The Kaiser Marquardt Aerojet Rocketdyne company developed the R-4D attitude control thruster for NASA, which was used in the Apollo Space Program on both the Lunar Module and Command Module for navigation, docking maneuvers, landing, and attitude orientation. Upgraded versions of the R-4D are still utilized on various satellites today. The model itself is not an exact replica, but rather a scaled-down version. Reference sheets indicate that the actual length of the R-4D is approximately 55.41cm (22.8in), with a maximum diameter of about 27.94cm (11in). Users should scale their model accordingly for accurate representation. All instructions and parts can be found within the zip file provided.
