In the ever-evolving landscape of energy logistics, Russia is exploring an unconventional approach that could redefine the transportation of liquefied natural gas (LNG). Imagine this: massive nuclear-powered submarines quietly carrying LNG beneath the icy waters of the Arctic, bypassing traditional shipping routes and geopolitical hurdles. This ambitious idea, proposed by Russian experts, might seem like something out of a science fiction novel, but it reflects a bold strategy to navigate a challenging economic and political environment. //

The proposed submarine model would weigh a staggering 180,000 tons and boast a draft of under 14 meters, making it capable of navigating areas that conventional LNG carriers cannot. The ability to traverse beneath the Arctic’s frozen expanse presents a tantalizing opportunity to shorten shipping times and bypass traditional chokepoints. //

The design isn’t just impressive—it’s revolutionary. Equipped with three Rhythm-200 nuclear reactors, the submarine would rely on 30 MW electric propellers, allowing it to reach speeds of 17 knots (about 31.5 km/h). At 360 meters long and 70 meters wide, the vessel’s size rivals that of the world’s largest oil tankers. More importantly, its operational capabilities would cut transit times between Arctic gas fields and Asian markets from 20 days to just 12.

This innovation isn’t solely about speed. These nuclear-powered giants could safely operate year-round, including during the harsh Arctic winter months when sea ice renders many traditional shipping lanes impassable. //

Russia’s largest LNG producer, Novatek, recently announced plans to acquire 16 ice-class LNG carriers. Yet sanctions and technological barriers have stymied progress, highlighting the difficulties of expanding Arctic shipping routes. By turning to nuclear-powered submarines, Russia hopes to sidestep these roadblocks while reinforcing its sovereignty over the Arctic.
