Jathaa sunglider
The Jathaa sungliders were large, black, saucer-shaped crafts employed by the Jathaa when visiting Earth. They moved via a smaller rotating platform of some sort underneath, and contained powerful weapon systems, utilising five energy beams that converge into one powerful beam capable of disintegrating a Sycorax asteroid ship into ash.

History
In 1997, the Torchwood Institute shot down one of these craft over the North Sea, and by 2006 they had managed to reverse-engineer the weapons system. (TV: Army of Ghosts) At Christmas of that year, they were ordered by Prime Minister Harriet Jones to use the weapon against the Sycorax spaceship that threatened Earth at the time.

When the Cardiff rift fractured, mixing space and time periods, Jathaa ships appeared and hovered over the Taj Mahal. (TV: End of Days)
