You can install a helicopter on multiple available ships by clicking on the "Install" button:

When controlling a helicopter, you need to be careful about the objects and boundaries of the maps (islands, buildings, etc.) - if you collide with them in flight, you can lose the helicopter.
If a ship is destroyed in combat, the helicopter is destroyed automatically with it - it is important to monitor the safety of their units.
For some ships helicopter installation is not available, but all ships have new air defense equipment that allows you to protect from air attacks.
