It also designs, manufactures and refurbishes smoke, riot control, and incendiary munitions, as well as chemical/biological defense operations items.

At the height of World War II, the plant expanded from making magnesium and thermite incendiary munitions to a chemical warfare manufacturing facility as well, producing lethal gases and chemical compounds installed in artillery shells and specifically designed bombs.

[3] In an incident after World War II, several captured German rockets containing mustard agents were accidentally launched into the surrounding countryside.

[4] The Pine Bluff Arsenal chemical weapons stockpile consisted of declared quantities of rockets, land mines, and ton containers.

Operators heated the TCs to 1,000 °F (538 °C) for 60 minutes, well in excess of the standard required by the Army to achieve chemical agent decontamination.

PBTCDF successfully completed operations in July 2011; one result of this process was the recycling of more than 6,500,000 lb (3,200 short tons; 2,900 t) of steel.

The PBEDS inventory included 4.2-inch mortars as well as German Traktor rockets, which were captured during World War II.

PBEDS operators destroyed the last munition in April 2010, marking the destruction of all non-stockpile materiel declared when the United States entered into the Chemical Weapons Convention (CWC).

Completed on Dec. 28, 2006, it marked the end of the PB IBPF demolition and the last former chemical warfare production facility destroyed in the United States.

This accomplishment was significant since it enabled NSCMP to surpass the Chemical Weapons Convention (CWC) treaty milestone of demolition of all the nation's former production facilities four months ahead of schedule.

PBMAS determined the contents and explosive condition of items before processing to enhance safe handling, treatment and disposal.

Prior to PBMAS, NSCMP also assessed 300 drums that contained recovered chemical warfare materiel, known as the XP300 mission.
