RD-0110R
RD0110R (14D24) is KBKhA's four-chamber liquid-oxygen/kerosene steering engine for the Soyuz-2.1v first stage. KBKhA identifies 23.5 tf (230.5 kN) sea-level thrust, 259 s sea-level specific impulse, 67.5 kgf/cm² chamber pressure, and control of pitch, yaw, and roll by gimbaling all four chambers. The engine's design project began in 2010, completed interdepartmental tests in 2013, and its first Soyuz-2.1v flight was on 28 December 2013; the record remains an engine identity rather than the vehicle installation.
