    How does a stealth aircraft work?

    A:

    Stealth aircraft use a combination of physical construction, radar-absorbing materials and electromagnetic emission controls to reduce their presence on enemy radar screens. Radar relies on the reflection of a radio wave, and stealth planes are built with jagged angles to reduce clean reflections returning to the scanner. The materials in the planes' skin also dampen radar signals, and their own electronic emissions are kept low to avoid detection.
