Evolved Expendable Launch Vehicle Secondary Payload Adapter System Interface Specifications For . After many years of government-funded studies on the subject of modernized launch vehicle systems, the Air Force finally developed a "roadmap" in 1994 for the acquisition of Evolved Expendable Launch Vehicles (EELVs) to replace the DELTA IIs, ATLAS IIs, and TITAN IVs then in use at Cape Canaveral. EELV was important not only to reducing the launch costs of the Department of Defense, but also to the continued world-wide competitiveness of the US commercial launch industry. endobj This would be difficult to achieve since projections showed that the EELV would not be able to meet the requirements of as much as 42 percent of the estimated commercial market.
