Core Concept

Read this first — the foundation of the topic

→Missile Classification follows range-based categories

Short Range (up to 1000 km), Medium Range (1000-3000 km), Intermediate Range (3000-5500 km), and Intercontinental (above 5500 km). Indian missiles like Agni series, Prithvi, and BrahMos fall into different categories. Radar Technology uses radio waves to detect objects. It works on the principle of reflection - radio waves bounce back from targets. Modern radars can track multiple targets simultaneously and provide early warning systems. Exam Pattern Analysis shows SSC CGL frequently asks about Indian missile names, their ranges, and defence organizations.

Questions often test knowledge of recent defence deals, indigenous projects, and military ranks across services

⚡Memory Trick for Indian Missiles

'All Pilots Bring Ammunition Safely' - Agni (long-range), Prithvi (surface-to-surface), BrahMos (cruise missile), Akash (surface-to-air), Shaurya (tactical).

Worked Example

Solve this step-by-step before moving on

1

Step 1

Recall BrahMos stands for Brahmaputra (India) + Moscow (Russia)

2

Step 2

It's a joint venture between India and Russia

3

Step 3

Developed by BrahMos Aerospace Limited

4

Step 4

Answer - India and Russia Another Shortcut: Remember defence organization headquarters - DRDO (New Delhi), HAL (Bangalore), ISRO (Bangalore), OFB (Kolkata). Most questions ask location of these organizations. Stealth Technology makes aircraft invisible to radar by using special materials and design shapes. Indian examples include development of Advanced Medium Combat Aircraft (AMCA) with stealth capabilities. Cyber Warfare has become crucial in modern defence. India established Defence Cyber Agency in 2019 to protect military networks from cyber attacks. Common Mistake: Students confuse missile ranges and mix up indigenous vs imported defence equipment. Always remember that Agni series has longest range among Indian missiles, while BrahMos is fastest supersonic cruise missile.

🔑 Key Points

DRDO is India's premier defence research organization established in 1958
BrahMos is world's fastest supersonic cruise missile with 290 km range
Agni-5 is India's longest range missile capable of hitting 5000+ km targets
INS Vikrant is India's first indigenously built aircraft carrier
Tejas is India's indigenous Light Combat Aircraft developed by HAL
ASAT (Anti-Satellite) test made India 4th country with space warfare capability
Defence Cyber Agency was established in 2019 for cyber security
Make in India initiative aims for 70% indigenous defence production by 2025

📌 Exam Facts

DRDO was established on 1st January 1958
BrahMos missile travels at speed of Mach 2.8 (nearly 3 times speed of sound)
India conducted ASAT test 'Mission Shakti' on 27th March 2019
Agni-5 missile has range of 5000-8000 kilometers
INS Vikrant was commissioned on 2nd September 2022
Tejas aircraft received Final Operational Clearance in 2019
Defence Cyber Agency headquarters is located in New Delhi
India's defence budget for 2023-24 is Rs 5.94 lakh crores

🚀 60-Second Revision

Remember: DRDO established 1958, headquarters New Delhi
Formula: BrahMos range 290 km, speed Mach 2.8
Trap: Don't confuse Agni-5 (longest range) with BrahMos (fastest speed)
Key Fact: Mission Shakti made India 4th space power in 2019
Remember: Tejas by HAL, INS Vikrant commissioned 2022
Important: Defence Cyber Agency formed 2019 for cyber security
Target: Make in India aims 70% indigenous defence production by 2025
