GS PrelimsSecurityDefence Technology2023 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?
Correct Answer: Option D
Explanation
1. Statement 1: This statement incorrectly describes both types of missiles. Ballistic missiles are typically rocket-powered during the initial boost phase, after which they follow an unpowered, ballistic trajectory determined by gravity and atmospheric drag. Cruise missiles, on the other hand, are usually jet-propelled (using air-breathing engines) and fly at subsonic or supersonic speeds within the atmosphere throughout their flights, much like an aircraft. Therefore, Statement 1 is incorrect.
2. Statement 2: This statement mischaracterizes both missiles. Agni-V is an intercontinental ballistic missile (ICBM) with a range exceeding 5,000 km, powered by solid fuel stages; it is not a medium-range supersonic cruise missile. BrahMos is a supersonic cruise missile developed jointly by India and Russia; it is not an intercontinental ballistic missile. Therefore, Statement 2 is incorrect.
3. Since both statements are incorrect, the correct option is (D) Neither 1 nor 2.
