Project 1124 Albatros Grisha class

The Grisha class antisubmarine ship is designed to search for and destroy enemy submarines found in coastal areas. Ships of the project were designed to find and destroy high-speed enemy submarines and warships escort convoys in the near sea zone. It has a limited sea-going capability. In 1991 the Russian navy operated over 70 Grisha class frigates, but that number had dwindled to 28 by 2004. This was due in large part to the difficulty in replacing the ship's turbines. The first series of Grishas was built from 1968-74, but successive improvements to the design led to four discrete versions, three for the navy and one sub-class for the KGB coastal patrols. Classified by the Russians as 'small anti-submarine ships', the Grishas pack a heavy anti-submarine armament into a relatively small hull. Combined with a respectable anti-aircraft armament, this makes the Grishas much more effective than the profusion of older escort vessels that were retired in the late 1980s.

The idea of ??creating the ship Project 1124 as a specialized high-speed anti-submarine small displacement ship occurred due to the advent of foreign submarines of the new generation and the need for effective measures to counter them in all sea areas, including and in the coastal areas near the naval bases and ships of the domestic fleet. The task for the development of small anti-submarine ship (IPC) pr.1124 "Albatross" was issued in 1963 to Zelenodol'sk CDB-340, which had previously developed the patrol ships (TFR) anti-submarine warfare (ASW) of the first and second generations. Preliminary design of the new ship (chief designer Yuri Nikolsky, watching from the Navy officer CRI VC Captain 2nd Rank Igor Kozlovsky) was considered in June 1964. The IPC technical project was completed in 1965.

Technically, the project was implemented in 1965 meeting all requirements of the Navy for a well-armed at that time. It was quite a specialized vehicle for high-speed search and destroy submarines off the coast with a total displacement of 900 tons. As approved in 1972, the adjusted pr.1124 total displacement of the IPC amounted to 940 tons, along with simplified geometry protruding hull parts. Full speed when operating the ship diesel engines and gas turbines exceeded 35 knots.

The hull is steel, flush-with considerable sheer at the bow and broadened, which occupies the entire width of the hull, superstructure extended fore. The ship was built in the longitudinal framing system with the size of the spacing of 500 mm and had an upper and lower deck, platform, and second bottom of the hold. Thickness of cladding in the fore and aft ends was 8 mm in the machine sections - 7 mm, and in the middle part - 6 mm. The second bottom has a thickness of 5 mm and a thickness of flooring decks and platforms main bulkhead reached 4 mm.

The volume of the double bottom, constituting almost 90% of the length of the body, is used to store fresh water and fuel. Bow and stern superstructure, internal part of the enclosure and the foundations were made of aluminum-magnesium alloys (AMG-5B) to reduce displacement. The mast presented a tower-like foremast square section and a three-legged mainmast of light alloys. The ships were installed with systems for year-round cooling and air conditioning in residential, office space and military posts, which allowed ships to maintain the premises in a normal temperature, humidity, cleanliness and air turnover. The ships are also equipped with space heating and ventilation systems, utility steam and system of fresh water.

The steering gear is two-cylinder electro-hydraulic steering apparatus of R-14 piston driven by two balancing wheel. Management rudders carried autopilot "Python-211" or manually from the steering gear compartment. Balancer streamlined rudder made from steel SXL-45 and weighed with a filler without rudder stock - 810 lbs. The weight rudder stock of forged steel was 365 kg, And the angle does not exceed the rudders - 36.5.

The "P-159M" retractable thruster propulsion and steering column is equipped with electro-hydraulic lifting (lowering) and electromechanical drives the propeller rotation and column control system UK3K, fencing wire mesh, a 50-liter tank of the hydraulic system and the special design niche with metal bars in the stern of the ship's hull. Management of the column was carried out remotely from the wheelhouse with UK3K system or backup remote control in the steering gear compartment. Provided, and emergency management steering column with a manual drive. To prevent freezing device provided for heating it with steam. Perform more than 12 inclusions thruster for an hour because of technical limitations are not recommended. The device was located in the steering gear compartment ship in the center line and was intended to keep the ship on foot, contrary to the waves.

Anchoring device consisted of two anchors Hall weighing 500 kg and two anchor chains 200-meter-long high-strength, with struts (buttresses) caliber 28 mm, chain stoppers, deck and anchor hawse, chain lockers under the platform of the forepeak. Anchors and mooring capstan-type electro-shag-12 located in the nose, provided the anchoring at a nominal depth of 50 m and etching anchor and anchor chain at a rate not less than 23 meters per minute. Management spire was made from the pilot house and the local post at the breakwater.

The power plant has a manual three-shaft, diesel-gas turbine with two diesel-diesel units (DDA) M-507A at 10,000 hp everyone who worked through the summing reverse gear on board two-bladed fixed pitch propeller (PN) with a diameter of 2.0 meters and a gas turbine (GT) M-8M capacity of 18,000 hp, which ran on the middle screw Photoshop diameter of 2.4 meters. The unit M-507A weighed up to 17 tons and equipped with two diesel engines M-504B with a capacity of 5,000 liters. s. each of gear and transmission, providing a joint and separate operation of diesel engines, reverse clutch, charging system. Diesel M-504B with a speed of 2000 rev / min., Resource until the first full bulkhead diesel at 3500 hours and a weight not exceeding 7.5 tonnes. Main gear (summing reversing gear) may serve until the first full bulkhead in 6000 hours. Gas turbine power M-8M 18,000 hp Provides the full stroke (afterburner) to 35 knots. Technical capacity turbine is 10 000 hours. Turbine start-up time from cold to idle no more than 3 minutes, and the development of full power possible in 10 minutes, including the preliminary stage of a five-minute warm-up. Full marching speed of the ship under two DDA was 22 knots at an average freely rotating shaft. Cruising speed under two diesels M-504B reaches 16 knots.

Variants

  1. IPC pr.1124 (Grisha-I class) - the basic design of small anti-submarine ship;
  2. IPC 1124-P (Grisha-II class) - in 1973, was ordered by the KGB for parts coast guard base on the basis of the IPC as a coast guard vessel (PSKR) pr.1124-P. Instead SAM "Osa-M" , a second gun mounts AK-725. Under this project was built 17 PSKR, most of whom had their own personal name. In addition, the border guards were sent several ships pr.1124 base;
  3. IPC pr.1124 (Grisha-III class) - in the serial construction, starting with the 13th Corps, in the early 70's. IPC pr.1124 outfitted with new artillery of the AK-725-MR-123, composed of 57-mm mounts AK-725 and 30-mm six-barrel gun mount AK-630 (with a range of up to 4 km), which is designed to defeat anti-ship cruise missiles in the near field of defense. Management of both plants was carried out radar MR-123 "Vympel";
  4. IPC pr.1124-K (Grisha-IV class) - the towing vehicle (IPC-5), which were tested anti-aircraft missile system "Dagger" and the new experimental anti-missile system RPK-5 "Downpour" (RBU-10000, installed in the nose instead of the RBU-6000, adopted not accepted);
  5. IPC pr.1124 IPC-M (Grisha-V class) - upgraded the IPC, developed in 1976 by Zelenodolsk Design Bureau. From the basic design features a new underkeel GAS "Platinum", the 76-mm gun mounts AK-176 (instead of 57 mm), SAM "Osa-MA" (instead of "Osa-M"), the presence of an auxiliary propulsion system under the transom ship. As a result of displacement of the ship increased by 30 tons and the speed was reduced to 3 knots. There were built 20 ships of this project, and the latter were equipped with radar-type "Fregat-MA" in connection with the termination of production of the radar, "Cut."

Sources and Methods

As with most other classes consisting of large numbers of small units, the identity and status of most individual units of the Grisha class is poorly attested. The correlation between construction sequence and current status and the names and numbers of most listed units is largely conjectural. One extremely authoritative source reports a total of 88 ships of this class were built, but other sources provide other numbers, with Russian-Ships.info suggesting 86 plus 6 export units.

Initially, the ships of the project were considered successful and construction continued until the collapse of the Soviet Union. Upon completion of construction of the IPC series pr.1124 they were a part of all four fleets of the USSR. As of 2007, www.arms-expo.ru/ repors that the Russian Navy had 5 IPC pr.1124, the rest were decommissioned in the 1990s. or transferred to the neighboring countries (IPC-44 and IPC-108 - in 1993, Lithuania and renamed F-11 "Zemaitis" and F-12 "Aukstaitis" respectively, and the IPC and IPC-52-43 - in 1997. Ukraine renamed U210 "Kherson" and U209 "Sumi"). Three IPC pr.1124 is a part of the FPS and Russia are on duty for the protection of the border on the Pacific Ocean.

Moscow publishing house "War Book" produced the album-monograph "This ship" (GS Dmitriev, SN Mashensky, S. Pankow) of the small anti-submarine ship, etc. 1124 "Albatross". The book "This ship", prepared on the basis of declassified documents, memoirs of designers, builders, sailors, and other public sources, provides information about the history, the device and combat operation of "Albatross" ships.

Much of the book - photo album (of about 1500 images) containing pictures of all 88 ships in 1124 and the prospect of modifications in various periods of service; ZPKB portraits of designers, plant managers, builders, responsible deliverers watching from the Navy, designers - makers of weapons, commanders most of the "Albatross"; pictures of many of the crews, types of fragments of ships, naval weapons, equipment, devices and systems. There is in this book a lot of information about ships of all border project 1124P and P1124 (ships Ave 1124 2nd series).

The name "This ship" is based on the statement of the ship Commander of the Navy SG Gorshkov. The book is A4 landscape in full color hardcover contains 288 pages of text and graphics on offset paper and 384 pages with photos on glossy paper. Copies of the book - only 500 copies. The cost of the book - from 1650 rubles. excluding the cost of shipping and other overhead costs.
