Russian Navy Expects 10 Buyan-M Warships by End of 2019

Buyan-M class missile corvettes armed with Kalibr cruise missiles will join the Russian Navy by the end of 2019

MOSCOW (Sputnik) – Ten Buyan-M class missile corvettes armed with Kalibr cruise missiles will join the Russian Navy by the end of 2019, Navy Deputy Commander Rear Adm. Viktor Bursuk said Friday.

The Navy previously said that it planned to receive six such warships.

“By the end of 2019, the entire series of these ships will be built, which is about 10,” Bursuk said, speaking on the Rossiya-24 television channel.

Buyan-M is a 950-ton displacement ship that is 74 meters (243 feet) long with a top speed of 45 kph (28 mph). Among other armament elements, the vessel has eight vertical launch tubes holding 3K14 Kalibr or older missiles models. The ship can carry the Kalibr missiles that were used by Russia against Islamic State militants earlier this month.

Russia is currently conducting a $325-billion rearmament program to modernize 70-percent of its military by 2020. Source sputniknews.com

Buyan Class is a river-sea type corvette designed by Zelenodolsk Design Bureau. The design incorporates stealth features to reduce the radar cross section. The flexible open architecture of the ships allows for modifications according to the future requirements.

The ship has a length of 62m, beam of 9.6m and a draft of two metres. Buyan Class has a displacement of about 500t. Each vessel can accommodate a crew of 29 to 36.

Burevestnik manufactures two variants of 100-mm А190 Lightweight Multipurpose Naval gun: А190E and А190-01.

100-mm А190 Lightweight Multipurpose Naval Gun is a single-barrel turreted automatic gun that may be installed on ships with the displacement of 500 t and more. Upon the operator’s command the fire control module automatically turns the artillery system to standby or combat-ready position, ensures ammunition selection and feeding, gun laying and firing. As a result, the artillery system has minimum response time and high rate of fire.

А190 Naval Gun can fire HE (impact fuze) and AA (time fuze) case ammunitions.
The main advantages of А190 system:
– automatic firing mode with main and back-up control means and the capability to operate in EW battlefield environment;
– minimal dead zones when engaging various target types;
– fast reaction (2…5 sec) to counter air threats. Quick shift of fire when engaging multiple targets.

The upgraded version designated as А190-01 provides significant increase in combat effectiveness. High survivability, reliability and combat effectiveness make it possible to operate the gun in various environments day and night all year around. Source burevestnik.com

AK-306 30mm close-in weapon systems

Design of the AK-630 (A-213) gun system started in 1963.  The first prototype was made in 1964 and trials were conducted until 1966.  The trials of the complete system with radar and controls went on until 1976 when the system was accepted for service.  Production started in 1969 in Tula, with a modified AK-630M (A-213M) system accepted into service in 1979.  These systems are the main close-in defense systems on modern Russian ships.

The gun itself is a 6 barrel Gatling gun designated as AO-18.  The barrels are in a single block, having exhaust-driven joint automatics.  They are belt fed with a flat magazine in the AK-630 and a drum magazine in the AK-630M.  These weapons form a part of a complete self-defense system called A-213-Vympel-A, which includes gun, radar, optical and TV control systems.  A single MP-123 Vympel system can control two 30 mm guns or one 30 mm and one 57 mm gun.  This system can engage air targets at ranges up to 4,000 m (4,400 yards) and surface targets at ranges up to 5,000 m (5,500 yards).  The TV control system can detect MTB sized ships at the distance of 75 km (40 nm) and the fighter-size air targets at 7,000 m (7,600 yards).  This system is completely automatic and does not require human supervision although it can be directed from optical control posts in case of damage or for firing on shore targets.

The AK-306 (A-219) system was a modification of the AK-630 (A-213) system for use on light ships, like air cushion craft, ekranoplanes and small displacement motor boats.  Externally, there was no difference between AK-306 and AK-630 guns, but internally instead of using the exhaust to power the automatics, the AK-306 (A-219) used electricity.  This version also lacked radar control, being only optically guided, hence making it less of a anti-missile weapon and more of a surface-to-surface weapon.  The design started in 1974 and the system was accepted into service in 1980.  By 1986, 125 systems were in service.

Buyan Class Versions

An important feature of the ships “Tornado” type that they can equally well operate in shallow waters (their maximum draft is less than two meters) – on navigable rivers, in their mouths, in archipelagic and other “narrow” the waters and on the high seas . This is due to the fact that the IAC Project 21630 designed for operations in shallow Caspian Sea, known for its fierce storms.

The single platform ships such as “Tornado” has a total displacement of 560 tons, length – 61.45 m, width – 9.6 m diesel engines. MTU 16V4000M90, working on CODAD scheme allows to develop 26 knots full speed, and water jets provide high maneuverability and move in shallow waters, reducing noise and vibration of the chassis. The ships are widely used stealth-technology, giving it low visibility. Thus, the inclined flat surface superstructure and turret, bulwarks contribute to scattering of the reflected radar waves and reduces their intensity, ie secondary radar field of the ship. The layout of rooms and corridors contribute to the free movement of personnel on the ship without going to the upper deck. An alarm every officer and sailor can quickly take their place in combat schedule. Cruising range “Tornado” in the form of small artillery ship – 1500 miles, endurance – 10 days.

The Uran missile systems comprise 16 Kh-35 missiles – 4×4 launchers with pressurised transport-launching containers. The Uran system now serves as armament of Project 1149.8 missile equipped gun boats and other vessels. A coastal defense variant and, more recently, an antiaircraft variant were later developed on the basis of this missile.The Kh-35 missile has a normal aerodynamic design and an aluminium-alloy airframe. The missile’s power plant consists of a solid-fuel booster and a turbojet powerplant. The missile’s take-off weight is 750 kilograms, the warhead weighs 150 kilograms with a range of up to 130 kilometres.

The Kh-35U anti-ship aircraft missile (Article 78U), propelled by a turbojet engine, flies toward its target at a speed of about the 300 m/s at an extremely low altitude. Owing to its high-precision radio-altimeter, the missile can skim the sea waves at an altitude of 3-5 metres at the terminal phase of trajectory. Its guidance system combines inertial guidance for during the initial flight stage and active-radar guidance during the remaining flight stage.

The missile has a folding wing and a folding tail fin.For use by coastal or shipborne launchers the missile is equipped with a rocket starter-accelerator, a container-type launcher having room for four missiles.

3M55 Oniks/P-800 Yakhont/P-800 Bolid/SSN-X-26decd8691decf2cbc25001520981ce856

The supersonic P-800 Yakhont (Gem) is a ramjet version of P-80 Zubr [SS-N-7 Starbright]. The ship, submarine and coastal-launched Yakhont is launched from the unified ampoule-shaped transport-launching container (TLC). The container is 9 m long, is 0.71 m in diameter. The firing range reaches 300 km (162 nmi.) when flying along a combined trajectory and 120 kg (265 lb.) when following only a low-altitude trajectory. Flight speed varying over the range from M=2.0 to M=2.5 is provided by the kerosene-fueled multi-mode liquid-fuel ramjet. The P-800 Bolid is the encapsulated, submarine launched version of Yakhont. An air-launched version of the missile with the take-off weight of 2,500 kg (5,507 lb.) is also being developed. The closest American counterparts, the Tomahawk and Harpoon missiles, are subsonic; the best French antiship missile, the Exocet, has a range of only 45 miles.
