Factory 847 is the name used in open reference works for the Chinese development and production line behind the Type 63 107 mm multiple rocket launcher. Those references treat it as a historical industrial designation rather than a public-facing company with a modern standalone site.
The public record is narrow but useful: Factory 847 anchors the Type 63 launcher family, while later producer references point to NORINCO as the public corporate umbrella associated with continued Chinese production and export context. The Type 81 truck-mounted launcher and Type 63-I lightened launcher are best treated as Type 63-family variants unless stronger plant-level documentation separates them.

Factory 847 is a historical Chinese factory designation with sparse standalone public corporate documentation. Open references usually identify the related Type 63 line by the plant number and then map later production references under NORINCO, so this profile keeps the corporate interpretation conservative.
