Prelims 2023 · Q58 · Missiles & defence systems

Consider the following statements :

  1. 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. 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?

Show answer

Answer: D. Statement 1 is wrong: it is reversed. Ballistic missiles are rocket-powered only in the initial phase and then follow a free-falling path, while cruise missiles are jet-powered throughout flight. Statement 2 is wrong: Agni-V is a long-range (about 5,000 km) ballistic missile, while BrahMos is a supersonic cruise missile. So neither.

Watch for: Both statements swap correct descriptions between two items.

Why the other options are wrong
  • A. Wrong because the ballistic and cruise descriptions are reversed.
  • B. Wrong because Agni-V and BrahMos are swapped.
  • C. Wrong because both statements are false.
