In the Universal Century timeline, the helium³ fuel used for power fusion reactors is mined from the atmosphere of the planet Jupiter. Moving this fuel to and from the Earth is the job of the Jupiter Fleet, using the massive, 2000 meter long Jupitris-class freighters, a fleet of energy transportation vessels. These ships could best be thought of as an equivalent of the modern day supertanker, as these are the largest ships built in the UC timeline and their role is not warfare, but cargo transportation. The Jupritris class, as mentioned above, is designed exclusively for the movement of large quantities of Helium-3, so the ships carry no weapons. While the class makes no mark in or on major battlefields, they have bred interesting characters, most notably Paptimus Scirocco, one of the main antagonists in Zeta Gundam. Scirocco was captain of the lead ship Jupitris, and joined with the Titans when he returned to the Earth Sphere in UC 0087. Even though his ship was an unarmed freighter, he continued to use it as his base of operations. It stayed well away from combat, but its huge cargo bays were used to carry and launch Scirocco's immensely powerful handmade mobile suits.
- An identical ship, the Tsiolkovsky appears in the Cosmic Era timeline of the Mobile Suit Gundam SEED series, as the first manned ship to Jupiter designed and captained by the first Coordinator George Glenn.
- Europa, a similar ship seen in Mobile Suit Gundam 00 The Movie -A wakening of the Trailblazer- pays homage to the Jupitris.
