A derelict Federation starship whose crew died when its prototype singularity drive failed, later used as a training ground where Academy and War College cadets are taken hostage.
The USS Miyazaki appears in the Starfleet Academy episode Come, Let's Away. The ship was testing an experimental singularity drive when a catastrophic failure killed everyone aboard, and the wreck was left adrift.
Cadets from Starfleet Academy and the War College are sent to restore power to the hulk as a joint crisis exercise. Caleb Mir brings back life support using programmable matter, but a cloaked ship delivers a boarding party of Furies, who throw the supervising officer out of an airlock and demand a ransom.
The cadets barricade themselves on the bridge. The Vulcan cadet B'Avi is killed protecting Caleb, and Tarima Sadal removes her inhibitor and uses her telepathy to save the others, who are beamed back to the USS Athena. The attack proves to be a diversion staged by Nus Braka.
