The Ba Sing Se airships are large, metal, zeppelin-like vehicles manufactured by Cabbage Corp for the Earth Kingdom military and constructed of cheap materials. They can be maintained by a small crew of four: a pilot, a co-pilot, an engineer, and a soldier.
In 171 AG, the military used a Ba Sing Se airship to transport Avatar Korra and Asami Sato from Fort Bosco on the outskirts of the Si Wong Desert to Ba Sing Se. Asami instantly recognized the cheap materials and used the knowledge to break free from her restraints. While flying over the fourth quadrant of the desert, Korra destroyed the ship's controls and the vessel crashed into a sand dune. Although the crew, aided by the girls, managed to repair the ship to workable conditions, it was entirely destroyed by a sand shark before they could escape. The remaining scraps of metal were salvaged and transformed into a makeshift sand-sailer, which Korra propelled toward the Misty Palms Oasis.
Following Zaheer's assassination of Earth Queen Hou-Ting and the ensuing anarchy in the Earth Kingdom capital, many of the airships on the palace grounds were either commandeered or stripped by looters. Mako and Bolin took control of one of the airships in order to deliver Zaheer's ultimatum; though some parts of the craft, including the radio, had been ripped out, the ship was still functional. They first used the airship to rescue their extended family in Ba Sing Se before searching the Si Wong Desert for Korra and Asami. Upon finding the wreckage of that airship, they followed the sand-sailer trail back to the Misty Palms Oasis and reunited with the girls. Team Avatar, along with Tonraq, Lin, Zuko, and Mako and Bolin's family, began a journey to Zaofu through the air.
Meanwhile, the Red Lotus used another Ba Sing Se airship to journey to the Northern Air Temple. While her allies dealt with capturing the temple's occupants, P'Li remained aboard and circled the temple to provide them aerial support. After cornering all the airbenders, P'Li ushered them in the airship and brought them to a set of Air Nomad caves a few miles away from the temple, before returning and taking Zaheer toward the top of Laghima's Peak, where they awaited the arrival of Korra. When Zaheer tried to lead Korra onto the airship, Tonraq intervened and cut the ropes tying down the ship, leaving it to drift aimlessly in the currents.
The design of the Ba Sing Se airship is identical to that of the police airships used in Republic City, save for the Earth Kingdom paint job. Each of these was in turn inspired by the Fire Nation airships used during the final stages of the Hundred Year War. Asami stated that these airships were cheaper and less sturdy than those manufactured by Future Industries.
