MOSCOW, April 5 (AVN) - The Krylov central R&D institute based in St. Petersburg offers a family of combat corvette-class ships, the institute director academician Valentin Panshin, told the Military News Agency on Thursday.
According to him, the ships feature the institute's know-how, a totally new shape of wave line of the hull's underwater parts. This allowed to greatly overcome water resistance and decrease the ship's main power plant capacity (by some 25 percent at a speed of 30 knots). The "relieved" power plant yielded 15-18 percent of the ship's displacement and allowed for more combat load.
The XXI-2 variant with 2,000t of displacement carried 24 universal launchers of ship-to-shore, ship-to-ship, ship-to-air, ship-to-submarine missiles (Kalibr-NKE, Yakhont, Rif-M, etc), 100 mm A-190 single barrel artillery system, two six-barrel 30 mm AK-630M close-in weapon system, two quadruple torpedo systems and a chopper. All variants feature recent developments aimed to decrease the vessel's profile against enemy radars, which ensures reduction of the mean efficiency of surface dispersion by three times.
These and many other details are given in the second issue of the Military Parade magazine, which is to be published soon.
