Czech firm Nebesa Aerospace unveils suborbital drone platform for defense testing

Bottom line

Czech firm Nebesa Aerospace has unveiled the NEBESA suborbital drone platform, capable of reaching 110 km altitude and 3.5 Mach, designed for defense testing and aerodynamics research.

Why it matters

The NEBESA platform provides a new tool for European defense firms to test high-speed and high-altitude systems, potentially reducing reliance on US or Russian facilities and accelerating development of advanced aerospace technologies.

Czech firm Nebesa Aerospace has presented the NEBESA suborbital drone platform. The vehicle reaches an altitude of 110 km and a speed of 3.5 Mach, carrying a 25 kg payload. It uses a liquid rocket engine and is designed for defense testing, aerodynamics, and material research without requiring a traditional spaceport. This platform offers a cost-effective alternative for high-altitude testing of materials and systems.
