By 1951, Prime Minister Liaquat Ali Khan had established the Pakistan Ordnance Factory (POF) in Wah Military District, with a civilian chemist, Dr. Abdul Hafeez, serving as director and senior scientist. The POF was oriented towards the production of small arms, ammunition, and chemical explosives. During the period of reliance on United States supply, from 1955 to 1964, there was little attention given to domestic production. Almost all military weapons and equipment were provided by the United States, as part of Pakistan's membership in South East Asian Treaty Organization (SEATO) and Central Treaty Organization (CENTO). By 1963, the Defence Science and Technology Organization (DESTO) was formed by POF Director Hafeez for the purposes of military research and development. After U.S. military assistance was cut off in the Indo-Pakistani War of 1965 (followed by the disastrous 1971 War), Pakistan turned to China for help in expanding its military industrial and production capabilities, including the modernisation of the facilities at Wah.
