Orbital launch vehicle. Year: 1990. Family: Atlas. Country: USA. Status: Out of production.

The Atlas I launch vehicle was derived from the Atlas G, and included the same basic vehicle components (Atlas booster and Centaur upper stage). Significant improvements in the guidance and control system were made with an emphasis on replacing analog flight control components with digital units interconnected with a digital data bus. The first flight of an Atlas I was on July 25, 1990. Originally, 18 Atlas I vehicles were planned for manufacture. With the award by the USAF to General Dynamics of the MLV-II vehicle development contract for the Atlas II launch vehicle, the Atlas program rescoped Atlas I production commitments to 11 vehicles and converted the remaining commitments to the Atlas II/IIA/IIAS production effort.
