Shakri ship

This Shakri Ship was the ship used by the specific holographic image of a Shakri. It was used to deposit small black cubes on the Earth's surface in order to confuse humans and then kill them by inducing heart attacks in anyone within range.

The Ship was connected to Earth using a Transmat beam from seven different places on Earth. The Eleventh Doctor and his companions Amy Pond and Rory Williams used the one closest to them in London, which was hidden inside a disused lift. (TV: The Power of Three)

This ship was destroyed at the end of the episode as a side effect of the Doctor using the cubes to revive all the humans who had suffered heart attacks.
