Versions
The designers have proposed three versions of this engine:
* RD801 (
Ukrainian: ): This is the basic module with no
TVC.
* RD801 (
Ukrainian: ): This is a version which includes a
TVC by
gimbaling of the nozzle in two axis by +/- 6°.
* RD801V (
Ukrainian: ): High altitude of the rocket engine with extended nozzle.
