  The 85 mm vz. 52 was a dual-purpose field gun and anti-tank gun designed and produced for the Czechoslovak Army during the 1950s.
  
  ## History
  
  When Czechoslovakia was created with the dissolution of the Austro-Hungarian Empire after World War I it inherited a large and capable arms manufacturing industry. This allowed the new state to both design and produce its own weapons for domestic use and for export. After World War II this design and manufacturing experience allowed Czechoslovakia to not only produce Soviet designs under license but to produce equipment for its own use and for export to its Warsaw Pact allies. A consequence of its membership in the Warsaw Pact was that the military hardware it produced used Soviet-caliber ammunition. This standardization was also pursued by NATO members, but with their own calibers of ammunition.
  
  ## Design
  
  Design and development of the vz. 52 began in 1948 at the Škoda Works in Pilsen under the company designation of A22. The vz.52 was designed to fill the same roles as the Soviet 85 mm divisional gun D-44 and used the same ammunition. Its performance was similar to that of the D44 but since it was a unique design it had different dimensions.
