The arrival of the Boeing Delta IV rocket at Vandenberg Air Force Base (VAFB), Calif., puts the U.S. Air Force one step closer to launching its first West Coast Evolved Expendable Launch Vehicle (EELV) mission.

The Delta IV fairing and common booster core (CBC), which includes the Rocketdyne RS-68 main engine, was transported aboard the M/V Delta Mariner vessel from the Boeing rocket manufacturing plant in Decatur, Ala., to Space Launch Complex 6 (SLC-6) at VAFB.
