The MCRN Tsuchi is a Corvette-class light frigate in the Martian Congressional Republic Navy.


Tsuchi was stationed aboard the MCRN Bellaire.


When Bobbie Draper Books • TV began researching discrepancies in the disposition of Martian ships and equipment, she investigated the Tsuchi. According to official Martian Congressional Republic Navy records, the ship was decommissioned following the events at Io. A year later, sensor data showed the ship's transponder was active near Europa.[1].
