Cachalot — American Tier VI submarine.

The Cachalot-class submarine project was influenced by the restrictions of the London Naval Treaty and the characteristics of the German U-135 submarine. Subsequently, the Cachalot class was used as the basis for all American submarine designs of World War II. It was for the first time in the history of the U.S. Navy that welding was so widely used in submarine construction. USS Cachalot caught the start of World War II in Pearl Harbor. The submarine carried out three combat missions, having damaged a Japanese tanker.

Player Opinion



Cachalot is the Tier VI tech tree submarine in the American submarine branch. As an introductory submarine, she is only equipped with homing torpedoes, and has access to Enhanced Rudder GearsIncreases dive and ascent speed and reduces diving plane shift time..


Cachalot’s survivability is decent, with an HP pool of 14,000. Her armor is nonexistent, with her entire hull covered in 16mm. Players should be careful not to be spotted on the surface for extended periods of time, as she will suffer heavy damage.

Cachalot’s maneuverability helps her survive in battle. Her 430 m turning radius and 4.9-second rudder shift are both good, which aid in dodging depth charges. Conversely, her 6.4km concealment is quite high for a submarine, and means many destroyers in her matchmaking spread will be able to spot her in return.

She has a 27 knot top speed on the surface, and a 13 knot underwater speed. While her surface speed is average, her underwater speed is slow. This poor underwater speed means she is not fast enough to outrun destroyers, and her hull can be vulnerable to depth charges. Careful positioning is vital in order to not be stuck in bad situations where her speed will not bail her out.

Cachalot’s Dive Capacity recharge and depletion rate are standard for her tier, at 1 unit/second each. At 170 units, her Dive Capacity allows her to stay underwater for almost 3 minutes. Cachalot has no other ways of increasing her time underwater besides surfacing, which is not always possible to do safely.


Cachalot’s sonar is a helpful tool for dealing effective damage. The velocity is good at 600 m/s, and has a 10 km range with a 7.5s reload time. Double pings last for 50 seconds, which allows ample time for homing torpedoes to arrive.

Homing Torpedoes

Cachalot’s homing torpedoes allow for long range torpedo attacks. They have a range of 10km, deal a maximum of 7,833 damage, travel very fast at 86 knots, and have a 31.5% chance of flooding. While her homing torpedoes are good at long range, their fast speed and short arming distance also allow them to be used at close ranges against small and agile targets, especially when shotgunning. Shotgunning is the act of closing distance to a target (around 2-3km) while undetected and launching torpedoes at close range, often heavily damaging or destroying low-health ships. Due to having 4 bow torpedo tubes, shotgun attacks with homing torpedoes can deal respectable damage, and can kill low health cruisers and destroyers with her maximum alpha strike of 31,332 damage. Cachalot also has 2 rear torpedo launchers, which can be used after diving below targets and repeating the shotgun with rear launchers, for an alpha strike of 15,666 damage.

The torpedoes have a fast reload of 42 seconds. However, as Cachalot is an American submarine, she only reloads 2 bow and 2 stern torpedo tubes at a time, with the other torpedoes waiting to be reloaded after the previous 4 are finished.


Cachalot has a standard Damage Control Party, with only three charges stock, and a long 21-second duration time. This makes her relatively safe from module incapacitations and damage over time effects, as long as players can go undetected within the 21-second period. Players should be careful not to exhaust their limited charges, or they will rapidly lose HP to flood and fire damage.

Her Hydrophone is useful for tracking the location of surface ships while underwater. As Cachalot has higher concealment than most destroyers, the hydrophone is useful for gauging when it is safe to surface and recharge dive capacity. It lasts 30 seconds, has a long 8km range, and a 60-second reload time.

Cachalot’s Submarine Surveillance aids her in detecting enemy submarines, but has a short range of 6km. This can be a considerable downside when enemy subs with a longer range spot her (like U-69 with her 9km Surveillance), and Cachalot cannot spot them back.

As an American submarine, Cachalot gets access to the Enhanced Rudder Gears consumable, which reduces diving plane shift time by 20% and increases her maximum dive and ascend speed by 20%. This allows Cachalot to change depth quickly, rising to surface level quickly during attacks or diving faster to avoid detection.


Cachalot is limited by only having homing torpedoes, but serves as the introduction to the more damage oriented play style of the American submarines. She features an increased alpha strike and stronger overall damage capabilities with forward and rear torpedo tubes, at the expense of mediocre concealment, Dive Capacity, and information consumables.

Cachalot is best played at range, and in an area where she can use all 6 torpedo tubes with ease. Open areas that allow players to circle around while continually torpedoing targets will bring the best results in terms of damage. The fast reload and speed of the homing torpedoes allows Cachalot to harass enemy ships with constant pings and torpedoes. It is important to note that multiple pings in short succession will give away the approximate location of the player, and homing torpedoes are less effective against targets that are turned away or have their Damage Control Party available. To ensure survivability, it is recommended to minimize being spotted or blind-dropped by ASW planes.

Cachalot can still be played as a shotgun submarine, albeit at higher risk of dying. Her homing torpedoes have a good alpha strike, allowing her to deal devastating damage to unaware targets. However, the irregular reload of the torpedoes, mediocre surface concealment, and lower Dive Capacity reserve mean mistakes with managing battery reserves can lead to a quick trip back to port.

When closing the distance to shotgun targets, players should primarily approach battleships and cruisers. Once at around 6 km, players should dive to periscope depth and further close distance. At around 2-3 km, her torpedoes will arm and deal high damage to targets. Thus, players should quickly launch all torpedoes before proximity detection (2km) and dive quickly to avoid detection. Homing torpedoes are effective for shotgunning as they have both fast speed and lower arming distance. Players can also ping destroyers at close range, as the Homing Shutoff Distance is short for destroyers (200-400m). Cachalot having 4 torpedoes on her bow makes shotgun attacks crippling. Her 2 rear torpedo tubes can be used as a follow up attack after diving below and going behind targets.

Against enemy submarines, her long Damage Control Party duration can assist in denying homing torpedoes for the duration and allows Cachalot to get the first strike with fast homing torpedoes. However, the short range Submarine Surveillance can be detrimental against other submarines.

Cachalot is an entry level offense-oriented submarine, and her playstyle mainly involves pumping torpedoes into enemy ships from a distance. Her strengths and weaknesses are shown through the emphasis on torpedo damage and reload, while sacrificing utility and survivability,

  • Homing torpedoes with good range and fast sonar ping velocity
  • Fast torpedo tube reload
  • 4 torpedo tubes on the bow, 2 on the stern
