[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. For example, in order to meet its projected reductions in life cycle costs, the EELV needed to capture at least 15 percent of the commercial market. As an example, an Atlas V 551 has a 5.4m payload fairing, 5 SRBs, and 1 RL-10.[35]. 97 24 Reducing the cost of launches and ensuring national access to space were the two main goals of the USAF space launch/EELV program. 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. A Standard Payload Interface bus was also proposed as a way to save money and improve efficiency. This requirement has been satisfied by the Falcon Heavy test flight in February 2018, Arabsat-6A in April 2019, and the STP-2 launch in June 2019. Along with the award of two development agreements, the total amount was more than $3 billion. The second stage is powered by the RL-10B engine.
