EL SEGUNDO, Calif.–(BUSINESS WIRE)–Castelion – a new defense manufacturer helping America and its allies preserve peace through deterrence with long range hypersonic strike weapons – announced today it has raised $100M in debt and equity financing.

With rising tensions in the Indo-Pacific, the United States and its allies need a non-nuclear deterrent capability. Affordable, mass-produced hypersonic long-range strike weapons are required to build a decisive combat power advantage and deter future aggression.

The Series A financing round was led by Lightspeed Venture Partners, with participation from a16z, Lavrock Ventures, Cantos, First In, BlueYard Capital, and Interlagos. The financing includes $30M in Venture Debt financing provided by Silicon Valley Bank, with final close expected in February.

Funding will be used to continue Castelion’s rapid flight test campaign and invest in scaled manufacturing infrastructure for key missile subsystems.
