India plans the maiden test flight this week of its longest-range nuclear-capable missile, which can travel more than 3,100 miles.
The spokesman for the country's Defense Research and Development Organization Ravi Gupta said that the Agni V rocket could be launched between today and Friday, and that it's the most advanced missile so far
In November, India successfully tested the fourth version of Agni, meaning "fire" in Hindi, with a range of 3,500 km.
According to Indian defense authorities, built years earlier, Agni I, could travel 700 km.
India says that it pursues no aggressive designs and that its military program is based on building a credible minimum deterrent with a "no-first-use" policy.
Gupta added that their missiles are purely for deterrence.
