Building Aircraft

Can I build aircraft at the other bases? When I go into the Manufacture tab, it appears to only build at my first base. Any help will be appreciated.
Thanks

Presuming you have a powered up hanger at the other bases when construction finishes a popup will appear with a base list asking where you want the aircraft deployed. Same with vehicles.

Yeah, the powered up bit is the important part. When you repair a newly found base, the game will often fail to power up the base’s rooms
