From: Planning the end of the world, well out to 2023!
The right hand column of the upgrade options screen is of no value to you in this instance.
1. You must select, by clicking on the yellow Albacore I, on the left column
2. Ensuring "Upgrade Allowed" at the bottom remains toggled on.
3. Then click on "Done".
This will take you back to the air unit screen which should then show the Albacore as the next upgrade model. You then ought to be able to click on "Upgrade Now" which is underneath the withdraw button.
However, if you are really playing with PDU OFF, you should not be allowed to take step 1 above. As I said, the second column is meaningless for you.
Thats what I thought, and with PDU off when you click on the yellow Albacore I it advised the choice is not available (not sure of the wording)
In a more modern engine I suppose it would tempt you by allowing any options unless in the upgrade chain, maybe AE2.
Playing PDU off really hampers the AFB, and I assume the JFB as well. I have 3 Swordfish Sqns with about 6 aircraft between them, and 40+ Albacore sitting in their boxes waiting to be used. The RN has some CV but nothing to fly off them!
