I’ve heard some aviation experts arguing that behind civilian side lagging lays the replacement of aviation engineering philosophy with business management mentality whereas, as you pointed out, the military domain was still run by MD team which upholds engineering side.
Come to think of it, makes sense too. I mean, you don’t need really take market demands, finance, costs and what not into account. You don’t need to cut corners. You only have to be precise and meticulous to meet USAF requirements and costs are not a big deal.
Yah its long story. In the end "guns vs butter" getting lumped together as "guns AND butter" in one entity has its effects from the issue baked into "vs" to begin with.
For military ("guns" side), it has long been (in some ways since the Bronze age, but definitely in modern era even more so) premium IP frontloaded, gestated and driven to generally low production numbers and selective top-down supply-fed availability to what we call our men-at-arms.
Things (in modern era) that would just collapse under own weight if you rely on "butter" dynamics market demand, ROI and so on to pull it w.r.t the whole population (and its great differences to the men-at-arms small subset of it)....as these rely on slowly + optimally converting that premium IP to something that addresses more mundane (but obviously still important) large efficient production volumes which operates on lower margins over time (as investment + capital on this basically saturates over time) and is fundamentally oriented to civic needs and subjective preferences that govern free market.
There was an excellent paper I read 20+ years ago, that involved analysing a study that Pentagon commissioned to look into what exactly could be implemented (given top down insular "guns" side its responsible for).... from the command-economy model that USSR had at the time. But the pentagon study always basically realised the distinction and need for insularity to military domain alone.
It in many ways is same reason there is ideological training and high discipline in order to make sense of training in military (and the insularity and requirements to join and progress and so on)....compared to civilian domain where these are far less regimented.
The problem of course for USSR was it extended this kind of thing to the whole gamut of economy (GOSPLAN etc) and it basically came with great costs to what is better handled by "butter" dynamics in consumer goods etc (these do ultimately serve larger population morale, their material needs, overall supply competition to help economize supply side and so on).
i.e It is the butter side that ultimately pays for guns in the end....so there needs to be balance in the approach given relative sizes of each population and agenda.
