U.S. Army Developing Advanced Missile Defense Strategy Aimed at 2040

HUNTSVILLE, Ala. — The U.S. Army is preparing to unveil a new missile defense strategy aimed at addressing threats through 2040, according to Lt. Gen. Sean Gainey, commander of the Space and Missile Defense Command.

The updated strategy, slated for release in October 2025, is a collaborative effort involving the Space and Missile Defense Center of Excellence, Army Futures Command, Army Air and Missile Defense Commands, and the Fires Center of Excellence. It will align with the Army’s multidomain operations doctrine and warfighting concepts, Gainey said during a press briefing at the Space and Missile Defense Symposium.

The Army’s previous strategic air and missile defense vision, issued in 2018, focused on the period leading up to 2028. It addressed organizational structure and operational capabilities, but Gainey emphasized that it’s now necessary to plan further ahead.

The forthcoming strategy will incorporate lessons learned from recent conflicts, including those in Ukraine and the Middle East, to shape the missile defense force needed for 2040. Gainey highlighted the importance of adapting to evolving threats and establishing a robust foundation for future capabilities.

Key elements of the new strategy will include maintaining 360-degree coverage, leveraging open architecture, and utilizing advancements in artificial intelligence. The approach will prioritize speed, cost-effectiveness, and adaptability in developing and deploying new capabilities.
