Launch complex 20 is another long standing areas of Cape Canaveral Air Force Station. Positioned as the most norther of the Titan launch complexes it was built in the late 1950s and it is still active today, though not as an active launch site.
In the early 1960s it was used to test Titan I rockets, but was upgraded in 1963 to accommodate the Titan III launch vehicle. The first Titan III flight on September 1st 1964 ended in failure but a further 3 Titan III missions were successful. The complex was deactivated in 1967, 2 years after the last Titan III launch.
In the late 1980s Launch Complex 20 was selected for the Starbird program and launched the first Starbird rocket launch on December 18th 1990. since then it saw the launches of Aries, Red Tigress, and Prospector rockets.
In the mid 1995 the launch infrastructure for these rockets was dismantled and removed from the complex making it redundant once again.
In 2000 the complex was once again re-activated and flew a total of 3 Super Loki flights in that year.
The complex is currently active and used by the Advanced Technology Development Center, part of NASA, to provide R&D for testing new spaceport infrastructure. There is an active perimeter fence around the complex preventing access other than through the main security gate. Two sets of lightning protection towers can be seen from the blockhouse gate. One protects the new launch area to the north, the other to the south.
