The Shinyo Maru was a ship of unknown class privately-owned by the Weyland-Yutani Corporation. It was the second vessel that rediscovered the derelict ship on Acheron (LV-426) following the disastrous mission to Hadley's Hope in 2179. It was sent to ascertain the status of the Atmospheric Processing Plant.
- The Shinyo Maru shares its name with the SS Shinyo Maru, a Japanese cargo steamer from World War II notable as the site of a massacre in which almost 687 America prisoners of war were killed by their Japanese captors.
- Its name is also similar to that of the Piper Maru in Alien vs. Predator.
