RAS question
DRDO's 'DURGA-2' project relates to:
Correct answer: (C) Directed energy weapon (laser-based).
DRDO's DURGA II project relates to a laser-based directed-energy weapon, formally expanded as Directionally Unrestricted Ray-Gun Array.
Explanation
DURGA II is not a platform such as a submarine, satellite, or missile; it is DRDO's high-power laser weapon programme. DURGA II expands as Directionally Unrestricted Ray-Gun Array and functions as a lightweight directed-energy weapon. Directed-energy weapons use focused energy, including lasers, microwaves, or particle beams, to incapacitate or destroy targets rather than relying on physical impact or explosive payloads. DURGA II therefore belongs to DRDO's directed-energy work as a laser-based defence weapon system.
Why the other options are wrong
- (A) A submarine is a naval platform, whereas DURGA II is a lightweight directed-energy laser weapon programme.
- (B) A communication satellite is used for transmitting signals, while DURGA II belongs to DRDO's defence weapon work, not space communication.
- (D) A missile system relies on a projectile or payload, whereas DURGA II is a directed-energy weapon using focused energy such as lasers.
Concept
RAS Science and Technology covers emerging defence technologies, especially directed-energy weapons. DRDO projects often recur in RAS through direct links between a project name and its technology domain.
