AI Dominates the Headlines, but Defense Tech Is Gaining Speed
🔦 Spotlight
Hello, Los Angeles!
This week, DeepSeekAI has been dominating the tech conversation. The Chinese AI startup’s chatbot app surged to the No. 1 spot on the App Store, drawing both excitement and scrutiny. Supporters see its open-weight model as a potential game-changer, offering developers more flexibility compared to closed AI systems like OpenAI’s. But the rapid rise has also raised questions about security, data governance, and global AI competition. Whether DeepSeek will be a long-term disruptor or just a momentary sensation remains to be seen, but one thing is clear—AI remains the tech industry’s driving force.
But while AI continues to dominate headlines, another sector is quietly making waves—defense technology. And one LA-based startup just secured a major endorsement from investors and the U.S. government.
Castelion’s Hypersonic Bet—Can It Outrun the Defense Industry’s Red Tape?

El Segundo-based Castelionjust raised$100 million to accelerate its mission to build hypersonic weapons faster, cheaper, and at scale. The financing—$70 million in equity (led by Lightspeed Venture Partners with participation from a16z, Lavrock Ventures, Cantos, First In, BlueYard Capital, and Interlagos) and $30 million in venture debt (from Silicon Valley Bank)—is the latest sign that venture capital sees national security startups as a high-growth opportunity.
Unlike traditional defense contractors, Castelion is operating like a fast-moving startup, not a slow-moving government supplier. Founded by former SpaceX engineers, the company is applying an iterative, test-heavy approach to building long-range hypersonic strike weapons—which travel at speeds exceeding Mach 5 (3,800+ mph) and are designed to evade modern missile defenses.
Not Just VC-Backed—The U.S. Military is Betting on Castelion Too
While the $100 million raise is a major milestone, Castelion already has funded contracts with the U.S. Navy, U.S. Air Force, and U.S. Army. These contracts are focused on hypersonic technology development and scaled manufacturing, areas where the military has struggled to move quickly due to bureaucratic delays and reliance on traditional defense giants.
To prove it can execute, Castelion recently successfully launched a low-cost ballistic missile from a self-built launcher in Mojave. Now, with both government contracts and venture capital behind it, the company is pushing forward on more flight tests and building out its scaled production capabilities.

With rising geopolitical tensions and an increasing focus on faster, cost-effective deterrence, Castelion is positioning itself as a new kind of defense player—one that moves at startup speed. Whether it can sustain that pace while navigating the complexities of government procurement remains to be seen, but one thing is clear: the future of defense tech isn’t just about who can build the best weapons—it’s about who can build them fast enough.
