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.

Player Opinion

Performance

Mahan is a fairly well-rounded destroyer by the standards of the class. She is the first American destroyer to have the capability to fire torpedoes from beyond her detection range — via the upgraded torpedoes she has access to upon equipping Hull (B) — as well as sporting a solid pool of hit points and fast firing guns that turn quickly.

Overall, Mahan is good at almost anything her enemies can throw at her. She is able to defend herself from enemy destroyers adequately; even more so once she gains additional hit points from upgrading to Hull (B). Her upgraded torpedoes are somewhat slow, but hit decently hard and can be fired from stealth. One thing of note about her torpedo launchers: she has one port, one starboard, and one centerline. This allows her to put a very respectable eight fish into the water on either side; however, many opponents forget about the launcher on the opposite side of the ship. It can make for a nasty surprise at close range if they believe that she's launched all of the torpedoes she had loaded.

Mahan’s primary weakness is her large detection range. Lacking access to Upgrade Slot 5, there is little that Mahan can do for her large detection radius other than spend commander skill points on Concealment Expert; even then, she remains one of the easiest Tier VII destroyers to spot.

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

Pros:

Fast turret rotation.
Outstanding main battery rate of fire.
Three torpedo tube launchers provide additional flexibility and will frequently catch opponents off-guard.
Long range torpedoes reach out to 9.2 km, making her the first American destroyer capable of firing torpedoes from beyond her detection range.
Fairly good AA defense.
Has access to the Defensive AA Fire () consumable.

Cons:

Very weak armor.
Large silhouette and a fairly large detection range.
Shorter main battery range compared to Farragut.
One of the slowest Tier VII destroyers at 35 knots.

Research

Availability of researchable upgrades for Mahan is as follows:

Hull: Upgrade to Hull (B) for additional health and improved rudder shift time; researching Hull (B) unlocks progression to Benson.
Torpedoes: The Mk15 mod. 0 torpedoes don't hit quite as hard and also travel slower, but they have far more range than her stock fish. Hull (B) must be equipped before they can be installed.
Gun Fire Control System: Upgrade to Mk7 mod. 2 for an extra 10% range on the main battery.

Hull (B) is the best place to invest early gains in Mahan; the additional hit points will increase her survivability immeasurably. The Torpedo upgrade is the next best place to spend experience gains; pick up the Fire Control System upgrade last.

Optimal Configuration

Upgrades

Slot 1: Main Armaments Modification 1 ()
Slot 2: Engine Room Protection ()
Slot 3: Aiming Systems Modification 1 ()
Slot 4: Propulsion Modification 1 ()

Upgrade options are pretty thin on the ground for Mahan. Main Armaments Modification 1 is the best choice for Slot 1. Slot 3 is fairly well restricted to Aiming Systems Modification 1; AA Guns Modification 1 () is not recommended given how anemic Mahan’s suite of anti-aircraft guns is.

Commander Skills

Level 1's best choice is Preventative Maintenance, as it reduces the chance of Mahan having her engine or rudder knocked out while under heavy fire. Last Stand is the best of the lot at Level 2; Mahan captains will find themselves under enemy fire frequently, and losing her engine is the worst possible module knockout she can suffer. Concealment Expert is clearly the best option at Level 4.

Level 3 offers a ton of great skill choices: Basic Firing Training improves Mahan’s abysmal anti-aircraft DPS as well as improving the rate of fire of her main battery guns; Survivability Expert adds more than 17% extra health; Vigilance allows her to better screen her allies from enemy torpeodes; Superintendent provides extra charges of valuable consumables; Demolition Expert increases the damage potency of her main battery. None of these are bad choices, but Survivability Expert should be the first one chosen. A dead Mahan does no damage, after all.

Consumables

Mahan can equip the following consumables:

Slot 1: Damage Control Party ()
Slot 2: Smoke Generator ()
Slot 3: Engine Boost () or Defensive AA Fire ()

Camouflage

Type 1, 2, or 5 camouflage can be equipped for credits; Types 1 or 5 are recommended at a minimum to reduce detectibility range.

Players who wish to spend doubloons can equip Mahan with Type 17 camouflage that lowers her detection radius, reduces the accuracy of incoming shells, reduces her repair costs, and increases the amount of experience she earns.

Signals

Equipping Sierra Mike () is an excellent way to help make up for Mahan’s deficiency in maximum speed. Captains should also consider Victor Lima () and India X-Ray () signals to increase the fire chance of her main battery shells, though they should be paired with a Juliet Charlie () to ensure that Mahan doesn't detonate under enemy fire.
