DoD policy is to consider international cooperative development only after U.S.-only solutions have been shown to be impractical.?

The Department of Defense (DoD) policy prioritizes U.S.-only solutions for defense development to ensure national security and maintain technological superiority. International cooperative development is considered only when it is demonstrated that domestic options are impractical or insufficient. This approach aims to optimize resources while fostering international partnerships when advantageous. Ultimately, it balances national interests with potential collaborative benefits.
