The construction of the "Smolensk" nuclear submarine began in 1990 at the Northern Machine-Building Plant and belongs to the third generation of Russian nuclear submarines with the type 949A (NATO calls it the "Oscar-2" class). The submarine is 154 meters long, has a displacement of 24,000 tons, a depth of up to 600 meters, an underwater speed of up to 32 knots (about 59 kilometers per hour), a crew of 107 people, and can carry 24 "Granite" cruise missiles.

The Akula-class nuclear-powered attack submarine, the Soviet model is the 971 type "Pike-B" (Russian: It is the third-generation attack nuclear submarine developed and produced by the Soviet Union, and it is also the main attack nuclear submarine of the Russian Navy. "Akula-class" is named after NATO, and the word is taken from the Russian word akula, which means shark.

And the Soviet Navy actually named the Typhoon-class nuclear submarine Akula-type nuclear submarine long ago. It should also be noted that the Soviet "Pike" (Russian: type nuclear submarine refers to the second generation of attack nuclear submarines Type 671RTM (Viktor III)

There are a total of 3 types in the Akula class, which are Akula I, Akula Improved, and Akula II. Among them, the construction of the Akula II type has been after the collapse of the Soviet Union, and it is known that 4 submarines have been built, and this type of submarine is also the last type of submarine developed by the Soviet Union. Seven Akula I were built between 1982 and 1986, while five improved versions were modified or built between 1986 and 1991.

Of course, these figures are also controversial because most of them are not official. There are also contradictions between the improved and II types of the improved type.

The Akula class still uses the double-hull structure commonly used in Soviet Russia, which makes the Akula class more capable of diving than other nuclear-powered attack submarines. The Akula-class was the quietest submarine in Soviet Russia before the Yasen-class entered service. The U.S. Navy estimates that Type I is noisier than Type 688 nuclear submarines, while Type II is slightly quieter than Type 688I.

The technology is not up to par, the performance indicators are completely whimsical, and now the money is not enough, so it has not been put into service until now to form combat effectiveness, and like many things that Mao Zi boasted, more of them still stay on the drawings.
