Buyan Class Corvette - Project 21630 Buyan class corvettes are in service with the Russian Navy. Three Buyan class corvettes were built by JSC Almaz Shipbuilding in St. Petersburg. Petersburg. The ships serve in the Caspian Flotilla of the Southern Military District.
Buyan-class corvettes can conduct maritime patrol missions within Russia's 200-mile maritime economic zone. The ship can undertake missions in shallow water and estuaries, especially for the direct delivery of troops on land.

The keel for the first corvette of the class, Astrakhan, was laid in February 2005 at the Almaz Shipyard in St. Petersburg. Petersburg. The ship was commissioned into the Russian Navy in January 2006. Volgodonsk was launched in May 2011. It was presented to the public during the International Maritime Defense Show (IMDS-2011) in St. Petersburg. Petersburg. The ship was delivered in December 2011 and inducted into the Russian Navy in June 2012.

The third and final ship of the class, Makhachkala, was laid down in March 2006 and launched in April 2012. Delivery of the ship was delayed due to delays in the installation of the 100mm gun mount. Makhachkala completed state sea trials in October 2012. The ship was handed over to the Russian Navy in December 2012. It became operational in the Caspian Flotilla in February 2013.
Project 21631 (Buyan-M) corvettes, missile variants of Project 21630, are being built at the Zelenodolsk shipyard. The new ships are expected to be equipped with missiles, artillery weapons and electronic countermeasure equipment. An export variant known as Project 21632 Tornado is also proposed.
The Buyan class is a river-sea type corvette designed by the Zelenodolsk Design Bureau. The design incorporates stealth features to minimize radar cross section. The ships flexible open architecture allows for changes according to future needs.
The length of the ship is 62m, the beam is 9.6m and the draft is two meters. The displacement of Buyan class is about 500t. Each ship can accommodate a crew of 29 to 36.

Corvettes have better sighting capabilities to navigate in stormy conditions. Buyan class corvettes operate up to sea state six and can deploy weapons up to sea state four.
The main gun mounted on the bow deck was a single A-190 100mm cannon. Close-point defense is provided by two AK-306 30mm close-in weapon systems. The ship is also equipped with the A-215 Grad-M Naval Multiple Launch Rocket System. The system can fire up to 40 122 mm rockets against shore targets.
The 100-mm А190 lightweight multipurpose naval gun is a single-barrel turreted automatic gun that can be mounted on ships with a displacement of 500 t and more. At the operator's command, the fire control module automatically turns on the artillery system in standby or combat-ready mode, ensures the selection and feeding of ammunition, loading and firing of the gun. As a result, artillery systems have minimal response time and a high rate of fire.
- automatic firing mode with primary and back-up means of control and the ability to operate in an EW battlefield environment;

The upgraded version, designated А190-01, provides a significant increase in combat effectiveness. High survivability, reliability and combat effectiveness make it possible to operate the gun in various environments throughout the year. Source burevestnik.com
Design of the AK-630 (A-213) gun system began in 1963. The first prototype was built in 1964 and tests were conducted until 1966. Tests of the complete system with radar and controls continued until 1976 when the system was accepted. for service. Production began at Tula in 1969, with the AK-630M (A-213M) system accepted into service in 1979. These systems are the primary close-in defense systems on modern Russian ships.
The gun itself is a 6 barrel Gatling gun designated AO-18. The barrel is in a single block with an exhaust-operated composite automatic. They are belted with a flat magazine in the AK-630 and a drum magazine in the AK-630M. These weapons are part of a complete self-defense system called A-213-Vympel-A, which includes a gun, radar, optical and TV control system. The MP-123 Vympel system can control two 30 mm guns or one 30 mm and one 57 mm gun. The system can engage air targets at ranges up to 4,000 meters (4,400 yards) and surface targets at ranges up to 5,000 meters (5,500 yards). The TV control system can detect MTB-sized ships at a distance of 75 km (40 nm) and fighter-sized air targets at 7,000 meters (7,600 yards). The system is fully automatic and does not require human supervision, although it can be directed from optical control posts in case of damage or firing at coastal targets. Source navweaps.com
The 122 mm A-215 "Grad-M" multiple rocket launcher system is designed to destroy manpower and shore equipment during sea landings, support its operations, and protect landing ships from attacks by enemy ships while crossing the sea. The high rate and range of fire provides effective fire support for the Marine landing party.

The upgraded A-215 "Grad-M" RSF is part of the arsenal of small artillery ships of the 21630 "Buyan" series. The flagship of the 21630 project was laid on January 30, 2004 in St. Petersburg. Petersburg at the shipyard of OAO “Almaz” and named “Astrakhan” (h/n 701). The vessel was launched on October 7, 2005 and entered service in 2006. It is planned to build 7 ships of this series at the "Almaz" shipyard by 2010 (according to other data - 10 ships in 2015).
Air defense capabilities are complemented by four-tube 3M47 Gibka naval missile launchers that fire Igla or Igla-S anti-aircraft missiles. The ship also has gun mounts for 14.5mm and 7.62mm machine guns.

The AK-630M-2 Duet is a radical upgrade of the AK-630 Close-In Weapon System (CIWS) introduced by the Soviet Union in the 1970s. The new weapon system uses a more conventional unmanned turret with twin 6-barrel 30mm guns to achieve a combined rate of fire of 10,000 rounds per minute. The new state-of-the-art fire control system enables fully automatic tracking and targeting against supersonic aircraft, rotary-wing aircraft, cruise missiles and various types of unmanned aerial vehicles (UAVs). Additionally, the AK-630M-2 gun system is capable of destroying small vessels such as fast attack craft at short range. The new turret has a magazine capacity for 4,000 rounds. The Duet gun system can engage targets at a distance of 5,000 meters or flying at an altitude of 5,000 meters. The Russian Navy has provided new gun systems to Buyan-M class gunboats and Ivan Gren landing ships.
The 14.5-mm Sea Pedestal Machine Gun Mount (MTPU) with 14.5-mm Machine Gun (KPVT) is intended for armament of combat boats and other sea and river vessels to engage waterborne, shore-based and airborne lightly armored targets. things
- to defeat waterborne and shore-based targets at a range of up to 2,000 m, as well as air targets at an altitude of up to 1,500 m and at a range of up to 2,000 m (using cartridges with armor-piercing incendiary bullets Б-32, armor-piercing incendiary tracer bullet БЗТ and incendiary instantaneous bullet МДЗ ).
The high-precision cruise missile 3M-14E is designed to engage day and night stationary (sedentary) land and sea targets in simple and complex weather conditions. Common targets for the 3M-14E missile are ground control points, weapons and fuel depots, airports and port facilities.

Integrated missile systems "Calibre" are designed to engage a wide range of targets on land, sea surface and under the sea in the event of intensive fire and enemy electronic countermeasures. All complexes have a single combat vehicle:
The presence of missiles for various purposes as part of the caliber systems, as well as the universal control system (SU) of the missile system allows you to change the range of missiles on the carriers depending on the task at hand and the specific combat situation.
Cruise missile 3M-14E (see photo) complex "Caliber-PL", "Caliber-NKE", "Caliber-M" is equipped with a solid propellant launch engine in the tail part where grating stabilizers are located. The TRDD-50B turbofan engine (“Product 37”, 37-01E) is a small-sized two-circuit turbojet of disposable application, integrated for all caliber missiles developed by the Omsk Engine Building Design Bureau (see picture). It is made by NPO Shani.
The 3M-14E rocket is equipped with an integrated guidance system. Control of the rocket in flight is completely autonomous. The onboard control system is based on the Autonomous Inertial Navigation System AB-40E (developed by the State Research Institute of Instrument Engineering). The missile control system consists of an RVE-B type radio altimeter (developed by UPKB detail) and a receiver of satellite navigation system signals (GLONASS or GPS). A radio altimeter provides a flight mode
