Space Launch Complex 40 (SLC-40), sometimes referred to as "Slick Forty," is one of two launch pads located at the Integrate-Transfer-Launch Complex in Cape Canaveral Space Force Station, Florida.^[2] It initially opened as Launch Complex 40 (LC-40) and was used by the United States Air Force alongside the neighboring Space Launch Complex 41 for the Titan III program. It initially saw use by the Titan IIIC throughout the 1960s and 1970s, before getting retrofitted for the Titan 34D during the 1980s. In the 1990s, Martin Marietta and the Air Force upgraded it to launch the Commercial Titan III, but the rocket's lack of success caused the pad to be used by the Titan IV throughout the decade and into the 2000s.

Following the Titan family's retirement, the SLC-40 lease was given to SpaceX in 2007 for use by their new rocket, the Falcon 9. Since the early 2010s, the pad has transformed into a high-volume launch site for the Falcon 9, being mainly used to service the company's Starlink megaconstellation. As of June 2025, the pad has hosted over 260 Falcon 9 launches.
