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.

Negatives in context

It appears that a lot of the negatives being brought up have very little impact.

The ease of spotting most warships is the solid colour against the water, therefore even if the ship wasn't perfectly cloaked the distortion effect of the camoflauge would help it blend in with the surrounding water. Jungle camoflauge doesn't look like jungle but it does offer a good amount of protection against detection.

There'll be the wake to give the ship away, yes that is a possibility but whats harder to aim at, a moving bit of water or a fully viewable cruiser?

Now the most important aspect is range, a standard fit light cannon for the US navy has a range of 13miles (24Km). Are you going to notice wake at that distance or even that the invisibility isn't perfect? The invisible craft has spotted the enemy well before its been spotted and can close in at a slower speed to reduce wake and get the first shot in at well below the maximum range for greater efficiency. It doesn't matter if the invisibility stops working at five miles when you've started to rip it to shreds from seven miles away.

er... did you actually read my post?
