The 9 cm PL kanon vz. 12/20 (Anti-aircraft Gun Model 12/20) was a Czech anti-aircraft gun used during World War II. Those weapons captured after the German occupation of Czechoslovakia in March 1939 were taken into Wehrmacht service as the 9 cm Flak M 12(t). Some guns were reportedly captured in Yugoslavia and the Soviet Union as well. Twenty were in Czech service during the Munich Crisis in September 1938.[1] Twelve were in German service between August 1943 and June 1944.[2]


The PL kanon vz. 12/20 was a modernized version of a pre-World War I anti-aircraft gun. It was mounted on a fixed pedestal.
