India shot down one of its satellites in space with an anti-satellite missile on Wednesday, Prime Minister Narendra Modi said, hailing the country’s first test of such technology as a major breakthrough that establishes it as a space power.

India would only be the fourth country to have used such an anti-satellite weapon after the United States, Russia and China, said Modi, who heads into general elections next month.

“Our scientists shot down a live satellite 300km away in space, in low-earth orbit,” Modi said in a television broadcast.

“India has made an unprecedented achievement today,” he added, speaking in Hindi. “India registered its name as a space power.”

Anti-satellite weapons allow for attacks on enemy satellites, blinding them or disrupting communications, as well as providing a technology base to intercept ballistic missiles.

Such capabilities have raised fears of the weaponization of space and setting off a race between rivals.

After the news, China’s foreign ministry said it hoped all countries “can earnestly protect lasting peace and tranquility in space.” The United States and Russia both declined to make any immediate comment.

In a statement, India’s neighbour and arch-rival Pakistan said space is the “common heritage of mankind and every nation has the responsibility to avoid actions which can lead to the militarisation of this arena.”

Tension flared last month between the nuclear-armed foes after a militant attack in the disputed region of Kashmir.

India has had a space program for years, making earth imaging satellites and launch capabilities as a cheaper alternative to Western programs.

It successfully sent a low-cost probe to Mars in 2014 and plans its first manned space mission by 2022.

The latest test, conducted from an island off its east coast, was aimed at protecting India’s assets in space against foreign attacks, the government said.

“The capability achieved... provides credible deterrence against threats to our growing space-based assets from long-range missiles, and proliferation in the types and numbers of missiles,” the foreign ministry said in a statement.

The three-minute test in the lower atmosphere ensured there was no debris in space and the remnants would “decay and fall back on to the earth within weeks”, the ministry added.

Brahma Chellaney, a security expert at New Delhi’s Centre of Policy Research, said the United States, Russia and China were pursuing anti-satellite weapons.

“Space is being turned into a battlefront, making counter-space capabilities critical. In this light, India’s successful ‘kill’ with an anti-satellite weapon is significant.”

The Indian PSLV rocket Microsat-R launched in January.

China destroyed a satellite in 2007, creating the largest orbital debris cloud in history, with more than 3,000 objects, according to the Secure World Foundation.

China’s test spurred India to develop its anti-satellite capability, said Ajay Lele, a senior fellow of the government-funded Institute for Defence Studies and Analyses in New Delhi.

Indian defence scientists had sought political approval for live tests but successive governments had baulked, fearing international condemnation, an Indian defence official said.

A spokesperson for the US mission in Geneva, which handles disarmament issues, had no immediate comment.

US a pioneer

The United States ran the first anti-satellite test in 1959, when satellites themselves were rare and new.

Bold Orion, a nuclear-tipped ballistic missile repurposed to attack satellites, was launched from a bomber and passed close enough to the Explorer 6 satellite to destroy it if the nuclear warhead had been live.

In the 1960s and early 1970s, the Soviet Union tested a weapon that would be launched into orbit, approach enemy satellites and destroy them with an explosive charge, according to the Union of Concerned Scientists.

In 1985, the United States tested the ASM-135, launched from an F-15 fighter, destroying an American satellite called Solwind P78-1.

There were no tests for more than 20 years, until China entered the anti-satellite arena in 2007.

The following year, the United States used a ship-launched SM-3 missile to destroy a defunct spy satellite in Operation Burnt Frost.

Modi’s Hindu nationalist-led government has taken a strong position on national security, launching air strikes last month on a suspected militant camp in Pakistan that spurred retaliatory raids.

Although he faces criticism for failing to deliver on high economic growth and create jobs, a hawkish position on security should help Modi at the ballot box, pollsters say.

The leader of the main opposition Congress party, Rahul Gandhi, congratulated defence scientists, but took a dig at Modi for the announcement on a day that commemorates theatricals.

“I would also like to wish the prime minister a very happy World Theatre Day,” Gandhi said.

The leader of another opposition group said it would complain to the Election Commission that Modi was trying to build political capital using the space program.

A concern for India is that China could help its old ally Pakistan neutralise any advantage.

“I don’t think Pakistan has acquired that level of accomplishment yet by itself, but Pakistan is no longer seen alone,” said Uday Bhaskar, director of the Society for Policy Studies, another Delhi think tank.

“Pakistan and China have a very deep strategic kind of partnership. So some kind of sharing of capabilities can’t be ignored.”
