Indian Air Force fighters would soon be equipped with special gadgets for production of oxygen while in the air enabling them to be airborne for longer period and carry extra payload. Developed by Defence Research and Development Organisation (DRDO), the On Board Oxygen Generation System (OBOGS) allows pilots to fly without the help of heavy oxygen cylinders they usally carry for high altitudes and long duration sorties. W Selvamurthy, Chief Controller, Life Science, of DRDO, said, the Aeronautical Development Agency has started the ground integration process of OBOGS in the Technology Demonstrator version of the Light Combat Aircraft (LCA) Mark-II. He said, after LCA it will be integrated in all the frontline aircraft of the Indian Air Force. So far only three countries including, United States, Russia and France have successfully integrated the OBOGS technology in their Air force.
