• 
  RD-0210 Kosberg N2O4/UDMH rocket engine. Cluster of four similar engines used in second stage of Proton - one providing tank pressurization (8D412K/RD-0211) and three (8D411K/RD-0210). Staged combustion cycle. First flight 1965.
• RD-0211 Kosberg N2O4/UDMH rocket engine. Proton stage 2. Out of Production. Variant of RD-0210 providing tank pressurization. Staged combustion cycle.
• 
  RD-0212 Kosberg N2O4/UDMH rocket engine. Proton stage 3. Engine unit consisting of 1 RD-0213 main engine and 4 RD-0214 vernier/steering engines. 8D48 essentially similar to 8D411 and 8D412 and has the same combustion chamber. First flight 1967.
• RD-0213 Kosberg N2O4/UDMH rocket engine. Proton stage 3. Design 1962. Version of RD-0210. Staged combustion cycle (Oxidizer pre-burner gas routed to main chamber after driving turbine). Main engine for Proton Stage 3 in system RD-0212.
• RD-0215 Kosberg N2O4/UDMH rocket engine. Developed 1962-65 for heavy Chelomei launcher (UR-900?) stage 1. Engine unit consisting of 1 RD-0217 for tank pressurization and three RD-0216. Hardware not hot-tested.
• RD-0210-HC Kosberg LOx/Kerosene rocket engine. Design concept 1990's. Proposed variant of RD-0210 engine using LOX-kerosene instead of N2O4/UDMH as propellants.
• 
  8D43 Kosberg N2O4/UDMH rocket engine. UR-500 stage 1 original concept. Hardware. In early Proton design would be clustered with 4 x Glushko 11D43. Abandoned in favor of 6 x Glushko 11D48, but later developed into the RD-0208 and RD-0210.
