Speed {{Speed}} represents the speed of a ship girl. Ship girls are either '''slow (低速)''' or '''fast (高速)''' by default. As of the [[Game_Updates/2017/January_10|10 Jan 2017 Update]], ship girl speed can be further increased to '''fast+ (高速+)''' or '''fastest (最速)''' by using a combination of {{Turbine}} [[Engine Improvement]]s: a {{EquipmentLink|Improved Kanhon Type Turbine|text=Turbine}} with one or more {{EquipmentLink|Enhanced Kanhon Type Boiler|New Model High Temperature High Pressure Boiler|text=Boilers}}.

There are several effects of increasing ship girl speed:

There are several effects of increasing ship speed:

 

* Meeting routing requirements.

* Meeting routing requirements.

** Slow ships can be sped up to fulfil certain branching requirements.

** Fleet speed affect certain [[Combat/Map Mechanics and Nodes#Routing|map routing]].

*** Note that this does not apply to ''ship type'' requirements. Eg a BB will not count as a FBB where FBBs are specifically required.

*** Note that this does not apply to ''ship type'' requirements (eg. a BB will not count as an FBB where FBBs are specifically required).

** Fast+ and fastest are required to fulfil routing requirements in some maps. Eg. [[World 3#3-2|3-2]] and [[World 4#4-5|4-5]].

*** Most map routings are only effect by slow/fast fleets, '''fast+''' and '''fastest''' being required for routing in very few maps (eg. [[3-2]] and [[4-5]]).

* [[Combined Fleet]] composition.

* [[Combined Fleet#Combined Fleet Types|Combined Fleet composition]]:

** Slow battleships that are fast+ can be placed in the escort fleet.

** BB/BBV that are '''fast+''' can be placed in the escort fleet of STF/TCF (only '''fast''' for [[Warspite Kai]]).

* Evasion increase.

* ''Evasion increase''.

** Although this has been stated by the developers to occur, testing has not shown any significant increase in evasion.

** Although this has been stated by the developers to occur, testing has not shown any significant increase in evasion.

* Because [[Coastal Defense Ships]] cannot equip {{Engine}} [[Engine Improvement]]s, they are the only ship type that '''cannot be sped up'''.

* Because [[Coastal Defense Ships]] (DE) cannot equip {{Engine}} [[Engine Improvement]]s, they are the only ship type that '''cannot be sped up'''.

It is '''highly recommended''' that you have a [[Reinforcement Expansion]] on ship girls that you wish to speed up. It can '''severely degrade''' their combat efficiency if you attempt to speed up ship girls without one.

It is '''highly recommended''' to have a [[Reinforcement Expansion]] on ships that are sped up. Ships sped up without using a RE will have '''severely degraded combat efficiency'''.

 

So far, only 2 types of "boiler" exist in the game, and they are referred to as:

* {{Equipment/Link|Enhanced Kanhon Type Boiler}} = +10 Boiler

* {{Equipment/Link|Enhanced Kanhon Type Boiler}} = +10 Boiler

* {{Equipment/Link|New Model High Temperature High Pressure Boiler}} = +13 Boiler

* {{Equipment/Link|New Model High Temperature High Pressure Boiler}} = +13 Boiler
