In 1933 the Starachowice Works received an official order to build prototypes for a 75 mm anti-aircraft gun. The design was completed in 1933 by the engineer Maj. Szymański from the Institute of Technology and Armaments. Who was assisted by Ing. Waclaw Stetkiewicz and M. Eng. Leszek Kistelski from the Starachowice Works. The first prototypes were completed and sent for testing in 1935. The report from the testing indicated minor deficiencies in the gun carriage, which it believed could be successfully resolved. However, it wasn't until 1937 that those defects were resolved and the wz.36 went into production.[1]
Two variants were proposed, the wz.36 which was mobile anti-aircraft gun mounted on a four-wheeled dual-axle carriage with cruciform outriggers towed by a C4Phalf-track and the wz.37 a statically emplaced anti-aircraft gun. The Polish Army planned to acquire 60 mobile batteries of 3 guns (180) and 70 static batteries of 4 wz.37 guns (280) for the defense of high value targets. However, by the outbreak of war in 1939, only 52 of the 460 ordered had been built.[1]
