As of 2016, the Russian Orbital Segment of the ISS carries no CMGs of its own. However, the proposed but as yet unbuilt Science and Power Module (NEM-1) would be fitted with several externally-mounted CMGs. NEM-1 would be installed on one of the lateral ports of the small Uzlovoy Module or Nodal Module scheduled for completion and launch at some time within the 2016–25 Russian programme. Its twin NEM-2 (if completed) would later be installed symmetrically on the other lateral UM port.
