Fictional service history and disposition[]
In the 1950s decade, Yakutsk was operated by pirates and commanded by Señora Yma Árbol. Yakutsk was used to plunder and sink seagoing vessels in the Caribbean. The pirates discovered the sunken city of Atlantis and used it as a secret base to dock Yakutsk and organize their criminal operations.
Árbol commanded Yakutsk in a sea battle against the refitted sub USS Bengal, and was destroyed during the conflict. (Last Unicorn RPG - Holodeck Adventures module: Tigers of the Deep)
