The Chiroptera-class stealth vessel was a classification of small stealth ships used by the Office of Naval Intelligence of the United Nations Space Command in service in the early 2500s.[2]


These ships were roughly 50 meters long with oddly-angled black stealth surfaces and carried advanced counter-intrusion software. Notably, the class used the smallest operational slipspace engines ever produced by the UNSC. They are described as having prominent wings that give it a decidedly bat-like appearance.[2]

However, without a standard central controlling AI, the sensitive components tended to become unreliable. The resulting breakdowns resulted in the entire class being decommissioned around 2512. Vital components were removed, and the slipspace drive was locked down.[2]

At least one vessel of this class, belonging to Governor Jacob Jiles, was in the hands of the Eridanus rebels.[3] This ship, the Beatrice, would later be stolen by Dr. Halsey and used to transport herself and Kelly-087 via Slipspace jump to Onyx, where it was shot down by the Onyx Sentinels.[4]
