Strategic Focus: India’s Rocket Revolution: The Astrobase Unveils Nation’s First 80-Tonne FFSC Methane Engine Built Entirely via Industrial 3D Printing

In a monumental leap for India’s private space sector, space-tech startup The Astrobase Space Technologies has pulled back the curtain on the nation’s first fully integrated 80-tonne-class Full-Flow Staged Combustion (FFSC) rocket engine. Boasting architecture akin to SpaceX’s famed Raptor engine, this cutting-edge propulsion system runs on liquid oxygen and methane, laying the technical foundation for upcoming reusable launch vehicles. Designed to deliver a massive 800 kN of thrust, the engine utilizes the advanced full-flow staged combustion cycle—widely considered the holy grail of modern rocket propulsion due to its high efficiency and propellant utilization. According to co-founder Neeraj Khandelwal, the entire system was conceptualized and manufactured completely in-house in India, leveraging the company’s massive industrial metal 3D printer to streamline complex geometries and reduce production bottlenecks. With the manufacturing milestone successfully achieved, momentum now shifts to rigorous testing phases:

Industry observers have hailed the achievement as a rare global feat, cementing India’s growing prowess in deep-tech space engineering and independent propulsion development.
