STV GROUP a.s.

STV GROUP a.s. is a Czech defense manufacturer focused on large-caliber ammunition, mortar and artillery rounds, explosives, ballistic protection, and repair or modernization work for heavy military equipment. The company presents its industrial lineage through the Policka ammunition-production tradition that began in 1920 and identifies itself as the Czech Republic's only large-caliber ammunition manufacturer.

STV GROUP a.s. sits inside the STV INVEST holding and is one of the main Czech industrial names attached to Soviet-standard and NATO-standard ammunition supply. Its official portfolio spans artillery, tank, mortar, medium-caliber, rocket-propelled, and engineer ammunition; the company also lists plastic explosives, explosive reactive armor, loitering-munition products, demilitarization services, military-vehicle repair, and individual ballistic protection.

The Policka connection is important to the manufacturer's public identity. STV GROUP says the First Military Ammunition Factory was established there in 1920, initially producing hand grenades and artillery ammunition for Czechoslovak defense needs. The company says the 2015 consolidation with Policske strojirny created the largest ammunition manufacturer in the Czech Republic and returned that site to active ammunition-related production.

Recent public materials describe growth rather than a static legacy plant. Eurofound recorded a 2025 business-expansion plan at Policka tied to large-caliber ammunition and military-equipment repair, while STV GROUP announced a CZK 5 billion plan to build a more complete Czech production vertical for artillery ammunition components and final loading.

Forecast International lists smoke among the 120 mm ammunition types fired by the 2A60 Nona rifled ordnance on the 2S23 Nona-SVK, while Army Recognition describes the tracked 2S9 Nona as firing smoke rounds in its indirect-fire role. Modern 120 mm smoke products from STV GROUP, Nammo, and Hirtenberger show the class spanning visible and infrared screening, red-phosphorus payloads, white-phosphorus smoke, and other smoke fills depending on the round.
