NASA calls on the Delta IV to launch heavy weather satellites into an orbit 22,300 miles above Earth. The rocket uses an engine called the RS-68 that is derived from the Space Shuttle Main Engine. It produces 758,000 pounds of thrust. Solid-fueled boosters can also be attached to the side for extra power.
Mass: 550,000 - 1,616,800 pounds
Height: 206 - 235 feet
Diameter: 16.4 feet
Delta IV is an active expendable launch system in the Delta rocket family. Delta IV uses rockets designed by Boeing's Integrated Defense Systems division and built in the United Launch Alliance (ULA) facility in Decatur, Alabama. Final assembly is completed at the launch site by ULA. The rockets were designed to launch payloads into orbit for the United States Air Force Evolved Expendable Launch Vehicle (EELV) program and commercial satellite business. Delta IV rockets are available in five versions, which are tailored to suit specific payload size and weight ranges. Delta IV was primarily designed to satisfy the needs of the U.S. military.
The rockets are 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 AFB. Delta IV launch vehicles can accommodate single or multiple payloads on the same mission. The rockets can launch payloads to polar orbits, sun-synchronous orbits, geosynchronous and geosynchronous transfer orbits (GTO), and low Earth orbit (LEO).
Note - LSP does not currently use the Delta IV other than in advisory role mission efforts.
