Talk to me ... Cardinal????

Arizona superstar David Johnson did his best "Top Gun" impression Tuesday ... hitting up Luke Air Force Base to copilot an F-16 -- and the video is awesome!

Unclear exactly why he was there during game week ... but the 6'1", 224-pound RB stuffed himself into the back of a jet anyway ... and was DEFINITELY nervous as hell for it all.

"Pray for me," D.J. said before take off.

Don't worry AZ fans ... David met a better fate than Goose -- making it back to the ground just fine.

As for the dudes at the base ... they were jacked up about the experience, tweeting, "We had a blast hosting @DavidJohnson31 today and showing him how we train the world’s greatest fighter pilots!"

Beach volleyball training next??
