List of Thor and Delta launches (2020–2029)

From Wikipedia, the free encyclopedia
Main article: List of Thor and Delta launches

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.
