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.
The Ship was connected to Earth using a Transmat beam from seven different places on Earth. The 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)
