Ballistic Missile vs Cruise Missile Difference, MIRV Technology Explained for Science and Technology

Описание: In this Science and Technology session for UPSC, we clearly understand the difference between Ballistic Missile and Cruise Missile, a topic frequently asked in UPSC Prelims and Mains under Defence Technology and Security.

This video explains how ballistic missiles follow a rocket engine based trajectory, travel outside the atmosphere, and include boost phase, midcourse phase, and terminal phase. We also discuss why they require both fuel and oxidizer and how MIRV technology works. In contrast, cruise missiles operate within the atmosphere, use jet engine propulsion, maintain continuous guidance, and offer higher precision.

Examples like Prithvi, Agni and BrahMos are discussed to help you connect static concepts with current affairs. This session is extremely useful for Science and Technology preparation, especially for non science background aspirants preparing for UPSC.

Perfect for UPSC Prelims, Mains GS 3, Defence Technology and Internal Security preparation.
