China-Russia Arctic Shipping Push Accelerates With New Ice-Class Container Ships

China’s NewNew Shipping Line and Russia’s state nuclear corporation Rosatom are advancing plans to build five large ice-class container ships aimed at making commercial shipping on the Northern Sea Route a year-round operation.

The companies are in an advanced stage of developing the project, Rosatom Arctic representative Vladimir Panov earlier this week at the Eastern Economic Forum, describing the planned Arc7 vessels as potentially “revolutionary” ships for Arctic shipping. 

The ships have been designed by Russia’s United Shipbuilding Corp. and would carry more than 4,800 twenty-foot equivalent units, making them the largest container vessels specifically designed for the Arctic.

The 255-meter ships would have a beam of 35 meters and a 46-megawatt diesel-electric power plant. Two 15-MW electric propulsion motors would drive fixed-pitch propellers.

They would be capable of independently breaking through level first-year ice up to 1.7 meters thick. Their 35-meter beam was designed to match the width of channels cut by Russia’s Project 22220 nuclear icebreakers, allowing the vessels to operate within the existing icebreaker escort system when conditions become too severe for independent navigation.

The project is the latest step in a two-year effort by Rosatom and NewNew Shipping to develop a dedicated Arctic container fleet. The companies established a joint venture, Northern Sea Route Shipping Line, in China in late 2024. By June 2025, Rosatom said the partners were still selecting a shipyard and considering government support for construction of up to five Arc7 vessels. At that point, the first ship was targeted for service no later than 2027.

The timetable has since slipped or at least remains uncertain. The Arc7 ships are still being developed and there is no indication they have entered construction.

NewNew Shipping Line is meanwhile expanding its Arctic capacity with a separate group of six 4,800-TEU vessels. According to the company, four are scheduled to enter service in October 2026 on a dedicated China-St. Petersburg route, with two more planned to enter service in June 2027. Chinese and Russian reports have described these vessels as ice-class, with one Chinese maritime report identifying them as Arc3 vessels, though exact specifications remain uncertain.

In August, the operator’s 29,000-deadweight-ton Xin Xin Hai 1 became the first Chinese container ship to reach Murmansk via the Northern Sea Route, carrying about 500 containers of automotive components from China.

NewNew Shipping Line’s expanded fleet is intended to support two Northern Sea Route voyages per month and carry cargo including components for Chinese automakers in St. Petersburg, Moscow and Russia’s Kaliningrad region. The company has set a target of moving 1.2 million tonnes of cargo through the Arctic during the 2027 summer navigation season. 

The purpose-built Arc7 container ships will eventually aim to expand the narrow summer shipping season into the fall and winter months, though attracting sufficient cargo may prove challenging. South Korea’s ongoing Arctic container ship trial secured just 737 TEU, less than half of the original target.
