INTRODUCTION

They uses the technology i.e VLO “VERY LOW OBSRVABLE TECHNOLOGY..”

Fighter planes are made so they are harder to be detected by the radar and other devices

They uses the technologies that reduce reflection/emission of radar, infrared,visible light, radio-frequency (RF) spectrum, and audio, known as stealth technology.

Saving military budget.

Develop the military secretes

Stealth aircraft are invisible to radar

SUMMARY•Stealth technology referred as “VLO” ie “VERY LOW OBSERVABLE TECHNOLOGY”

•first true "stealth" aircraft may have been the Horten Ho 229 flying wing

•The goal of stealth technology is to make an airplane invisible to radar

•RAM reffers to “RADAR ABSORBENT MATERIALS” .RAM Reffers to “RADAR ABSORBENT MATERIALS” . •Active cancellation is a theoretical military jamming system• •Plasma stealth is a proposed process that uses ionized gas (plasma) to reduce the radar cross se ction (RCS) of an aircraft.

•to degrading the performance of IRST systems is to ensure that the exhaust dissipates as quickly as possible after leaving the aircraft.

•Over-the-horizon radar is a design concept that increases radar's effective range over conventional radar
