RD-0210
Chemical Automatics Design Bureau (KBKhA) RD-0210 is a single-chamber nitrogen-tetroxide/UDMH engine for the Proton second stage, deployed as a three-engine set with one RD-0211 steering engine. KBKhA reports 59.36 metric-ton-force (approximately 582.1 kN) vacuum thrust per engine and 326.5 s vacuum specific impulse. RD-0210 was created by modernizing RD-0208 for the three-stage Proton, and serial engines were produced by Voronezh Mechanical Plant.
