DRDO conducts high-altitude trials of Integrated Life Support System for LCA Tejas

The Defence Bio-Engineering & Electro Medical Laboratory (DEBEL), a Bengaluru-based lab under the Defence Research and Development Organisation (DRDO), successfully conducted high-altitude trials of the Indigenous On-Board Oxygen Generating System (OBOGS)-based Integrated Life Support System (ILSS) for the LCA Tejas aircraft, on March 04, 2025.

The OBOGS-based ILSS is a cutting-edge system designed to generate and regulate breathable oxygen for pilots during flight, eliminating dependence on traditional liquid oxygen cylinder-based systems. Performance evaluations covered critical aspects such as oxygen concentration, demand breathing, availability of 100% oxygen, aerobatic maneuvers at required altitudes for full functional testing of Anti – G Valve, Breathing Oxygen System (BOS) ON during taxying, Take off, Cruise, G turns and rejoin approach & landing. Following flight clearance from Centre for Military Airworthiness & Certification (CEMILAC), the system successfully met all specified parameters.

Raksha Mantri Shri Rajnath Singh congratulated DRDO, IAF, Public Sector Undertakings, and industry partners on this remarkable achievement, emphasising that this development reinforces India’s commitment to cutting-edge defence technologies and aligns with the vision of ‘Viksit Bharat 2047.’
