Self-steering bullet researched by US weapons experts

A self-guiding bullet that can steer itself towards its target is being developed for use by the US military.

The bullet uses tiny fins to correct the course of its flight allowing it to hit laser-illuminated targets.

It is designed to be capable of hitting objects at distances of about 2km (1.24 miles). Work on a prototype suggests that accuracy is best at longer ranges.

A think tank says the tech is well-suited to snipers, but worries about it being marketed to the public.

Work on the project is being carried out by an Albuquerque-based subsidiary of defence contractor Lockheed Martin on behalf of the US government.

The current prototype involves a 4in (10cm) bullet which includes an optical sensor in its nose to detect the laser. This information is then processed and used to move motors within the bullet which steer tiny fins, altering the ammunition's path.

"We can make corrections 30 times per second," said researcher Red Jones.

"That means we can over-correct, so we don't have to be as precise each time."

Accuracy
The team has carried out both field tests and computer simulations, and says "engineering issues" remain. However, they add that they are confident of bringing the product to market.

Experts say there would be great demand for the innovation on the battlefield.

"One of the big successes in Libya was that the accuracy of the munitions used was much higher than in previous campaigns," Elizabeth Quintana, senior research fellow at the Royal United Services Institute think tank told the BBC.

"97% of Nato's weapons hit their target to within about 2m (6.5ft). But that was achieved through air munitions.

"This would be a revolution for ground forces, and may help further cut down on civilian casualties in future conflicts."

Unlike most bullets the self-guided prototype minimises spin, aiming to fly like a dart.


Researchers say special gunpowder may be needed to help the bullet achieve faster speeds
Normally small calibre rifle bullets are spun at over 2,000 revolutions per second to stabilise their flightpath and maximise speed.

But the team's patent application notes that previous attempts to create self-guiding rapidly-spinning bullets ran into the problem that the electronics required became too complicated.

To simplify things the researchers moved the bullet's centre of gravity further forward than it would normally be.

When combined with the fins this caused it to only spin a few revolutions per second, making it easier to steer. Because the bullet's motion settles the longer it is in flight, the researchers say its accuracy improves at longer ranges.

Tests with commercially available gunpowder have measured the bullet reaching just over twice the speed of sound (2,400ft per second), which is still below standard military speeds.

But the researchers say they are confident that they can increase its velocity with customised gunpowder.

Terrorism
A press release said that: "Potential customers include the military, law enforcement and recreational shooters."

That concerns some industry watchers.

"The public may be uncomfortable with the implications of people being able to use this without needing to have a sight line to the target - you could see this having terrorist uses," said Ms Quintana.

"There's talk of selling to recreational hunters, but I would imagine the authorities would want to limit the public's access to this kind of technology.

"But it would be useful for law enforcement - particularly in hostage situations."

i hope the research fails and the researchers die of diohrea.....

yes u.s has made a flying carpet also but it's only used for transport of these bullets

US has a flying carpet bomber already, right?

no no not bomber, carpet like in Aladdin JK

Yes, I know, but I had a great picture to post here, but an Oxymoronic Name is just itching to hand out more infractions to me, so I cannot.

BTW, the carpet bomber is a real entity ( again I will not post a photo for fear of inviting wrath from Oxymoronic Name! )

Whenever I hear of "smart" machines, it reminds me of the elevators in the Hitchhiker's Guide.

“Not unnaturally, many elevators imbued with intelligence and precognition became terribly frustrated with the mindless business of going up and down, up and down, experimented briefly with the notion of going sideways, as a sort of existential protest, demanded participation in the decision-making process and finally took to squatting in basements sulking.

An impoverished hitch-hiker visiting any planets in the Sirius star system these days can pick up easy money working as a counsellor for neurotic elevators.”

^^^There are elevators designed for the next generation of skyscrapers that do go sideways as well as up and down.

Reality lags fiction, but not by much quite often.

apples and oranges.....

clean water saves lives....bullets end lives...
thats why i hope those researchers die and taste their own medivine as they are sat there creating a tool thay can only be usrd for death in third world....muslim.....countries....nothing else...

Big deal; the taliban have been using self steering bombs for decades.

Wouldn't it be easier to make the laser illuminator more powerful and simply use the laser as a weapon?

Where will you get the energy for tat? Keep popping in batterys every 10 seconds?
