Hypothetical
I would guess the idea of “Hypothetical” builds immediately conjures thoughts of “Luftwaffe ’46” subjects for most of us. Back in the ’90s I think there were whole TV series built on this idea! Although such subjects do have some passing interest to me (really, who doesn’t like seeing outrageous jet fighters that never progressed past napkin doodles?!) I bet most readers will not be too surprised to hear I’m actually more interested in things with more plausibility. Especially aircraft that could have appeared in the middle of the War without such massive disruptions of the space/time continuum…
So for my first foray into this theme I won’t do any Luftwaffe ’46. You may not believe me when you see my list! In order (from least to most, errr, “hypothetical”) I will do an A6M2-N Rufe, F5F Skyrocket, Messerschmitt Me 509 and P-80 Shooting Star. If any of that makes you question my “least to most” claim, let’s just say I consider actual changes to War timelines more significant than production or engineering decisions.
As always, I won’t be giving away any more spoilers about my subjects until their individual posts drop.
I have built a few such models before. I think its occasionally fun to visualize things that never quite were. I also like it as an exercise in looking at how things came to be, and what it would have taken to change them. Hopefully this will be fun for all of us, or at least we can have a good argument about why I think its fun. I think these will all be pretty simple builds and will take about three weeks each.

An interesting perspective, Dave. There were quite a number of designs which were not introduced because it was felt the disruption in production was not worth the improved performance. That may well be the case, maybe not, hard to say with certainty. Some were not adopted because the next design in development was thought to be better.
Yeah there’s a lot of interesting reasons why aircraft did or did not enter service. And obviously three of the four types I’m doing DID get built, some of my “hypotheticals” will be pretty marginal. What, in another genre, would be called “low fantasy”.
