	EELV targets 2001 launch
		The future system will use standardized launch vehicle families instead of different versions of three heritage systems, a single launch pad design, design reliability and completely standardized set up and launch procedures and equipment.
		EELV design and development began in 1995, with the first commercial launch planned for 2001 and the first government (medium lift) launch set for the following year.
		EELV represents a major step forward in the commercial use of space and ensures the Unites States remains a world-class commercial space launch provider, according to Steele.

	Fact Sheet - EVOLVED EXPENDABLE LAUNCH VEHICLE (Site not responding. Last check: 2007-10-21)
		The mission statement for the EELV program is: “Partner with industry to develop a national launch capability that satisfies both government and commercial payload requirements and reduces the cost of space launch by at least 25 percent.”.
		The EELV program’s two primary objectives are to: 1) increase the U.S. space launch industry’s competitiveness in the international commercial launch services market and 2) implement acquisition reform initiatives resulting in reduced government resources necessary to manage system development, reduced development cycle time, and deployment of commercial launch services.
		EELV phase three began in October 1998 with both Boeing and Lockheed-Martin each being awarded a Development Agreement and an Initial Launch Services (ILS) contract for a total of $3.0 billion worth of contracts.

	Nat' Academies Press, From Earth to Orbit: An Assessment of Transportation Options (1992)
		These vehicle and infrastructure shortcomings were largely hidden as long as the United States had a near monopoly on space launch capability, but they have now emerged as severe detriments to the health of the U.S. space launch industry from the perspectives of global competitiveness and the ability to meet national needs.
		LAUNCH VEHICLE AND PAYLOAD ATTRIBUTES A long-term commitment to a new family of vehicles with many common components and a new, flexible support infrastructure is vital to the U.S. civil and military space program.
		To provide higher launch rates, both the vehicles and the launch complex should be designed for ITL (integration, transfer, and launch) operations, with off-line integration and processing of the ELV and the payload.

	EPA: Federal Register: Notice of Intent To Prepare an Environmental Impact Statement; Evolved Expendable Launch Vehicle ...
		The EELV would be an unmanned, expendable space launch vehicle evolved from existing systems capable of launching Department of Defense (DOD), National Aeronautics and Space Administration (NASA), other government, and civil satellites, including payloads up to 45,000 pounds.
		EELV would be DOD's sole source of expendable medium and heavy spacelift transportation to orbit through 2020.
		EELV launch activities would occur at Cape Canaveral Air Station (AS), Florida, and Vandenberg AFB, California, from existing space launch complexes that would be modified to meet program requirements.

	Shuttle II
		The augmentation approach used in the Shuttle II studies is not unlike the Ariane 4 expendable launch vehicle which can be launched without boosters or, for heavier payloads, can use 2 or 4 solid and/or liquid boosters, thus tailoring the launch system to meet the payload delivery requirements.
		The intent was to decouple the processing of vehicle and payload elements with assembly of the PCS to the orbiter late in the ground processing flow.
		This included a smaller Shuttle II glider launched by a reusable booster and expendable core stage, the glider launched by a two-stage expendable, and a two-stage airbreather/rocket system that took off horizontally (a placeholder drawing of the vehicle was used until a system was defined).

	Why Are Launch Costs So High (Site not responding. Last check: 2007-10-21)
		While the OSP was not itself a launch vehicle, in combination with an existing expendable launch vehicle, it was intended as a replacement for the Shuttle, as well as probably serving as a Space Station lifeboat.
		Launch vehicle designers are thus forced to sacrifice simplicity, damage tolerance, maintainability, etc., in order to achieve a reasonable payload mass.
		Expendables inherently lack intact abort capability, and often carry frightfully expensive payloads, sometimes on the order of $1 billion, in addition to the launch cost in the tens or hundreds of millions.

	Mars Reconnaissance Orbiter: The Mission
		The launch vehicle supplies almost all the energy that the spacecraft needs in order to get from Earth to Mars.
		This launch vehicle was selected because it provides the performance needed to fly a large spacecraft to Mars in the 2005 launch period.
		Although the geometry of Earth and Mars permit missions to be launched every two years, the 2005 mission requires more performance than for 2003 and 2007 launch dates given the position of the planets in their orbits.

	EELV - Wikipedia, the free encyclopedia
		The United States government–sponsored Evolved Expendable Launch Vehicle (EELV) program was intended to develop affordable alternatives to legacy medium-to-heavy-lift launch vehicles (e.g.
		It was presumed that the commercial launch market would support two new vehicles, but demand in the first half of the 2000s has been lower than expected, due to the downturn in the commercial spacecraft market during that time, and a perceived trend toward smaller spacecraft.
		If market conditions do not improve, the Department of Defense may eliminate one of the EELV competitors in 2009.

	SPACE.com -- Air Force Evolved Rocket May Restore U.S. Launch Leadership
		The new rockets, families of space carrier vehicles each designed by the two largest U.S. space booster companies, Lockheed Martin and Boeing, are designed to eventually replace today's existing fleets of Delta, Atlas, and Titan boosters by the middle of the next decade.
		Considering the current series of launching disasters that have nearly grounded most U.S. satellites since spring, the coming of the EELV (Evolved Expendable Launch Vehicle) might not be a moment too soon for U.S. space launch leadership.
		But the fleet of four NASA shuttles proved unable to carry out as many annual launches as would be needed to be the sole U.S. carrier rocket, so the Reagan administration restored commercial rockets as alternatives to the shuttles in 1985.
