Al'kesh

In Stargate SG-1 the al’kesh is a powerful bomber used in bombardments of areas. It is powerful enough to penetrate and collapse the Tok'ras' underground crystal tunnels. It is also a light troop transport ship used to land Jaffa on a planet to enslave or to kill the inhabitants of a planet.

It is also the class of vessel that Osiris had cloaked in orbit while she beamed down to Earth to probe Daniel Jackson’s mind while he slept to get him to subconsciously decipher the text on an ancient tablet.
