The Type 63 family emerged from late-1950s Chinese work on lightweight field rocket artillery. Sources separate the program into launcher and ammunition work: Factory 847 is tied to the 107 mm launcher, while Yang Yintong, Factory 803, and other units are tied to the rockets for that launcher. The resulting system was finalized in 1963 and became a widely exported and copied 107 mm rocket-artillery family.
Public data on individual Chinese numbered factories is sparse, so the scope is narrow: this attribution covers sources that identify Factory 803 or related Chinese state units for Type 63-family rockets. Later export literature and reference sources often discuss the Type 63/81 family under NORINCO or Chinese-origin ordnance, but those references do not turn the historical Factory 803 attribution into a standalone corporate lineage.

Factory 803 is a historical numbered state-factory attribution in public Type 63 program accounts. No dedicated official public website for Factory 803 was found; NORINCO is the current public-facing Chinese state ordnance export site, while the sourced claims rely on Type 63 program references.
