NCC-1701/12

NCC-1701⁄12 was a Federation shuttlecraft that was in service with Starfleet in the mid-23rd century, attached to the USS Enterprise (NCC-1701).

In 2269, when the Enterprise was studying a Class M planet orbitting a binary sun, Harry Mudd stole Shuttlecraft 12 with Nurse Christine Chapel as a hostage. On the planet's surface, he intended to strand her forcing the Enterprise's crew to rescue her while he escaped in the shuttle. His plan backfired when a native rock creature crushed the vehicle with one of its feet. 

Background information
The NCC-1701⁄4 and another shuttle in the Enterprise's shuttlebay were of the same design as NCC-1701⁄12.

There was no name for this shuttle printed on the hull, and was only referred to as "shuttlecraft" in the episode dialogue.

The shuttle was labeled as N.C.C.⁄1701⁄12 or N.C.C.-1701⁄12 in some scenes.

The Copernicus seen in was presumably the replacement shuttle for this shuttle, since both craft shared the same registry number.
