India successfully test-fired nuclear-capable ballistic missile Agni-5

What in news:

         India successfully test-fired nuclear-capable ballistic missile Agni-5.

About news:

         During the trial, the flight performance of the missile was tracked and monitored by radars, tracking instruments and observation stations.

         The high-speed onboard computer and fault-tolerant software, along with robust and reliable bus guided the Agni-5 missile flawlessly.

Agni 5 missile programme

         The missile is programmed in such a way that after reaching the peak of its trajectory, it turns towards the earth to continue its journey to the target with an increased speed, due to the earth's gravitational pull.

         As the missile enters the earth's atmosphere, the atmospheric air rubbing its outer surface skin raises the temperature to beyond 4,000 degree Celsius.

         However, the indigenously-designed and developed heat shield maintains the inside temperature at less than 50 degree Celsius.

         Finally, commanded by the onboard computer with the support of laser gyro-based inertial navigation system, micro inertial navigation system (MINS), fully digital control system and advanced compact avionics, the missile hit the designated target point accurately, meeting all mission objectives.

         All the radars and electro-optical systems along the path monitored the parameters of the missile and displayed them in real time.

         The nuclear-capable missile is expected to be inducted into India's Strategic Forces Command soon

         This was its third successful test this year and the last test was held in June 2018.

         The first test of Agni-5 was conducted on April 19, 2012.
