The eighth Project 12700 mine defense ship (code Alexandrite), named Lev Chernavin, was laid down in St. Petersburg. The laying ceremony took place at the Sredne-Nevsky shipyard.
As previously reported, the formation of the hull of the new minesweeper began on July 10. In a hermetically mounted matrix, repeating the contours of the hull of the future ship, under the influence of negative pressure, the binder was impregnated with a binder in a special way laid layers of fiberglass. The impregnation process took about two days. The official groundbreaking ceremony was scheduled for 24 July.
The groundbreaking ceremony was attended by Deputy Commander-in-Chief of the Navy for Armaments Igor Mukhametshin, Chief Advisor to the General Director of USC Viktor Chirkov and Chief Designer of Project 12700 minesweepers Alexander Kalinin.
The new ship received the name of Lev Davydovich Chernavin - a Soviet submarine officer, Rear Admiral, who commanded submarine formations of the Northern fleet.
The new minesweeper will be the eighth ship in the line of Project 12700 Alexandrite, laid down at the Sredne-Nevsky shipyard and the last one built in the first series. Starting from the ninth, the minesweepers of this project will be built taking into account the changes made to the project during the operation of the first ships. The changes will mainly affect the automation of mine action weapons.
Minesweepers of the 12700 project are able to use the latest hydroacoustic stations located both on the ship itself and on remote-controlled and autonomous underwater vehicles, and they have an automated mine action control system. Able to use traditional and traditional weapons. The ships of the Alexandrite series have a unique hull made of monolithic fiberglass, formed by vacuum infusion.
The 12700 project was developed by the Almaz Central Marine Design Bureau for the Russian Navy. These mine defense ships have a displacement of about 890 tons, the length is 62 meters and the width of 10 meters, the crew has 44 man.
