Colossal in size, state-of-the art in technology and futuristic in manufacturing, the Boeing Delta IV Heavy is about to rocket its first payload into orbit. Launch is set for this fall.
The 235-foot-tall (72 meters) heavy lifter becomes the next entry in the Delta family of launch vehicles, joining the dependable Delta II and other variants of the IV. The Delta IV has a key role in the U.S. Air Force’s Evolved Expendable Launch Vehicle program—assuring access to space for the nation’s most critical satellite payloads.
