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

The Defence Bio-Engineering and Electro Medical Laboratory DEBEL, a Bengaluru-based lab under the Defence Research and Development Organisation (DRDO) has 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.

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. The ILSS underwent rigorous testing on the LCA-Prototype Vehicle-3 aircraft of Hindustan Aeronautics Limited and Aeronautical Development Agency, meeting stringent aeromedical standards in varied flight



conditions, including altitudes of up to 50 thousand feet Above Mean Sea Level and high-G manoeuvres.

Defence Minister Rajnath Singh has congratulated DRDO, the Indian Air Force, 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.

Secretary, Department of Defence Research and Development and Chairman DRDO Dr Samir V Kamat also lauded the DRDO team, the IAF, and industry partners for their contributions towards the successful high-altitude trial of the Indigenous ILSS for LCA Tejas.
