Thank you for your help guys
I have my answer now: because the PDU is set to "off" I cannot upgrade the planes. I'm stuck with the Swordfish forever
I am not sure that is true. Your attachment screenshot shows the upgrade as SwordfishI is selected. Have you tried selecting Albacore? If you have the squadron is set to "Upgrade allowed" and it allows you to change to Albacore, that is a valid upgrade path with the PDU OFF setting and you should be able to set that upgrade. As was mentioned, it may cost PP. If the game does not let you change the upgrade to Albacore, you are indeed stuck with Swordfish.
Once the upgrade to Albacore is accepted by the computer, getting the upgrade to happen is a matter of supply and time. If the carrier is at a large enough base with good supply, there can still be a time lag of days for the aircraft to arrive. During this time "Upgrade now" will be greyed out but at some point the upgrade will happen automatically, or the "Upgrade now" text will turn yellow, indicating the aircraft have made their way from the pools to the base. You can then select "Upgrade now" and get your Albacores.
I had this issue at Colombo and other large bases with lots of supply, and a Command HQ present. The time lag for transferring aircraft from the pools seems to be the only explanation for why it does not happen right away.
