Modular design to accommodate a full range of mission requirements
Atlas V uses a standard common core booster, up to five solid rocket boosters (SRBs), a Centaur upper stage in a single- or dual-engine configuration, and one of several sizes of payload fairings.
Centaur is the world's highest-performing upper stage. The pressure-stabilized tanks combined with the lightweight Aerojet Rocketdyne RL10C-1 engine provides industry best thrust-to-weight ratio. The stage has demonstrated long-coast relight capability that enables it to service any orbital need.
