A secret Russian drone designed for long patrols of its Arctic waters will be ready for the first phase of sea trials in 2021, a top defense research official said. The non-nuclear sub is meant to stay underwater up to 3 months. The Sarma project, which is overseen by Russia’s state-owned Foundation for Advanced Research, was first confirmed to be in the works in 2018. Little is known about the future drone, except that it has been touted as an element of security for the Northern Sea Route – the 14,000km long maritime connection between northern Europe and the Pacific along Russia’s Arctic coast. Igor Denisov, the deputy head of the foundation responsible for physical and technical research, reported that the construction of the first demonstrator for the Sarma project will start in July this year while the first sea trials of the drone are planned in the White Sea in 2021.
