As part of a CIA report on Yugoslavia, an annex onYugoslav military capabilities notes that “the Yugoslavs themselves produce . . . chemical warfare material. . .” This statement is not elaborated upon but probably relates to the well-established indigenous production of defensive equipment.

1976 to 1988
The Jastrebac project is undertaken. This project involves detailed research into weaponization, testing munition designs, production and munition filling equipment, dynamic tests to assess munition performance under field conditions and ultimately including open-air testing of CW filled munitions. Small scale production of Sarin and Mustard agent is associated with this program.

Limited production of sulfur Mustard and Sarin is undertaken at the Potoci facility. Although there is an annual production capability of forty tons of Sarin and 30 tons of Mustard no more than 4.5 metric tons of Sarin is produced over the entire period.

At the Miloje Zakic complex, Yugoslavia commences production of a new modern gas mask design under the designation M-2. The mask is a Yugoslavian redesign of the earlier M-1 model.

There appears to be some production for export and production by Egypt is licensed at some point in the 1990s.
