ULAs use of these tactics artificially created a need for relief from legislative restrictions on its ability to continue using RD-180relief that, with the DoDs active assistance, ULAs actively sought in the fiscal year 2016 omnibus appropriations bill.

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. While the anticipated commercial satellite base never materialized, having two different families of launch vehicles, along with multiple launch sites, contributed significantly to the nation's ability to maintain assured access to space. The goal was the creation of a cost-efficient and reliable family (or families) of "right size" spacelifters based on standardized fairings, liquid core vehicles, upper stages, and solid rockets.

These load factors, as shown in Table 1, represent a set of accelerations that %PDF-1.3 ESPA is designed to quasi-static acceleration load factors that were derived from the EELV Standard Interface Specification Document (SIS). [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. endobj 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. endobj Instead of setting those engines aside for national security launches, ULA rushed to assign them to non-national security launches that are unrestricted in their use of Russian engines. In working to introduce competition into launch contracts, the Air Force is changing its acquisition approach for launch services, including the amount of cost and performance data that it planned to obtain under future launch contracts. The primary goal remains 100% mission success while incentivizing cost reductions. 0000087266 00000 n Falcon Heavy has been certified for two Phase 1A reference orbits and as of 2019, "[i]t's not certified for all of our most stressing national security space orbits," Thompson said.
