Hermeus raises $350M to build unmanned hypersonic fighters

Hermeus, a pioneering defense startup based in Los Angeles, has successfully raised $350 million to advance its development of what it claims to be the fastest unmanned aircraft. The recent funding round has elevated the company's valuation to an impressive $1 billion. The financing included $200 million in equity, predominantly led by Khosla Ventures, with participation from established investors such as Canaan Partners, Founders Fund, In-Q-Tel, and RTX Ventures. New contributions also came from the venture arm of media giant Cox Enterprises and Destiny Tech100, a publicly traded investment management firm. Additionally, the remaining $150 million was secured through debt financing, which co-founder and CEO AJ Piplica indicated would help the startup maintain control over its growing capital structure. Piplica explained that Hermeus, which is focused on expanding its manufacturing capabilities, aims to finance a significant portion of its expenditures without diluting ownership. This funding comes at a time when investments in defense technology are surging, with venture capital flows exceeding $9 billion globally last year. However, Hermeus's success is attributed not only to favorable market conditions but also to a strategic pivot in its technical development. Initially, the company invested in creating its own engine. Following discussions with RTX Ventures, they shifted direction to collaborate with RTX subsidiary Pratt & Whitney to adapt the F100 engine for their hypersonic aircraft. This partnership has placed Hermeus on a more efficient path to achieving its goals while facilitating government contracts. Instead of solely focusing on developing a Mach 5 aircraft, the team has diversified its approach, according to President Zach Shore. This strategy not only accelerates their timeline but also enhances the business's economic viability and addresses immediate needs from the Department of Defense. Recently, Hermeus successfully conducted a test flight of a demonstrator aircraft comparable in size to an F-16 fighter. The company is now aiming for its next iteration to achieve supersonic speeds, with plans for a third aircraft already underway. Piplica emphasized that this rapid prototyping methodology is rare in aviation, likening their iterative process to SpaceX’s approach to vehicle development. A key challenge for Hermeus remains talent acquisition, as there is a scarcity of professionals experienced in building new full-scale aircraft regularly. To address this, the new funding will also enable the company to expand its workforce, which is nearing 300 employees. With two successful test flights under their belt, Piplica acknowledged the inevitability of setbacks during the prototyping process, reiterating the need for robust testing and development to meet their ambitious goals.
