Examples: F-35 of USA, J-20 of China, Su-57 of Russia, and AMCA of India, which is under development.

Stealth Technology

Radar Cross-Section (RCS): Measure of how detectable an object is by radar; stealth aircraft have very small RCS.
Radar Absorbing Material (RAM): Special coating or material used to absorb radar waves and reduce radar reflection.
Internal weapon carriage: Weapons are kept inside the aircraft body to avoid radar reflection from external payloads.
Reduced infrared signature: Engine heat and noise are reduced to avoid infrared detection.
Stealth aircraft can still be detected by certain radar frequencies and advanced tracking systems.
Metamaterials help reduce electromagnetic scattering, improving stealth characteristics.

Indigenous Defence Hardware

Su-30 MKI fighter jets and T-90 tanks are manufactured in India under licensed production.
Akula-class submarine is Russian-origin and not manufactured in India.
Important indigenous or India-manufactured systems include Tejas LCA, Arjun MBT, Akash Missile System, Pinaka Rocket System, and AMCA.
