Another battleship is known to exist, commanded by a duplicate Elizabeth Weir. The Daedalus and the Apollo destroyed a few of them, and the rest are destroyed in the explosion of Asuras. In season 4, it is revealed that the Asurans have built 38 Aurora-class battleships for their war with the Wraith. It is later destroyed as a result of a stargate explosion in episode "The Lost Tribe". The Travelers take control of a derelict battleship with Sheppard's help in "Travelers". The battleship Tria is encountered along with its Ancient crew in "The Return". Zelenka brings the weapons online at the cost of the shields, and the Orion manages to destroy one hive ship before being destroyed herself. The Orion is barely operational when it is called upon to intercept two Wraith hive ships heading for Earth. The Atlantis Expedition gains control of an Aurora-class battleship discovered by the Taranians in "Inferno" it is named Orion by John Sheppard (who dislikes its original name Hippaforalkus). In that episode, the Aurora is a crippled battleship whose crew have preserved themselves in stasis pods, which self-destructs to avoid falling into the hands of the Wraith. The Aurora-class battleship is a warship used by the Ancients at the time of their war with the Wraith, first seen in "Aurora". Jumpers are also equipped with a cloaking device to evade enemies which renders the ship effectively invisible to both the eye and most sensors. Puddle Jumpers are armed with drone weapons capable of destroying larger ships. Access to the Jumper is provided by a rear ramp-hatch. The interior of the Jumper is divided in two parts: cockpit and aft the bulkhead door between the two sections is airtight and can hold even against the pressure of deep ocean.


Jumpers are cylinder-shaped with two retractable engines, one on either side, so that they can fit through the Stargate device. The Jumpers are used by the humans from Earth that traveled to Atlantis so that they can travel to other planets as well as navigate the planets once they arrive-both in the air and underwater. Puddle Jumpers were created by the Ancients and most exist within the city built by the Ancients known as Atlantis. The Puddle Jumper or Jumper is a small spacecraft used extensively in the Stargate Atlantis series. Duplicates of these ships are utilized by their nanite creations, the Asurans, as they also possess knowledge of Ancient technology. The Ancients are one of the most technologically advanced races in Stargate, and this is reflected in their starships.
