General Dynamics was tied in with Alenia to offer the T-100 based on the M-346, but they pulled out for the same sustained G reason. I've heard no announcements of GD starting over with a clean sheet design. Alenia is looking for another prime to team with. So far no takers. And they don't seem to have tied in with a proven provider of simulator training, a very important piece to be missing.
Raytheon is reported to be the prime for Alenia with CAE providing the simulation and training expertise.
