The OC Tiradosir, meaning "Rapacious" in the Orion language, was an Orion starship, a scout ship/marauder/privateer in Orion Colonies service in the 2270s decade. (FASA RPG module: Orion Ruse, ST video game: Trexels mission: Skirmish)


Around stardate 73XX.6 (circa 2270), the Tiradosir was rated a tier 1 marauder. It featured room for two officers and slots for two weapons or additional systems. Its deflector shields were rated 85, while the structural integrity field, or hull strength, topped at 235. (ST video game: Trexels mission: "Skirmish")


As part of Federation Starfleet operations in the Trexelian Expanse, the OC Tiradosir participated in the war games conducted by Starfleet and allied vessels from the 23rd and 24th centuries. (ST video game: Trexels mission: Skirmish)

The Tiradosir also saw action in conflicts with the Klingon Empire and Cardassian Union. (ST video game: Trexels mission: Events)

The Orion pirate Skevar began his career as an apprentice engineer on the Tiradosir. The privateer was engaged in a feud with another Orion pirate vessel when Skevar sabotaged his own ship's warp drives. He transported across to the other vessel, seconds before the Tiradosir exploded. Skevar was rewarded for his treachery, but became unemployable as an engineer. (FASA RPG module: Orion Ruse)
