Musk to Co-Lead 120-Day Pentagon Study on Cislunar Future Warfare

For space and defense operators, the most consequential phrase in Secretary Pete Hegseth's announcement is "from under the Earth to beyond the moon." Project Meridian explicitly places the Earth-Moon region inside the Pentagon's future warfighting map, elevating cislunar domain awareness, lunar logistics, and space-based sensing from speculative concepts to near-term capability requirements. With SpaceX's Elon Musk as co-director, the study will likely shape how the Space Force and defense suppliers prioritize orbital and cislunar architectures.

On October 1, 2026, Secretary Pete Hegseth used his State of the Force address at Marine Corps Base Quantico to unveil Project Meridian, a high-profile external study of the future of warfare co-directed by Elon Musk, Palmer Luckey, and former House Speaker Newt Gingrich. The panel operates under Emil Michael, the Department of War's chief technology officer, and carries a strict 120-day mandate to "ruthlessly map the trajectory of wars, domains and technologies." The final report will be unclassified and public, with a separate classified annex for military leadership. According to IANS and Fox News via Deccan Chronicle, the co-directors met with Hegseth in a secure facility immediately after the speech, underscoring the initiative's urgency.

With SpaceX's Elon Musk as co-director, the study will likely shape how the Space Force and defense suppliers prioritize orbital and cislunar architectures.

The core rationale, as stated by Hegseth, is that "the best forecasters of future conflict do not solely reside inside the Pentagon. There are obvious biases and risks to asking ourselves to both ask the questions and answer them." This is both an acknowledgement of institutional blind spots and an implicit rebuke of traditional Pentagon planning. The selection of Musk and Luckey is strategic: Musk brings SpaceX and Tesla's launch, satellite, and commercial technology perspective; Luckey brings the defense-tech startup playbook; Gingrich adds political and historical weight. The project is not intended to devise strategy or policy but to identify "the domains that we must conquer and capabilities we must master," then steer a process of "discovering, developing, and fielding" advanced systems for future troops.

The announced scope is unusually expansive, extending "from subterranean depths to the cislunar frontier" and "from under the Earth to beyond the moon." That formulation places underground warfare—a domain rarely addressed in public Pentagon doctrine—on equal footing with the Earth-Moon region. It also draws a direct line to space-based sensing, cislunar domain awareness, lunar logistics, and autonomous underground reconnaissance. Alongside Project Meridian, Hegseth announced six reform initiatives, including a new Autonomous Warfare Command as a four-star functional command, officer training, domestic supply chains, military installations, and religious support. The official release framed the effort with a stark warning: "Should deterrence fail, our warfighters must enter any future conflict with the technological advantage secured through today's foresight, resolve, and preparation."
