This Nike Hercules missile is in the magazine, on the elevator. The yellow and black striped area is (one half of) the elevator door.
The missile is actually belly down, it flies in this attitude. The missile itself is white, the booster is green. The little fins in front of the big fins house the missile antennas which listen for the Missile Tracking Radar commands and echo back a radar pulse for easier tracking.
There is a launcher mounted on the elevator (very hard to see in the shadows). Missiles can be fired from this launcher as well as 3 other launchers on the surface.
