The latest electric motor of the Russian submarine of the Lada class is so complete that the ship makes almost no sound when approaching the target, American journalist Caleb Larson writes in the National Interest Magazine.

(Source: Sputnik) According to the author, the Lada submarine’s hull is teardrop-shaped, aerodynamically, this helps to avoid turbulence and makes almost no noise. Hydrogen-oxygen fuel cells that generate electricity for the propellers also play an important role in enhancing the submarine’s noise-cancelling properties. Although there is a diesel generator, but like other diesel electric submarines, in the Lada class, electricity is also generated through a chemical reaction, which helps to reduce engine noise. Currently, Russia is building two types of diesel-electric submarines, class 636.3 (Varshavyanka) and class 677 (Lada). The Varshavyanka class was created on the basis of the 877 Paltus class of the former Soviet Union. The Black Sea Fleet has already received six of these ships, and by 2024, a batch of six submarines will be delivered to the Pacific Fleet. Earlier, General Director of Admiralteyskie Verf shipyard Alexander Buzakov said that the first two mass-produced diesel electric submarines of the fourth generation of the 677 Lada class will be equipped with Kalibr cruise missiles. The Kronstadt and Velikie Luki submarines, the second and third of the project 677, are scheduled to be delivered to the Russian Navy next year. The Saint Petersburg submarine – armed only with mines and mines, joined the Russian fleet in 2010. (according to The National Interest)
