Evolved Expendable Launch Vehicle (EELV)

The Evolved Expendable Launch Vehicle (EELV) is a family of reliable rockets designed to deliver satellites and space payloads into orbit for the U.S. military and other government agencies. Developed to be cost-effective and versatile, EELVs replace older launch systems, offering improved performance and lower costs through advanced technology and competition. Notable models include Atlas V and Delta IV. These rockets are "expendable," meaning they are used once and then discarded. EELVs play a crucial role in maintaining national security, space infrastructure, and scientific missions by providing regular, dependable access to space.
