About the EELV Program:





The EELV is a U.S. Department of Defense (DoD) program, which provides two families of launch vehicles, the Delta IV and Atlas V. The EELV system includes launch vehicles, launch capability, a standard payload interface, support systems, mission integration, flight instrumentation and range interfaces, special studies, post-flight data evaluation and analysis, mission assurance, assured access, system/process and reliability improvements, training, and technical support. The system also includes launch site/operations activities, activities in support of assured access, systems integration and tests, and other related support activities.

The EELV program provides the DoD, the National Reconnaissance Office (NRO), and other government and commercial purchasers with launch services for medium- to heavy-lift class satellites. As of December 2006, the United Launch Alliance (UAL), a Boeing and Lockheed Martin joint venture, is the sole provider of EELV launch services. ULA will assure access to space with two launch vehicle systems by combining Delta IV/Atlas V management and engineering in Denver, Colorado; combining most of the manufacturing in Decatur, Alabama; and combining launch teams at both launch sites.

The EELV program funds a total of 152 launches including launch vehicles and launch services. Air Force missions make up 91 of the 152 launches. The remaining missions include funding and quantities from other sources to include the NRO, the U.S. Navy, and one purchase by the Australian Government. Navy funding is for the launch of 11 Mobile User Objective System (MUOS) satellites.



Delta IV Launch Vehicle:

Developed in partnership with the U.S. Air Force EELV program, the United Launch Alliance Delta IV Family of launch vehicles combines design simplicity, manufacturing efficiency, and streamlined mission and vehicle integration to launch high-priority Air Force, National Reconnaissance Office (NRO), NASA, and commercial payloads to orbit. Operational Delta IV launch pads are located on both the East and West Coast with Space Launch Complex-37 at Cape Canaveral Air Force Station in Florida, and Space Launch Complex-6 at Vandenberg Air Force Base in California. The Delta IV launch system comes in five variants: the Delta IV Medium (Delta IV M); three variants of the Delta IV Medium-Plus (Delta IV M+); and the Delta IV Heavy (Delta IV H). Each variant is comprised of a common booster core powered by the Aerojet (GenCorp) Rocketdyne RS-68 main engine; a cryogenic upper-stage powered by the Aerojet Rocketdyne RL10B-2; and either a 4 or a 5 meter composite payload fairing.



Atlas V Launch Vehicle:

The United Launch Alliance Atlas V Family of Evolved Expendable Launch Vehicles (EELV) was first deployed in August 2002. Atlas V vehicles are launched from Space Launch Complex-41 at Cape Canaveral Air Force Station in Florida, and Space Launch Complex-3E at Vandenberg Air Force Base in California, thus providing launch pads on both U.S. coasts. The Atlas V has followed a carefully executed program of incremental improvements, which has resulted in a 100% mission success rate. The Atlas V Family provides the latest evolutionary versions of the Atlas launch system. It includes the flight-proven Atlas V-400 and Atlas V-500 vehicles. Atlas V uses a standard common booster core (powered by the RD-180 engine produced by Russian company NPO Energomash); up to five solid rocket boosters; either a single-engine Centaur or a dual-engine Centaur upper stage powered by the AeroJet Rocketdyne RL10A-4-2 engine; and either the Atlas heritage 4.2 meter payload fairing or the 5.4 meter Oerlikon.



Price/Unit Cost:

The price of a launch vehicle is $145.22 million in FY 2014.



Program Cost:

The total procurement cost of the EELV program is $68.72 billion (estimated by the DoD) + $1.96 billion in research and development (RDT&E) funds, which means the total estimated program cost is $70.69 billion (numbers are aggregated annual funds spent over the life of the program and no price/inflation adjustment was made).



Mission/Role:

The EELV program provides Delta IV and Atlas V launch vehicles and services for medium and heavy class satellite payloads.



FY 2014 DoD Program:

Funds the purchase of 5 launch vehicles and associated launch services and support activities.



FY 2015 DoD Program:

Funds the purchase of 3 launch vehicles and associated launch services and support activities. FY 2015 EELV procurement funds are used to acquire launch services to provide critical space support required to satisfy DoD, national security, and other government space lift missions while fostering interagency and commercial cooperation. Launch services include, but are not limited to, launch vehicle manufacturing, secondary payload standard service, launch propellants, independent mission assurance, evaluation and certification of potential new entrants including early integration activities and analysis/support. The Air Force is responsible for funding its own missions. All non-Air Force EELV launch services are funded within their respective entities (e.g. NRO, Navy, etc.).
