Uwe:
The limiting factor that led to segmented boosters was the maximum batch
size for solid propellant production which was around 100 tonnes through
the mid-1990’s.
As I recall—I was last at Kourou 20 years ago—the then plan was move to
continuous processing.

Any idea how ArianeSpace solved this issue on the ArianeV SRBs ?
