The value of the award -- from the U.S. Army Chemical Materials Agency and the Program Executive Office, Assembled Chemical Weapons Alternatives -- for all awardees is $489 million.
"SAIC is committed to supporting the CMA and PEO ACWA in destroying the nation's stockpiled and non-stockpiled chemical weapons," said JT Grumski, SAIC senior vice president and business unit general manager.
"Ridding our nation of these old and potentially hazardous chemical weapons is vital to our nation's health and security and we're proud to be part of the solution."
Under the award, Science Applications International Corp. will compete for task orders to provide services such as program management and oversight for chemical weapons storage and demilitarization, field office services, engineering and design, monitoring, technical analysis, quality assurance, safety, security, training, and testing services.
The CMA is responsible for the storage of chemical weapons at a number of sites and SAIC has supported its work for more than 20 years.
