The Lockheed Martin Atlas III was an American orbital launch vehicle, used between 2000 and 2005. It was the first member of the Atlas family since the Atlas A to feature a "normal" staging method, compared to the previous Atlas family members, which were equipped with jettisonable engines on the first (sustainer) stage.
The Atlas III consisted of two stages. The first stage was new, but the upper stage was the Centaur, which has been used on most American launch vehicles since the 1960s, and is still in use today on the Atlas V EELV.
