North Korean defector "Lee Yŏng Shik" (pseudonym) says this factory produces nozzles that are used in the assembly of missiles at the No. 26 Factory in Kanggye, Chagang Province. There are a number of ways to interpret Lee's statement about "nozzle production." The simplest interpretation is that this facility produces "nozzles" for unguided rockets. In the case of simple rockets, the nozzle is screwed into the back of the rocket airframe. If the No. 26 Factory, as reported, produces relatively basic munitions, this interpretation is plausible.

Alternatively, his statement could be interpreted as a reference to production of combustion chamber/nozzle assemblies for Scud-type ballistic missiles. In this case, the production process is technically more demanding, and would require components such as mandrels, jigs, a flow former, a brazing furnace, a circumferential welding machine, a hyrdrostatic test bench, and a metallurgic X-ray machine. [Note: There appears to be no other open source information about this facility.]
