The Submarine Cargo Vessel () is a proposed idea from the Russian Rubin Design Bureau. The idea is to utilise decommissioned SSBNs (nuclear-powered ballistic missile submarine) from the Russian Navy to carry cargo under the Arctic Ocean. The reason for this solution is that it would be considerably cheaper than designing and producing an entirely new type of submarine. The concept of Submarine Freight Transportation System (SFTS) was suggested in 1997 by Vladimir Postnikov. Present time this system is considered as a sea subsystem of Global Intelligent Transportation System.
