The main aim is to create a lightweight and comfortable, high tech battle suit for the modern soldier using the nanomaterials.

Too create a bulletproof, resistant jumpsuit, no thicker than ordinary spandex, that monitors health, eases injuries, communicates automatically, and reacts instantly to chemical and biological agents.

Researchers were able to create ultra hydrophobic surfaces( water proof) using a technique called Chemical Vapour Deposition(CVD).

With CVD they could deposit nanolayers of Teflon on kevlar panels the material used to make bullet proof vests.

Sea snails and abalone are guiding scientists in their search for strong and lightweight armor. Sea Shells and AbaloneAbalone shells are strong and lightweight. They can repair themselves, too.

NANOTECHNOLOGY is taking a cue from nature in developing materials to protect the modern soldier. SCIENTISTS were able to examine the nanostructure of the scales of the Senegal bichir or the dinosaur eel, a species that has been able to survive enemy attacks for over 96 million years.The four layers of the scales dissipate the energy of a strike, protect the soft tissue beneath the scales, and also prevent the spread of fractures within the scale.

Another new nano-armor is called "smart" body armor. It weaves thin pads or cloth from fibers that can sense the impact of a bullet or shrapnel and automatically stiffen. This material would be even more resistant to penetration and less cumbersome than the ceramic-plate armor troops wear now.Concerns about biochemical-warfare have resulted in exploration into nano-size umbrellas that open to seal the cloth's pores, making it impervious to airborne chemicals and pathogens. That would be much easier and lighter than the current equipment required.

How could you become invisible? Here are a couple of nano-ways:

Scientists are manipulating light so soldiers seem to disappear.

Scientists are also working on "electrochromic camouflage" fabric which changes colors instantly to blend in with the surroundings.

Artificial muscles that could enable soldiers to leap tall walls, if not buildings, are in the works, too. One type uses nanotechnology and electricity. It flexes when jolted by electricity, then relaxes when the electricity is turned off. So far, though, its reactions are much too slow

In addition, sensors would provide the soldier's vital signs and location to medics via radio. Until the new nano-sensored garment is ready, soldiers will wear an adhesive chest patch fitted with sensors and a tiny radio.If a soldier is injured in the arm or leg, thanks to nano-fibers in the uniform, the fabric would constrict into a tourniquet. This will be a real life-saver, because half of all battlefield deaths are due to massive blood loss before wounded soldiers can be treated.

Future fighters and missiles are expected to be lightweight, intelli- gence guided, low in signature, high speed and manoeuvrable. The onboard intelligence will continuously increase, facilitating auto- mated control and maintenance. Special attention goes to specific detection and surveillance sensors and weapon systems.

Nanotechnology and microsystems enable miniaturised components and very small satellites having significant lower weight and size than present satellites. This will make them cheaper to manufacture and to lift them into space orbit. Ideally one could launch into orbit a number of redundant micro satellites which can be wirelessly connected to each other..With a distributed network of small satellites instead of one big one, both functionality as well as redundancy is gained. Each micro satellite has his own power source/solar panels, dedicated sensor system, micro modular propulsion / thruster system, and navigation sensors. It can be expected, that the trend towards smaller satellites will continue in the coming years

Next-generation would have all-electric warship thanks to nanotechnology. This new technology will control the ship and lead to major improvements in effectiveness, survivability and cost savings. The space needed for energy production on warships will be reduced significantly. This will free onboard space so that it can be used for other functions
