Delta IV Heavy

A Boeing Delta IV Heavy launch vehicle lifts off from Launch Complex 37 at Cape Canaveral Air Force Station, Florida. Originally known as the Evolved Expendable Launch Vehicle, or EELV program, the National Security Space Launch program is designed to improve our nation's access to space by making space launch vehicles more affordable and reliable. The program is replacing the existing fleet of launch systems with three families of launch vehicles, each using common components and common infrastructure. The vehicles are the Boeing Delta IV Medium and Delta IV Heavy, Lockheed Martin's Atlas V and SpaceX's Falcon 9 and Falcon Heavy. The NSSL program's operability improvements over current systems include a standard payload interface, standardized launch pads and increased off-pad processing. (U.S. Air Force photo)
