"Palmer Luckey, the founder of Anduril Industries, has sparked debate by suggesting that the future of warfare may not be in space, but beneath the Earth’s surface. His vision of subterranean defense challenges conventional thinking and opens up a provocative conversation about how nations might prepare for conflicts in the 21st century."
Palmer Luckey’s Bold Claim
Most tech billionaires today are obsessed with space. Elon Musk dreams of colonizing Mars, Jeff Bezos imagines orbital habitats, and Sam Altman has shown interest in rocket ventures. Against this backdrop, Palmer Luckey’s statement feels almost radical. During a recent interview, he argued that “the subterranean domain will be the defining space for national defense.”
Luckey believes that while space is vast and alluring, the Earth’s crust offers a more immediate and practical frontier. His reasoning is simple: there is far more underground terrain than usable surface land or airspace. If military technology could harness this hidden domain, it could change the way wars are fought.
Why Underground?
The idea of underground warfare isn’t entirely new. History is full of examples: tunnels in Vietnam, bunkers during World War II, and underground missile silos during the Cold War. But Luckey envisions something far more advanced—vehicles and systems designed to move stealthily beneath the Earth, much like submarines glide through oceans.
Key Advantages
Stealth and protection: Underground systems would be shielded from satellites, drones, and aerial surveillance.
Strategic mobility: Armies could move equipment and personnel unseen, bypassing traditional defenses.
Resilience: Subterranean bases could withstand missile strikes and aerial bombardments better than surface facilities.
In Luckey’s view, these advantages could make underground warfare as transformative as the introduction of submarines in naval combat.
The Technology Challenge
Of course, digging through the Earth’s crust is no small feat. Unlike water, soil and rock present immense engineering challenges. Creating vehicles that can tunnel quickly, quietly, and safely would require breakthroughs in robotics, materials science, and energy systems. Anduril Industries, Luckey’s defense startup, has already built autonomous drones and surveillance towers, so his company has a track record of turning ambitious ideas into reality.
But critics argue that subterranean warfare may be impractical. The cost of building underground infrastructure could be astronomical. Maintenance and logistics would be complex. And there’s the question of whether such systems could ever match the speed and flexibility of aerial or space-based platforms.
Reactions and Debate
Luckey himself admits that people often think he sounds “crazy” when he talks about this vision. Many defense experts remain skeptical, preferring to focus on space, cyber, and artificial intelligence as the future domains of conflict. Yet his comments have stirred curiosity. Social media discussions highlight both fascination and disbelief, with some calling it visionary and others dismissing it as science fiction.
Still, history reminds us that radical ideas often shape the future. Submarines, airplanes, and drones were once dismissed as impractical. Today, they define modern warfare. Could underground vehicles be next?
Strategic Implications
If Luckey’s vision were realized, it could reshape geopolitics. Nations with advanced tunneling and subterranean systems would gain a new form of strategic advantage. Imagine underground highways for military convoys, hidden missile launch sites, or subterranean drone hubs. Such capabilities could make traditional surveillance and deterrence strategies obsolete.
Moreover, underground warfare could complicate arms control. Treaties that regulate nuclear weapons or space militarization might not account for subterranean systems. This raises ethical and legal questions: should nations be allowed to weaponize the Earth’s crust?
The Human Element
Beyond technology, Luckey’s idea forces us to think about the human experience of war. Underground environments are claustrophobic, dark, and isolating. Soldiers would face psychological challenges unlike those in open battlefields. Designing safe, livable subterranean bases would be as much about human resilience as engineering.
Looking Ahead
Whether or not Luckey’s vision comes true, it highlights an important point: the future of warfare is not predetermined. While space may seem like the obvious frontier, other domains—cyber, underwater, and now underground—could prove equally decisive. His comments remind us that innovation often comes from questioning assumptions.
