Prime Toolings, headquartered in Bangalore, unveiled its innovative 12 kN class Rotating Detonation Engine (RDE) for missiles in early August 2025, marking a leap in India’s indigenous defense technology. The RDE, designed for tactical missiles with ranges of 300-500km, enhances fuel efficiency by up to 25% compared to traditional engines and features a compact, lightweight build with no moving parts, reducing both complexity and cost. This technology operates via supersonic detonation waves traveling around an annular chamber, delivering continuous, high-efficiency thrust—unlike classic engines that use subsonic combustion. Recent ground tests have indicated strong operational viability, positioning Prime Toolings as a significant contributor to India’s Atmanirbhar Bharat initiative and the future of advanced missile propulsion systems.
