Aerospace defense contractor Amentum Services Inc. is consolidating its operations and moving its headquarters from Germantown, Maryland, to Chantilly, a move that will add 157 jobs, Gov. Glenn Youngkin announced Monday.

The relocation comes a little more than a year after Amentum completed its $1.9 billion all-cash purchase of Falls Church-based government contractor PAE Inc. The move across the Potomac River includes an investment of $495,000. Virginia competed with Maryland for the project.

“Fairfax County offers the location, access to decision-makers, and talent pipeline that global providers like Amentum are seeking, and we are proud to welcome the company’s leadership and operations team to Virginia,” Youngkin said in a statement. “Amentum joins the ranks of the commonwealth’s diversified ecosystem of more than 800 corporate headquarters across a broad cross-section of industries.”

The new headquarters consolidates operations at Amentum’s office at 4800 Westfields Blvd.

“The relocation of our company headquarters to Chantilly grants more convenient access not only for our local employees, customers and partners, but also for everyone in our extended team who are doing business in the Washington, D.C., area,” Amentum CEO John Heller said in a statement. “We look forward to strengthening our connections with and expanding our business in the Northern Virginia area and establishing our new headquarters as the ideal centralized location for our global organization.”

Amentum has more than 44,000 employees in 85 countries, including locations across Virginia in Alexandria, Arlington County, Chantilly, Dahlgren, Falls Church, Fredericksburg and Norfolk.

The Virginia Economic Development Partnership worked with the Fairfax County Economic Development Authority to secure the project for Virginia.
