RAS question
The Defence Research and Development Organisation (DRDO) developed the 'Pralay' missile. What type of missile is it?
Correct answer: (C) Surface-to-surface quasi-ballistic tactical missile.
DRDO's Pralay is a solid-propellant, surface-to-surface quasi-ballistic tactical missile with a stated range of 150-500 km.
Explanation
Pralay is classified as a surface-to-surface quasi-ballistic tactical missile because it is launched from the surface and follows a quasi-ballistic trajectory towards its target. The PIB release on its maiden flight test states that DRDO successfully tested the indigenously developed surface-to-surface missile from Dr A P J Abdul Kalam Island, and that the missile followed the desired quasi-ballistic trajectory with a high degree of accuracy. It is powered by a solid-propellant rocket motor, has a 150-500 km range, and can be launched from a mobile launcher. For the tactical battlefield angle, Pralay can manoeuvre mid-course to evade interceptors and is based on Prithvi Defence Vehicle technology.
Why the other options are wrong
- (A) An air-to-air missile is launched from an aircraft against an airborne target, whereas Pralay is described as a surface-to-surface missile.
- (B) A torpedo is an underwater weapon, while Pralay is a missile tested on a quasi-ballistic surface-to-surface trajectory.
- (D) An anti-tank guided missile is meant for armoured targets; Nag and HELINA serve that role, not Pralay.
Concept
This tests defence technology classification, especially how launch platform, trajectory and battlefield role determine missile type. RAS repeats such items because DRDO systems are a standard Science and Technology current-affairs theme.
