The EELV competition was expected to produce the next generation of launch vehicles to replace all medium to heavy launchers, Lockheed Martin's Atlas, Titan II and Titan IV series, and McDonnell Douglas's Delta series, with a single family of vehicles capable of launching medium and heavy payloads into orbit at a significantly lower cost. If that was the case, then the Air Force will have developed a new family of launch vehicles that would be primarily used only for national security payloads, resulting in higher overhead costs to DoD, while missing an opportunity to maximize the competitive posture of US industry.

The Governments objectives were to develop Payload Category A, B, and C launch system prototypes, through shared investment with industry partners that will lead to EELV certified launch systems capable of providing launch services for all EELV-class National Security Space (NSS) missions. The ESPAStar platform's 6 payload ports are capable of accommodating any combination of up to 6 hosted and 12 separable (fly-away) payloads (maximum 1 hosted or 2 separables per port).
