Vinod Khosla, founder of Khosla Ventures, has reaffirmed his support for Hermeus, a startup focused on developing high-speed military aircraft, by leading a $350 million Series C funding round. This investment pushes Hermeus' valuation to $1 billion, with $200 million in equity and $150 million in debt. The funds will accelerate the development of its Quarterhorse testbed and Darkhorse drone, enhancing its manufacturing capabilities with a new facility in El Segundo, California. Khosla expressed confidence in Hermeus' strategy, noting the company's potential to address critical capability gaps in modern warfare. Founded in 2018, Hermeus aims to create aircraft that can fly above Mach 5 and is competing against other notable companies in the high-speed aerospace sector, such as Boom Supersonic and Spike Aerospace.
