Summary

The Delta IV series of launch vehicles was developed with U.S. government support to meet new demands for government and commercial launch services. The Delta IV uses liquid hydrogen and liquid oxygen for both stages and the RS-68A for the first-stage engine and the RL10B-2 for the second stage-engine. The Delta IV Medium family of vehicles was retired in August of 2019, leaving only the Heavy configuration remaining.
