1 Ongoing Launch Vehicle Innovation at United Launch Alliance IEEE 2010-1020

revolutionized global space access with the introduction of their respective commercial Atlas I and Delta II rockets. 12Developed with support from the Air Force as an anchor tenant, the commercial Atlas and Delta rockets evolved from their legacy ancestors. Through continuous innovation, these early commercial vehicles evolved to the current Atlas V and Delta IV launch vehicles that provide the backbone of America’s national security and science space access. Through numerous acquisitions and mergers, both of these world class rocket families are now part of United Launch Alliance (ULA). The long history of innovation that resulted in these vehicles continues today at ULA, ensuring that the Atlas and Delta families will continue to provide reliable, cost-effective space transportation for decades to come.
