What characteristics must a airplane have in order not to be visible on enemy's radar screen?
The most common stealth characteristics include low radar and infrared signatures, reduced acoustic and visual signatures, and advanced materials and design techniques.
Radar signature reduction, also known as radar stealth, involves designing aircraft or objects with features that minimize their reflection of radar waves, making them harder to detect by radar systems.
Stealth aircraft reduce their infrared signature through the use of heat-absorbing materials, engine exhaust cooling systems, and infrared-absorbing coatings.
Acoustic signature reduction is the process of minimizing the noise produced by an aircraft or object, making it harder to detect by acoustic sensors.
The advantages of having stealth characteristics include improved survivability, increased mission success rates, and enhanced operational flexibility in high-threat environments.
