Stargate destroyer

A Stargate destroyer is a device used by the Ancients to destroy a Stargate. By sending a stream of energy through an outgoing wormhole, the device was capable of storing in the gates capacitors. However, if too much is stored, the gate will explode in a blast resulting in two to three thousand megatons, enough to wipe out all life on a planet the size of Earth. Anubis managed to locate one such device, and used it in an attempt to destroy the Tau'ri. However, Rya'c, piloting a stolen death glider, was able to destroy the device.
