Space Launch Complex 20, previously known as Launch Complex 20, is a launch facility located at the north end of ICBM Road on the Cape Canaveral Space Force Station (CCSFS). SLC-20 was one of four launch complexes, along with Launch Complexes 15, 16, and 19 that were constructed between 1957 and 1959 by the United States Air Force as part of a program of research and development of the Titan I Ballistic Missile. Over the ensuing six plus decades, the complex underwent several modifications to meet requirements for changing space missions. Today, the only remaining infrastructure of historical significance at the site is the Launch Control or the Launch Complex 20 Blockhouse. All other facilities were demolished in 2022-23 as part of a redevelopment and reuse modification at the complex.
