Precision Electro-Mechanics Plant (ZTEM) is a Belarusian state defense enterprise founded in 2009 to develop and produce military products, with a catalog-relevant role in missile weapons, rocket systems, training equipment, and the Polonez family of long-range rocket and missile systems.
1 weapon systemsZTEM was established as a Belarusian republican unitary enterprise under the state military-industrial authority, initially to carry out work connected to military products and other specialized goods and services.
The plant's public materials describe research, development, production localization, testing, modernization, and disposal work for missile and rocket weapons. Its own catalog identifies V-200/B-200 Polonez and V-300RK Polonez-M as central missile-weapon programs.
For this archive, ZTEM is treated as the missile-system developer and producer connected to the Polonez launcher entry, while the vehicle chassis role remains separately associated with MZKT/Volat where the weapon record names that manufacturer facet.
ZTEM's official about page identifies Polonez as one of the plant's missile-weapon products; Belarusian state-industry reporting describes B-200 Polonez deliveries to Belarusian forces and its 301 mm launcher configuration.
