Release date:

The Orbital Piloted Assembly and Experiment Complex (OPSEK) is a proposed space station concept by Roscosmos intended to repurpose and later replace the Russian Orbital Segment of the ISS in the future. It consists of the ISS modules Nauka, Prichal, and later the two NEM laboratories. It was abandoned in 2017 and later replaced by the ROSS concept since 2021

NOTES:

• Requires the International Space Station add-on installed first
• For the 2021 plan for the Russian successor to the ISS, see the Russian Orbital Station add-on instead
