Fonsini, you remind of a discussion I had with a contractor back in the 1970s who was looking to interest the RAF in wartime disposal drop tanks for the Jaguar force. He had a design based on those of
WWII which he reckoned he could produce at short notice for about £200 a piece. The RAF wasn't interested as they wouldn't believe the price and thought anything aircraft qualified would have to be at £6K each - at which point it wasn't economic in peacetime against much more expensive reusable drop tanks.
What is the price point in peacetime where you could persuade an accountant to start buying FMRs which have have to be thrown every every trip against buying a reusable platform you can bring home but which costs 200+ times as much?
It's the same as the story that the engines for a Mig-21 had a life of about 100 hours because the expected service life of a Mig-21 in war was about 90 hours - why spend money on better materials building an engine which would get shot down anyway? Better to spend the money building cheap engines and airplanes continuously in peacetime so you had the in place capacity to do the same in wartime. But no peacetime accountant will pay for such extravagance.
Maybe computerised lean production with rapidly rerolled production lines, coupled with 3D printing of both plastics and metals, have changed the equation.
