The “Makeyev” design bureau located in Miass, provided the world of military technology with an absolutely unique development that has no comparison for several decades in a row. The submarine from project 605 with the 4K18 missiles was able to strike targets of the striking group of an enemy aircraft pretty accurately. The ballistic missile with liquid had such speed characteristics that even the best defense systems could not detect it. The flying almost vertically main part of the rocket, with speed measured in kilometers per second, could not be stopped. It was only possible a person to fight the consequences. But if we take into consideration that the Soviet missile could be supplied with different combat parts, it can be boldly stated, that a single hit by the 4K18 missile, launched from a submarine, could sink even the most protected enemy ship.
