The Shinyo Maru was a ship of unknown class privately-owned by the Weyland-Yutani Corporation. It was the vessel that rediscovered the Derelict Ship on Acheron (LV-426) following the disastrous mission to Hadley's Hope in 2179.
At some point following the disastrous USCM mission to Hadley's Hope, the Shinyo Maru was covertly dispatched to LV-426 by Weyland-Yutani to investigate, operating under the command of Seiji Tanaka. Upon reaching the moon, Tanaka's team quickly located the Derelict and discovered that the ship was largely intact, despite the explosion of the Atmosphere Processor at the nearby colony.
- 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.
