A new EELV Acquisition Strategy was approved in November 2011 which recognizes only the Atlas V and Delta IV can currently provide reliable launch services to meet NSS requirements but also seeks to take advantage of the growing potential of additional commercial space launch providers. 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. ULA stated it did not have any Atlas engines available to bid in order to submit a timely proposal. APL requirements are not addressed in the SIS but their 0000010525 00000 n 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.
