155mm Projectiles

CAMPAIGN INITIATED: SEPT. 7, 2016
CAMPAIGN COMPLETED: SEPT. 5, 2020

The 155mm projectile was a World War II-type munition. Both the M104 and M110 projectiles contained approximately 12 lbs. of blister (mustard) agent. Colored bands, signifying the chemical agent contained in the munition, marked the outside of the projectile casings. The shell contained an adapter and burster casing that screwed into the nose of the shell, also allowing a fuze to be screwed into the nose of the projectile.

MAIN PLANT

START DATE: SEPT. 7, 2016
END DATE: JUNE 16, 2023
PCAPP mustard agent neutralization followed by biotreatment

Neutralization Followed by Biotreatment

The Assembled Chemical Weapons Alternatives program, the U.S. Army Pueblo Chemical Depot and the community worked together to select neutralization followed by biotreatment to destroy the chemical weapons stored at the depot.

EXPLOSIVE DESTRUCTION TECHNOLOGY

START DATE: MARCH 18, 2015
END DATE: DEC. 5, 2018
Explosive Destruction System

Explosive Destruction System

The Explosive Destruction System, or EDS, augmented the pilot plant to destroy a number of problematic munitions that could not be easily destroyed by the main plant’s automated equipment. During two campaigns from March 2015 to December 2018, the EDS eliminated 951 items resulting in 3.82 tons of mustard agent destroyed.

STATIC DETONATION CHAMBER

START DATE: FEB. 19, 2022
END DATE: JUNE 22, 2023
PCAPP Static Detonation Chamber

Static Detonation Chamber

Static Detonation Chamber supported the chemical weapons destruction progress at the Pueblo Chemical Agent-Destruction Pilot Plant. Three SDC units augmented the main plant by eliminating some 4.2-inch mortar rounds and overpacked problematic munitions.
