(CNN) Prime Minister Narendra Modi said India has successfully conducted an anti-satellite missile test that put the country in a league of global "space powers."

In a national address Wednesday, Modi said India had achieved a "historic feat" by shooting down its own low-orbit satellite with a ground-to-space missile in three minutes.

Only three other countries -- the US, Russia and China -- have the capabilities to use an anti-satellite missile.

Lt. Gen. David D. Thompson, vice commander of US Air Force Space Command, confirmed the test took place and said the US was aware of the possibility that India would conduct it because of several announced flight bans and other information.

US forces were still tracking 270 different objects in the debris field from the test, but he said the number is set to grow as they collect more data. Thompson said the International Space Station was not at risk.
