"The mission was successful. The missile hit the target in the Indian Ocean in a perfect way," Defence Research and Development Organisation (DRDO) chief VK Saraswat said.
The successful test of Agni V is a significant achievement for India. The indigenously developed, nuclear-capable missile has a strike range of 5,000 kilometres. It is about 17 metres long, two metres wide and weighs around 50 tonnes. The sophisticated missile travels faster than a bullet and has the capacity to carry 1000 kilograms of nuclear weapons.
Only six countries - including the United States, Russia, United Kingdom, China and France - so far possess this technology. India will break into this exclusive ICBM club once the Agni-V is ready for induction by 2014-2015 - after several more tests.
Tipped to be a "game changer" by experts, Agni V will extend India's reach all over Asia, parts of Africa and parts of Europe. The Agni series of missiles, including Agni-V, is crucial for India's defence vis-a-vis China since Beijing has upped the ante in recent times by deploying missiles in Tibet Autonomous Region bordering India.
Agni-V can be configured to launch small satellites and can be used to even shoot down enemy satellites in orbits. Once fired, it cannot be stopped. It can, however, be launched only after a decision by the Cabinet Committee on Security (CCS).
Defence Minister AK Antony described Agni V's maiden test flight's success as a major milestone. "The nation stands tall today. We have joined the elite club of nations (who possess the ICBM capability)," Mr Antony reportedly told DRDO chief over the phone after the test flight of the missile was declared successful. "The immaculate success of Agni V is a major milestone in the country's missile research and development programme," he said.
Prime Minister Manmohan Singh congratulated DRDO scientists for the feat. "The nation stands together in honouring the scientific community who have done the country proud," he conveyed via twitter.
"DRDO and other organisations have worked tirelessly in our endeavour to strengthen the defence and security of our country. Today's launch represents another milestone in our quest for our security, preparedness and to explore the frontiers of science," he added.
