A rocket silo recipe that outputs more than 1 rocket part per recipe only gets counted as one rocket part for rocket progress, as if recipe completion is what really matters as opposed to the output item count.

A mod and a save on the attachments demonstrate the issue.

Hello, that's indeed how it works - one finished crafting cycle translates to one rocket part. I don't consider current behavior a bug. Because making it work differently requires deeper changes into how rocket silo works and is defined in lua prototypes, I suggest you make a modding interface request, if you wish it to work differently.
