Lake City Army Ammunition Plant

Lake City Army Ammunition Plant (LCAAP) is a 3,935-acre (15.92 km2) U.S. government-owned, contractor-operated facility in northeastern Independence, Missouri.

Lake City was established by Remington Arms in 1941 to manufacture and test small caliber ammunition for the U.S. Army.

Starting in October 2020, Winchester Ammunition was selected by the US Army to operate and manage the Lake City Plant.

[9] Since the late 2000s, the plant has been required to maintain the capability to manufacture 1.6 billion rifle rounds per year.

[5] Historically, LCAAP waste treatment and disposal occurred on-site and relied on unlined lagoons, landfills, and burn pits.
