In 2019, the Department of Defense published a Missile Defense Review (MDR). Which statement describes a recommendation by the MDR that was implemented?

• A. Develop a space-based component to the missile defense system.
• B. Shut down missile defense operations at Ft Greely, AK.
• C. None of these recommendations were ever implemented.
• D. Build an East Coast site to defend against missiles from Iran.

Answer: (C)

The key idea is about what actually happened after the Missile Defense Review proposed various changes. The MDR laid out several potential directions for modernizing and shaping the missile defense system, including a space-based component and new domestic defense sites. However, none of those specific proposals were put into operation. There has been no deployment of a space-based missile defense layer, no East Coast site built to defend against Iranian missiles, and Fort Greely’s existing homeland defense role has not been shut down. Instead, the department has continued relying on and upgrading current systems (like Aegis BMD and GMD at Fort Greely) without fully implementing those particular recommendations. So the statement that none of these recommendations were ever implemented is the best answer.
