HA'TAK
A Goa'uld mothership, tetrahedral in shape. Ha'taks facilitate the transport of Goa'uld and their Jaffa armies. They are also significant forces in attacking worlds from space, but are capable of atmospheric flight and landing on a planet's surface. (Typically, pyramids are utilized as landing platforms.)
The Ha'tak is armed with powerful energy weapons, shields, ring transporters, and are capable of launching entire squadrons of death gliders. It utilizes crystal-based technology for ship's functions, and is built around a centralized engine room and a command bridge -- called the Pel'tak.
