DULLES, Va. Dec. 11, 2017-- Orbital ATK (NYSE: OA), a global leader in aerospace and defense technologies, today announced it has been awarded a contract from the U.S. Air Force Space and Missiles Center (AFSMC) to build LDPE, or the Long Duration Propulsive Evolved Expendable Launch Vehicle (EELV) Secondary Payload Adapter (ESPA) space platform. 0000001182 00000 n Category A payloads fit within a 4m diameter payload envelope, category B payloads fit within a 5m diameter payload envelope, and category C payloads require an extended 5m diameter envelope. The primary goal remains 100% mission success while incentivizing cost reductions. 0000017011 00000 n 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. 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.

That includes five engines that ULA currently has in its possession, which are not limited by the sanctions, since they were fully paid for prior to the Russian invasion of Crimea. As with the Delta IV, either a 4m or 5m fairing is used to shroud the payload, and vehicles are defined by the number of solids and the size of the payload fairing. The 4m diameter DCSS was retired with the Delta IV Medium after the 22 August 2019 launch of a GPS-III satellite on a Delta IV M+(4,2) two SRBs, and a 4m diameter DCSS and payload fairing. stream The Falcon Heavy is a heavy-lift rocket developed and produced by SpaceX. 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. The Atlas V family is capable of carrying payloads of 8,900 kg (19,620 lbs) to geosynchronous transfer orbit, and can lift 16,034 kg (35,343 lbs) to low-Earth orbit.

EELVs were to reduce costs by being based on standardized fairings, liquid core vehicles, upper stages, and solid rocket boosters.

As an example, an Atlas V 551 has a 5.4m payload fairing, 5 SRBs, and 1 RL-10.[35]. The USAF began the EELV program in 1994, following many years of government-funded studies into improved systems and architecture. [13] Boeing and Lockheed Martin were each awarded US$500 million for the final phase of the bid. However, the Committee was concerned that the Department was focusing too narrowly on its national security requirements and not adequately reflecting the needs of the US commercial space launch industry. EELV was important not only to reducing the launch costs of the Department of Defense, but also to the continued world-wide competitiveness of the US commercial launch industry.
