Has Star Trek’s “transparent aluminum” become real? Sort of:
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 stuff is expensive, but worth it. Check out the whole thing for all the tech details.
