This is the pilot helmet included with the upcoming F-35 stealth fighter being jointly developed by the United States and the United Kingdom. The helmet pictured is apparently capable of giving the pilot vision through the aircraft fuselage as well as interfacing with the HUD. The F-35 is slated for release in 2011.
