Defence Technology refers to advanced scientific innovations and equipment used by military forces for national security. In SSC CGL, this topic covers modern weapons, defence systems, and strategic technologies used by Indian Armed Forces. Core Defence Technologies include missile systems, radar technology, aircraft, naval vessels, and cyber warfare tools. India has developed indigenous defence capabilities through organizations like DRDO (Defence Research and Development Organisation), HAL (Hindustan Aeronautics Limited), and ISRO for military satellites.
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.
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).
Recall BrahMos stands for Brahmaputra (India) + Moscow (Russia)
It's a joint venture between India and Russia
Developed by BrahMos Aerospace Limited
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.
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.
