A super-powerful gun that shoots rounds more than 160km away – at several times the speed of sound – is being developed for US Navy warships.

The weapon is known as an electromagnetic railgun. It consists of parallel rails and uses a magnetic field and electric current, instead of chemicals, to generate energy to fire the rounds, wh.

The Navy says an industry-built prototype of the gun is being tested at the Naval Surface Warfare Center Dahlgren Division in northern Virginia.

At this stage, they’re focused on measuring the gun’s barrel life and structural integrity because it is capable of firing rounds at up to 9000kmh, or more than seven times the speed of sound. More research and development is needed to over the next five years to ensure the weapon can cool down and handle repetitive fire. The Navy wants to be able to fire 10 rounds a minute.

They’re also working to ensure that the roughly 18kg metal projectile the gun will ultimately fire can withstand the heat and G-forces from the launch and will not disintegrate. And they need to make sure any electronics in the projectile, such as a GPS system, are safe.

Navy researchers said the weapon’s high-velocity and range would allow ships to provide support for Marines storming a beach. It could also target enemy ships and provide self-defense against cruise and ballistic missiles.

Currently, 5-inch guns on destroyers have a range of about 23km.

“As you can see, it represents a significant increase in range,” Roger Ellis, the Office of Naval Research’s electromagnetic railgun program manager, said in a conference call with reporters.

Ellis said that because the gun can fire at such high speeds, it wouldn’t necessarily have to shoot an explosive to inflict damage, either. He would only say that it would carry a “lethal mechanism.”

The Navy has been developing the weapon since 2005 at a cost of about $US240 million. Similar funding is expected to keep the program going through 2017, when the Navy anticipates the weapon will be ready. It could still take several more years before the gun is put on ships.

The 12m-long gun being tested more closely mirrors a final product than previous versions. It has been test fired six times since last week.

A second industry-built prototype will be delivered to the Navy for testing in April.

General Atomics, one of the companies providing a prototype, has also invested $20 million.

“We believe this is definitely a game changing capability that’ll enable our forward presence and freedom of the seas,” said Tom Hurn, director of railgun programmes, for General Atomics, one of the two companies providing a prototype.

Now, let’s zoom in under the nose of this same ship:

COLD WAR my ass.
Believe nothing that you hear and only half of what you see.

My Proposed new phone – New details emerge on the Samsung Galaxy SIII | Daily Mobile

New details emerge on the Samsung Galaxy SIII

While the all world of Android fans wait for the official release of the Samsung Galaxy SIII, new details emerge based on rumors and leaks from, what so called, trusted sources. Today, BRG announced some interesting specs of this super-phone.

According to BRG’s sources, the new SGS3 will feature a hoping 4.8″ display that most likely will have a 720p HD resolution, even if they don’t have confirmation on this. The most interesting part is the choice of the materials for the back of the phone. SGS2 has been considered by the majority of the community as the best phone in terms of hardware but that didn’t saved him from several critics because of the use of plastic. BRG’s site is advancing that the new SGS3 will have a ceramic back which is an interesting choice by Samsung.

Other features expected are the Quad-Core processor, Ice Cream Sandwich out of the box, good quality cameras and 4G LTE, as already been advanced before by most of the sites.

We will have to wait a bit more to see the official announcement of this phone and, if you were waiting to get some news from the Mobile World Congress 2012, we’re sorry to let you know that Samsung already advanced that SGS3 will not be presented at Barcelona and will be released on a dedicated event to be host later.
