===New Mechanics===
[[File:Airstrike Supported Combat Node.png|thumb|Airstrike Supported Battle]]
*[[LBAS]] can now equip {{Autogyro}} [[Rotorcraft]] and {{ASWPlane}} [[Liaison Aircraft]] (''since [[Game Updates/2023/February 14th|last update]]'').
* There is a new [[node]] type: '''"Airstrike Supported Battle"''' nodes. On this node, the enemy fleet will consist of:
**"Surface enemies" (4-5 SS so far), that are fought like in "Normal Battle" nodes,
**Followed by "air support enemies" (1-2 CVL so far), bringing air support like in "Normal Combat" nodes, and that cannot be attacked, being visually behind the rest of the enemy fleet and with no visible HP.
**It is advisable to use the  {{ToolTip|[[Combat#Formation_Selection|Diamond]]|[[File:Diamond.png]]}} formation in this situation.

==[[Friendly Fleet]]s==
Friendly Fleets (FF) come with a function that allows players to choose if they want to use a FF to aid them in battle or not. It is possible to choose between using "normal only" or "normal and powerful" FF. Powerful FF have an additional cost of '''6 Instant Constructions''' {{IC}} for each time they are deployed in a battle (the blowtorches won't be consumed unless a powerful FF appears).
