Pralay Missile | 23 Dec 2021

Why in News

Recently, the Defence Research and Development Organisation (DRDO) has successfully conducted maiden flight test of a new indigenously developed surface-to-surface missile ‘Pralay’.

  • The missile was tested from the Dr A.P.J. Abdul Kalam Island off the coast of Odisha.

Key Points

  • About: Pralay' is India's first conventional quasi-ballistic missile and is an answer to any conventional missile attack from northern or western borders.
    • A quasi-ballistic missile has a low trajectory, and while it is largely ballistic, it can maneuver in flight.
    • The missile has been developed in a way that it is able to defeat the interceptor missiles and also has the ability to change its path after covering a certain range mid-air.
    • It is powered with a solid propellant rocket motor and many new technologies.
    • The missile guidance system includes state-of-the-art navigation system and integrated avionics.
  • Background: It is a derivative of the Prahaar missile programme, which was first tested in 2011.
    • Prahaar is a surface-to-surface missile with a range of 150 km.
    • Primary objective is to bridge the gap between the unguided Pinaka multi-barrel rocket launcher and the guided Prithvi missile variants.
  • Range: The missile has a range of 150-500 kilometre and can be launched from a mobile launcher.
    • Pralay will be the longest-range surface-to-surface missile in the inventory of the Army.
  • Significance: It will completely change the tactical battlefield dynamics and India will have two conventional missiles with long range.
    • The BrahMos will be a cruise option and this one will be the ballistic option.
Ballistic Missile vs Cruise Missile
Ballistic Missile Cruise Missile
  • Travel in projectile motion and trajectory depends on gravity, air resistance and Coriolis Force.
  • Comparatively follows a straight trajectory of motion.
  • Leave the earth’s atmosphere and re enter it.
  • The flight path is within the earth’s atmosphere.
  • Long-range missiles (300 km to 12,000 km)
  • Short range missiles (range upto 1000 km)
  • E.g. Prithvi I, Prithvi II, Agni I, Agni II and Dhanush missiles.
  • E.g. BrahMos missiles
