RS-68 — First U.S.-Built Heavy Lift, Liquid Booster Engine in Over 20 Years Delta IV The 21st Century Launch Solution Developed in partnership with the U.S. Air Force’s Evolved Expendable Launch Vehicle (EELV) program, the Boeing Delta IV continues to satisfy government requirements for access to space.

Delta IV offers design simplicity, manufacturing efficiency, and streamlined off-pad mission and vehicle integration, enabling rapid turnaround, near day-of-launch spacecraft access, and a 100 percent success rate for its first three launches. Delta IV was designed for producibility, resulting in a production capacity that far exceeds current and expected customer needs.
