DRDO chief Vijay Kumar Saraswat, who is also the scientific advisor to the Union governmentâ€™s ministry of defence, said future warfare would be on a remote level, without contact and minus conventional weapons. He underlined the need to develop systems like high-power lasers and â€˜guidedâ€™ energy weapons. Dr Vijay Kumar Saraswat was conferred a doctorate in Science by the KL University during its second convocation in Vaddes-waram village of Guntur district on Monday. Speaking on the occasion he said, the defence scientists had made great strides in the development of Micro electro mechanical systems-based censor technologies, smart materials, Network Centric Warfare, Nano- materials/nano composites, nano fuels and nano censors. Dr Saraswat said that another incredible achievement of DRDO was the indigenously developed light combat aircraft Tejas. Describing the development of the first nuclear submarine, INS Arihant, as an engineering â€˜marvelâ€™, he pointed out that with its launch, India had joined the exclusive club of similar six countries. The DRDO scientists are now working for the development of scramjet-propelled aircraft required for hypersonic flight, which could reach New York from Delhi in an hour. He said â€œDemand for skilled engineers and technologists will increase in the coming years in the country, with science and technology more actively pursued.â€ He suggested that the country introduce schemes which would ensure more fluid collaborations between scientists, technologists and industry, academic institutions and research and development laboratories. Addressing the university students and faculty, he said the mission of the DRDO is to design and develop state-of-the-art defence systems and technologies required for the country.
