UR-500 First Design
Initial design of the UR-500 Global Rocket was a straightforward cluster of UR-200 ICBM's. This was soon abandoned in favour of a more efficient design.

While Chelomei's OKB was still preparing the UR-200 draft project, it was proposed to use this as the basis for the UR-500 heavy universal rocket, with five times the payload capacity. These initial 1961 studies consisted of 4 two-stage UR-200 rockets lashed together, the first and second stages working in parallel in clusters. A third stage would be modified from the UR-200 second stage. However analysis indicated that the payload capacity could not meet the military's requirements.

Status: Design 1962. Payload: 10,000 kg (22,000 lb). Thrust: 7,994.70 kN (1,797,280 lbf). Gross mass: 571,050 kg (1,258,940 lb). Height: 48.00 m (157.00 ft). Diameter: 3.00 m (9.80 ft). Apogee: 200 km (120 mi).

The design was in response to the military GR-2 global rocket requirement for a booster that could orbit six multiple nuclear warheads. A subscale dynamic test article of the design was preserved in the Tsniimash museum. An echo of this configuration in the final Proton design was in the upper stage engines, which were direct descendants of those on the UR-200. The payload was said to be 10,000 kg as opposed to the 12,000 kg for the selected UR-500 polyblock configuration.

LEO Payload: 10,000 kg (22,000 lb) to a 200 km orbit.
