Pakistan has built a missile factory with Chinese assistance, variously described as being 40 km west or 50 south-west of Islamabad. The populated place associated with this complex, which according to at least one source is located in the Tarwanah suburb of Rawalpindi, presents unusual diversity in transliteration, variously spelled as Fatehjang [the spelling used by the US Government], Fatehjung, Fatehgarh, Fatehgunj and Fatehganj. In August 1996 Asian Age the production facility had been built using pre-fabricated sheds, and was situated in the Kala Chata mountain range. The NIMA GeoNet NameServer is not aware of a "Kala Chata" mountain range, but it is aware of the Kala-Chitta Mountains [Kala Chitta Dhar]. While the center of the Kala-Chitta mountains lie no small distance from Fatehjang, it is evident from satellite imagery that the mountain range extends to the vicinity of this populated place.

As of late 1999 this facility, variously called the National Defense Complex, or the National Development Complex or National Development Centre, was under the leadership of the Director General of the NDC, Dr. Samar Mubarik Mand.

The Prime Minister laid the foundation of the National Defense Complex (NDC) during 1993, and the Shaheen missile program was initiated in 1995 and assigned to the NDC. The Shaheen project used the resources that were available within the various other institutions in Pakistan, supplemented with infrastructure created at the National Development Complex for capabilities which were not available elsewhere in Pakistan. The facilities of SUPARCO were utilized in the Shaheen project, along with the facilities of industry in Lahore, Karachi, Islamabad, Gujranwala, Sialkot, Gujrat and other cities. Missile components from these various facilities were brought to the NDC for final integration.

The NDC reportedly is staffed by specialists from all of the related missile and nuclear developmental organizations in Pakistan, supplemented by about a dozen Chinese technicians who work on missile guidance and control and solid-fuel production. It is reported that the China Precision Machinery Import-Export Corporation (CPMIEC) provided Pakistan with M-11 missile gyroscopes, accelerometers, on-board computers, and other related equipment.
