The decade of the 2020s will see only the Delta IV Heavy remain in operation following the retirement of the Delta II in 2018 and single-stick (non-Heavy) variants of the Delta IV in 2019. This will mark the final decade for the Thor-Delta rocket family as ULA's upcoming Vulcan Centaur rocket is set to replace the Delta IV Heavy in the mid-2020s.
