'Rogue One: A Star Wars Story': Classic X-Wing Pics ... So it Seems

"Star Wars: The Force Awakens" is still in theaters -- but we already have major clues about "Rogue One: A Star Wars Story," a prequel to the original, 1977 'Star Wars.'

TMZ has obtained pics of what appear to be a classic X-Wing -- the Rebel fighter plane Luke Skywalker famously used to destroy the Death Star.

The new film will reportedly follow a group of resistance fighters attempting to steal plans for the Death Star.

Check out the pics ... this X-Wing has 4 engines, just like the original planes. The X-Wing featured in 'The Force Awakens' is a newer plane with 2 engines.

The pics were snapped at Pinewood Studios where the 'The Force Awakens' was also filmed.

'Rogue One' will be released December, 2016.
