Vehicles are defined by the number of solids and the width of the payload fairing. Program cost savings are achieved through operability improvements such as the use of common components and infrastructure, a standard payload interface, standardized launch pads and reduced on-pad processing; and acquisition improvements such as launch vehicle block buys. [46] As of 2019, Blue Origin expected a first launch of New Glenn in 2021.

[14] The USAF moved 7 launches from Delta IV to Atlas V.[15] To end litigation and competition for a limited market, both companies agreed to form the United Launch Alliance (ULA) joint venture.

The platform is optimized for GEO missions, but is adaptable for LEO and MEO missions. [8] Some of the reasons why assured access to space is a priority for the United States are stated in National Presidential Directive Number 40, which reads: Access to space through U.S. space transportation capabilities is essential to: The United States, therefore, must maintain robust, responsive, and resilient U.S. space transportation capabilities to assure access to space. for GPS III Launch Services . The USAF began the EELV program in 1994, following many years of government-funded studies into improved systems and architecture. [20], The USAF signed a contract at that time with SpaceX for two launches in 2014 and 2015 to serve as proving flights to support the certification process for the Falcon 9 v1.1 and Falcon Heavy. In 1998, when it appeared the growth in the commercial satellite industry would be able to sustain two providers of launch services, the Air Force decided to award contracts to both Boeing and Lockheed Martin for their respective launch capabilities. Making space accessible. ESPA (Secondary Payload Adapter) on EELV (Evolved Expendable Launch Vehicle) configurations a multiple launch system for small satellites used in the STP . This could include full development of a new launch system or modifications to an existing launch system, including launch infrastructure. The payload interface at each port has been standardized, allowing for hosted and separable payload interchangeability, late payload integration and manifest changes. Unlike earlier efforts to develop a new generation of space launch vehicles from a "clean sheet of paper," the EELV concept intended to capitalize on proven hardware found in the then current generation of DELTA II, ATLAS II/CENTAUR, and TITAN IV vehicles.

These launch vehicles provide critical spacelift capability to support Department of Defense and other National Security missions (together known as National Security Space (NSS) missions). 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. << /Length 5 0 R /Filter /FlateDecode >> 0000001361 00000 n

The Medium & Medium-Plus vehicles use a single Common Booster Core (CBC), while the Heavy variant uses three CBCs. [35], A three-digit (XYZ) naming convention is used for the Atlas V configuration identification. >> Up to five Aerojet Rocketdyne Graphite-Epoxy Motor solid rocket boosters can be added to increase vehicle performance, and two diameters of payload fairing are available. 0000058694 00000 n
The Delta IV Medium, Medium-Plus and Heavy configurations are evolved from flight proven Delta II and Delta III systems while incorporating the latest technology into a family of vehicles maximizing the use of common hardware.

Delta IV CBCs and DCSSs are integrated horizontally before being transported to the launchpad. Boeing developed the Delta IV based around Common Booster Cores and the Delta Cryogenic Second Stage, while Lockheed Martin developed the Atlas V based around Common Core Boosters and the Centaur upper stage.
