Trial dive

The test submarine is tested for its surprise (equilibrium) in order to check the compliance of the calculated and actual loads. The first combat submarine of Russia "Dolphin" was built at the Baltic Plant in 1904. One of its designers and the first commander was the captain of the 2nd rank Mikhail Nikolaevich Beklemyshev. During the Russo-Japanese War of 1904-1905 To strengthen the fleet to Vladivostok, 13 submarines were delivered by rail, united in a separate detachment of destroyers, under the command of Lieutenant A.V. Plotto.
Unfortunately, they remembered these and other first submariners only in recent years. On March 19, 1906, a new class of ships - submarines was included in the classification of ships of the Navy. This day is celebrated in the Russian Navy as the day of the submariner. The proposed book tells the history of the development of submarines from the "hidden vessel" Efim Nikonov to modern atomic missile carriers
