Again, the HUD has been in service since the end of the second world war, especially in aircraft. How the hell would you be able to tell where your missile has locked onto otherwise?
And the HMDS (Helmet-Mounted Display System) is only different in the F-35 as it's on the helmet itself. Just easier so you can see your HUD when you turn your head. Not much different.
What seabeast talks about is either halo-style helmets with a HUD linked up to your gun and your suit, or something that one of the faggot admirals said one day and ended with "Would that be cool?".
@2310: Quit talking about shit you don't know about. Please.
