The 9 cm PL kanon vz. 12/20 (Anti-aircraft Gun Model 12/20) was a Czech anti-aircraft gun used during the Second World War. 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. Twelve were in German service between August 1943 and June 1944.
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.
