I don't know if you understand this but the Bell X-1 was a supersonic research aircraft in the LATE 1940s,no armament,just lots of avionics and research modules.Oh and bright orange.
It's arsenal of research equipment.

Sure but that doesn't make it any less interesting. Besides, the C-47 doesn't have any weapons but people made flight models and cockpits for it.
