What is Ballistic Missiles?
Historical Background
Key Points
12 points- 1.
Ballistic missiles are primarily used for delivering nuclear, chemical, or conventional explosives over long distances.
- 2.
They consist of several stages, each with its own engine and fuel, which are jettisoned as the missile ascends to increase efficiency.
- 3.
Guidance systems use inertial navigation, GPS, or star tracking to maintain accuracy during flight.
- 4.
The range of a ballistic missile is determined by the amount of propellant it carries and the efficiency of its engines.
- 5.
Ballistic missiles are different from cruise missiles, which are powered throughout their flight and fly within the atmosphere.

Ballistic missiles are important for GS-3 (Science and Technology, Security) and Essay papers. Questions can focus on India's missile program, the implications of missile proliferation, or the role of ballistic missiles in international relations. In Prelims, factual questions about missile ranges and technologies are common.
In Mains, expect analytical questions about the strategic implications of missile development and the effectiveness of arms control regimes. Recent years have seen questions on India's defense capabilities and the impact of emerging technologies on national security. To answer effectively, understand the different types of missiles, their capabilities, and the geopolitical context of their development and deployment.
Frequently Asked Questions
61. What are ballistic missiles, and how are they categorized based on range?
Ballistic missiles are rocket-propelled weapons that follow a ballistic trajectory to deliver a payload to a target. They are guided during the initial phase but then follow a free-falling trajectory. Based on range, they are categorized as: * Short-range (less than 1,000 km) * Medium-range (1,000-3,000 km) * Intermediate-range (3,000-5,500 km) * Intercontinental (over 5,500 km)
- •Short-range: Less than 1,000 km
- •Medium-range: 1,000-3,000 km
- •Intermediate-range: 3,000-5,500 km
- •Intercontinental: Over 5,500 km
Exam Tip
Remember the range classifications for prelims. For mains, you can use this classification to discuss the strategic implications of different missile types.
