The site was originally built for use by R-7A Semyorka missiles. The first launch to use the complex was an R-7A test on 21 December 1965, from Site 43/3. The first launch from 43/4 followed on 25 July 1967.
Both pads were damaged by explosions in the 1980s. At 16:01 UTC on 18 March 1980, 48 people were killed when a Vostok-2M exploded during fueling operations at Pad 4. The disaster injured dozens more, while damaging the pad so severely that it was not used again until 1984. On 18 June 1987, a Soyuz-U rocket exploded at liftoff on Pad 3. Both were rebuilt, and are in service as of 2009.
