USSR Proton 8K82K(M)

The first Proton rocket was launched in 1965 and the launch system is still in use as of 2014, which makes it one of the most successful heavy boosters in the history of spaceflight. All Protons previously were built at the Khrunichev plant in Moscow but now OLDD are in action too.
