A submarine twice the size of the world’s largest commercial passenger jet, and with a similar winged design, will soon be exploring the depths of the Arctic circle.
Russia is developing the gigantic new vessel in the hope of exploiting previously untapped natural resources and undertaking scientific research.
The Arctic Research Submarine is the creation of the Rubin Design Bureau, which was responsible for the Typhoon-class missile submarines launched by the Soviet Union in the 1980s.
The vessel will be the largest civilian submersible ever constructed and will be fuelled by a nuclear reactor.
It is designed to conduct surveys using very low frequency active sonar which can penetrate the sea floor.
It has been compared by one expert to the Airbus A380, the world’s largest passenger airliner, which is roughly half its size.
