# Mumbai startup cracks missile cooling tech, breaks Western monopoly 2026-08-10T17:56:22+00:00 | Governance | Indian Opinion Desk Corroboration: 1 independent outlet A Mumbai startup has indigenously developed a 10-gram cooling technology for missile seekers, breaking a Western monopoly held by the US, France and Israel. The Techno Defence Pvt Ltd’s ‘Joule-Thomson Cooler’ rapidly cools infrared sensors to -196°C, enabling missiles to track targets accurately. Co-owner Dr Pravin Salinkar, an IIT Bombay alumnus, received DRDO funding in 2020 and handed over the device for successful trials by 2023-24. The component is controlled under the Missile Technology Control Regime. The company is now in export talks with a foreign country, but special permits are needed. ## Coverage - thehindubusinessline.com Tags: defence innovation, DRDO, indigenous manufacturing, missile technology, MTCR, startup Canonical: https://indianopinion.org/mumbai-startup-cracks-missile-cooling-tech-breaks-western-monopoly/ License: Summary and commentary (c) Indian Opinion, reusable with attribution.
