We had discussions here about strategic bombing strategy and priorities. Apologies in advance that I forget who offered what advice, but one person was quite vocal about going after supply generation. By far most favored going after advanced airframe production. I chose to go after advanced airframe production.
I got the strategic bombing campaign going a little earlier than historical IIRC. Things got off to a decent start. Then the defenses ramped up much more quickly than the bomber fleet could stand the attrition. I had to switch to night bombing. We had a discussion here about night bombing against Manpower versus against specific targets. I chose to restrict my night bombing to Manpower because I feared night bombing against specific factories, etc. might be over powered. I was never able to hit enough of the specific factories I prioritized. Worse, some cities have 0 or only a few Manpower, stymying progress under that restriction. What really was telling was when I started seeing certain advanced airframes in combat far in advance of when I anticipated that was possible. Walter's R&D was simply amazing and far outstripped anything I was able to do to slow it down. When I was able to switch back to daylight bombing, at least partially, I was going after Light Industry and Heavy Industry. I should have chosen to go after supply generation from the very start of the strategic bombing campaign.
As a side not, you might have noticed that at a certain point in the liberation of China, I went after supply generation there even though for play flavor reasons I had resisted doing so in Allies territories.
Although it wasn't strategic bombing to bear on this post in general, the last few days of ultra massive 4EB strikes on HI airbases, especially on or near Kyushu, got so many 500 pound supply hits that I was starting to hope that might influence events at Kanoya when the ground operation resumed.
