Family: UR. Country: Russia. Status: Hardware. Department of Defence Designation: SS-10. Article Number: 8K81. Manufacturer's Designation: UR-200.

On 16 March and 1 August 1961 the Central Committee and Politburo approved development of the UR-200 (8K81) universal rocket. The UR-200 was designed not only to send a thermonuclear warhead over a range of 12,000 km, but also to orbit the IS (Istrebitel Sputnik) ASAT; the US (Upravlenniye Sputnik) nuclear-powered naval intelligence satellite; and the Raketoplan combat re-entry vehicle, which would use aerodynamic horizontal and vertical manoeuvring to penetrate enemy space defences and be practically invulnerable. The UR-200 draft project was completed in July 1962. It technical characteristics would be similar to those of Korolevís R-9 and Yangelís R-16. Trial flights of the ICBM version ran from 4 November 1963 to 20 October 1964.

On October 13, 1964, Khrushchev was ousted from power. The new leadership, under Brezhnev, was adverse to all projects Khrushchev had supported. These included those of Chelomei and his OKB-52. An expert commission under M V Keldysh was directed to examine all of Chelomeiís projects and make recommendations as to which should be cancelled. Keldysh found that Yangelís R-36 universal rocket was superior to Chelomeiís UR-200. The UR-200 and Raketoplan were accordingly cancelled, while the IS and US satellites were redesigned for launch by the R-36.

UR-200 artefacts may be found at the following museums: Tsniimash has a 1:10 structural simulation model; Orevo has a complete sectioned missile; Baikonur has launch photographs. All launch vehicle data are accurate (except empty mass prorated between first and second stages).
