$400,000 a bone dome
Yes but it's a
special bone dome. Cost is now irreverent to this program because they've got them by the short and curlys...
Keep in mind that the bone dome replaces a color holographic HUD in the F-35. I don't know what the price of the HUD and fancy helmet are in a Typhoon, F-16, F-18, etc, but I would not be surprised if together they come close to or are maybe even more expensive than the F-35 bone dome.
