  EELV Program Reaches Maturity - By Marco A. Caceres - Military Aerospace Technology
EELV was first conceived in 1994, following a four-month study by a Pentagon task force charged by Congress (in the fiscal year 1994 Defense Authorization Act) to come up with a plan to modernize U.S. space launch capabilities.
EELV was the result of the realization with DoD that there was simply not enough money in the budget for a completely new launch vehicle.
EELV provides DoD with a wider range of alternatives for launching its payloads, which means greater pressure for both the Atlas V and Delta IV rockets to perform as expected.

 EELV - Wikipedia, the free encyclopedia
The Evolved Expendable Launch Vehicle (EELV) program was a United States government, primarily a Department of Defense–sponsored effort to develop at least one family of space launch vehicles, that would meet the long term needs of the military.
After the U.S. Air Force assembled its initial blue print for the EELV in 1994, following many years of government funded studies into an improved system and architecture, which was intended to replace all if not most existing “legacy” spacelifters (e.g.
The architecture called for the spacelifter to be based on standardized fairings, liquid core vehicles, upper stages, and solid rockets.

The EELV is a rocket launch vehicle system, such as the Atlas or Delta rocket system, which is used for the transportation of commercial satellites into space.
In 1997, the Air Force announced that it wanted to procure EELV services from both Boeing and Lockheed Martin, and that it wanted both aerospace companies to invest their own money in the EELV program because there was a potential for substantial profits to be made by using EELVs to launch private communication satellites.
The USAF EELV analysts determined that, had they known that Boeing EELV personnel had possession of proprietary Lockheed Martin EELV documents in 1997, they would have immediately suspended the competition and conducted a thorough investigation into whether the procurement competition should be terminated.

 EELV: The Next Stage of Space Launch
In fact, the EELV System Performance Requirements Document listed only three "key performance parameters." These stipulated specific mass-to-orbit requirements for each class of vehicle, design reliability of 98 percent at 50 percent confidence level, and standardization of the launchpads and payload interface.
Both have achieved notable successes in their first launches, but the EELV program is still in its infancy, and will need continued scrutiny to ensure that the anticipated gains in cost and reliability will be realized over the long term.
Along with the improvements in performance, reliability, and operability, one of the most significant achievements of the EELV program was the development of a standard interface for all EELV payloads.

 EELV targets 2001 launch
"EELV will provide cost savings of at least 25 percent initially and has the potential to reach up to 50 percent over the life of the program," said Maj. Tom Steele, EELV command lead for Air Force Space Command.
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.

 Emerging Concepts in the Evaluation of Ventilatory Limitation During Exercise: The Exercise Tidal Flow-Volume Loop -- ...
The MVV is performed at high lung volumes (increased EELV) resulting in a high elastic load to breathing and requires large expiratory pleural pressures to obtain the high flows early in expiration (increasing the WOB).
In contrast, during exercise, EELV is reduced resulting in tidal breathing occurring at a more optimal position of the pressure volume relationship of the lung and chest wall with consequent less WOB (from R. Jorge Zeballos and Idelle M. Weisman, William Beaumont Army Medical Center, El Paso, TX).
EELV is reduced at rest and remains near RV throughout exercise despite significant expiratory flow limitation and apparent room to increase EELV to avoid the flow limitation.

 friendly printed version:Shenanigans with the EELV program
When the EELV program was first being discussed in the mid-1990s, the commercial launch industry was soaring.
So the two competitors for the EELV program, Lockheed Martin and Boeing, figured that they could offer cheap launches to the military and make up their costs in the commercial sector.
As it stands, the EELV program seems like nothing more than a boondoggle designed to bolster a crumbling domestic industry that is rotting out from the inside.

Included in the classified information is financial data necessary for anyone outside the EELV program to find out if the government really will save as much as the Defense Department and the contractors say.
The Defense Department inspector general also challenged whether there was enough "visibility" into the program's spending in its 1999 review of the EELV program, according to the agency's Congressional testimony.
But in the space-launch business, the government has spent billions of dollars on projects, from the proposed Freedom space station to several X-planes, in which the spacecraft were never even delivered.

 United States District Court, C   (Site not responding. Last check: 2007-10-14)
Boeing responded to Lockheed's allegations of trade secret theft and anticompetitive conduct by counterclaiming that Lockheed had made false and misleading statements to the government during the EELV procurement process relating to Boeing's conduct, and that Lockheed was engaged in an unlawful pattern of conduct to inflict reputational and competitive harm on Boeing.
In particular, Boeing and Lockheed threatened either to boycott the EELV procurement or to withdraw from the EELV business if the Air Force did not grant the companies government subsidies that cover the majority of their costs in the form of cost-plus infrastructure contracts and long-term exclusive launch contracts and launch allocations.
By foreclosing competition for government EELV launches, and by using their market power to demand that the U.S. Air Force deal with Defendants on common terms to subsidize their EELV businesses and exclude competitors, Defendants also have significantly injured competition in the sale of EELV-class vehicles and related launch services to commercial customers.

In the eyes of the organization, the Air Force is "propping up failing ventures with lucrative long-term contracts, forcing taxpayers to fund the EELV boondoggle for years to come" by endorsing the formation of the ULA and awarding it contracts for a new round of EELV launches.
If the EELV's are uneconomic, just think about the costs of NASA's two proposed Shuttle-derived missiles, given that the number of yearly launches of these is likely to be small -- and that these two notionally Shuttle-derived vehicles are really quite different missiles, which will require separate, bespoke launch pads.
Economy is an important reason why the EELV's also need to be combined with whatever launch missiles NASA hopes to have after the Shuttle is retired.
