The main purpose of the project 21980 boat is to protect the fleet in ports from sabotage, for which the enemy can use divers, boats, and small aircraft. The boat carries on board a modern arsenal of means for detecting and destroying various sabotage groups. The fight against sabotage in ports does not require a large supply of fuel. Vessels with a displacement of 50-200 tons are optimally suited for this purpose. Small boats have low operating costs. The boat "rook" falls into this range. Its displacement is 138 tons. The project 12980 ship can be used both at sea and on rivers.

The boat solves the tasks of air defense to ensure the protection of small objects, is used to protect the state border, to protect government officials and during special operations. In mid-2017, about 15 vessels of project 12980 were built, and their production continues at the shipyards of the Zelenodolsk Shipbuilding Plant.

Main technical parameters

• Displacement - 138 tons;
• Hull length - 31 m;
• Width - 7.4 m;
• Draft - 1.8 m;
• Maximum travel speed - 23 knots;
• Power reserve - 200 nautical miles;
• Autonomy - 5 days;
• Crew - 8 people.

The effectiveness of the use of anti-sabotage boats is largely determined by the technical reconnaissance means available on board. The basis of reconnaissance means is the Kalmar hydroacoustic complex. The electronic systems installed on the boat, means of navigation and communications are all of domestic production. As standard, the full arsenal of reconnaissance technical means includes the following components:

• hydroacoustic station Anapa;
• search underwater complex "Kalmar";
• diving equipment, rubber boats, motors;
• radar station MR-231 "Pal";
• television complex for monitoring the surface situation MTK-201 M3.

Radar and hydroacoustic stations have computer interfaces. In addition to electronic reconnaissance, there are navigation systems similar to civilian ships: high-precision GLONASS navigation receivers, waymarking systems, echo sounders, maritime VHF radios and other equipment standard for ships. The Grachonok boat has an autonomy of up to 5 days, which, with a cruising range of 200 miles, allows it to be used on short-range sea routes. It is also very convenient for use on rivers due to its low draft (only 1.8 m).

Location of surveillance and communication equipment on the wheelhouse of the boat:

1. Television surveillance complex MTK-201 M3 (TV camera, telephoto lens with remote guidance);
2. Rotary antenna of the marine radar station MR-231 "Pal";
3. Searchlight of the surface lighting system;
4. High power horn loudspeakers;
5. Flagpoles and antennas of local marine VHF radio stations;
6. GLONASS antenna under a protective plastic dome.

A universal mast with brackets for attaching any necessary equipment is installed on the wheelhouse of the Grachonok boat. For work on rivers, VHF radio stations of the river range are installed. Shortwave (specific long antennas) and satellite communications are also provided.

Characteristics of hydroacoustic station Anapa:

• swimmer detection range in fins - up to 300 m (theoretical value);
• swimmer detection range on mechanized vehicles - more than 400 m;
• simultaneous review sector - 360 degrees;
• antenna immersion - up to 40 meters;
• modern station computer interface, target identification system and other features.

Underwater search complex Kalmar

It incorporates several sonars of various resolutions: a forward-looking sonar, a multibeam sonar, a sound velocity meter in water (data are required to determine the distance to targets), and electronic computing modules. Of the additional equipment, the complex has a navigation system with a GLONASS/GPS receiver. Target coordinates are displayed on the electronic tablet of the complex, and are also transmitted via radio modem to any other necessary equipment. The Kalmar complex was developed by TetisPro engineers specifically for anti-sabotage boats.

Marine radar station MR-231 "Pal"

The main purpose of the station is navigation, but it provides other tasks, for example, the detection of surface targets. MP-231 is widely used on ships guarding the state border. The station has low power consumption and relatively low cost compared to other marine radars of similar power. The target detection range is 10-15 km, and it depends on the height of the antenna installation. Survey period (antenna rotation speed - 20-40 rpm). The transmitter of the locator operates at a frequency of 9 GHz in a pulsed mode with a power of up to 10 kW. Transmitter antenna - slotted on a flat symmetrical panel with rotation. The receiver has access to computers and other navigation cabin equipment. The coordinates are anchored in the GLONASS channel data.

diving equipment

The Project 21980 boat is used in counter-terrorism, search and rescue operations at sea, which requires good diving equipment. The boat has standard diving kits. Their number and technical characteristics are not specified. It was noted that the boat is equipped with a specialized marine diving system developed by Tethys Pro specialists in 2011. The complex has a pressure chamber, which allows maintaining the physiological fitness of divers.

Television surveillance complex

Boats 21980 are equipped with the MTK-201 M3 surface surveillance television system. Data on the technical characteristics of this particular modification are not specified, but the closest to it is the MTK-201 ME complex. Such complexes are installed on the famous Mistral helicopter carriers. They are made on the same constructive platform and have the following characteristics:

• target detection range: surface 10-20 km (depending on the weather), air 8-15;
• detection range on the thermal imaging channel - 8-16 km;
• measurement limit of the laser rangefinder - 25 km;
• computer interface, binding to coordinates from the GLONASS/GPS receiver;
• gyroscopic stabilization of all optical devices of the complex.

Armament

• MANPADS-Igla;
• Marine pedestal machine gun mount MTPU for caliber 14.5 mm;
• Anti-sabotage hand grenade launcher DP-64;
• Anti-sabotage multi-barrel grenade launcher DP-65.

MANPADS-Igla

Four 9P39 missiles are located on the launch frame, which ensure the destruction of air targets at an altitude of up to 5000 m. The course is oncoming and overtaking. Air targets can be hit when there is no visibility in the optical range, for example, due to weather conditions or night time. The coordinates of air targets are displayed on a portable electronic tablet 1L15-1 from the MANPADS kit, they come to it from the onboard radar station of the boat, as well as from other sources, for example, from the coastal defense network.

Multi-barrel grenade launcher DP-65

The complex was originally developed as an anti-sabotage complex to protect against divers, automatic self-propelled devices, as well as some surface targets that can be used to commit sabotage. DP-65 has 10 55 mm barrels. Firing range - 50-500 m. The weight of the thrown ammunition provides a radius of destruction under water up to 16 m. The complex is induced remotely using an electronic control panel. Project 12980 ship is used for port defense. To completely eliminate errors when firing, the electronic remote control of the grenade launcher has restricted areas, sectors that are entered into the device via various communication channels.

The work of grenade jet engines is accompanied by the ejection of flame from the back of the barrel. There should be no combustible objects in the 15-meter zone, which is impossible to ensure on small-sized vessels, so another solution was applied. The DP-65 grenade launcher is installed on the site behind the cabin of the boat, lined with heat-resistant materials. For reliability, the remote control is made autonomous. Its power source does not depend on the ship's onboard network.

Marine machine gun mount MTPU

It is a 14.5 mm machine gun with a rate of fire of 450 rds / min. Operated by one person manually without remote control. Cartridges - armor-piercing, incendiary, tracer.

DP-64 hand grenade launcher

A hand-held double-barreled grenade launcher with a caliber of 55 mm was specially designed to protect ships, oil platforms and other important objects from attacks by divers. Has advanced features. In the presence of two trunks with a caliber of 55 mm and a length of 600 mm, it has a weight of 10 kg. The ship can have any position when firing. There are no restrictions on firing angles (like a permanently fixed grenade launcher) for a manual model. The power of the reactive charge allows you to throw a deep-seated grenade at 1000 m. The depth of the fuse is set before the shot using a mechanical regulator and is 0-40 m. Also, the DP-64 hand grenade launcher has signal ammunition and others for marking targets.

Anti-sabotage boats "Rook" project 21980 are designed to protect the water areas of the naval bases of the Navy of the Russian Federation. Developer - Design Bureau "Vympel", shipbuilder - Zelenodolsk plant named after A.M. Gorky. Modern equipment and high seaworthiness allow the boats to solve a wide range of tasks that are typical for ships of much larger displacement.

The first boat was laid down on the slipway of the plant on February 18, 2008, launched on April 25, 2009, and was tested both in the Volga River and in the Baltic Sea. The boat became part of the Baltic Fleet in May 2010. Two more boats of this type are currently under construction.

Basic performance characteristics:
standard displacement - 138 tons
length - 31 m
width - 7.4 m
draft - 1.85 m
power plant - 2 diesels
full speed - 23 knots
autonomy - 5 days
crew - 8 people
Armament:
- MANPADS "Igla"
- 14.5 mm machine gun
- 55-mm anti-sabotage grenade launchers DP-65A and DP-64
- there is diving equipment.

The anti-sabotage boat "Rook" is equipped with modern electronic weapons, which allows you to detect and examine underwater objects. A special component of this system is the Kalmar hydroacoustic search and survey complex (POK), developed by the engineers of Tetis Pro OJSC and intended for:

– carrying out a regular sonar search for objects in the water column (including divers with closed-circuit breathing apparatus) at a distance of up to 500 m, at a boat speed of up to 8 knots and a sea state of up to 3 points;

– survey of the bottom at a depth of up to 200 m at a boat speed of up to 8 knots and a sea state of up to 3 points;

- sonar and visual inspection of detected objects using a remote-controlled uninhabited underwater vehicle;

- marking of search operations and designation of detected objects by hydroacoustic beacons-responders with reference to geographical coordinates;

- displaying real-time data of the underwater situation, processing and saving the received data.

All these operations are possible thanks to equipment included in POK Kalmar:
— multibeam sonar;
— multibeam echo sounder;
- navigational sonar station with sonar transponder buoys;
— remote-controlled uninhabited underwater vehicle;
- complex control panel.

The Kalmar complex in this configuration was mounted on the lead boat Grachonok and passed state tests in the Baltic Fleet. Later, in order to expand the capabilities of the equipment, a number of significant changes were made by the specialists of JSC Tethys Pro.

Thus, new software was developed for processing by the hydroacoustic station the signals received by the receiving-transmitting antenna, which made it possible to significantly increase the detection range of divers in the near-surface layer. The control interface of the hydroacoustic signal processing program was changed to a more informative one, and the operator's console was also improved.

In November 2010, tests were carried out with the updated software of the sonar station (SFS). The new GLS includes two forward-looking antennas with 90 ° viewing sectors in the horizontal plane and a multi-beam echo sounder with a side-scan sonar (SSS) function.

The antennas are mounted on a lowering device that extends from the ship's hull. During the tests, the GLS was used to illuminate the underwater situation during the survey of the harbor. A survey of the bottom and the water column was carried out. When the vessel was moving at a speed of about 6 knots, objects on the bottom, anchor chains, and mooring walls were observed at distances of 70–400 m.

According to the experience of the first year of operation of the complex on a boat, in order to further improve the technical and tactical characteristics of the search and survey complex, it is planned to modernize the Kalmar system, in particular, the use of a more powerful remote-controlled uninhabited underwater vehicle.

This year, the anti-sabotage forces of the Pacific Fleet will include two "Rooks"

Recently, the first anti-sabotage boat of project 21980 "Rook" entered the Primorsky flotilla of diverse forces of the fleet. The second boat of this class is currently undergoing sea trials and will also join the fleet in the near future.
In total, the Russian Navy consists of 6 units of this boat. 4 boats are under construction.
