A second test flight of long range, nuclear-capable Agni-V missile might take place on September 15 from Wheeler Island on Odisha's coast, if weather permits.
"If everything goes according to plan and weather condition allows for a smooth launch, the test might be taken up on September 15 from launch pad-4," an official of Defence Research and Development Organisation said on Friday.
Scientists and officials associated with the project were quite hopeful of a good performance as the first trial on April 19, 2012 was a total success.
The official said, "Preparation in the Integrated Test Range has reached a final stage and the missile and its sub-systems have been put to last minute check. As it is a developmental trial, the missile system and battery of networks associated with the test are to be validated before going for final launch."
The surface-to-surface, three stage solid propellant missile is designed to deliver nuclear warheads of 1000 kg at a range of 5000 km, the sources said.
Standing about 17 meter tall, the state-of-the-art missile could take off from a mobile launcher with or without a canister system.
