    India test-fires Nirbhay missile successfully

    India has successfully test fired cruise missile 'Nirbhay' which can travel at treetop level and evade Radars.
    It can also carry warheads of up to 300kg, including nuclear weapons and is a potent weapon of offence.
    The 1,500 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.
    '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. This was the fifth experimental test of the homegrown missile system.
    It was successfully test fired from the Integrated Test Range (ITR) at Chandipur along the Odisha coast. This was the fifth experimental test of the homegrown missile system. Out of the four earlier trials since its maiden launch in 2013, only one was successful.
    Describing the trial a success, a defence statement said the Defence Research and Development Organisation (DRDO) achieved yet another feat, the successful test flight of 'Nirbhay' which can be deployed from multiple platforms.
    The missile has the capability to loiter and cruise at 0.7 Mach, at altitude as low as 100 m. It took-off in a programmed manner and all critical operations like launch phase, booster deployment, engine start, wing deployment and other operational parameters demonstrated through autonomous way point navigation, the statement said.
    The guidance, control and navigation system of the missile is configured around the indigenously designed Ring Laser Gyroscope (RLG) and MEMS based Inertial Navigation System (INS) along with GPS system, it said. The missile cruised for 50 minutes, achieving the range of 647 km. It was tracked with the help of ground-based radars and other parameters were monitored by indigenous telemetry stations developed by the DRDO, the statement said.
    According to a DRDO scientist associated with the project, powered by a solid rocket motor booster developed by the Advanced Systems Laboratory (ASL), the 'Nirbhay' missile has an operational range of 1,000 km. It can travel with a turbofan or turbojet engine and is guided by a highly advanced inertial navigation system indigenously developed by the Research Centre Imarat (RCI), he said. After the missile achieves designated altitude and velocity, the booster motor is separated and the engine automatically switches on for further propulsion, the scientist said. He said, "Mid-way in its flight, the missile's wing opens up by the commands generated by the sophisticated on-board computer for stabilising the flight path."
    The health parameters of the vehicle were monitored at indigenous telemetry stations by a team of professionals from DRDO's ITR and LRDE (Electronics and Radar Development Establishment). The two-stage missile is six metre long, 0.52 metre wide with a wing span of 2.7 metre. It can carry a warhead of 200 kg to 300 kg at a speed of 0.6 to 0.7 Mach. Its launch weight is about 1,500 kg, DRDO sources said. The maiden test flight of 'Nirbhay', on March 12, 2013, had to be terminated midway for safety reasons as a component malfunctioned.
    However, the second launch on October 17, 2014 was successful. In the next trial on October 16, 2015, the missile deviated from its path after covering 128 km. The last test- flight on December 21 last year had to be aborted after 700 seconds of the missile's test flight as it deviated from its designated path. All these trials were conducted from the same base at Chandipur ITR.
