Aratrum

The Aratrum is a large, immigration vessel that was introduced in the 2017 Godzilla film, Godzilla: Planet of the Monsters.

The ship is captained by Unberto Mori, who, alongside the Committee, all work together as a collective to ensure the betterment and survival of the three species on the ship. Those being humanity, the Exif, and the Bilusaludo.

Appearance
The Aratrum bears a relatively bare appearance, featuring a gray, square build. The circular placement of the ship's engines is a defining feature, with eight being placed around the aft of the ship.

Godzilla: Planet of the Monsters
The Aratrum was introduced early on in the film during a monologue by Haruo Sakaki. It played a minor role in the film overall, but did bring the remaining population back to Earth.

Following the return to Earth, it would remain in orbit around the planet, with the only means of returning to it being the landing ships, which were all seemingly destroyed by Godzilla Earth, following his awakening.

Exosuit
Exosuits were kept in large hangers in the Aratrum for use in planet-side operations. Yuko Tani would tend to them during the film, being part of the power suit team.

Gematron
Gematron is a guidance device that's described as not being bound by time or distance, only power from the ship's nuclear energy, which is what enables travel over long distances.

Landing ship
Landing ships are present on the Aratrum in large numbers, and were utilized to make landfall on Earth once again.
