Kratos Defense & Security Solutions (KTOS) said Tuesday it was awarded a $34.9 million contract modification to provide support services to the Valkyrie unmanned aerial systems for the US Marine Corps.

The new deal expands the scope of a previously-awarded cost-plus-fixed-fee contract, the company said.

The contract modification provides additional non-recurring engineering and material and additional flight tests.

Work under this contract will be performed in Sacramento, California; Oklahoma City, Oklahoma; China Lake, California; and Patuxent River, Maryland.
