India today successfully test-fired its nuclear-capable Agni-III ballistic missile from the Wheeler Island off Orissa coast. The endogenously developed surface-to-surface missile was tested from a rail mobile launcher near Dhamara, about 100 kilometers from Balasore this morning. Defence sources said, all mission parameters of the missile with a range of more than 3,000 kilometers were met. This is the fourth flight test in the Agni-III series carried out to establish the repeatability of the missile's performance. The entire trajectory of today's trial was monitored through various telemetry stations, electro-optic systems and sophisticated radars located along the coast, in Port Blair and by Naval ships anchored near the impact point in the down range area for data analysis. Agni-III missile is powered by a two-stage solid propellant system. With a length of 17 metres, the missile's diameter is 2 metres and launch weight is 50 tonnes. It can carry a payload of 1.5 tonnes which is protected by carbon-carbon all composite heat shield.
