Osiran war missile

An Osirian War Missile was a piece of Osirian technology used to attack targets from astronomical distances.

Using a form of Pyramid power as an energy source, the missile could be assembled from numerous components by service robots. It resembled a small pyramid on a platform, but was large enough for a servitor to enter and stand upright. (DW: Pyramids of Mars)

While Sutekh himself was trapped in Egypt, unable to move, he was able to construct a War Missile in England with the help of Marcus Scarman's re-animated corpse and a small number of servitors sent through a time-space tunnel.

His plan was to use the missile to annihilate the pyramid on Mars that housed the Eye of Horus, thus freeing himself from captivity.The Doctor, disguised as a servitor, was able to place a box of gelignite on the ramp of the missile. Sarah-Jane Smith then managed to detonate the box with a rifle shot.

Sutekh immediately noticed the explosion and was able to contain it through sheer force of will, but this required a tremendous effort. The Doctor travelled down the time-space tunnel and momentarily broke Sutekh's concentration by whispering his name. The box exploded, taking the missile with it and forcing Sutekh to alter his plan.
