RD-0213 is the main-engine component of the KBKhA RD-0212 integrated Proton third-stage propulsion block. KBKhA documents one RD-0213 paired with one RD-0214 steering engine, identifies the block nitrogen-tetroxide/UDMH propellant pair, and publishes 59.36 tonnes-force vacuum thrust and 326.5 s vacuum specific impulse for RD-0213. This component record stores those exact per-engine values while leaving standalone current lifecycle unknown.
