Calypso-class exfiltration craft
The Calypso-class recovery dropship is a robust troop transport designed for rapid transfers and exfiltration. They are one of the smallest UNSC craft to be equipped with a slipspace drive, which is powerful enough for a short and quick jump but not capable of longer transitions; however, they are still capable of crossing modest interstellar distances. Calypsos are more forgiving of a pilot under fire than a Pelican due to their rudimentary design. However, being designed for speed rather than comfort, they are also exceedingly uncomfortable for the occupants, particularly when jumping into slipspace.
Entering service around the 2520s, Calypso-class exfiltration craft were in use in throughout the Human-Covenant War, most notably during Operation: PROMETHEUS in 2537. In late 2552, a Calypso exfiltration craft was dispatched to transport ONI agent Connor Brien off a Covenant-occupied Beta Gabriel, where Brien had been observing a Jiralhanae pack. They were considered outdated by 2553. By that year, the Venezian militia had acquired a few of these craft. Staffan Sentzke suggested letting the Huragok, Sometimes Sinks, upgrade one of the militia's Calypsos.
In Greek mythology, Calypso was a daughter of Atlas who imprisoned Odysseus for seven years during his voyage home to Ithaca in Homer's epic, The Odyssey. This could be a reference to the number seven.
