Consider the following statements: 1. Ballistic missiles are jet-propelled at subsonic speeds throughout their flights, while cruise missiles are rocket-powered only in the initial phase of flight. 2. Agni-V is a medium-range supersonic cruise missile, while BrahMos is a solid-fuelled intercontinental ballistic missile. Which of the statements given above is/are correct?

  1. 1 only
  2. 2 only
  3. Both 1 and 2
  4. Neither 1 nor 2

Answer

Neither 1 nor 2

Statement 1: Incorrect. This is reversed: ballistic missiles are typically rocket-propelled in the initial phase and then follow a ballistic trajectory, while cruise missiles are jet/air-breathing powered for most of their flight and can fly at subsonic or supersonic speeds.

Statement 2: Incorrect. Agni-V is a long-range/intercontinental-class ballistic missile, not a medium-range cruise missile; BrahMos is a supersonic cruise missile, not a solid-fuelled intercontinental ballistic missile.

Therefore, neither 1 nor 2 is correct.
