Addressing DRDO fraternity on the occasion of National Technology Day here, he said India found "new respect" because of the tests, while the country's scientists and engineers got their due recognition.
"In terms of capabilities we have never been less than anyone else in the world. What we need is confidence in our own capabilities," Chander said.
Highlighting some key achievements he said that DRDO crossed the intercontinental barriers with Agni V, becoming one of the four nations in the world possessing a multi-level strategic deterrence capability.
Recollecting the struggles and challenges posed by more and more technology denials as the impact of India achieving nuclear capabilities, he mentioned how ongoing interactions by western countries were withheld, forcing India to indigenously develop the technologies.
