Wow...Self-steering bullet, and Drone will make those costly fighter

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.
Prototype bullet 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."

What are on Science fiction turn to reality!!! Will it Americans use
these newly invented weapons against uncle Assad and Uncle Mahmoud in
the even of wars?

You gonna see it this coming spring if Iran government does not back
down on their Nuclear bomb ambitions. Americans are developing a
modern bomb that will penetrate deep that can destroy the underground
nuclear facility in Iran. CBS just broadcasted it tonight. Israel is
going to attack Iran's underground nuclear facilities if Iran does not
back down, Israel is just waiting for the American bombs. I think it
will be interesting to see how Iran is responding to Israel's actions.

It's interesting that they can fit the guidance system into a bullet
head. Years ago during cold war, when I worked as part of the team of
missile guidance system, the tracking algorithm that estimate the
trajectory. The navigation system used the estimate and corrected the
path to target. It was small electronic system then, but it is big
enough to equal to the size of a small PC notebook of today. The longer
the flight path, the more accurate it was, but more susceptible to
counter measure (the pro and con). Technology is always progressing at a
very fast pace, but the fundamental knowledge that requires to do the
job always remain the same.
