While drones get the headlines, operators on the front lines in Ukraine identified Starlink as the most critical technology. This reveals that the foundational layer for future conflict is resilient, decentralized communication, which enables all other advanced systems to function in contested environments.
Unlike early defense startups aiming to become the next prime contractor, a new wave of companies is focused on rebuilding the industrial base. They act as critical suppliers of innovation, AI, and components to legacy primes like Lockheed Martin, viewing them as customers and partners rather than just competitors.
Beyond SpaceX's products, its most significant impact is creating a diaspora of engineers skilled in Musk's "build for production" methodology. These alumni are now founding new defense companies, applying lessons on speed and cost that are absent from traditional engineering education and corporate environments.
Investing in a hypersonic weapons company, once a career-ending move in Silicon Valley, is now seen as a crucial act of deterrence. This rapid cultural reversal, catalyzed by geopolitical events, signifies a profound sea change in the tech industry's values and its relationship with national security.
The pendulum swing from software back to hardware and defense is mirrored by a change in the dominant engineer archetype. The era of the "Facebook generation" coder is giving way to a resurgence of the "Palmer Luckey" type—engineers who work with physical systems and build with their hands, echoing Silicon Valley's original pioneers.
Silicon Valley investors are backing companies building cheap, quickly manufacturable, and expendable ("attritable") systems like autonomous boats. The core innovation is the ability to rapidly scale production from one to 10,000 units, fundamentally changing warfighting economics away from expensive, long-cycle platforms like aircraft carriers.
While the US can assemble advanced drones, a significant national security risk lies in the supply chain for their basic components, many of which come from China. The strategic imperative is to "shift left" and onshore the manufacturing of these foundational parts to secure the entire defense industrial base, not just the final product.
