The 1500 kilogram missile has a length of about six meters and flies like a conventional plane powered by an engine and has small wings. Once the missile achieves a designated altitude and velocity, the booster motor is separated and the engine automatically switches on taking further propulsion. The missile's wing opens up mid-way in its flight by the commands generated by the sophisticated on-board computer for stabilising the flight path.
'Nirbhay' is to be tracked with the help of ground based radars and IAF aircraft all along its trajectories from the lift off to splash down.
The cruise missile took off from a specially designed launcher from the launch complex-3 of the Integrated Test Range or ITR at Chandipur, near Balasore, at about 11.20 am, Defence Research and Development Organisation or DRDO sources said.
"All initial critical operations of the trial such as blast of the sophisticated missile are successful as it moved up in its trajectory," a DRDO scientist said.
All these trials were conducted from Chandipur base along the Odisha coast.
