'The surface-to-surface intermediate range missile was test-fired from a mobile launcher' at 9 am from the Integrated Test Range (ITR) at Wheeler Island, about 100 km from here,' defence sources said.
Christened 'Agni-II Prime', the new missile is a two- stage weapon system powered by solid propellant. It is 20 metres long and launch weight is 17 tonnes. It can carry one tonne pay-load.
A Defence Ministry spokesman said in Delhi that from now on, the missile will be called 'Agni-IV'. Describing the test-firing as 'successful', defence
sources said the missile’s exact performances will be known after all data was collected and analysed from different telemetry and tracking stations as well as naval ships positioned near the terminal point.
'The indigenously developed new variant of 'Agni-II' series missile would have better accuracy and improved range', the sources said.
'While the Agni-II missile has a strike range of 2000 km and Agni-III can hit a target at a distance up to 3500 km, this new variant with a strike range of 3000 km would bridge the gap between Agni-II and Agni-III,' they said.
In terms of accuracy, 'some more improved features have been incorporated in it,' a DRDO scientist said.
The first developmental trial of Agni-II Prime, conducted on 10 December, 2010, had failed due to some technical problem in the control system. It deviated from its trajectory within seconds of its lift off from the same base and had plunged into the sea.
