Prichal, also known as the Uzlovoy module, is a planned future addition to either the Russian segment of the International Space Station, or a future independent Russian station. Though its volume is quite small, it adds 4 additional radial docking ports, necessary to add new modules or support more visiting vehicles. It is based on tooling and technologies shared with the NEM platform, which will be the basis of all new Russian modules for the forseeable future.
