Remember the writers room thing? One of the ideas was Operation Skyfire which would of been a movie taking place during War World 2 and presumably by the name Skyfire would of been the main character perhaps and probably a different character from Jetfire from ROTF, while a whole movie didn't pan out it did influence the WW2 flashbacks in The Last Knight.
These pictures were in the bonus features but I think this is the first clear picture of them.
This was uploaded on the Artstation of JP Targete and here are his words on the artwork.
"A few years back me and a few other concept artist were invited by Paramount to participate in the "Transformers writer's room". We were there to help the writers visualize their unique "Transformers" movies. The results were exciting and fresh and gave a "new" take on the Transformer's Mythology. The images you see are a result of one of the "Transformer MOVIES" That was presented to Paramount and Steven Spielberg. The images can be seen on the special features of the "Transformers The Last Knight" Blue-ray. I was honored to be a part of this."
which to be fair, we have already... Between all the movies!)
