When the flagship of the 1st fleet is equipped with a {{CommandFacility}}{{Equipment/Link|Fleet Command Facility}} (FCF), it is possible to evacuate {{color|red|'''Heavily Damaged (大破)'''}} mid-sortie. This can help increase the pass rate. The option to evacuate "退避" or not evacuate "退避せず" will appear after the results screen but before the continue/abandon sortie option. The damaged ship to be evacuated and the ship escorting her back will be shown. '''It is not possible to pick which damaged ship gets evacuated and who escorts her.''' The selection is based off '''fleet order''' and the ships higher in the fleet order are selected.

−
* FCF equipped on the 1st fleet flagship.
−
* At least one heavily damaged ship.
−
** The damaged ship must not be the flagship of either fleet.
−
* At least one destroyer '''in the 2nd fleet''' that is not {{color|#f2eb14|'''Lightly Damaged (小破)'''}} or worse.
−
** The destroyer must not be the 2nd fleet flagship.

'''Important Notes'''
−
* It is important to remember that '''only one''' ship can be evacuated per battle. Having more than one heavily damaged ship, imply a retreat.
−
* Evacuated ships and their escorts will '''lose 40 morale and all their remaining fuel'''.
−
* Missing ships will not count towards ships lost for determining victory conditions.
−
* It is possible to fail LoS checks or routing requirements if too many key ships are evacuated.
