The Calypso-class exfiltration craft is a United Nations Space Command starship classification. These fulfill a purpose similar to Black Cat-class subprowlers, and were in use in the 2530s, notably in the Battle of K7-49, as it appears that Black Cats rendered these ships obsolete. By 2553 the Venezia Insurrectionist militia had acquired a few of these Calypso-class crafts. Staffan Sentzke suggested letting the Huragok Sometimes Sinks , to upgrade a Calypso-class craft.
- In Greek mythology, Calypso was a daughter of Atlas who imprisoned Odysseus for 7 years during his voyage home to Ithaca in Homer's epic, The Odyssey. This could possibly be one of Bungie's hidden 7 references.
