Red Flag was to game China and Russia simultaneously. The Gentleman argues for capacity, the F-15C to F-15X with upgraded EOTS, Electro-Optics, ADAS etc. would supply that capacity...

which presumably is the cause of the USAF's hard and fast deadline on the survey of OLED companies (company) that would enable that cross service upgrade. However Congress got a report slamming that plan advising against in favor of the F-35. So we can have a Lockheed-Boeing shootout at the Lobbyist Corral.
Sad to say Derrick nobody is talking GG3 as a viable alternative for the proposed system. (something crazy about the F-35 is that they change software depending on threats and circumstance, download daily if they have too. Ender's Game is right around the corner.)
