Castelion, a defense technology startup, reached a $13 billion valuation as it prepares to mass-produce hypersonic missiles, the company announced today. The funding round, completed in August 2026, attracted significant investment from strategic defense partners and venture capital firms, positioning Castelion as a key player in advanced missile technology.
The company secured its latest funding through a combination of private equity and government contracts. Castelion's CEO, Rajiv Malhotra, highlighted the rapid development timeline and the strategic importance of hypersonic weapons in modern defense. The capital will be used to scale manufacturing capabilities and accelerate deployment schedules, with production facilities expanding across multiple sites in the United States and allied countries.
Hypersonic missile technology is a critical area of competition globally, with major powers investing heavily to gain tactical advantages. Castelion's valuation places it among the top defense startups focused on next-generation weaponry, comparable to firms like Raytheon and Lockheed Martin in terms of innovation. The company's advancements could shift defense procurement trends and influence geopolitical balances by providing faster, more maneuverable missile systems.
Castelion plans to begin full-scale production by early 2027, with initial deliveries scheduled for Q2 2027 to U.S. and allied military forces. The company confirmed that its manufacturing contracts currently total over $4 billion, underscoring the scale and urgency of hypersonic missile deployment programs.
