Navarro Research and Engineering won a $427.6 million cost-plus-award-fee contract from DOE, leveraging its small disadvantaged business status to create a competitive moat in environmental remediation services.

Gulfstream Aerospace (General Dynamics) secured a $251.1 million sole-source contract for G550 aircraft, strengthening its government aviation backlog with a 9-year performance period through 2028.

The $251M Gulfstream contract was awarded non-competitively, which may invite protests and limit competitive visibility for General Dynamics.
