The Moscow automobile plant began as AMO in 1916, took the ZiS name after its 1928-1931 reconstruction, and was renamed ZiL in 1956 after Ivan Likhachev. Its wartime and postwar output included trucks, ambulances, buses, luxury cars, and military chassis; the plant's official history also records wartime production of PPSh submachine guns, mortars, shells, mines, and rocket-projectile parts.
The same abbreviation also appears in artillery sources because Factory No. 92 in Gorky was named for Stalin during the wartime ZiS gun program. That second context is important for cataloged artillery such as the ZiS-2 57 mm anti-tank gun, whose museum and reference sources explicitly derive the factory designation from the plant name rather than from the Moscow truck works.
For readers comparing older source material, ZiS should be read as a historical Soviet plant designation rather than as a single surviving company. The abbreviation connects state-owned industrial facilities that later continued under other names, most visibly ZiL for the Moscow vehicle plant and the Factory No. 92/Gorky machine-building lineage for artillery.

The ZiS abbreviation appears in public sources for more than one Soviet state plant. This page separates the Moscow vehicle-plant context from the Gorky Artillery Factory No. 92 context when describing systems and sources.
