Supergate segment

From The Stargate Omnipedia

Supergatesegment2.jpg

Individual device, approximately ten meters long, self-propelled and capable of fitting through a standard Stargate. Eighty compose an Ori Supergate.

The sections appear to be self-guided and are virtually indestructible. A full collision with a Ha'tak destroys the ship but leaves the Supergate component entirely intact. This fact appears to indicate that the units do not account for obstructions between themselves and the positions in space where they wish to establish the Supergate.

KEY EPISODE

Beachhead - Following the Ori force field's completion countless components emerge through the Stargate to form the Supergate beyond the barrier.
