Overall view of the aft unit.

While the aft unit and warhead section are fastened together throughout the entire launch and flight phase, the aft unit proper begins at the seam between two rows of rivets (just forward of the ball fitting access door and the "CG Body Empty" stencil).

Note the large instrument compartment access door and the smaller skirt section access door (farther aft, just forward of the gold component).
