This Škoda gun was originally developed for the never-built Ersatz Monarch battleships as anti-torpedo boat guns (TAG) and anti-aircraft guns (BAG). They were first used on the minelayer Chamäleon and the river monitor Temes after she was salvaged and rebuilt. Additional guns were used in shore batteries.
After the war some of these guns were used on Yugoslavian minelayers. Some were relined to use 83.5 mm projectiles in 1931 in order to use the same ammunition as the Škoda M22/M24 gun.
A total of twenty-eight guns were delivered to the Navy and an additional eighteen to the Army.
In 1918 Škoda built a new 9 cm G. L/35 BAG gun. This fired the same projectiles as the L/45 gun at a muzzle velocity of 2,300 fps (700 mps). The shorter barrel was intended to make the gun easier to handle.
