    Which of the following statements best depict the concept of Ballistic Missiles:

    A)  These are the Missiles created to carry nuclear warheads.

    B)  These are the missiles which follow a suborbital path in one of their stages.

    C)  These are the missiles which travel at supersonic speeds.

    D)  These are the Missiles which have inter-continental attack capability.

    Correct Answer: B

    Solution :

    [b] A ballistic missile is a missile (rocket) that follows a ballistic flight path with the objective of delivering one or more warheads to a predetermined target. A ballistic missile is only guided during the relatively brief initial powered phase of flight, whose trajectory is subsequently governed by the laws of classical mechanics, in contrast (for example) to a cruise missile which is aerodynamically guided in powered flight. Shorter range ballistic missiles stay within the Earth's atmosphere, while longer range ones are designed to spend some of their flight time above the atmosphere and are thus considered sub-orbital,
