India claims it is in space's "super league" after shooting down a low-orbit satellite in a missile test.
Prime Minister Narendra Modi made an unexpected address to the nation, saying that India is now an "established space power".
According to Mr Modi, with the successful launch of an anti-satellite missile (ASAT), India has become only the fourth country after the US, China and Russia to have this technology.
The timing of the announcement has however raised questions.
With less than two weeks to go for a national election, the opposition has accused Mr Modi of trying to score political points and take credit for the achievements of the country's space agency.
