India today successfully test-fired its nuclear-capable strategic ballistic missile Agni-IV with a strike range of 4000 km as part of a user trial from a test range off Odisha coast. 

Supported by a mobile launcher, the surface-to-surface missile was flight tested from launch complex-4 of the Integrated Test Range (ITR) at Dr Abdul Kalam Island, formerly known as Wheeler Island, at about 11.55 hours, Defence Research and Development Organisation (DRDO) sources said.

The successful trial of Agni IV came close on the heels of a similar test on December 26, 2016 of long range missile Agni 5 which was successfully carried out from the same launch site. 

Describing the trial as successful, they said this was the 6th trial of the indigenously developed Agni-IV missile which met the mission objectives. The last trial conducted by the specially formed strategic force command (SFC) of Indian Army on November 9, 2015 was also successful.
