+480 Vladimir Nikolayevich Chelomei was an ambitious Chief Designer who was Korolev's constant competitor. His OKB-52 was formed in 1953 to develop winged rockets, and by the end of the 1950’s had produced some complex cruise missiles for the Soviet navy. Chelomei, partially through employment of Khrushchev’s son, had convinced the Soviet leader that he could meet the country’s missile and space requirements ‘faster, cheaper, better’ than Korolev or Yangel. In order to provide the resources to work on new space projects, Chelomei obtained the agreement of Khrushchev to absorb several other aerospace organisations in the military complex downsizing of 1960. By decree of the Central Committee of the USSR on 3 October 1960 Chelomei acquired the OKB-23 of Vladimir Mikhailovich Myasishchev, (which had formerly designed heavy bombers), as well as the M K Khrunichev heavy aviation factory. Both of these organisations had a very high level of technical and manufacturing expertise, and assisted Chelomei in quickly moving ahead on his new space projects.

Chelomei’s ambitious plan was the creation of a series of related 'Universal Rockets' - UR's - which would serve equally well in the missile and space launch role. The UR-100 (called by the West SS-11 Sego) was a light ICBM bought in huge numbers as a counter to America's Minuteman. The UR-200 was a heavier ICBM / space launcher. It was designed to have launched a series of military spacecraft - maneuvering nuclear warheads, anti-satellite combat spacecraft, nuclear-powered radar reconnaisance satellites, and raketoplan manned spaceplanes.

The UR-500 was designed for the role of ultimate heavy ICBM and as a launch vehicle for military space stations and manned circumlunar flights.

The final UR-500 design itself was such that the tooling could be used for construction of the UR-700, which was to launch massive manned missions to the moon or Mars. Developed during the 1960's in competition with Korolev's N1, it never reached fabrication stage. (The UR-300, UR-400, and UR-600 designations reportedly were not used).

With the ouster of Khrushchev Chelomei lost his main patron. The UR-200 was cancelled and the Yangel R-36 selected in its place. Korolev’s OKB obtained control of the manned circumlunar and space station programs. The UR-700 and raketoplan programs were cancelled. But Chelomei’s ASAT and radar reconnaisance satellites continued in development. And the UR-500 went into production as the Proton. It became Russia's heavy-duty space workhorse, launching planetary probes and geosynchronous satellites and Salyut and Mir space stations. It is still a commercial success on the international market.
