==Description==

The [[concept]] of stealth is to operate or hide without giving [[enemy]] forces any indications as to the [[presence]] of friendly forces. This concept was first [[explored]] through [[camouflage]] by blending into the background visual clutter. As the potency of detection and interception technologies ([[radar]], IRST, surface-to-air missiles etc.) have increased over time, so too has the extent to which the [[design]] and operation of military personnel and vehicles have been affected in [[response]]. Some military uniforms are treated with [[chemicals]] to reduce their [http://en.wikipedia.org/wiki/Infrared infrared] signature. A [[modern]] "stealth" vehicle will generally have been designed from the outset to have reduced or controlled signature. Varying degrees of stealth can be [[achieved]]. The exact level and [[nature]] of stealth embodied in a particular [[design]] is determined by the [[prediction]] of likely threat capabilities.

Designers turned to develop a particular shape for planes that tended to reduce detection, by redirecting [[electromagnetic]] [[waves]] from radars.
