The RD-218 powered the R-16 ICBM that was referred to by Khrushchev at the UN when he claimed the USSR was producing missiles like sausages. Both the engines and the R-16 were built at Dnepropetrovsk in the Ukraine. The missile was in service until the 1970s. Diameter is per chamber. An earlier version of the engine used in the R-16 had a vacuum thrust of 255,400 kgf.
