Along with the award of two development agreements, the total amount was more than $3 billion. [3][4], On 1 March 2019, the program name was changed from EELV to National Security Space Launch (NSSL) to better reflect the growing commercial launch market and the changing nature of launch contracts, including the potential for reusable launch vehicles. 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. 0000010105 00000 n 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.

SpaceX and ULA were the two vendors selected via the competition to supply launches to the US military in the 20222027 timeframe. [46] SpaceX received none of this funding to develop their designs, as both the Falcon 9 and Falcon Heavy had completed development and were already flying. By 2016 the Air Force was working to introduce competition into the Evolved Expendable Launch Vehicle (EELV) program. The platform is optimized for GEO missions, but is adaptable for LEO and MEO missions. Up to five solid rocket boosters can be added to augment performance. 2023 Northrop Grumman.
