Delta IV is an expendable launch system in the Delta rocket family. The rocket's main components are designed by Boeing's Defense, Space & Security division and built in the United Launch Alliance (ULA) facility in Decatur, Alabama. Final assembly is completed at the launch site by ULA. The rocket was designed to launch payloads into orbit for the United States Air Force Evolved Expendable Launch Vehicle (EELV) program and for the commercial satellite business. The Delta IV is available in five versions: Medium, Medium+ (4,2), Medium+ (5,2), Medium+ (5,4), and Heavy, to cover a range of payload size and weight. The Delta IV was primarily designed to satisfy the needs of the U.S. military.

The rocket is assembled at the Horizontal Integration Facility for launches from SLC-37B at Cape Canaveral and in a similar facility for launches from SLC-6 at Vandenberg Air Force Base.
