Meet the New Army Small Arms Ammo Facility
In WWII, the Army had 12 War Department-owned and operated plants dedicated to making small arms ammunition, around the clock.
These plants slowly shuttered post-war, with brief respites caused by Korea and Vietnam, until the Twin Cities Army Ammunition Plant, which had been placed on “standby” in 1976, was finally closed in 2005, leaving only Lake City AAP in Independence, Missouri as the only remaining Army small arms plant.
Even at that, Lake City was run on contract at first by Olin-Winchester, then Northrop Grumman, and, since 2019, by Olin-Winchester once again.
Well, the Army is moving ahead with the construction of its first new small arms ammunition factory in decades, and it will be dedicated to making ammo for the Next Generation Squad Weapons.
The new 450,000 sq. ft., facility, built on the Lake City AAP campus, had its groundbreaking on Feb. 5.
It will feature modern manufacturing systems capable of producing “all components” of 6.8×51 Common Cartridge ammunition as part of the NGSW program.

The Army specified this includes “cartridge case and projectile manufacturing, energetic operations for loading and charging ammunition, product packaging, process quality controls, testing laboratories, maintenance operations, and administrative areas.”
Opening by 2028 (ish), it is expected to be able to make upwards of 400 million rounds a year– against Lake City’s legacy capacity to make 1.4 billion rounds of all other calibers. Until then, 6.8 is sole-sourced through SIG.
