The notation on the graphic is for a MK-IX/01 Constitution
-class starship. I think the idea for the graphic was to show Khan reading up about the kind of ship he finds himself aboard. If that's what the graphic was meant to convey than at least as far back as "Space Seed" the Enterprise
is supposed to be a Constitution
-class ship. And the /01 added to the MK-IX might be supposed to mean the graphic is of the Enterprise's
primary phaser. The same thinking could be in effect when the graphic finally shows up onscreen in "The Trouble With Tribbles."
