The geometry of the surfaces (to change the reflection), the materials of the surfaces (to absorb radar), the exhaust is cooled to reduce heat signature, anything that reduces the heat and radar signature of the platform
yes there is
The F-22 stealth raptor is the stealth combat aircraft.
titanium
All stealth aircraft are built with the intent of being 'invisible' to radar. One of the best was the F-117.
Stealth remained the weapon enroute to target.
The T-50.
Fast enough to do the job. The actual maximum speed of all stealth aircraft is classified. Like any aircraft, the speed will depend on many factors.
like a normal aircraft
Stealth aircraft are made so they don't show up on radar very well, or at all. This is important if you're going out to blow something up and don't want to be seen. Commercial aircraft could not be stealth aircraft because you really need to be able to see one on radar. Air Traffic Control uses radar to detect aircraft in its area, other planes use radar to detect you in the sky...having a commercial plane that couldn't be seen on radar would be very bad. - - - - - the difference is like police and thief.
semi stealth means that the aircraft is hard to detect on enemy radar systems giving the aircraft the upper hand in a dogfight. the F-22 is a prime example of this.
A stealth air craft can be destroyed like any other airplane. The name stealth aircraft comes from how these airplanes are "invisible" to radar systems. P.S. Aircraft is already plural. Saying aircrafts is like say chineses
Satellites can detect stealth aircraft, but their effectiveness depends on various factors, including the aircraft's design and the satellite's sensor capabilities. Stealth technology reduces an aircraft's radar cross-section, making it less visible to traditional radar systems. However, satellites equipped with advanced sensors, such as infrared or synthetic aperture radar, may still detect the heat signature or other emissions from stealth aircraft. Ultimately, while challenging, detection is possible under certain conditions.
