Difficulty: MediumDefense and Nuclear Technology

Consider the following statements regarding 'Rudram-1', India's indigenously developed missile system:

1. It is India's first indigenous anti-radiation missile, designed to target and destroy enemy radar and communication tracking installations.
2. It uses a liquid-fuel ramjet engine to sustain supersonic propulsion throughout its flight path.
3. It is integrated onto Su-30MKI fighter aircraft and operates using a passive homing head seeker.

Which of the statements given above are correct?

  1. 1 and 3 onlyAnswer
  2. B
    1 and 2 only
  3. C
    2 and 3 only
  4. D
    1, 2 and 3

Answer

1 and 3 only
Rudram-1 is India's first indigenously developed anti-radiation missile (NGARM), created by DRDO for air-to-surface strikes against enemy radar and communication infrastructure. It is deployed on Su-30MKI fighter jets and guided by a passive homing head. Its propulsion uses a dual-pulse solid rocket motor rather than a liquid-fuel ramjet engine. Therefore, statements 1 and 3 are correct.

Step-by-Step Solution

1
Analyze Statement 1 regarding the operational role of Rudram-1.
Rudram-1 was developed by DRDO as India's premier Next Generation Anti-Radiation Missile (NGARM) to neutralize enemy radio-frequency sources, surveillance radars, and communication sites. Thus, Statement 1 is correct.
Anti-radiation missiles lock onto electromagnetic emissions produced by ground-based enemy radars.
2
Evaluate Statement 2 regarding the propulsion mechanism of Rudram-1.
Rudram-1 is propelled by a dual-pulse solid rocket motor, providing variable thrust during different flight phases rather than using a liquid-fuel ramjet. Thus, Statement 2 is incorrect.
Confusing solid-propellant rocket motors with liquid ramjet engines is a standard distractor in defense technology assessments.
3
Evaluate Statement 3 regarding launch platform integration and guidance systems.
Rudram-1 is integrated into the Indian Air Force's Su-30MKI fighter aircraft and employs a Passive Homing Head (PHH) system to track emissions across a broad band of frequencies. Thus, Statement 3 is correct.
Passive homing head sensors allow the missile to detect and track target signals without revealing its own presence.
