Launch Complex 17 Demolition – Part One

Launch Complex 17 at Cape Canaveral Air Force Station was built for the Air Force’s THOR Intermediate Range Ballistic Missile (IRBM) research and development in 1956, and it was used by the Air Force and NASA to support DELTA launch operations until 10 September 2011. According to Brigadier General Wayne Monteith, 45th Space Wing Commander, “The towers were workhorses in their day, supporting 325 launches between 1957 and 2011. For many, this launch complex bridged the Space Age from the early days to the era of large boosters.” The complex consisted of two virtually identical launch pads, Pad 17A and Pad 17B. On 12 July 2018 the two launch pads were demolished in a controlled explosion to make way for a commercial space company, Moon Express, to use the area for its own ventures. This post will look at some of the history of LC-17 while the next two will focus on the demolition.

The two pads consisted of fixed service towers next to which the rockets would be built up alongside and mobile service towers on rails that could encase the rockets to provide protection from the weather and help facilitate the prelaunch work then roll back out of the way during the launch. This image shows the two mobile service towers as seen from the adjacent Launch Complex 26 Air Force Space and Missile Museum.

According to the Museum: “Introduced in 1958, Thor Able was the first variant of the Thor Intermediate Range Ballistic Missile (IRBM) to be used as a space launch vehicle. Originally designed to support testing of military and civilian high-speed re-entry vehicles, Thor Able was modified to carry small payloads into space. Commercial Thor-based rockets were renamed Delta in 1960, so Thor Able represents the first generation of the Delta rocket family. Indeed, the modern Delta II and Delta III were direct descendants of the Thor Able.”

A view of Launch Complex 17 on 20 December 2007 shows a Delta II rocket on the pad ready to launch Global Positioning Satellite (GPS) 2R-18 into orbit. Note the mobile service towers have been rolled back away from the Delta II rocket and the fixed service structures.
