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. [32] In 2020, ULA announced that retirement of the Delta IV is anticipated in 2023 after 5 more launches.
