Development of Camouflage
<a href='http://someinterestingfacts.net/how-stealth-technology-works/' ><br>
Early form of camouflage </a>was developed during Boer War for soldiers to remain unseen using variety of materials, colorings and styles to blend into various terrains -
Visibility Reduction in WWI
Visibility was the sole concern in World War I. Hence, German designers produced a largely transparent monoplane; a transparent material derived from cellulose, the basis of movie film, covered its wings and fuselage. Interior struts and other parts were painted with light colors to further reduce visibility. -
Transparent Aircraft
Soviet aircraft designers attempted to design transparent aircraft. -
Invention of RADAR
RADAR (Radio Detection And Ranging) was invented to detect distant objects, mostly aircraft and ships. -
Diffused Lighting Camouflage
Royal Canadian navy tested on diffused lighting camouflage. -
U-480 - First Stealth Submarine
First stealth submarine, U-480, built by the Germans was launched during the World War II.
Anechoic tile rubber coating (absorb sound waves of active sonar to reduce or distort the return signal, hence, reducing its effective range) was featured to defeat ASDIC (active sound detection project) sonar.
Radar absorbent rubber/semiconductor composite paints were used -
Horten Ho 229
Horten Ho 229 flying wing is one of the earliest stealth aircraft designed by Germans late in World War II. It absorbs electromagnetic waves (radar) and has a small radar cross-section -
ADAR-absorbent paint
Americans and the British followed up with diffused lighting camouflage with the Grumman Avenger with Yehudi lights. However later on that year, RADAR-absorbent paint containing iron was developed by the U.S. -
Avro Vulcan - British Bomber
Avro Vulcan, a British Bomber had a remarkably small appearance on radar despite its large size, and occasionally disappeared from radar screens entirely -
A-12, Blackbird
A-12, the first top-secret Blackbird series that operated at high altitude and speed to avoid radar detection was produced -
SR-71
SR-71 was developed and surpassed prior Blackbird models in both altitude and speed that included stealthy features such as its canted vertical stabilizers, the use of composite materials in key locations, and the overall finish in radar absorbing paint. -
The Have Blue Program
Stealth technology demonstrator, The Have Blue program preceded the F-117 Nighthawk production stealth aircraft. -
F-117 Nighthawk first flight
First flight of the F-117 Nighthawk which is a stealth ground-attack aircraft -
Large-scale use of F-117
First large-scale use of the F-117 during the Gulf War -
Cruise Missiles
U.S. cruise missiles stealth technology carries either nuclear or conventional warheads deployed during Gulf War and in Afghanistan
