♦ 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.  

♦ The OBOGS-based ILSS is a state-of-the-art system designed to generate and regulate breathable oxygen for pilots during flight.

♦ This system eliminates the need for traditional liquid oxygen cylinder-based systems, providing greater efficiency and safety. The ILSS underwent rigorous testing on the LCA-Prototype Vehicle-3 aircraft, developed by Hindustan Aeronautics Limited (HAL) and the Aeronautical Development Agency (ADA). 

♦ The system was tested under extreme conditions, including altitudes of up to 50,000 feet above mean sea level and high-G maneuvers, to ensure its performance met stringent aeromedical standards. 

♦ Manufactured by L&T as a Development cum Production Partner, the system represents a remarkable collaboration between DRDO and Indian defence industries. Notably, the ILSS has 90% indigenous content, reflecting India’s growing self-reliance in aerospace technology. With suitable modifications, the system can be adapted for use in other aircraft, such as the MiG-29K.
