The US Air Force has released the draft Key Performance Parameters for the T-X jet trainer it hopes will eventually replace the Northrop T-38C Talon. From the specifications, the USAF is asking for a pretty robust set of capabilities. One of the requirements is that it should be able to take the place of the F-22 bridge course (Eight rides in a two-seat F-16, doing night aerial refueling and making sure the new guys can pull 9Gs while operating the radar and what not) before new pilots head to the Raptor B-course. Lockheed Martin, BAE Systems, Alenia Aermacchi and Boeing are expected to bid.
