Bangalore: A test of the nuclear-capable Agni-III missile will be conducted next year after rectifying a material-related fault that caused the failure of its first trial in July, Defence Research and Development Organisation (DRDO) Director General M Natarajan said today. DRDO scientists have found out the possible fault that caused the failure of the first test of Agni-III missile on July 9 and are rectifying it, Natarajan said. "We have traced the possible fault and are attending to that. It involves certain mechanical modifications...That's going on," he told reporters at a press conference addressed by Defence Minister A K Antony. The problem was material-related and there was no problem in the missile's rocket motor, or control, guidance and navigation systems, he said. The News Pakistan.
