Retired orbital launch vehicles have been instrumental in the history of space exploration, enabling the deployment of satellites, scientific instruments, and crewed missions. Representing decades of technological progress, these systems reflect the contributions of various nations, including the United States, Soviet Union, members of the European Space Agency (ESA), China, India, and Japan. The specifications, achievements, and legacy of these vehicles illustrate the foundations upon which modern space launch technologies have been built.
