This paper model is a Proton (formal designation: UR-500), an expendable launch system used for both commercial and Russian government space launches, the papercraft is created by L.Cherkashyn, and the scale is in 1:96.
The first Proton rocket was launched in 1965. Modern versions of the launch system are still in use as of 2015, making it one of the most successful heavy boosters in the history of spaceflight. All Protons are built at the Khrunichev State Research and Production Space Center plant in Moscow, transported to the Baikonur Cosmodrome, brought to the launch pad horizontally, and raised into vertical position for launch.
As with many Soviet rockets, the names of recurring payloads became associated with the Proton. The moniker "Proton" originates from a series of similarly named scientific satellites, which were among the rocket's first payloads. During the Cold War, it was designated the D-1/D-1e or SL-12/SL-13 by Western intelligence agencies.
Launch capacity to low Earth orbit is about 22.8 tonnes (50,000 lb). Geostationary transfer capacity is about 6,150 kilograms (13,560 lb). Commercial launches are marketed by International Launch Services (ILS). The rocket is intended to be retired before 2030. For further information please click here.
