Partials/Equipment Type

Main Gun

 * Main equipment used to increase shelling Firepower . Also increases Anti-air stat.
 * Main Guns with green icon give a better anti-air bonus but generally sacrifice firepower.
 * Types of guns based on caliber and which ships can equip them:
 * Small Caliber Gun - Destroyer, Light Cruiser, Torpedo Cruiser, Seaplane Tender, Amphibious Assault Ship, Repair Ship, Submarine Tender
 * Medium Caliber Gun - Light Cruiser, Torpedo Cruiser, Heavy Cruiser, Aviation Cruiser, Battleship, Aviation Battleship
 * Large Caliber Gun - Battleship, Aviation Battleship, Fast Battleship


 * For Large Caliber Guns, 2014/7/28 update 1 2 introduced the Overweight Penalty and Fit Gun Bonus. When equipping a gun "fit" to battleship class, there will be an increase in accuracy. Inversely, when equipping multiple guns that are "overweight" for battleship class, there will be a decrease in accuracy.
 * Influences double attack/cut-in attack for artillery spotting and night battle.

Secondary Gun

 * Support equipment used to increase shelling Firepower . Gives Accuracy bonus.
 * Can be equipped by carriers, light cruisers and other large ships.
 * Influences double attack/cut-in attack for artillery spotting and night battle, but in a different way from main guns. Cannot trigger cut-ins when used alone; main guns must also be equipped. If day battle firepower is less important that night battle firepower or if artillery spotting cannot be done, then secondary guns can be used.
 * Similar to Main Guns, Secondary Guns with green icon have higher anti-air bonus but sacrifice firepower.

Torpedo

 * Equipment that increases Torpedo stat for torpedo phases of battle.
 * Can be equipped by Destroyer, Light Cruiser, Torpedo Cruiser, Heavy Cruiser, Aviation Cruiser, Submarine, and Aircraft-Carrying Submarine. Bismarck drei can also equip torpedoes.
 * Influences night cut-in attacks. Destroyers and other small ships have a chance to deal huge damage to enemy ships.
 * Ships cannot participate in day torpedo phases at moderate damage, though can still attack at night. At heavy damage, can participate in neither and torpedo is useless.
 * There is a Submarine Torpedo 53cm Submarine Bow Torpedo Mount (8 tubes) that's exclusively for Submarine and Aircraft-Carrying Submarine only.
 * Adding any disables double attacks, allowing cut-ins only. Consider using on high luck ships.

Carrier-Based Fighter Plane (Fighter)

 * Air Superiority fighter for Aircraft Carriers, Light Aircraft Carriers, and Amphibious Assault Ships. These shoot down other planes in Fighter Combat stage to establish Air Superiority/Supremacy.
 * Each planes contribute to fleet defense, plane count decreases after a battle if shot down, decreasing fleet AA stat accordingly.
 * If you get Air Superiority/Supremacy, your ships will take less damage from enemy planes and your planes can attack enemy ships better. Also, the number of your own planes shot down will decrease so less bauxite will be consumed when resupplying. Air superiority also enables Artillery Spotting (see Combat) which increases the damage done by your Cruisers and Battleships.

Carrier-Based Dive Bomber (Dive Bomber)

 * Aircraft for Aircraft Carriers (CV, CVL). Attacks enemy ships by dive bombing.
 * Aircraft Carrier, Light Aircraft Carrier needs to be equipped with at least one dive bomber or torpedo bomber to participate in shelling phase.
 * Unlike torpedo bombers, damage dealt during Aerial Combat is consistent.
 * Adds more damage during shelling phase, when compared with Torpedo Bombers.
 * Has anti-submarine stat . When equipped on Light Aircraft Carrier, attacks on Submarines is possible.
 * Some planes have Line of Sight stat.
 * If you lose air superiority, these will be shot down. Amount lost doesn't seem different from Torpedo Bomber.
 * If plane has anti-air stat, it will participate in fighter combat (fighter-bomber)
 * Cannot attack Installation type bosses.
 * Become useless if the carrier become moderate damage (except for Armored Carriers)

Carrier-Based Torpedo Bomber (Torpedo Bomber)

 * Aircraft for Aircraft Carriers (CV,CVL). Attacks enemy ships with torpedoes.
 * Aircraft Carrier, Light Aircraft Carrier needs to be equipped with at least one dive bomber or torpedo bomber to participate in shelling phase.
 * Damage dealt during Aerial Combat is either 80% or 150%. Because of this, torpedo bomber damage is inconsistent: sometimes weak, sometimes strong.
 * Added damage during shelling phase is lower, when compared with Dive Bombers.
 * But, when comparing the top craftable Ryuusei Kai and Suisei M12A, they are almost the same. (Ryuusei Kai: 19.5 | Suisei M12A: 20)
 * Has anti-submarine stat. When equipped on Light Aircraft Carrier, attacks on Submarines is possible. Some models have slightly higher stat than Dive Bombers.
 * Has Line of Sight stat . Can contribute to enemy detection.
 * Can trigger Contact which increases the damage of your Dive Bombers and Torpedo Bombers, but very low trigger chance.
 * If you lose air superiority, these will be shot down. Amount lost doesn't seem different from Dive Bomber.
 * If plane has anti-air stat, it will participate in fighter combat.
 * Japanese name 艦上攻撃機 literally means Carrier-Based Attack Plane so some people call them that.
 * Become useless if the carrier become moderate damage (except for Armored Carriers)

Carrier-Based Reconnaissance Plane (Recon Plane)

 * Aircraft for Aircraft Carriers. Detects enemy ships.
 * Saiun prevents T-cross disadvantage.
 * Can trigger Contact which increases the damage of your Dive Bombers and Torpedo Bombers.
 * Bonus damage from Contact depends on Accuracy stat of plane.
 * Saiun gives 17% and Type 2 Recon gives 20% bonus.

Reconnaissance Seaplane (Recon Seaplane)

 * Aircraft that can land on water, used by ships other than aircraft carriers.
 * Can be equipped by Battleship, Aviation Battleship, Heavy Cruiser, Aviation Cruiser, Light Cruiser, Seaplane Tender, Aircraft-Carrying Submarine, Submarine Tender.
 * Helps in detecting the enemy . Can trigger Contact during Aerial Phase.
 * Some Light Cruisers (Tenryuu-class, Ooi, Kitakami, Yuubari, Isuzu Kai-2) have zero plane count and equipping seaplane will have no effect.
 * Recon Seaplane have anti-submarine stat but cannot attack submarines without seaplane bombers.
 * If this is equipped and you have Air Superiority then Day Battle Double Attack/Cut-in (Artillery Spotting) can trigger. (requires at least one seaplane left)


 * Even though this is only for recon, when your detection stat is low or when enemy has strong Fighter Power, planes may not return and be lost. (same applies to carrier based aircraft and seaplane bombers)

Seaplane Bomber

 * Aircraft that can land on water, used by ships other than aircraft carriers.
 * Can be equipped by Aviation Battleship, Aviation Cruiser, Seaplane Tender, Aircraft-Carrying Submarine.
 * At the start of battle helps in detection.

 * Zuiun has Anti-Air stat and, similar to Fighters, can participate in Fighter Combat Stage.
 * Cannot trigger Contact unlike Recon Seaplane.
 * When equipped by Aviation Battleship, Aviation Cruiser, or Seaplane Tender, can attack submarines, but only during day battle.
 * Can enable Artillery Spotting like Recon Seaplane.
 * Can enable Aerial Superiority.

Night Reconnaissance Seaplane (Night Scout)

 * Similar to Recon Seaplane, but has additional effects during night battle.
 * Can trigger Night Contact which boosts your ships' critical rate.
 * Similar to Contact, Night Contact will trigger only with Air Superiority during the day, or if the battle begins at night.
 * Can trigger Artillery spotting during day battle but with lower effect than normal recon planes.

Radar

 * RAdio Detection And Ranging acronym. Uses radio waves to detect and locate enemies from afar.
 * Small Radar can be equipped by all surface ships but Large Radar cannot be equipped by Destroyer, Amphibious Assault Ship, Repair Ship, Submarine Tender. Cannot be equipped by Submarines or Aircraft-Carrying Submarines
 * Reduces the effect of Maelstrom. Reduction is dependent on the number of ships carrying a Radar and maxes out with 3 Radar-carrying ships.
 * There are Air Radar and Surface Radar. Air Radar have Anti-air stat, Surface Radar have higher Detection and Accuracy  bonuses. Air Radar increases the rate of Anti-Air Cut-In attacks, while Surface Radar increases the rate of Cut-In bombardment attacks from the main guns.
 * Differences between Small and Large Radars, other than being equippable by different ships, are unknown.

Machinery

 * Increases ship's evasion.
 * Can be equipped by all ships.
 * Evasion rate is increased by a small amount in exchange for limited equipment slots. Please think carefully when using.

Shell

 * Affects artillery spotting cut-in, Does not affect night double attack/cut-in.
 * Originally could only be equipped by Nagato-class, Yamato-class and Aviation Battleships; but after the 2014/7/28 update, can also be equipped by Kongou-class and Bismarck.
 * After the 2014/10/10 update, when Armor Piercing Shell and Large Caliber Guns are equipped together, daytime shelling damage and accuracy are increased against enemies with thick armor and installation type bosses.
 * Type 1 AP Shell has higher stats than Type 91 shell, but only 2 can be obtained from quest. As of the January 23rd update, more Type 1 shell can be obtained by upgrading through Akashi's Improvement Arsenal.
 * AA Shells (Type 3 Shell)
 * Can be equipped by Heavy Cruiser, Aviation Cruiser, Battleship and Aviation Battleship.
 * Increases Anti-air stat.
 * Has a large fleet defense bonus, currently the strongest craftable anti-air equipment.
 * Very effective against Installation type bosses. Damage formula becomes Firepower×2.5.

Machine Gun and Rocket Launcher

 * Used against enemy attacks from the air. Launches a barrage to deter enemy planes.
 * Can be equipped by all surface ships.
 * Increases fleet air defense but only by a negligible amount.
 * Currently, there are few reasons to equip them due to limited equipment slots.
 * If you don't want to affect your double attack/cut-in combination and have empty slots left, can be considered as slot filler.
 * Machine Guns add +1 evade stat, which can be useful for low-level Admirals prior to obtaining sufficient numbers of turbines and boilers for the fleet. For instance, on map 1-6, equipping these in bulk on the non-flagship destroyers/light cruisers reduces the chance the other ships get hit by the elite submarines' opening strikes, while ASW gear on the flagship guarantees it the MVP morale/xp bonus.

Midget Submarine

 * Small special-purpose submarine that comes close to enemy ships and fires torpedoes.
 * Can be equipped by Torpedo Cruiser, Seaplane Tender, Abukuma Kai-ni and Submarine.
 * Currently, only the Type A Ko-hyoteki is in this category.
 * Allows Torpedo Cruiser, Seaplane Tender, Abukuma Kai-ni and Submarine with level less than 10 to participate in Opening Torpedo Salvo.
 * Does not count as a torpedo so it does not affect night cut-in.
