10 knots slower and do slightly less damage than the stock Mk 12 torpedoes, but have far more range.
Gun Fire Control System: Upgrade to the Mk 7 mod.2 for a 10% increase in main battery range.

As a gunboat destroyer, it is crucial that captains maximize ship health pool before anything else; this makes Hull (B) the first place to spend XP for upgrades. The Mk 15 torpedoes are a highly recommended upgrade, as it allows captains to utilize Mahan’s torpedoes without being detected. Finally, the upgraded Mk 7 fire control system is a welcome upgrade to extend the reach of the ship’s excellent main battery.

Optimal Configuration

Upgrades

Slot 1: Main Armaments Modification 1
Slot 2: Engine Room Protection or Engine Boost Modification 1
Slot 3: Aiming Systems Modification 1
Slot 4: Propulsion Modification 1

There isn’t much variety when it comes to optimal upgrades for the Mahan, as the ship is primarily locked into a gun-focused role. For the first slot, Main Armaments Modifications 1 is vital in order to keep the ship’s artillery and torpedoes from getting knocked out during the heat of battle. For slot 2, Captains can choose between Engine Room Protection or Engine Boost Mod 1 in order to have better protected engines and rudder, or a longer lasting Engine Boost. Being an artillery focused ship, Aiming Systems Mod 1 is an easy pick for slot 3, as Mahan’s torpedoes are too slow to reap the benefits of torpedo upgrades. Finally, Propulsion Mod 1 is the best upgrade for slot 4 as it greatly benefits the ship’s mobility while positioning around the map.

Commander Skills

Preventative Maintenance at Level 1 and Last Stand at Level 2 are easy recommendations for Mahan commanders. Both are crucial for any destroyer, as they reduce the probability and severity of engine or rudder failure. Losing steering or engine power during the heat of battle is likely to cost captains their ship, so it is imperative that they are protected.

Level 3 offers a number of good options. Survivability Expert is an easy pick, buffing Mahan’s health pool by 20%. Main Battery & AA Specialist and Adrenaline Rush are recommended for captains looking to get more damage out of their main battery. Superintendent is a strong choice if captains often fire from the cover of smoke. Fill the Tubes is valuable for captains looking to get more value from her torpedo battery. Inertia Fuse for HE Shells is incidentally useful, allowing Mahan's main battery to deal direct damage to same tier cruisers and battleships at the price of cutting fire chance by half.

Concealment Expert is recommended as the first Level 4 skill as it helps to cut down on Mahan’s poor base concealment. Fearless Brawler can replace Main Battery & AA Specialist if captains want to min-max their firepower. There is risk involved, as captains need to put their ship into potential danger in order to utilize the skill.
