Argus is an experimental stealth battlestar in operation at least six months prior to the end of the Cylon War.
The Colonial Fleet's Admiralty propositions William Adama to serve aboard the ship as a pilot, which he accepts; he serves along side his friend and higher ranking pilot, known by his callsign of "Lucky".
Argus is equipped with Stealth Vipers and her crew is considered by the Admiralty to be extremely loyal to the Colonies (Battlestar Galactica: Origins 5).
- In Colonial mythology, Argus is known as "the watchman".
