The US Department of Defense has awarded a $118m contract to Leidos to help remove chemical weapons stockpiles at two demilitarisation facilities.

The contract will see the company deliver administrative and technical services support required for the systemisation, operation, and closure of the Pueblo Chemical Depot in Colorado and Blue Grass Army Depot in Kentucky.

These demilitarisation facilities report to the US Army Chemical Materials Activity (CMA) and are the two remaining army installations in the US that store chemical weapons.

The Program Executive Office for Assembled Chemical Weapons Alternatives (PEO ACWA) is responsible for the safe and environmentally sound destruction of the chemical weapons stockpiles.

“We’re honoured to continue being part of the solution to rid our nation of hazardous chemical weapons while ensuring the safety of the public.”

Leidos logistics and mission support senior vice-president Tom Dove said: “Leidos has an extensive history supporting US Army programmes, and over the years we have made long-term investments in our people, capabilities, and execution to support this critical elimination mission through completion.

“We’re honoured to continue being part of the solution to rid our nation of hazardous chemical weapons while ensuring the safety of the public.”

The single award is a cost-plus-fixed-fee contract with a base performance period of one year and includes nine option years.

Work under the contract will be carried out by the Leidos team in Alabama, Colorado, Maryland, and Kentucky in the US.

For the past 25 years, the company has been delivering services in support of this mission, which successfully eliminates chemical weapons at a number of sites across the country while safeguarding the public, workers, and environment.
