If that was the case, then the Air Force will have developed a new family of launch vehicles that would be primarily used only for national security payloads, resulting in higher overhead costs to DoD, while missing an opportunity to maximize the competitive posture of US industry.

At the same time, another 14 boosters were to be procured competitively beginning in 2015, with the initial launches to be performed in 2017. 0000006428 00000 n Unlike earlier efforts to develop a new generation of space launch vehicles from a "clean sheet of paper," the EELV concept intended to capitalize on proven hardware found in the then current generation of DELTA II, ATLAS II/CENTAUR, and TITAN IV vehicles. << /Type /Page /Parent 3 0 R /Resources 6 0 R /Contents 4 0 R /MediaBox [0 0 612 792] 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. In October 2018, the USAF awarded development funding to ULA, NGIS, and Blue Origin to further the design of their rockets before a subsequent competition for award to build the launch vehicles.
