Otherwise identical to the Atlas IIIA, the Atlas IIIB improved performance by employing a two-engine Centaur upper stage, as opposed to a one-engine Centaur upper stage employed on the Atlas IIIA. The two-engine Centaur, featuring two RL-10A engines, could produce a thrust of 41,592 pounds, roughly double the thrust of a single RL-10A engine. In the new configuration, the Atlas IIIB was capable of carrying a 23,630-pound payload to Low-Earth Orbit or a 9,900-pound payload to Geosynchronous Transfer Orbit.
