Overall view of the Atlas' engines.

The Atlas used a "stage and a half" configuration: All three engines were ignited at launch, and after a period the outer two engines (called booster engines) were jettisoned, leaving only the center engine (called the sustainer engine). Jettisoning the booster engines improved the mass ratio, allowing a higher payload.
