If that's a current video, then #6 went retro. We haven't used anything other than the HGU-55 or HGU-55CE in the viper for at least 10 years. I never paid much attention to the Thunderbirds when I was active duty, but maybe they utilize older equipment. I would find that hard to believe, though, given the AF's unyielding attention to equipment regs and T.O.'s. Does anyone know for certain? Do any of you out there work life support at Nellis??
