DTRA’s justification documents a sole-source bridge contract awarded to keep critical Defense Stockpile Management Systems running while a future requirement is prepared for competition.
- **Notice and award:** The notice is a Justification and Approval for Contract HDTRA126C0035, awarded to General Dynamics Information Technology, Inc. on September 24, 2026.
