The NK-9 was a rocket engine designed and built in 1959 by the Kuznetsov Design Bureau. The NK designation was derived from the initials of chief designer Nikolay Kuznetsov. It was intended for the R-9 Desna, but lost this bid to the RD-111. It was then intended for the cruising stage of the Global Rocket 1, but that project was cancelled. The engine was developed into the NK-9V, with a higher expansion ratio, which was also cancelled. It was later developed into the NK-15 for the N1.^[2]

Please add references that meet all three of these criteria. If none exist, the subject is not yet suitable for Wikipedia.
