Hermeus, a defense startup, has raised $350 million to advance its unmanned hypersonic aircraft technology, achieving a valuation of $1 billion. The funding includes $200 million in equity financing led by Khosla Ventures and $150 million in debt. This influx of capital comes as venture investments in defense tech surged to over $9 billion last year. Hermeus has shifted its strategy to collaborate with RTX subsidiary Pratt & Whitney to modify the F100 engine for its aircraft, streamlining development. The startup aims to build a Mach 5 aircraft while also satisfying immediate Department of Defense demands. Recently, Hermeus successfully flew a demonstrator aircraft comparable in size to an F-16. The company plans to continue rapid prototyping, similar to SpaceX's approach in aerospace.

Key Points: • Hermeus raised $350 million to develop hypersonic unmanned aircraft. • The startup's valuation has reached $1 billion following this funding round. • Collaboration with Pratt & Whitney is expected to accelerate aircraft development.
