Versions

The designers have proposed three versions of this engine: * RD-801 (version 0) (

: ): This is the basic module with no TVC. * RD-801 (version 01) (

: ): This is a version which includes a TVC by gimbaling of the nozzle in two axis by +/- 6°. * RD-801V (

: ): High altitude of the rocket engine with extended nozzle.
