In the 1985 film Day of the Dead, what underground facility shelters the surviving humans?

In the 1985 film Day of the Dead, surviving humans shelter in a military bunker.

The facility is an underground missile silo in Florida, occupied by military personnel and scientists after a zombie apocalypse has overwhelmed much of the world. The bunker’s confined structure intensifies the conflict between the soldiers, who favor force, and the researchers, who study the undead.

The film was written and directed by George A. Romero and is the third released entry in his original Dead series, following Night of the Living Dead and Dawn of the Dead. Much of its drama centers on Dr. Sarah Bowman, helicopter pilot John, communications specialist Bill McDermott, and scientist Dr. Matthew Logan.

The bunker is sometimes confused with the shopping mall in Dawn of the Dead, where survivors hide in the earlier film. Day of the Dead instead emphasizes scientific experimentation, military authority, and the possibility that zombies can learn.
