Built in 1967, Launch Complex 39A (LC-39A) was originally designed to accommodate the large Saturn V rockets that launched astronauts on Apollo missions to the Moon. Other historic launches have utilized LC-39A as well, including missions involving the space shuttle and Skylab. Since the 1960’s the launch pad has mainly been used to launch NASA‘s crewed spaceflight missions.
LC-39A is part of Launch Complex 39 at Kennedy Space Center, which also includes LC-39B, LC-39C, Vehicle Assembly Building (VAB), Crawlerway, Orbiter Processing Facility buildings, and Launch Control Center.
In 2014, SpaceX signed a lease agreement that granted the company a 20-year exclusive leave on LC-39A. A year later, SpaceX began making modifications to the facility to allow it to process and launch its Falcon 9 and Falcon Heavy rockets. In 2019, more substantial changes to the facility began getting worked on to accommodate SpaceX’s Starship rocket.
