Battleship would be invisible to the eye, radar, produce no heat signature and make no sound

The ultimate in camouflage for military purposes would be complete invisibility. Invisibility has been a major factor in fiction going back to ancient Greek mythologies to contemporary science fiction. While we are far away from space ships capable of intergalactic travel like Stargate Atlantis, a clocking device may be closer than you think.

Metamaterials refract light at a negative angle, rather than refracting light like normal materials that can be seen. The properties of metamaterials allow scientists to bend light around objects making them invisible to the naked eye. DailyTech reported on similar technology before when researchers at the University of Maryland were able to cloak a small 10 micrometer circle making it invisible to the eye.

While 10 micrometers is incredibly small, the scientists hope to one day scale the size of the cloak to hide people and objects. This is exactly what researchers at the Britannia Royal Navy College hope to do, but on a much grander scale. The scientist are developing a method to render full battleships invisible to not only the naked eye, but to radar as well. The researchers also hope to mask the sound produced by the ships as well as its heat signature.

If the scientists are able to accomplish the goal, it would mean the British Navy would have battleships invisible to the naked eye, radar, heat-seeking missiles and that produce no noise. If successful, the only indication that the ship is coming would be the water displaced by the ship.

According to several amateur satellite watchers the US already has several "stealth" sats that are very hard to near impossible to pick up using regular optics.

I'd actually read about that type of spy satellite, that technology is more suited to relatively low cross section craft.

I was thinking more along the lines of military communications satellites which need to have large surface area antenna pointed earthward with an unobstructed view. I do have to wonder just what wavelengths this cloak technology works over. If your cloak is opaque to radio, optical and microwave then it's kind of tricky to recieve communications inside not to mention that you can't see out! Also it is worth wondering whether this technology is symmetrical, i.e. can you transmit out of the cloak?

I would imagine that you could keep your antennas uncloaked (by just not making it out of metametal or whatever the stuff is), as it's unlikely they will give much of a signal or be visible at any practical range. By the time they could be seen, you'd be running over the observer.
