Former ISRO Chairperson G Madhavan, who joined the Bharatiya Janata Party (BJP) last year, said that India had the anti-satellite missile capability more than a decade ago, but there was "no political" will at the time to demonstrate it.
However, according to The Indian Express, Nair had in 2007 admonished China for shooting down an ageing weather satellite, adding that it was against international convention.
He had headed the ISRO, Space Commission and was Secretary in the Department of Space from 2003 to 2009. Nair joined the BJP in October 2018.
The prime minister on Wednesday announced India had demonstrated the capability by shooting down a live satellite, describing it as a rare achievement that puts the country in an exclusive club of space superpowers.
India is only the fourth country to have such a specialised capability after the US, Russia and China.
