A Starfleet freighter under Captain O'Shea that was attacked by Orion pirates while carrying dilithium and the drug needed to save Spock's life in the animated series.
The Huron appears in the animated episode The Pirates of Orion. Spock has caught choriocytosis, harmless to humans but fatal to Vulcans, and the only cure is strobolin. The USS Potemkin hands a supply to the Huron, which is to meet the Enterprise halfway.
Before the meeting an unmarked ship overhauls the freighter, cripples it and takes both the drug and its cargo of dilithium. The Enterprise finds the Huron adrift with its crew hurt and follows the raider's trail to an asteroid field. The thieves are Orions, whose government claims neutrality and whose crews are expected to die rather than be caught. Kirk beams down for an exchange, foils the Orion captain's plan to blow up both parties and recovers the strobolin in time.
