Stealth technology reduces the radar cross section of aircraft, making them harder to detect.
Flat angled surfaces on stealth aircraft deflect radar waves in different directions.
Radar absorbent materials like iron ball paint absorb radar waves and convert them into heat energy.
Top-mounted jet engines and non-circular exhaust pipes help reduce the heat signature of stealth aircraft.
Stealth aircraft are often painted black or gray to reduce their visibility in different lighting conditions.
