The test-launch, done from Wheeler Island at 8:43 am, off the Odisha coast, for the second time in two years, is seen as a major step in India's efforts to become a regional power that can counter the dominance of China.(Pics: Test-launch of Agni-5)
The Agni-5 is about 17 meters long and weighs 50 tons. It is a three-stage missile designed to carry an over 1 ton warhead with a range of 5,000 kilometers, allowing it the farthest reach among all Indian missiles.

The first test of the Agni-5 missile was conducted on April 19, 2012 when the guidance system - critical in determining the efficiency of missile - worked perfectly.
The development of Agni-5 began in 2009 according to DRDO it will now be rolled into production mode with and induction likely in 2015
Agni-5 gives India the ability to launch nuclear weapons from land at will from any where in India. It will give India the ability to hit back or have second-strike capability even after a nuclear
