In the military parade on Red Square, Russia pulled out three Yars missile launchers, just to tell the United States and Western countries not to act rashly. Yars belongs to the Russian Strategic Rocket Forces, but the Russian Navy can't sit still, say that not only you have a big killer, but I also have a big killer.
The Russian Navy officially declares its own nuclear forces, which are referred to as the Bulava, a land-based intercontinental ballistic missile. When Russia was developing Yars, it also developed a sea-based missile, which was called Bulava, so the universal rate of components of Bulava and Yars missiles reached 80~90%.
You can understand that Yars went to sea, or it was the development of a bomb for two purposes. Yars demonstrated its nuclear power on land, while the Bulava demonstrated its presence at sea, on the Boreas' strategic missile submarines.
Before the Bulava was installed, the SLBMs that Russia possessed were liquid rocket propellants. "Light boat" and "Deep Blue" are actually liquid rocket propellants. The Bulava is the first solid rocket-propellant submarine-launched missile in the history of Russia or the Soviet Union, and its reliability and safety are higher, the fast reaction capability is stronger, and the sustainable work ability in the submarine is stronger.
The Russian Navy's announcement of Rava is to tell the United States that a number of "Boreas" strategic missile nuclear submarines have all been equipped with this missile, and that it is necessary to take into account Russia's powerful nuclear forces at sea. It is to say to the United States and NATO, don't act rashly!
