 +===Battle Tiers===
 +The '''battle tier''' (battle level) is the highest tier of the ships in the battle. Each ship has a maximal permitted battle tier of the battles she can be sent to, so this is the highest tier of the ships she may encounter in battle (unless she is in a division with a higher tier ship).
  
?Each ship has a certain combat tier assigned to it. It determines the maximum level of enemy and ally ships that can be encountered in the battle.+The maximal permitted battle tier is:
 +*I for Tier I ships<ref name="0.5.10">[https://worldofwarships.eu/en/news/game-updates/update-0510-release/ Introducing Update 0.5.10]</ref>
 +*"Tier + 1" for Tier II-IV ships<ref name="0.5.9">[https://worldofwarships.eu/en/news/game-updates/update-059-release/ Introducing Update 0.5.9]</ref>
 +*"Tier + 2" for Tier V-VIII ships<ref name="0.5.9" />
 +*X for Tier IX-X ships<ref name="0.5.9" />
  
?The information below is current as of patch 0.5.9.0.+This leads to the following tables:

 +Example: A Tier VI cruiser either gets into a Tier VI battle, a Tier VII battle or a Tier VIII battle. In a Tier VI battle, it can encounter Tier V and Tier VI ships. In a Tier VII battle, it can encounter ships from Tiers V to VII. In a Tier VIII battle, it can encounter ships from Tiers VI to VIII.

?* As of patch 0.5.8.0, matchmaker will make matches with an equal amount of top tier Battleships and Cruisers and with the same amount of Carriers of the same tier.+===Other restrictions in Random Battles===
?* As of patch 0.5.9.0, matchmaker will limit aircraft carriers to one per team in battles where the top tier ship is of Tier VIII, IX, or X. +Explanation of "'''soft limit'''" / "'''soft rule'''": the matchmaker tries to fulfill it but ignores it when players have to wait too long for a battle.
?* As of patch 0.5.9.0, matchmaker will once again attempt to uniformly distribute ships of different nations between the teams. (Example: If two Soviet ''Gnevny'' destroyers and two Japanese ''Minekaze'' destroyers are present, the matchmaker will attempt to put one destroyer of each nation on each team.)+

 +**Soft rule: Teams are mirrored by ship types (cruiser etc.) and tiers. This means that for every ship type and tier, both teams have the same number of ships of that type and tier.
 +*There are soft restrictions on the minimum number of ships allowed that are two tiers lower than the battle tier, and also on the maximum number of ships of the highest tier in the battle<ref name="0.9.3.1">[https://worldofwarships.eu/en/news/game-guides/matchmaking-the-basics-making-teams/ Matchmaking: The Basics Making Teams (Update 0.9.3.1)]</ref>.

?Divisions of up to three ships can be created. Currently divisions can only have one carrier (and a random team can have no more than two Carriers). +=== Low-Tier (I-V) Matchmaking for Random Battles ===
 +<ref>[[Ship:Update 0.9.6#Low-Tier_Matchmaker_Changes|Update 0.9.6]]</ref>
  
?Matchmaker treats all the ships in the division as having the highest present tier; so if, for example, a tier 3 and a tier 7 ships division together, matchmaker views both of them as tier seven ships and will assign them to battle accordingly. For that reason, it is never a good reason to division with ships that vastly differ in tiers (so-called "fail divisions") -- you will weaken your team, and draw the wrath of your teammates.+In Tier I-V battles, if the waiting time spent by the first player in the queue exceeds '''3 minutes''', the remaining places in the teams will be occupied by '''bots'''.
  
?== Ship Performance Factors ==+* In Tier I–IV battles, bots are equal in strength to the bots in Co-op Battles.
?For each ship there are five main performance factors that provide a basis for comparison of any one ship against another in game. There are an additional two performance factors for those ships which are armed with aircraft or torpedoes. These performance factors are expressed on a relative scale of 0 (worst) to 100 (best). Each performance factor is calculated or influence from a combination of other individual factors as follows:+* In Tier V battles, bots have improved AI and fight at the skill level of those in Operations.
  
?* '''Survivability''' is a measure of the ship's ability to take damage and keep fighting. Its mainly all about hit points. The T10 BB's IJN [[Ship:Yamato|Yamato]] and the USA [[Ship:Montana|Montana]] share top Survivability factor in-game with 100. The GER T1 PB [[Ship:Hermelin|Hermelin]] and the USSR T1 PB [[Ship:Orlan|Orlan]] share the worst with 9.+==== The Matchmaker for Newcomers ====
?* +
?* '''Artillery''' is a measure of the ship's firepower with its main and secondary guns. The main battery firing range in kilometers and the number, type, and positions of the main battery and the secondary armament guns contribute to this factor. The the USA T10 BB [[Ship:Montana|Montana]] has the top Artillery factor in-game of 94. The IJN T2 DD [[Ship:Tachibana|Tachibana]] has the worst with 1.+
?* +
?* '''AA Guns''' is a measure of the ship's anti-aircraft defenses and its ability to defend itself from air attacks. The number and caliber of the on-board AA guns contribute to this factor. The USA T10 CA [[Ship:Des Moines|Des Moines]] has the best AA Guns factor in-game of 90. The USA T4 CV [[Ship:Langley|Langley]], the IJN T4 BB [[ship:Myogi|Myogi]], the IJN T3 BB [[Ship:Kawachi|Kawachi]], the USA T3 BB [[Ship:South Carolina|South Carolina]], the IJN T2 BB [[Ship:Mikasa|Mikasa]], the IJN T2 DD [[Ship:Tachibana|Tachibana]], the USSR T2 CL [[Ship:Diana|Diana]] and the USA T2 CL [[Ship:Chester|Chester]] have the worst because they are not armed with any AA Guns.+
?* +
?* '''Maneuverability''' factor is a measure of the ship's ability to maneuver, make turns, and maintain speed while turning. Three other factors affect Maneuverability, the ship's "Maximum Speed" in knots, its "Turning Circle Radius" in meters, and its "Rudder Shift Time" in seconds. The IJN T5 DD [[Ship:Minekaze|Minekaze]] has the best Maneuverability factor in-game of 95. The USA T4 CV [[Ship:Langley|Langley]] has the worst at 7.+
?* +
?* '''Concealment''' factor is a measure of the ship's ability to remain undetected by the enemy. The Concealment factor is a calculated parameter influenced by the ship's "Surface Detectability Range" and an "Air Detectability Range", each are also specified and expressed in kilometers. The IJN T2 DD [[ship:Umikaze|Umikaze]] has the best Concealment factor in-game of 97. The USA T10 CV [[Ship:Midway|Midway]] has the worst at 5. The Type-1 Camouflage presumably further reduces the detectability range by enemy ships by 3%. +
?* +
?* '''Torpedoes''' is a measure of the torpedo capability of those ships which carry torpedoes. The number, type, and position of the torpedo tubes and the range of the torpedoes contribute to this factor. The IJN T10 DD [[Ship:Shimakaze|Shimakaze]] has the best Torpedo factor in-game of 60. The IJN T2 DD Umikaze and [[Ship:Tachibana|Tachibana]] have the worst rating which is 4. Those ships not armed with torpedoes have no Torpedo factor.+
?* +
?* '''Aircraft''' is a measure of the aircraft capability of those ships which carry aircraft. The total number of squadrons, number of planes, and the type and capabilities of each of the planes: fighter, dive-bomber, or torpedo-planes; determine the Aircraft factor. The USA T10 CV [[Ship:Midway|Midway]] has the best in-game Aircraft factor of 79. USA Cruisers beginning with T5 CL [[Ship:Omaha|Omaha]] and IJN Cruisers beginning with T4 [[Ship:Kuma|Kuma]] carry 1 to 3 fighter/recon aircraft. Only CVs have an Aircraft factor.+
  
?==Spotting Mechanics==+A newcomer is a player who has played at most 200 battles. ''World of Warships'' has a special queue for newcomers entering Random battle so they gain experience before moving on to general Random Battles. If any newcomers decide they are ready to fight with experienced players, they will be able to do that by playing Tier V+ ships:
 +* When playing a ship of Tier I–IV, a newcomer is put into the special queue for newcomers only.
 +* When playing a ship of Tier V or higher, a newcomer is put into the general Random queue.
 +* Players who have played more than 200 battles will always be placed in the general Random queue.
 +* If the waiting time spent by the first player in the queue exceeds 3 minutes, battles are possible where there is only one live player mirrored by a bot. In this case, the rest of the player’s team will be filled out with bots, and the opposing team will also be filled with bots, mirroring the player’s team in terms of ship tiers and types.
 +* A Division can be placed in the queue for newcomers only if all members meet the requirements above (not more than 200 battles, Tier I-IV ship).
  
?A ship is spotted when another enemy ship or aircraft gets close enough to detect it. This mainly involves two sets of values.+==== Bots in Non-Newcomer Random Battles ====
  
?The first set of values is '''Detection range,''' which is divided into two categories+* In Tier I–V Random Battles, bots will be added until complete teams are formed if the waiting time spent by the first player in the queue exceeds 3 minutes. A battle will only be matched if the general queue contains at least one pair of players playing ships of the same tier.
 +* If players have ships of different types, then after 3 minutes of waiting in the queue, they will be mirrored by bot ships of the same types and tiers, and the teams will be complemented with bots within the limits for ship types and tiers for this particular battle tier. It means each team will have the same number of bots.
 +* A visual notification about the maximum waiting time and possibility of matching bots to the battle is on the battle loading screen.
  
?*'''Surface Detectability Range:''' This is the range at which a ship will be detected by an enemy ship. A '''Line of Sight (LoS)''' is required between the spotting ship and the ship being spotted. A ship will not be spotted if there are no enemy ships within this range.+===Other restrictions in Co-op Battles===
?*'''Air Detectability Range:''' This is the range at which a ship will be detected by an enemy aircraft. This is usually shorter than the surface detectablity range. Unlike surface detection, catapult launched aircraft can spot enemy ships within 4 km of itself regardless of LoS, beyond that range they need LoS to the ship. Carrier based aircraft are not restricted by LoS at all when detecting enemy ships. +*The bot team mirrors the player team by type and tier.
 +*at most 4 battleships and 4 destroyers helmed by players<ref name="0.7.10.2" />.
 +*Bots may be added to the player team<ref name="0.7.0">[https://worldofwarships.eu/en/news/game-updates/dasha-in-training-070/ Dasha Presents Update 0.7.0.2]</ref>:
 +**cruiser rule: if cruisers are the most numerous type, a destroyer is added.
 +**destroyer rule: if destroyers are the most numerous type, a battleship is added.
 +**battleship rule: if battleships are the most numerous type, a cruiser is added.
 +**if two or more types are the most numerous, the rules are applied in the following order of priority: battleship rule, cruiser rule and destroyer rule.
 +**Any bot-driven ship matched into a battle may only be taken from the list of researchable ships, and its tier must equal the lowest tier brought to battle by a player, provided that the required type of ship is available at that tier.
 +**If there are no ships of the required type, the next ship type is selected in this order: battleship, cruiser, destroyer.
 +**Sometimes an aircraft carrier is added.
 +**Bots are added until there are nine players on each team.
  
?[[File:Cone_indicating render_and_view_range_in minimap.jpg|320px|thumb|Note that only the allied battleship is rendered while the other two ships outside the player's view range is not rendered]]+== Divisions ==
?The second set of values is '''View range,''' which is also doubles as a ship's render range. It is indicated by the outer limit of the grey cone on the player's minimap in battle. Any ship outside of this range can not be detected by the player, while any allied ships and spotted enemy ships outside of it will not be drawn on the player's screen but will be displayed on the player's minimap as outlined icons. In general, the taller the ship the higher its view range will be. Therefore battleships tend to have very long view ranges (in excess of over 20 km), while destroyers usually have shorter view ranges than other ship classes. +
  
?Aircraft carriers have unlimited view range, while aircraft (both catapult launched and carrier based) have a view range of 11 km. In most cases, view range has little impact on ship to ship detection, because it is usually far higher than the detectability range of the ships being spotted. The only time view range has any appreciable effect on ship to ship detection is when the spotting ship has a lower view range than the target's detectability range, such as a destroyer attempting to spot certain battleships. In these cases, the target is spotted not at its detectability range but at the moment it enters the view range of the spotting ship.+Divisions of up to three ships can be created. Currently divisions can only have one carrier. Divisions are restricted to a one tier spread<ref name="0.5.10" />. A division with a Tier VI ship, for example, could include ships of Tier V and Tier VI, or Tier VI and Tier VII. Tier V, VI, and VII ships are not allowed in the same division at the same time.
  
?{{clear}}+Previously, there were no restrictions on division tiers, leading to "fail divisions" of high tier ships (such as Tier IX or X) divisioned with low tier ships (Tier I or II).
?[[File:Diagram_showing_relationship_between_detection_range_and_view_range.png|352px|right]]+
?In the diagram to the right, assuming all ships are enemies to one another, the destroyer (pink) can detect the cruiser (orange) as the cruiser is within the destroyer's view range (pink dashed line) and the distance between the two ships is smaller than than the cruiser's detectability range (orange line). However, the destroyer can not detect the battleship (blue) even though the distance between them is smaller than the battleship's detectability range (blue line) because the battleship is outside of the destroyer's view range (pink dashed line).+
  
?The cruiser on the other hand can detect the battleship, as it is within the cruiser's view range and the distance between them is smaller than the battleship's detectability range, however the cruiser can not detect the destroyer even though it is within the cruiser's view range because the distance between them is larger than the DD's detectability range.+When placing divisions in a match, Match Maker will only consider the highest tier ship's Match Making tier range for purposes of tier placement. For example, a Tier 5's normal Match Making is +2/-1, so it will normally only see Tier 4 through Tier 7 ships in matches. Similarly, a Tier 6's normal Match Making is also +2/-1, so it will normally only see Tier 5 through Tier 8 ships in matches.
 +When divisioned with ships of the same tier, the division will see the normal Match Making for that tier. For example, a division of only Tier 5s will only see matches with Tier 4 to Tier 7 ships. A division of only Tier 6s will only see matches with ships from Tier 5 to Tier 8.
  
?The battleship can not detect either the destroyer or cruiser even though the battleship's view range encompasses both of them because their distance to the battleship is larger than their respective detectability range.+However, when a division is made up of ships of unequal tier, only the top tier ship's tier range will be considered. Thus, let us say the Tier 5 and Tier 6 above form a division. Match Maker will only consider the Tier 6's tier spread. The Tier 6 can see Tier 8 matches, so the Tier 5 in the division with it will now also be subject to seeing Tier 8 matches where it normally would only be able to see Tier 7s max. This results in an effective +3/-1 Match Making spread for the Tier 5 when divisioned with a Tier 6.
 +This is commonly called a "fail division" because this puts the lower tier ship in a battle tier they normally cannot see.
  
?If the destroyer and the battleship is on the same team while the cruiser is on the opposing team, the destroyer will spot the cruiser for the battleship and it will appear as a solid icon on the battleship's minimap and be rendered in its main view. If the destroyer and the cruiser is on the same team while the battleship is on the opposing team, the cruiser will spot the battleship for the destroyer but it will only appear as an outline in the destroyer's minimap and not rendered in its main view.+== Ship Performance Factors ==
?{{clear}}+For each ship there are seven performance factors that provide a basis for comparison of any one ship against another in game. These performance factors are expressed on a relative scale of 0 (worst) to 100 (best). Each performance factor is based on the ship's abilities. Note that these factors are just a basis for comparison, and can change based on what modules, upgrades, or captain skills the ship is equipped with.
  
?There are a few factors that can affect spotting:+* '''Survivability''' is a measure of the ship's ability to take damage and keep fighting. Its mainly all about hit points. The T10 BB's IJN [[Ship:Yamato|Yamato]], KMS [[Großer Kurfürst]], HMS [[Conqueror]], USS [[Ship:Montana|Montana]] and MN [[Republique]] share top Survivability factor in-game with 100. Many tier one ships share the worst, with 4.*
?*'''Firing main guns.''' This greatly increases a ship's detectability range for a duration of 20 seconds, allowing it to be spotted at a distance higher than the ship's base detectability range. In general, the bigger caliber of the main guns the bigger the increase will be. The value increased is different for both surface and air detection.+
  
?The detection formula is as follows:+* '''Artillery''' is a measure of the ship's firepower with its main and secondary guns. The main battery firing range in kilometers and the number, type, and positions of the main battery and the secondary armament guns contribute to this factor. The US T10 BB [[Ship:Montana|Montana]], IJN [[Yamato]] and UK T10 BB [[Conqueror]] have the top Artillery factor in-game of 94. Asides tier 1 ships, The IJN T2 DD [[Ship:Tachibana|Tachibana]] has the worst with 2.
?[caliber in mm] x 3 x 10 for visibility from ships+*
?[caliber in mm] x 2 x 10 for visibility from airplanes+* '''AA Guns''' is a measure of the ship's anti-aircraft defences and its ability to defend itself from air attacks. The number and caliber of the on-board AA guns contribute to this factor. The U.S T10 CL [[Ship:Worcester|Worcester]] has the best AA Guns factor in-game of 96. Many ships, such as the US premium T4 BB [[ship:Arkansas_Beta|Arkansas Beta]], IJN premium T2 DD [[Ship:Tachibana|Tachibana]], Russian premium CA [[Oleg]] and KM T3 BB [[Nassau|Nassau's]] A hull have the worst - 0 - because they are not armed with any AA Guns.
?e.g. firing 203mm rifles will increase visibility from airplanes by 4060 meters.+*
 +* '''Maneuverability''' factor is a measure of the ship's ability to maneuver, make turns, and maintain speed while turning. Three other factors affect Maneuverability, the ship's "Maximum Speed" in knots, its "Turning Circle Radius" in meters, and its "Rudder Shift Time" in seconds. The IJN T5 DD [[Ship:Minekaze|Minekaze]] and Russian T5 DD [[Podvoisky]] share the best Maneuverability factor in-game - 95. The US T4 CV [[Ship:Langley|Langley]] has the worst at 7.
 +*
 +* '''Concealment''' factor is a measure of the ship's ability to remain undetected by the enemy. The Concealment factor is a calculated parameter influenced by the ship's "Surface Detectability Range" and an "Air Detectability Range", each are also specified and expressed in kilometers. The IJN T2 DD [[Ship:Tachibana|Tachibana]] and it's T10 cousin [[Ship:Shimakaze|Shimakaze]] has the best Concealment factor in-game of 98. The US T10 CV [[Ship:Midway|Midway]] has the worst at 5. Many camouflages, such as the Type-1 Camouflage further reduces the detectability range by sea of the ship it is mounted on by 3%.
 +*
 +* '''Torpedoes''' is a measure of the torpedo capability of those ships which carry torpedoes. The number, type, and position of the torpedo tubes and the range of the torpedoes contribute to this factor. The IJN T10 DD [[Ship:Shimakaze|Shimakaze]] has the best Torpedo factor in-game of 60. The IJN T2 DDs [[Ship:Umikaze|Umikaze]] and [[Ship:Tachibana|Tachibana]], as well as the USS [[Smith]] have the worst rating which is 4. Those ships not armed with torpedoes have no Torpedo factor.
 +*
 +* '''Aircraft''' is a measure of the aircraft capability of those ships which carry aircraft. The total number of squadrons, number of planes, and the type and capabilities of each of the planes: fighter, dive-bomber, or torpedo-planes; determine the Aircraft factor. The USA T10 CV [[Ship:Midway|Midway]] has the best in-game Aircraft factor of 86. Cruisers (beginning at T5 except the T4 IJN [[Ship:Kuma|Kuma]]), and Battleships of certain tiers, carry 1 to 3 fighter/recon aircraft. Battleships can only mount catapult fighters at tier 7 and up, with the exception of [[Dunkerque]]. Only CVs have an Aircraft factor.
  
?The patch 0.5.5 intends to change the visibility mechanics: if the ship was not spotted before the salvo, it will dissapear immediatly after firing, and won't have the 20 second visibility penalty+{{VideoYT|HJDMqqLyBek}}
? +{{#gw_breadcrumbs: Ship}}
?*'''Firing AA guns and secondary guns.''' AA guns and secondary guns that are actively firing also increases a ship's detectability range. The increase is 1.3 km by surface and 2 km by air. For secondary guns, much like with main caliber, the increase in visibility lasts for 20 seconds since the last shot.For AA guns, the increase is only aplied as long as they are actively firing. It is often recommended for Destroyers to switch off their AA guns so as to not reveal their position by firing at passing enemy aircraft, however this is only relevant if the ship has AA that is longer range than their detection range by air.+
  
?*'''Fires.''' A ship that is set on fire will have 3 km added to their detectability range (2 km by air) for as long as it's on fire. The increase does not stack with multiple fires.+==References==
? +<references />
?*'''Smoke screens.''' Smoke works by '''blocking LoS.''' If a ship is inside a smoke screen or have a smoke screen between it and all possible spotters, it can remain undetected even when there are enemy spotters within its detectability range. For air detection, smoke is considered as being at the same height as flying aircraft, therefore a catapult launched aircraft needs to be close to or over the smoke screen in order to detect any ships hiding beyond it. However, an aircraft can not detect a ship that is inside the smoke screen itself even if the aircraft is flying directly over the ship.+[[Category:World of Warships]]
? +[[Category:Rules pages]]
?*'''Engine Boost.''' Destroyers using this consumable to increase its speed and acceleration will have 0.2 km added to their detectability range for as long as they are accelerating or moving at top speed. The penalty is not applied if the ship is decelerating or comes to a stop while the consumable is still active. note: this is no longer the case as of patch 0.5+
? +
?*'''Proximity spotting.''' At 2 km ships will automatically detect each other regardless of LoS, making it possible for ships to be detected even if they are hiding inside a smoke screen or behind terrain. The consumable Hydroacoustic Search can extend this auto-spot range for a limited duration.+
? +
?*'''Upgrades, skills and camouflage.''' A ship's detectability range can be decreased by using certain upgrades, skills and camouflage. The bonuses from each of them can also stack together, so a Kagero (with base surface detectability range of 6.8 km) fully decked for concealment can have a surface detectability range of only 5.24 km.+
? +
?Launching torpedoes will not increase a ship's detectability range. Sailing slowly or stopping completely will not reduce a ship's detectability.+
? +
?Both catapult launched and carrier based aircraft have a detectability range as well, at 4 km for catapult launched aircraft and 8 km for carrier based aircraft. The distances are the same for both surface and air detection.+
? +
?Torpedoes are detected at different ranges according to its type, the values are the same for both surface and air detection. The consumable Hydroacoustic Search can help detect torpedoes by providing a flat proximity spotting range that is higher than the range the torpedoes are normally detected for a limited duration. Once a torpedo has been spotted, it will remain spotted for the duration of its run.+

Matchmaking (MM) for Random and Co-op Battles

Battle Tiers

The battle tier (battle level) is the highest tier of the ships in the battle. Each ship has a maximal permitted battle tier of the battles she can be sent to, so this is the highest tier of the ships she may encounter in battle (unless she is in a division with a higher tier ship).

The maximal permitted battle tier is:

  • I for Tier I ships[1]
  • "Tier + 1" for Tier II-IV ships[2]
  • "Tier + 2" for Tier V-VIII ships[2]
  • X for Tier IX-X ships[2]

This leads to the following tables:

Ship Tier Possible Battle Tiers
I II III IV V VI VII VIII IX X
I
II
III
IV
V
VI
VII
VIII
IX
X
Ship Tier Possible tiers of other ships in battles
I II III IV V VI VII VIII IX X
I
II
III
IV
V
VI
VII
VIII
IX
X

Example: A Tier VI cruiser either gets into a Tier VI battle, a Tier VII battle or a Tier VIII battle. In a Tier VI battle, it can encounter Tier V and Tier VI ships. In a Tier VII battle, it can encounter ships from Tiers V to VII. In a Tier VIII battle, it can encounter ships from Tiers VI to VIII.

Other restrictions

  • Both teams have the same number of ships.[3]
  • at most 2 aircraft carriers per team[4] (at most 3 in training battles)

Other restrictions in Random Battles

Explanation of "soft limit" / "soft rule": the matchmaker tries to fulfill it but ignores it when players have to wait too long for a battle.

  • Mirror Matchmaking: Dev Diaries: Mirror Matchmaking (Update 0.7.4, 2018-04-19)
    • Soft rule: Teams are mirrored by ship types (cruiser etc.) and tiers. This means that for every ship type and tier, both teams have the same number of ships of that type and tier.
  • There are soft restrictions on the minimum number of ships allowed that are two tiers lower than the battle tier, and also on the maximum number of ships of the highest tier in the battle[5].
  • If possible, ships of different nations are distributed between teams on an even basis.[5]
  • The matchmaker does not try to distribute identical ships evenly.
  • soft limit: at most 4 destroyers per team[6].
  • soft limit: at most 5 battleships per team[5].
  • Aircraft Carriers:
    • mirrored[7]. (For every tier, both teams have the same number of carriers.)
    • Battle Tier X: soft limit: at most 1 per team[8]
    • Battle Tiers VIII-IX: soft limit: at most 1 Tier VIII carrier per team[9].
  • There are upper limits on the percentages of battle tiers a ship will be sent to.[10]
  • "Understaffed" teams (11v11, 10v10, etc.) are possible[7]
  • There is a maximum difference of one division between opposing teams within a single battle.[5].
  • Top-tier ships are mirrored by type.[7]
  • Battleships whose tier is one less than the top tier are mirrored.[7]
  • One team has at most 1 battleship more than the other team.[7]
  • One team has at most 1 destroyer more than the other team.[7]
  • One team has at most 2 cruisers more than the other team.[7]

Low-Tier (I-V) Matchmaking for Random Battles

[11]

In Tier I-V battles, if the waiting time spent by the first player in the queue exceeds 3 minutes, the remaining places in the teams will be occupied by bots.

  • In Tier I–IV battles, bots are equal in strength to the bots in Co-op Battles.
  • In Tier V battles, bots have improved AI and fight at the skill level of those in Operations.

The Matchmaker for Newcomers

A newcomer is a player who has played at most 200 battles. World of Warships has a special queue for newcomers entering Random battle so they gain experience before moving on to general Random Battles. If any newcomers decide they are ready to fight with experienced players, they will be able to do that by playing Tier V+ ships:

  • When playing a ship of Tier I–IV, a newcomer is put into the special queue for newcomers only.
  • When playing a ship of Tier V or higher, a newcomer is put into the general Random queue.
  • Players who have played more than 200 battles will always be placed in the general Random queue.
  • If the waiting time spent by the first player in the queue exceeds 3 minutes, battles are possible where there is only one live player mirrored by a bot. In this case, the rest of the player’s team will be filled out with bots, and the opposing team will also be filled with bots, mirroring the player’s team in terms of ship tiers and types.
  • A Division can be placed in the queue for newcomers only if all members meet the requirements above (not more than 200 battles, Tier I-IV ship).

Bots in Non-Newcomer Random Battles

  • In Tier I–V Random Battles, bots will be added until complete teams are formed if the waiting time spent by the first player in the queue exceeds 3 minutes. A battle will only be matched if the general queue contains at least one pair of players playing ships of the same tier.
  • If players have ships of different types, then after 3 minutes of waiting in the queue, they will be mirrored by bot ships of the same types and tiers, and the teams will be complemented with bots within the limits for ship types and tiers for this particular battle tier. It means each team will have the same number of bots.
  • A visual notification about the maximum waiting time and possibility of matching bots to the battle is on the battle loading screen.

Other restrictions in Co-op Battles

  • The bot team mirrors the player team by type and tier.
  • at most 4 battleships and 4 destroyers helmed by players[6].
  • Bots may be added to the player team[12]:
    • cruiser rule: if cruisers are the most numerous type, a destroyer is added.
    • destroyer rule: if destroyers are the most numerous type, a battleship is added.
    • battleship rule: if battleships are the most numerous type, a cruiser is added.
    • if two or more types are the most numerous, the rules are applied in the following order of priority: battleship rule, cruiser rule and destroyer rule.
    • Any bot-driven ship matched into a battle may only be taken from the list of researchable ships, and its tier must equal the lowest tier brought to battle by a player, provided that the required type of ship is available at that tier.
    • If there are no ships of the required type, the next ship type is selected in this order: battleship, cruiser, destroyer.
    • Sometimes an aircraft carrier is added.
    • Bots are added until there are nine players on each team.

Divisions

Divisions of up to three ships can be created. Currently divisions can only have one carrier. Divisions are restricted to a one tier spread[1]. A division with a Tier VI ship, for example, could include ships of Tier V and Tier VI, or Tier VI and Tier VII. Tier V, VI, and VII ships are not allowed in the same division at the same time.

Previously, there were no restrictions on division tiers, leading to "fail divisions" of high tier ships (such as Tier IX or X) divisioned with low tier ships (Tier I or II).

When placing divisions in a match, Match Maker will only consider the highest tier ship's Match Making tier range for purposes of tier placement. For example, a Tier 5's normal Match Making is +2/-1, so it will normally only see Tier 4 through Tier 7 ships in matches. Similarly, a Tier 6's normal Match Making is also +2/-1, so it will normally only see Tier 5 through Tier 8 ships in matches. When divisioned with ships of the same tier, the division will see the normal Match Making for that tier. For example, a division of only Tier 5s will only see matches with Tier 4 to Tier 7 ships. A division of only Tier 6s will only see matches with ships from Tier 5 to Tier 8.

However, when a division is made up of ships of unequal tier, only the top tier ship's tier range will be considered. Thus, let us say the Tier 5 and Tier 6 above form a division. Match Maker will only consider the Tier 6's tier spread. The Tier 6 can see Tier 8 matches, so the Tier 5 in the division with it will now also be subject to seeing Tier 8 matches where it normally would only be able to see Tier 7s max. This results in an effective +3/-1 Match Making spread for the Tier 5 when divisioned with a Tier 6. This is commonly called a "fail division" because this puts the lower tier ship in a battle tier they normally cannot see.

Ship Performance Factors

For each ship there are seven performance factors that provide a basis for comparison of any one ship against another in game. These performance factors are expressed on a relative scale of 0 (worst) to 100 (best). Each performance factor is based on the ship's abilities. Note that these factors are just a basis for comparison, and can change based on what modules, upgrades, or captain skills the ship is equipped with.

  • Survivability is a measure of the ship's ability to take damage and keep fighting. Its mainly all about hit points. The T10 BB's IJN Yamato, KMS Großer Kurfürst, HMS Conqueror, USS Montana and MN Republique share top Survivability factor in-game with 100. Many tier one ships share the worst, with 4.*
  • Artillery is a measure of the ship's firepower with its main and secondary guns. The main battery firing range in kilometers and the number, type, and positions of the main battery and the secondary armament guns contribute to this factor. The US T10 BB Montana, IJN Yamato and UK T10 BB Conqueror have the top Artillery factor in-game of 94. Asides tier 1 ships, The IJN T2 DD Tachibana has the worst with 2.
  • AA Guns is a measure of the ship's anti-aircraft defences and its ability to defend itself from air attacks. The number and caliber of the on-board AA guns contribute to this factor. The U.S T10 CL Worcester has the best AA Guns factor in-game of 96. Many ships, such as the US premium T4 BB Arkansas Beta, IJN premium T2 DD Tachibana, Russian premium CA Oleg and KM T3 BB Nassau's A hull have the worst - 0 - because they are not armed with any AA Guns.
  • Maneuverability factor is a measure of the ship's ability to maneuver, make turns, and maintain speed while turning. Three other factors affect Maneuverability, the ship's "Maximum Speed" in knots, its "Turning Circle Radius" in meters, and its "Rudder Shift Time" in seconds. The IJN T5 DD Minekaze and Russian T5 DD Podvoisky share the best Maneuverability factor in-game - 95. The US T4 CV Langley has the worst at 7.
  • Concealment factor is a measure of the ship's ability to remain undetected by the enemy. The Concealment factor is a calculated parameter influenced by the ship's "Surface Detectability Range" and an "Air Detectability Range", each are also specified and expressed in kilometers. The IJN T2 DD Tachibana and it's T10 cousin Shimakaze has the best Concealment factor in-game of 98. The US T10 CV Midway has the worst at 5. Many camouflages, such as the Type-1 Camouflage further reduces the detectability range by sea of the ship it is mounted on by 3%.
  • Torpedoes is a measure of the torpedo capability of those ships which carry torpedoes. The number, type, and position of the torpedo tubes and the range of the torpedoes contribute to this factor. The IJN T10 DD Shimakaze has the best Torpedo factor in-game of 60. The IJN T2 DDs Umikaze and Tachibana, as well as the USS Smith have the worst rating which is 4. Those ships not armed with torpedoes have no Torpedo factor.
  • Aircraft is a measure of the aircraft capability of those ships which carry aircraft. The total number of squadrons, number of planes, and the type and capabilities of each of the planes: fighter, dive-bomber, or torpedo-planes; determine the Aircraft factor. The USA T10 CV Midway has the best in-game Aircraft factor of 86. Cruisers (beginning at T5 except the T4 IJN Kuma), and Battleships of certain tiers, carry 1 to 3 fighter/recon aircraft. Battleships can only mount catapult fighters at tier 7 and up, with the exception of Dunkerque. Only CVs have an Aircraft factor.
