# ORP Mewa (1966)

ORP Mewa is a Polish base minesweeper from the Cold War era, one of a series of 12 vessels of Projekt 206F [pl], converted between 1998 and 1999 to a minehunter of Projekt 206FM. The unit measured 58.2 meters in length, 7.97 meters in width, and had a draft of 2.14 meters, with a full displacement of 470 tons. It was armed with three double sets of 25 mm 2M-3M autocannons and depth charges, and was also adapted for transporting and deploying naval mines.
It was launched on 22 December 1966 at Stocznia Gdynia, and it was commissioned into the Polish Navy on 21 May 1967. The unit, designated with the pennant number 623, initially served in the 13th Minesweeper Division of the 9th Coastal Defense Flotilla [pl] in Hel, and after its dissolution in 2006, it was assigned to the 8th Coastal Defence Flotilla. In 1987, Pope John Paul II visited the vessel. ORP Mewa was part of NATO's standing mine countermeasure forces four times and participated in many international maneuvers and exercises, neutralizing dangerous remnants from World War II in Polish and foreign waters.
The intensively used ship was removed from the fleet list in December 2019. During its 52 years of service, it covered over 800,000 nautical miles and neutralized 131 dangerous underwater objects.

## Design and construction

Work on a new type of minesweeper began at the Central Ship Design Bureau No. 2 in Gdańsk in 1958 to replace the Projekt 253Ł [pl] minesweepers, which had been in service since 1946. Initially, the new vessels were intended to be roadstead minesweepers, capable of conducting both contact and non-contact mine clearance operations in the vicinity of naval bases and laying small minefields. These ships were to have a displacement of approximately 200 tons, a speed of 18 knots, a range of 3,000 nautical miles, and armament consisting of two 45 mm guns and four 14.5 mm heavy machine guns, with mine clearance equipment standard for the late 1950s. Simultaneously, the Navy Command issued requirements for a new base minesweeper with a displacement of 570 tons, despite ongoing preparations for the licensed production of Soviet T43-class minesweepers. Under the leadership of engineer Henryk Andrzejewski, Central Ship Design Bureau No. 2 prepared both the design for a roadstead minesweeper (designated Projekt 206) and four designs for larger base minesweepers (Projekts 250–253). After much debate, it was decided to halt work on the Projekt 250–253 base minesweepers in favor of converting the Projekt 206 vessel into a base minesweeper. In 1959, Central Ship Design Bureau No. 2 developed a modified minesweeper design with a displacement of 425 tons, powered by Italian Fiat diesel engines, as no suitable propulsion units were being produced in socialist countries. The project (designated B206F) was approved for implementation in December 1959 by the Minister of National Defense, but the final technical design was not approved by the Navy Command until 19 February 1962. The documentation costs amounted to 1.7 million PLN, the construction of the prototype (the future Orlik [pl]) cost 80 million PLN, and the cost of a serial ship was 65.5 million PLN. The unit's annual operational limit was set at 700 hours, with the structure's lifespan estimated at 20 years.
ORP Mewa was built at Stocznia Gdynia (yard number 206F/11). Military oversight of the construction was carried out by Lieutenant Commander Konstanty Cudny [pl]. The shipyard used a method of building the vessel's hull from sections joined on the slipway, a technique previously developed for the mass production of fishing trawlers. The keel of the ship was laid on 18 July 1966, and it was launched on 22 December 1966. The minesweeper was given the traditional name for Polish mine warfare vessels, taken from a bird – a seagull (mewa). The ship's godmother was the wife of a Navy officer, Irena Ciećkowska.

## Tactical and technical data

The ship was a smooth-deck, ocean-going minesweeper designed for operation in conditions of partial ice cover. The overall length was 58.2 meters, width was 7.97 meters, and draft was 2.14 meters. The side height measured 4 meters. Constructed from steel, the vessel's fully welded hull was reinforced to increase resistance to underwater explosions. It was divided into seven watertight compartments: (from the bow): I – forecastle (bosun's store, ship's equipment store, food store, chain locker, and anchor windlass), II – radar station and ammunition and electrical storage, III – living quarters and gyrocompass and artillery central room, IV – auxiliary engine room, V – main engine room with propulsion control center, VI – stern crew quarters, and VII – minesweeping equipment store, steering engine, and depth charge chutes. The lowest level of the hull housed fuel tanks, freshwater, and service water tanks, as well as the propeller shafts. On the lower level of the superstructure were the officers' cabins, mess, galley, sanitary facilities, and food storage. The upper part contained the bridge and cabins for radio, navigation, and sonar, along with a command post on the signal deck covered with a tarpaulin roof and a light three-legged mast with radio equipment antennas. The standard displacement was 426 tons, while the full displacement was 470 tons.
The ship was powered by two non-reversible, turbocharged 12-cylinder four-stroke diesel engines in a V configuration, the FIAT 2312SS, each with a maximum power of 1,324 kW (1,800 hp; the nominal power was 1,400 hp at 920 rpm), driving two controllable pitch propellers via Lohman GUB reduction gears. The maximum speed of the vessel was 18.4 knots (economical speed – 17 knots). The ship could carry 55.5 tons of fuel, providing a range of 2,000 nautical miles at a speed of 17 knots. At the stern, there were two balanced rudders, each with an area of 1.7 m², operated by an MS25 steering gear. Electrical power was supplied by four British main generators, Ruston S324M, each rated at 60 kVA (consisting of a generator and a Leyland SW400 engine with a power of 72 hp at 1,500 rpm), an auxiliary generator S322M rated at 27 kVA, and an electromagnetic minesweeping generator M50. The ship's autonomy was 12 days. It could safely operate in sea state 8, while performing minesweeping tasks in sea state 4, at speeds ranging from 0 to 12 knots.
The ship's initial artillery armament consisted of three twin 2M-3M 25 mm autocannons, with a total ammunition supply of 6,000 rounds. These were positioned with one mount forward of the superstructure along the ship's centerline and two mounts side by side on the aft superstructure. The anti-submarine warfare armament included two below-deck depth charge racks, with a total of 12 B-1 depth charges. Additionally, the ship was equipped with two deck-mounted mine rails, capable of alternately carrying 10 KB or AMD-500 mines, 16 08/39 mines, or 8 AMD-1000 mines. The crew was also armed with individual weapons, including 22 AK-47 rifles and 8 pistols, with a total ammunition stock of 17,000 rounds.
Minesweeping equipment included the MT-2 contact sweep, TEM-52M electromagnetic sweep, and BAT-2 acoustic sweep. The ship's electronic equipment included the Kremnij-2 identification friend or foe system, R-609 VHF radio communication station, R-644 HF transmitter, R-671 HF receiver, R-619 wideband receiver, ARP-50-1,2M direction finder, Tamir-11M (MG-11M) sonar, Lin-M general observation radar, and Rym-K radio navigation system. The ship was also equipped with 8 smoke candle racks, a Kurs-4 gyrocompass, UKPM-1M and UKPM-3M magnetic compasses, a NEŁ-5 echo sounder, MGŁ-25 chip log, and an infrared group navigation system called Chmiel.
The minesweeper was adapted for passive defense against nuclear and chemical threats. For this purpose, three rooms with filtration and ventilation devices were constructed, and dosimetric equipment, as well as decontamination spray pipelines, were installed on the ship. Degaussing equipment further supplemented the vessel's systems.
The ship's crew initially consisted of 49 personnel – 5 officers, 16 non-commissioned officers, and 28 sailors.

## Service
### Service as a minesweeper (1967–1998)

On 21 May 1967, ORP Mewa was commissioned into the Polish Navy at the War Port in Hel, under order no. 028/org. from the Navy Commander dated May 9 of that year. The ship, bearing the pennant number 623, joined the 13th Minesweeper Division of the 9th Coastal Defense Flotilla [pl], stationed in Hel, with its first commander being Lieutenant Marian Brzeziński. The ship's mission included searching for and destroying minefields, conducting reconnaissance and control sweeping, plotting navigational routes, and guiding ships or ship formations behind the sweepers. Together with other minesweepers, Mewa participated in almost all major exercises of Polish ships and Warsaw Pact maneuvers, often taking part in neutralizing unexploded ordnance from World War II.
From 29 to 31 August 1967, ORP Mewa, along with other ships from the 13th Minesweeper Division, took part in Warsaw Pact naval maneuvers in the Baltic Sea. Between 24 and 29 May 1968, the ship participated in exercises under the codename Neptun. From 12 to 15 March 1969, Mewa made her first foreign visit, docking in Baltiysk. In the early 1970s, ORP Mewa was part of the 4th Group of the 13th Minesweeper Division, along with Rybitwa [pl] and Czajka. From May 25 to June 6, 1970, the ship participated in exercises under the codename Reda 70. From 24 to 29 May 1971, the ship took part in the Baltic maneuvers of three Warsaw Pact fleets under the codename Neptun 71. Between 3 and 6 May 1971, the minesweeper participated in exercises under the codename Reda 71.
From 17 to 25 May 1972, the ship was involved in mine-search operations in the area designated for the construction of the Northern Port in Gdańsk. From May 30 to June 5, the ship took part in Warsaw Pact naval exercises under the codename Bałtyk 72. On June 20, the Chief of Staff of the French Armed Forces visited Mewa. From June 29 to July 4, the ship participated in the festive Sea Holiday celebrations in Szczecin.
In May 1975, ORP Mewa, Warszawa, and Pelikan [pl] made a courtesy visit to Portsmouth. In June 1975, as part of the Navy’s new system of variable hull numbering, the ship's number was changed to 653. That same month, the ship took part in exercises under the codename Posejdon-75. In mid-1976, the ship's hull number was changed again to 678. On 27 November 1976, under the command of Captain Kazimierz Mielczarczyk, Mewa won the title of the best Navy ship in its class. The ship reverted to its original pennant number (623) in mid-1978. From 4 to 26 May 1983, the minesweeper participated in major Polish Navy exercises under the codename Reda-83.
From 6 to 11 April 1987, the ship took part in the Reda 87 exercises. During Pope John Paul II's third pilgrimage to Poland, on the evening of 11 June 1987, the Pope boarded Mewa in Gdynia for a voyage to Sopot. The next day, John Paul II used Mewa twice more, sailing from Sopot to Westerplatte in the morning and then through the Green Gate. From 6 to 9 August 1987, ORP Mewa, Orlik [pl], and Wodnik [pl], under the command of Captain Kazimierz Wolan, made a visit to Helsinki. In August 1988, the ship took part in Warsaw Pact naval exercises near Baltiysk. In June 1989, the ship participated in a navigational voyage to ports in Tallinn and Riga.
In June 1992, the ship took part in the prestigious Kiel Week regatta in Kiel. Between 1989 and 1991, the minesweeper was commanded by Captain Andrzej Karweta, who later became Navy Commander with the rank of vice admiral. From 6 to 18 June 1995, the ship (along with twin minesweepers ORP Tukan, Czajka, and Flaming, the submarine Wilk, and missile ships Hutnik [pl] and Metalowiec [pl]) participated in NATO naval exercises BALTOPS '95. From 2 to 14 October 1995, the ship took part in the Belgian Navy’s mine defense exercises Sandy Coast (together with the minehunters Czajka and Rybitwa [pl] and the tanker Bałtyk). From 14 to 16 September 1996, ORP Mewa, together with mine destroyers: the Belgian Lobelia and Primula and the Dutch Zierikzee, as well as Polish minesweepers Czajka, Flaming, and Śniardwy [pl], participated in mine search and destruction operations on the sea lanes in the Gdańsk Bay.
During its long service, the ship's electronic equipment was modernized: the Lin-M radar was replaced with a newer TRN-823, the Kremnij-2 identification friend or foe was replaced with Nichrom-RR, and a second SRN-2061 radar station was added. The outdated Rym-K radionavigation system was also removed and replaced with a more modern Bras system (with the Hals receiver); British Decca Pirs-1M radionavigation receivers were also installed. In the early 1980s, the ship's anti-aircraft armament was enhanced by installing two quadruple Fasta-4M launchers for 9K32 Strela-2 anti-aircraft missiles (with a total of 16 missiles) on both sides of the funnel. Changes also affected the sweeping equipment: the MT-2 contact sweep was upgraded to the MT-2W variant (with explosive cutters), and new Polish electromagnetic sweep TEM-PE-2 and deep-water, high-speed acoustic sweep BGAT were installed.

### Conversion into a minehunter

In May 1998, Mewa was decommissioned and underwent conversion into a Projekt 206FM-class minehunter, which took place between July 1998 and April 1999. The modernization project was developed at the Polish Navy Shipyard in Gdynia and was carried out under the supervision of engineer Eugeniusz Pawłowski. Most of the ship's compartments and internal hull structure were rebuilt, now divided into 10 watertight sections. Parts of the hull were replaced, and the ship received a completely new, larger superstructure, funnel, and tripod mast. The superstructure housed, among other things, the main command post and a two-compartment diving chamber from the Szczecin-based company Aquaticus, intended for new crew members – divers.
Instead of the three 25 mm cannon mounts, a ZU-23-2MR Wróbel II missile-artillery system was installed. The two quad launchers for 9K32 Strela-2 missiles were retained, and the ship was stripped of its depth charge racks. The ship's mine rails were adapted to carry, interchangeably, 12 OS-type mines, 12 MMD-1 mines, 12 MMD-2 mines, or 6 OD-type mines. The anti-mine equipment was also upgraded, now including the MT-2W contact mine (with Bofors explosive cutters), the TEM-PE-2MA electromagnetic mine, the MTA-2 acoustic mine, and two Ukwiał underwater vehicles (designed and built at Gdańsk University of Technology).
The ship's electronic equipment was modernized as well, now consisting of the Pstrokosz command support system, the Decca Bridge Master navigation radar, the SHL-100MA sonar station, the SHL-200 Flaming B towed sonar station, the Jemiołuszka precision navigation system, and the Supraśl identification friend or foe system. Other installations included a FIN Skog electronic navigational chart set, HF and UHF fibre optic gyrocompasses by Rohde & Schwarz, a C.Plath fiber-optic gyrocompass, a STN Atlas Doppler log, and the MORS shipwide broadcast system. A set of six WNP81/9 Jastrząb decoy launchers was installed, and the worn-out Fiat engines were replaced with six-cylinder Cegielski-Sulzer 6AL25/30 diesel engines, each with a maximum power output of 1,700 hp (nominally 1,100 hp at 750 rpm). The power generators were also replaced with new units.
An environmentally important modification was the installation of a new sewage treatment plant, recovered oil and oily water tanks, and a seawater desalination unit. The new equipment increased the ship's full displacement to 507 tons and raised the crew size to 54 members. The modernization cost between 58 and 60 million PLN.

### Service as a minehunter (1999–2019)

On 14 May 1999, in the presence of the Minister of National Defense Janusz Onyszkiewicz, a ceremony took place to recommission the ship into service under the command of Commander Wiesław Puchalski.
