PRETIS traces its industrial history to a state factory founded before the Second World War and reestablished in 1948 after wartime destruction. Its official history states that the 1948-1992 product program covered artillery ammunition, mortar ammunition, tank ammunition, rockets, and air bombs, with large-caliber artillery-ammunition production reaching about 1,000,000 units per year when the plant employed about 5,000 people.
After the 1992-1995 war again destroyed the factory, PRETIS rebuilt production lines and imported new production equipment. The company describes continued investment during 2010-2016 to raise production capacity, and lists a current capacity band of roughly 300,000-500,000 pieces per year depending on product type.

Public sources use both 1936 and 1948 as PRETIS founding references. The company history treats 1936 as the original state-factory founding and 1948 as post-Second World War reestablishment; UnisGroup summarizes the factory as founded in 1948.
