Military Review

"Buyan" marine caliber

The protagonist of this issue of “Military Acceptance” is the small rocket ship of the 21631 project “Buyan-M”. This ship is the first in our country, created by stealth technology, and the only one in the world capable of walking in shallow waters with cruise missiles on board. By the way, the “Buyans” were the first to apply the now famous “calibers” to militant objects in Syria. Then, these launches produced a shock to NATO: before that, the West did not believe that the Russian fleet could destroy targets in the Mediterranean without leaving the coastal zone of the Caspian Sea. And now the “Military Acceptance” is being sent to where the “calibers” were first fired, - to the Caspian Sea. Of course, the film crew will also be in production, where the real exclusive will be filmed: the first for the general public, until recently, the secret model of the ship, which is being developed as a continuation of the glorious “Buyan-M” project, is a trimaran capable of carrying twice more cruise missiles.

    It’s a very successful weapon. It doesn’t belong to the category of quick-destruction weapons like mine launchers. And we are glad that Russia has such weapons. I won’t begin to write with whom these ships were laid down, or they will be shot down by frenzied ones.

      Comparison of ATS with American Independence trimaran:

      Due to the fact that the low-speed ATS propellers operate in a direct, unperturbed flow, their efficiency is 20–25% higher than the efficiency of Independence water cannons built into the hull. This circumstance, together with an increase in resistance on the economic course, leads to an increase of 30–40% in the fuel supply to ensure the cruising range and to a corresponding increase in the displacement of the Independence. Moreover, an increase in displacement leads to an additional increase in fuel supply and to a corresponding deterioration in the economic characteristics of the ship.
      The elongated hulls and the location of the lateral hulls in the stern (like the plumage of the boom) enhance the stability of the Independence on the course and significantly impair its maneuverability. This is a big drawback of a ship designed for operations in coastal waters ("littoral ship").
      Due to the long lengths of the hulls during the movement of Independence in broken ice, it will accumulate between the hulls and it will be impossible to move, especially since experience has shown that the ice moving along the hull closes the water-receiving channels of water cannons, making their operation impossible. Thus, unlike the Independence SAR, it is impossible to operate in the freezing even non-Arctic seas of Russia. This is compounded by the fact that the material of its bodies is aluminum alloy.
      The composition and location of the Independence movers are similar to a single-hull ship. Therefore, he will have a similar pre-cavitation speed (10–12 knots), and at high speeds he will have intense cavitation noise. The pre-propagation speed of the ATS is 1,5–2 times greater, covering the entire range of ordinary operational speeds up to the beginning of the forced move. Accordingly, the ATS has a unique acoustic secrecy.
      The large length of the hull structures and other masses of the Independence increases its longitudinal moment of inertia by 2–2,5 times in comparison with the SAR, in which there are masses of short outriggers, bridges and a power plant near the center of mass. Since the longitudinal moment of inertia of the masses of the ship is the energy storage of its keel pitching, and the sharp central body of the Independence does not have good germination to the wave, its pitching and seaworthiness will be worse than that of the ATS.
      This significantly worsens the ability to use the weapons of the Independence, especially its helicopters, especially since its runway is located in the aft part of the deck, unlike the ATS, in which the runway is located in the plane of its pitching center.
      The traditional design of the Independence power plant, i.e. his lack of energy modules deprives him of the unique qualities of the ATS: a modular, technologically simplified method of building and repairing a ship, the possibility of increasing its KOH and the resulting economic consequences. On this basis, the Independence architectural scheme can be considered morally obsolete, as well as traditional single-hull ships.
