Einstein (NCC-1701/6)

Einstein (NCC-1701/6) was a Class F shuttlecraft assigned to the USS Enterprise (NCC-1701).

In 2267 the Einstein was taken by Commodore Matt Decker and piloted into the maw of a Doomsday machine in an attempt to destroy the automated planet destroying vessel. The Einstein and Decker were destroyed in the attempt but did inspire a successful attack on the planet killer shortly after. (TOS episode: The Doomsday Machine)

Background
In it's original presentation in "The Doomsday Machine" the shuttlecraft was reused footage of the Galileo (NCC-1701/7) from "The Galileo Seven". In the remastered version of "The Doomsday Machine" the original footage was replaced with new imagery of the Einstein (NCC-1701/6), this was preceded by an image by Adam "Mojo" Lebowitz in Ships of the Line which also showed the shuttlecraft sporting the NCC-1701/6 registration.
