Evolved Expendable Launch Vehicle
Abstract
The Evolved Expendable Launch Vehicle (EELV) program is a space launch system developed to provide two families of launch vehicles (for example Delta IV & Atlas V). The program satisfies the government's National Launch Forecast (NLF) requirements and reduces the cost of space launch by at least 25% over legacy systems. EELV is a launch service, not a weapon system, which is primarily funded with production funds. The program has developmental items including: qualification of the extended mission kit, fleet standardization of the RS-68 main engine upgrade, Pre-Planned Product Improvements to ensure sustainability (includes, but is not limited to, secondary payload adaptor standard service, Global Positioning System (GPS) Metric Tracking capability, development of replacement components, flight and ground instrumentation), special studies, and other related support activities. EELV is responsible for launching government manifested payloads, including those once supported by Titan II, Delta II, Atlas II/III, and Titan IV. Evolved from heritage expendable launch systems and new applications of existing technology, EELV supports military, intelligence, civil, commercial, and international partnership mission requirements. As of 21 August 2007, the EELV Program has formally entered the sustainment phase. As of 31 October 2007, Air Force Space Command formally extended the EELV Program an additional 10 years, from 2020 through 2030. This program element is in Budget Activity 5, System Development and Demonstration, because it supports development and demonstration of the EELV concept leading to deployment of a lower cost expendable launch vehicle system.
