On 26 August 2021 Kuzey Star Shipyard (Turkey), in partnership with Nevsky Shipyard (a company of United Shipbuilding Corporation), sent the first LNG-powered ferry Marshal Rokossovsky of Project CNF19M for sea trials.

The ARC4 class LNG-powered ferry was ordered by FSUE Rosmorport to operate year-round on the Ust-Luga-Baltiysk ferry route unescorted by icebreakers, says Marine Engineering Bureau, the ship designer.

Marshal Rokossovsky, the lead ship, and General Chernyakhovsky, the second ship of the series, are the largest vessels ever built by the Turkish shipyards.

The new ships are to replace the obsolete ferries of Project CNF05, Baltiysk and Ambal, currently operating on the line.

The ship is intended for transportation of Russian standard trains (track gauge of 1,524 mm), and other ro-ro cargoes, including dangerous cargoes, up to 30 refrigerator containers.

Marshal Rokossovsky (hull no.191) is the lead ship in a series of two ferries of CNF19M design, being laid down on 17 October 2018 and launched on 21 August 2020.

The second ferry, General Chernyakhovsky (hull no.192), was laid down on 23 April 2019. The vessels measure 199.9m by 27.4m and have a deadweight of 11,057 tonnes.
