RD-218
Part of RD-215 Family
Glushko Nitric acid/UDMH rocket engine. R-16 stage 1. Consisted of three RD-217; had 6 combustion chambers and 3 turbines; powered the R-16 ICBM. First flight 1960.

AKA: 11D69; 8D712. Date: 1958-61. Number: 212 . Thrust: 2,592.00 kN (582,704 lbf). Unfuelled mass: 1,960 kg (4,320 lb). Specific impulse: 289 s. Specific impulse sea level: 246 s. Burn time: 90 s. Height: 2.19 m (7.18 ft). Diameter: 2.79 m (9.15 ft).

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.
