CMA Argo

The Argo was a UNSC scout ship. Though small, it was equipped with a Shaw-Fujikawa Slipspace Drive.

It was sent to the Harvest system in 2525 after the UNSC lost contact with that world. It sent a signal back informing it's location after dropping out of Slipspace, (presumably to aid in further increasing Slipspace jump accuracy), but after that nothing was heard from it. It met a Covenant cruiser in orbit, still in the process of glassing Harvest, and was destroyed. JOTUNs under the control of Mack, Harvest's agricultural AI, witnessed the Argo enter orbit, and tried to warn them off, but, with communications options limited, Mack was unable to warn them in time. This same cruiser stayed in orbit, and was met by the UNSC Heracles battle group a few months later.

Trivia
The ship was presumably named after the Argo, Jason's ship in Greek Myth, said to have been planned or constructed by the goddess Athena, and on which Jason and the Argonauts sailed to Colchis retrieve the Golden Fleece.
