@tiag I did a small experiment, because the resupply issue got me thinking, when you said that resupply phase takes place twice per hour.
I started a new Rolling Fire campaign. I didn’t touch any setting, PAK, mission type, just started it and let the clock run.
First, I stopped it at around 05:00z.
On the red side, some squadrons show it’s next resupply at 06:00z, and some still show 03:00z (seems like the ones that had no losses), but NO squadron got any additional airframe.
Then, I left it run past 06:00z.
Again, some squadrons show the next tick as 09:00z, and the ones with no losses still show 03:00z. And still NO new airframes were added to any squadron.
Just a couple of examples:
Interestingly, all Blue side squadrons show as 00:00z, also with no new airframes.
Example:

This seems consistent to the campaign I posted in the OP. It looks like airframe resupply is not taking place at all? As I mentioned, I had the feeling that, in the OP campaign, I did get a few more airframes, but maybe I was wrong, and the fact is that every single squadron shows as Last Resupply = 0, Plus, looking closely, the number of aircrafts left feels too low.
