They are retiring the T-1 and 'big wing/heavy' jet pilots now go directly from T-6's to the FTU's (RAG) to train on their 'fleet' aircraft with some sim time in between I believe. I asked some pilots from a squadron I deal with about it and they said there was a noticeable difference in the quality of pilots coming out of the 'new and improved' training (I am...shocked), with a lot more training needed at the operational squadron level to get them up to speed when it was not needed before.
Fighter pilots still go through T-38's, and and now those are picking up some of the slack for the 'heavies' now apparently.
Same general story though, with the services trying to train pilots by doing more with less' and the product may be suffering as a result from what I've read here and talking to USAF pilots having to deal with the product from their own version.
