“The air-independent propulsion unit using hydrogen and oxygen is planned to be developed. It is a new technological direction that allows operating underwater for a long time without surfacing,” Litvinenko said.
Deputy Head for Physical and Technical Research of the Advanced Research Foundation Viktor Litvinenko added:
“The preliminary design has been developed. There are necessary conditions for the development of the AIP system. A hydrogen air-independent propulsion unit that could work for a long time underwater has not been developed by anyone. We hope for a positive outcome,”
As Litvinenko said, the first vehicle will be equipped with accumulators, the promising propulsion unit will be designed for further versions of the Sarma submersible.
A big number of associate contractors are working on the air-independent propulsion unit on order of the Advanced Research Foundation.
The Sarma unmanned undersea vehicle developed by the Lazurit Design Bureau will be able to dive to a depth of 1 km and accomplish assigned missions for three months independently. The submersible will be capable of covering a distance of more than 8,000 km. A vehicle demonstrator is planned to be made in 2022-2023.
Naval News comments:
Russia’s FPI (Advanced Research Foundation) recently revealed some details of a new uncrewed underwater vehicle (UUV) called Sarma. Although few details have emerged the associated graphic indicates a craft approximately in the Large-Displacement UUV category (LDUUV). This makes it roughly the same size as the existing Klavesin (Harpsichord) family. Read more about Sarma UUV at Covert Shores.
