===Sortie Cost===
There is a flat cost associated to LBAS sorties. This is separate from the [[Land-Based_Air_Squadron#Resupply|resupply]] costs detailed above.
'''Land-Based Attack Aircraft'''
<math>\text{Fuel} = \text{Plane Count} \times 1.5</math>
<math>\text{Ammo} = \text{Plane Count} \times 0.7</math>
'''Other Planes'''
<math>\text{Fuel} = \text{Plane Count} \times 1.0</math>
<math>\text{Ammo} = \text{Plane Count} \times 0.6</math>
* <math>\text{Plane Count}</math> is the remaining planes in the slot.
** <math>4</math> for reconnaissance planes.
** <math>18</math> for all other planes.
'''Notes:'''
* This cost is calculated '''per squadron'''.
** Empty slots do not cost anything.
* The resources are deducted when the sortie is started.
* Costs are '''rounded up''' except for the land-based ammo cost which is '''rounded down'''.
===[[PBY-5A Catalina]] rescue function===
[[File:Catalina rescue.png|thumb|right|3 bubbles Catalina rescue]]
{{Equipment/Link|PBY-5A Catalina}} placed in LBAS have the ability to rescue fallen pilots that lose their planes in Land-Based Air Operations.
* The rescue function will not trigger if :
** a too large amount of Catalina is shot down
** no planes are lost
** a 2nd wave does not occur due to all enemies dying.
* The rescue can happen if the 2 LBAS attacks are split on different nodes, the rescue happening on both nodes.
* Rescue only applies to bases with a Catalina equipped.
* There 3 types of rescue that can trigger depending on the setup :
** Type 1, with 1 bubble, saving 1 slot
** Type 2, with 2 bubbles, saving 2 slots
** Type 3, with 3 bubbles, saving 3 slots.
* Aircraft rescued by the Catalina will be restored :
** it saves some bauxite when resupplying,
** it '''does not''' prevent any loss of [[Plane Proficiency]].
* The number of Catalina used to rescue affects the rescue ratio.
** Catalina ranks do not affect the rescue ratio.
*Losses are reduced per rescued slot (the final resupply value is about ~60% of what should be lost in battle). This doesn't carry over bases that are splitted.
</div>
==Air Defense==
<div class="mw-collapsible mw-collapsed">
In [[6-5]] and some event maps, the enemy will raid the bases during the sortie. A base on air defense will attempt to intercept those raids to mitigate the damage done.
* When intercepting enemy bombers, the '''first slot in the base will intercept the first slots on the enemy attackers''' and so on.
** Planes with a higher anti-bomber {{Anti-Bomber}} stat should be deployed in slots with opposing bombers to minimize the damage taken.

Unlike normal aerial combat, the shootdown for base defense is based on the anti-bomber {{Anti-Bomber}} stat of the plane. This is determined on a slot-by-slot basis as opposed to the whole air wing basis of aerial combat.

'''Notes:'''
* Planes with interception {{Interception}} and anti-bomber {{Anti-Bomber}} stats are much more effective.
* Obtaining air superiority reduces the chances to take no damage with planes that have 6 or more {{Anti-Bomber}}.

===Land Base Air-Raid===
During a sortie, an alert will say {{color|red|"Enemy formation approaching! Enemy aircraft are approaching our base" (敵編隊接近中！我が航空基地に敵機接近中。).}}
* The chance that this happens is random but increases when approaching the boss.
** At the boss node, the chance is 100%.
* The damage dealt will not destroy the base.
* Either '''fuel or bauxite''' will be randomly lost for any damage done to the base. It is calculated as follows:
** <math>\text{Resource Loss} = \text{Damage} \times 0.9 + 0.1</math>
*** <math>\text{Damage}</math> is the damage taken by the base.
** The resource loss is rounded down.
** The maximum cost is 179 fuel/bauxite.
* Only 1-4 planes in the '''first slot''' are lost due to damage.
** Reconnaissance planes can '''only lose 1''' plane per raid.
** If a slot only has 1 plane remaining, the loss will be applied to the slot below.

|-
|}
'''Notes:'''
* Because the plane losses are not that high and the resource loss is limited, it is recommended to '''focus all available bases on attack''' instead, unless getting LBAS AS is needed.
===High Altitude Air-Raid===
This is a special air-raid where the LBAS is attacked by "high-altitude bombers". The defense power of the base is severely reduced unless one or more {{EquipmentLink|Me 163B|Prototype Shuusui|Shuusui|text=Land-based rocket interceptors}} are present.
{{Category:High Altitude Interceptors}}
* At least 2 "High Altitude Interceptors" are needed to remove the defense penalty.
* The multiplier is calculated based on the number of rocket interceptors in '''all bases'''.
* Damage works the same way as normal base raids.
===Superfortress Air-Raid Sequence===
A special air-raid performed by Abyssal's '''[[Abyssal Sky Super Fortress|Superfortress]] ([[Abyssal Sky Super Fortress Kai|Kai]])''' on certain maps.
'''Unlike previous mechanics in the game, this mechanic is a "Quick Time Event" (QTE), and requires '''monitoring and timing of releasing the LBASs to successfully intercept the enemy air-raid by pressing a button at the right time.'''
* This means that the player is required to pay attention while the fleet is on the map screen.
* The heavy air raid will occur at random at any given point during sorties on E5 and may even sometimes not happen at all.
[[file:LBAS_new_raid_guide.jpg|thumb|right|The location of the first bomber indicates the timing of when to press the button]]
When the LBAS sequence occurs, the screen will turn darker with 1 to 3 abyssal bomber(s) flying toward the land base point, and a button will appear on screen:
* When this button is pressed during the QTE, the exact moment it is clicked on, directly affects the amount of defending land bases that can participate in air-raid combat.
** No LBAS will be able to appear if this button is not pressed at all, no matter how many land bases are set to '''Air Defense.
** Pressing the button '''before 2.5 seconds or after 3 seconds''' after it appears will result in fewer (1~2) land bases appearing to provide defense.
** Pressing between 2.5 s and 3 s will result in maximal 3 land bases appearing to provide defense, depending on how many defense bases are set.
** While there is no visual indicator given, the best result may be achieved when the first bomber reaches the area marked on the picture to the right.
* Heavy Land Base Air Raid will consist of several waves of abyssal bombers appearing once the sequence starts with:
** 1 wave in Casual and Easy
** 2 waves in Medium
** 3 waves in Hard
** When multiple waves occur (Medium/Hard), plane losses of abyssal bombers will be reset for every wave, but losses of player's LBAS will '''NOT''' be reset.
** Therefore, map unlocks requiring air superiority can be fulfilled with the result of any wave, mostly the 1st wave, that can differ from the result of the final wave which is actually displayed in-game.
* The LBAS group needs to be armed in '''"Air Defense"''' mode with planes that can provide "high altitude interceptions" or are armed with "diagonal upward guns" to be more effective against those bombers. Interception fighter power bonus formula is: <ref>Source: https://twitter.com/yukicacoon/status/1507242405841432576</ref>
<math>\text{Bonus}_\text{Multiplier} = \biggl ( \text{A}_\text{Multiplier} + \text{B}_\text{Multiplier} + \text{C}_\text{Multiplier} \biggl ) \times \text{D}_\text{Multiplier} + \text{D}_\text{Flat}</math>

==Evacuation==
<div class="mw-collapsible mw-collapsed">
Bases set to "evacuate" will not lose planes to damage from "air-raids".
* Resources will still be lost to damage.
* Evacuated planes will recover morale slower.
* Bases that have been evacuated will not cost resources on sortie.
'''Notes:'''
* Can be used to preserve planes in bases not currently used.
* It can also save on sortie costs if a particular base is not currently needed on the sortie.
** E.g. a base with bombers when focusing on air defense.
</div>
==Rest==
<div class="mw-collapsible mw-collapsed">
During rest, the morale of the planes will recover faster.
* The natural regeneration of bauxite {{Bauxite}} is '''severely reduced''' when a base is being rested.
** It is '''halved''' for one base and reduced to '''1/6''' for two bases.
** It can be further reduced by increasing the LBAS group's level (see [[Land-Based Air Squadron#Land_Base_Maintenance_menu|here]]).
* It takes about 24 min to recover from 0 fatigue in rest mode on level 0.
** It's reduced down to 18 min at level 2+.
'''Notes:'''
* Because the only disadvantage of rest applies when being below the resource soft-cap, it can be freely used to recover bases faster when being above the soft-cap.
