Detailed Solution for Test: Defence Technology - 2 - Question 1

The correct answer is Neither 1 nor 2

Missiles:

  • Ballistic missiles are powered by rocket engines throughout their entire trajectory. The engine operates for the first few minutes of flight, and then the missile follows a trajectory guided by gravity.
  • On the other hand, cruise missiles are jet-propelled and they maintain powered flight for the entirety of their journey, not just the initial phase. Hence statement 1 is incorrect
  • Agni-V is an Indian intercontinental ballistic missile (ICBM) that is capable of carrying nuclear warheads. It uses solid fuel and has a range of over 5,000 kilometers.
  • On the other hand, BrahMos is a supersonic cruise missile developed by India and Russia. It uses a two-stage propulsion system, with solid propellant in the first stage and liquid ramjet in the second stage. Hence statement 2 is incorrect
