US Army is developing 'invisibility suit' for soldiers

YEREVAN, MAY 11, ARMENPRESS: The US Army is developing an invisibility suits for its soldiers, Armenpress reports, citing the Daily Mail. It has requested firms developing 'stealth fabrics' to get in touch - and is hoping to test the first prototypes within 18 months.

It is hoped the suit will work in every terrain, from deserts to jungles - and in every temperature.

The US army's call for proposals from companies calls for wearable camouflage with a chameleon-like ability to change according to the background.

'A chameleon-like or adaptive camouflage system would continuously update the color and pattern, concealing the Soldier in the current environment.'

It calls for firms to 'Develop an innovative adaptive camouflage technology that can be used by individual soldiers in various land environments. A non-powered solution is preferred.'

Contractors will demonstrate the feasibility of their approach in the first six months of the programme.

Those selected for the following one-year phase will submit 10 prototype uniforms for testing.

These need to work in all terrain from all angles.

They also need to function across a wide range of temperatures, in rain and snow, and without hampering a soldier's normal duties.

If the adaptive camouflage requires a power source, this must weigh no more than 0.45 kilograms and provide at least 8 hours of operation.

It is believed two options are under consideration.

In 2006, John Pendry, a theoretical physicist at Imperial College London, showed that it should be possible to bend light around an object and hide it using metamaterials – which channel electromagnetic waves.

However, many only work in the lab with specific wavelengths or from certain angles.

Work with TV-like LEDs was hampered by power and computing requirements.

But although they can bend light, metamaterials cannot make things disappear completely.

Despite this, some firms claim they already have working products.

Guy Cramer, CEO of Canadian camouflage makers Hyperstealth Biotechnology, says he demonstrated metamaterial camouflage to US military scientists last year, and that the new project will allow him to move forward with it.

But Cramer won't yet reveal details or release photographs of the material.

'What's the holdup on our Quantum Stealth (Light Bending material)?' the firm wrote.

'The U.S. military needed to put in place the requirement, without that requirement we were not allowed to work with them.

'Key people in the U.S. Military had assumed bending light across the Ultraviolet, Visible and Infrared spectrum was impossible until Hyperstealth recently demonstrated that and more to those people.

'This requirement for light weight, passive (non-powered) adaptive camouflage has now been issued.'
