The Sredne-Nevsky Shipyard enterprise hosted a solemn ceremony of launching the newest Project 12700 Aleksandrit-class mine countermeasures ship Ivan Antonov constructed within the Russian Navy’s shipbuilding programme, on April 25, 2018.
According to Vice Admiral Viktor Bursuk, the Deputy Commander-in-Chief of the Russian Navy for Armaments, the mine countermeasures ship Ivan Antonov has a number of improved characteristics compared to the lead ship of this project.
Project 12700 mine countermeasures ships are designed to struggle against sea mines, including new so-called “smart” mines, which can be detected by ships of the Ivan Antonov class both in water and in the seabed. According to the Russian Navy High Command, the new generation mine countermeasures ships of this project will significantly enhance the potential and effectiveness of the Russian Navy Minesweeping Forces.
These ships are capable to form an anti-mine contour using the newest, highly effective hydroacoustic stations located both on the ship herself and on her remote-controlled and autonomous underwater vehicles, as well as an integrated bridge-type system, the main command post as an automated mine action control system. At the same time, the ship is also able to use the traditional sweep armament.
The ship’s displacement is 890 tons, length is 61 metres, width is 10 metres, speed at full displacement is 16.5 knots, crew is over 40 people. The ship has a high manoeuvrability due to the use of various thrusters. The ship has comfortable service conditions for her crew.
This ship has a unique, the world’s largest hull of monolithic fibreglass, formed by the method of vacuum infusion.
The advantage of the ship’s hull is its higher strength in comparison with steel hulls, which provides greater survivability of the ship when searching for mines. The service life of such a hull is greater than that of a hull made of low-magnetic steel, and the hull weight is much smaller.
