Russia is launching new Ivan Antonov minesweeper of Project 12700 on April 25 in St. Petersburg.
Project 12700 designates the construction of large vessels, the hulls of which are made entirely of fiberglass. Sea mines very often react to metal objects. Therefore, minesweepers had to be made either of wood, which was not very practical, or steel. Steel hulls had to be demagnetised to make vessels invisible to mine detonators, Vesti.ru reports.
Fiberglass lacks such drawbacks. Russian engineers also developed a unique vacuum infusion technology which makes it possible to use composite materials in ship-building.
At the same time, minesweepers need to be able to detect mines. The new Ivan Antonov vessel comes equipped with state-of-the-art hydroacoustic systems. The systems have been installed both on the vessel itself and on underwater robotic vehicles that the ship also carries on board.
The Ivan Antonov is armed with a light-weight six-barreled 30-millimeter gun to destroy mines floating on the water surface.
After it turned out that Deputy Prime Minister Andrei Belousov included the Fonbet betting company in the list of backbone enterprises that can count on state support, everyone started talking about these bookmakers.
