The Air Force makes it clear in the just-released tanker replacement RFI that any potential candidate should not only handle aerial refueling but also secondary missions, such as cargo and passenger hauling, aeromedical evacuation, and command, control, communications, and computer augmentation. (The latter capability was advocated by former Chief of Staff Gen. John Jumper, who wanted to use tankers loitering over a combat area to provide an additional comm node.)
The Air Force has tapped sites in Oregon to build its first two new Over-the-Horizon Radars, capable of detecting inbound missile threats from up to 4,000 nautical miles away. The service is hoping to start construction by the end of 2028.
