• DRDO successfully tested the Indigenous ILSS for LCA Tejas on high-altitude missions.
• The system generates breathable oxygen for pilots, eliminating the need for traditional liquid oxygen cylinders.
• The trials were conducted under extreme conditions, with altitudes up to 50,000 feet.
• The system was tested during aerobatic maneuvers, take-offs, cruises, and landings.
• ILSS performance met all critical aeromedical standards, ensuring reliable oxygen supply during flights.
• The system integrates 10 Line Replaceable Units, including the Low-Pressure Breathing Regulator and Emergency Oxygen System.
• The successful trials affirm India’s growing self-reliance in aerospace technologies with 90% indigenous content.
• The system has been cleared by CEMILAC, confirming its reliability and safety.
• Developed by DRDO and produced in partnership with L&T, the system may also be adapted for use in MiG-29K.
• Defence Minister Rajnath Singh praised the achievement as a step towards India’s vision of ‘Viksit Bharat 2047.’
