Calypso-class exfiltration craft
From Halopedia, the Halo wiki
The Calypso-class Exfiltration Craft is a United Nations Space Command starship classification. These fulfill a purpose similar to Black Cat subprowlers, except were in use in the 2530s, notably in the Battle of K7-49. It appears that Black Cats rendered these ships obsolete. Template:UNSC Ships
