Like something right out of Star Trek. In fact whichever stoopid StarTrek movie it was where they come back in time to save the whales they talk about transparent aluminum. Well....transparent aluminum becomes reality. And its bullet proof to boot. B) Amazing.

Air Force testing new transparent armor

10/17/2005 - WRIGHT-PATTERSON AIR FORCE BASE, Ohio (AFPN) -- Engineers here are testing a new kind of transparent armor -- stronger and lighter than traditional materials -- that could stop armor-piercing weapons from penetrating vehicle windows.

The Air Force Research Laboratory's materials and manufacturing directorate is testing aluminum oxynitride -- ALONtm -- as a replacement for the traditional multi-layered glass transparencies now used in existing ground and air armored vehicles.

The test is being done in conjunction with the Army Research Laboratory at Aberdeen Proving Grounds, Md., and University of Dayton Research Institute, Ohio.

ALONtm is a ceramic compound with a high compressive strength and durability. When polished, it is the premier transparent armor for use in armored vehicles, said. 1st Lt. Joseph La Monica, transparent armor sub-direction lead

"The substance itself is light years ahead of glass," he said, adding that it offers "higher performance and lighter weight."

Traditional transparent armor is thick layers of bonded glass. The new armor combines the transparent ALONtm piece as a strike plate, a middle section of glass and a polymer backing. Each layer is visibly thinner than the traditional layers.

ALONtm is virtually scratch resistant, offers substantial impact resistance, and provides better durability and protection against armor piercing threats, at roughly half the weight and half the thickness of traditional glass transparent armor, said the lieutenant.

In a June 2004demonstration, an ALONtm test pieces held up to both a .30 caliber Russian M-44 sniper rifle and a .50 caliber Browning Sniper Rifle with armor piercing bullets. While the bullets pierced the glass samples, the armor withstood the impact with no penetration.  <a href='http://www.af.mil/news/story.asp?id=123012131' target='_blank'><span style='color:orange'>READMORE...</span></a>

Sounds cool.

Just read the full article...they make a good point that it's more expensive than glass, but will save money in the end since it won't need to be replaced.
