Explanation:

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.

Statement 1 is correct: 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.

Statement 2 is correct: 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.
• The Army also has the BrahMos supersonic cruise missile in its arsenal, with a stated range of 290-plus kilometres.

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.

Hence both statements are correct.
