The Argo was designed with recessed warp nacelles and fold-down wings. These wings were designed to assist in atmospheric maneuverability.
The shuttle was equipped with an all-terrain buggy that could transport up to three passengers over rugged terrain. The buggy was secured aboard the shuttle's cargo hold via wheel clamps. The shuttlecraft could also be remote controlled from a device on the buggy.
The Argo was designed by FX artist John Eaves. Eaves classified the Argo as a heavy transport shuttle. 
In Greek mythology, Argo was the ship on which Jason and the Argonauts sailed from Iolcus to retrieve the Golden Fleece.
The Argo makes an appearance in the Star Trek: Ships of the Line (2011) calendar for the month of December. In this illustration, painted by John Eaves, the Argo was on a landing vector for the main shuttlebay of the Enterprise-E.
