The Argo was a Federation shuttlecraft of unknown class in service to Starfleet in the late 24th century. Designated as a heavy transport shuttle, the Argo was complemented with a four-wheel drive all-terrain vehicle. She was assigned to the USS Enterprise.
In 2379, the Argo was selected for a search-and-recovery mission on the planet Kolarus III. (TNG movie & novelization: Nemesis)
At some later point, the Argo and another shuttle of the same class participated in a geophysical mission in a planetary system. (Ships of the Line 2014)
