A years-in-the-making, top-secret engineering and design project for a superaerodynamic suit to be worn by U.S. speedskaters at next month's Winter Olympics was finally unveiled Thursday.
Defense contractor Lockheed Martin and sporting goods company Under Armour released photos of the suit they're calling "Mach 39." It has been kept so tightly under wraps that the sport's governing body wouldn't even allow it to be worn at the Olympic trials in Salt Lake City.
What's so revolutionary about the uniform?
