Milan Ordnance Depot and Wolf Creek Ordnance Plant were established in 1941. In 1943, they merged, becoming Milan Ordnance Center (MOC) and later Milan Arsenal (MA) in 1945. In the 1960s, it became MLAAP.
Capabilities
Capabilities of the center included: load, assemble and pack ammunition; 40 mm cartridges; mortars and components; artillery projectiles; ignition cartridges; propelling charges; bursters; grenades; Tactical Missile System; demilitarization/disposal; renovation/reclamation; development and production test support; and logistical support.
Facilities
MLAAP was housed on 22,531 acres (35.205 sq mi) (90.48 km2) with 1,450 buildings and 873 igloos and a storage capacity of 2,270,000 square feet (211,000 m2).
BRAC 2005
MLAAP gained the 155 mm artillery and 60 mm, 81 mm, and 120 mm mortar workload from Kansas Army Ammunition Plant. It also gained the 105 mm and 155 mm artillery, Multiple Launch Rocket System and hand grenade, and 60 mm and 80 mm mortar workload from Lone Star Army Ammunition Plant. Both facilities were closed under Base Realignment and Closure 2005.
American Ordnance Involvement
American Ordnance LLC, operating contractor of Milan Army Ammunition Plant, moved Milan's operations pertaining to ordnance manufacture to Iowa Army Ammunition Plant beginning in 2009. Milan Army Ammunition plant, while still an active facility, no longer produced military ordnance.
Closure
In August 2019 Joint Munitions Command completed the movement of ammunition and explosive stocks stored at MLAAP and declared the plant no longer required for mission needs. The Army proposes to close and dispose of the approximately 22, 531 acres.
The date that the plant will be vacated is not known.[1]
Environment
MLAAP was placed on the Environmental Protection Agency's National Priority List (Superfund) in 1987.
