The '''Finnish Navy''' ({{langx|fi|'''Merivoimat'''}} {{IPA|fi|ˈmeriˌʋoi̯mɑt|}}, {{langx|sv|'''Marinen'''}}) is one of the branches of the [[Finnish Defence Forces]]. The [[navy]] employs 2,300 people and about 4,300 [[conscription|conscript]]s are trained each year. Finnish Navy vessels are given the [[ship prefix]] "FNS", short for "Finnish Navy ship", but this is not used in Finnish-language contexts. The Finnish Navy also includes coastal forces and [[coastal artillery]].

== Organization ==
The current Commander of the Navy is rear admiral [[Tuomas Tiilikainen]].<ref name=2023chief/> The navy is organized into the Navy Command, three Brigade-level units, and the Naval Academy. Since 1998 the navy also includes the [[Nyland Brigade]] in [[Dragsvik]], where Finnish Marines or ''[[Finnish Coastal Jaegers|Coastal Jaegers]]'' are trained. The Nyland Brigade is also the only [[Finland-Swedish|Swedish]]-language unit in the country and it carries on the traditions and battle-honours of the Nyland (Uusimaa) Regiment of the Swedish Army.

== History ==
During the Swedish era, the Finnish Gulf saw many battles between the Swedish and Russian fleets. Many of the Swedish naval bases were located in present-day Finland and many sailors came from Finland (see [[Archipelago Fleet]]).

[[Image:Naval Jack of Finland.svg|right|thumb|Finnish Naval Jack]]
During the Russian rule (1809–1917) an entirely Finnish Navy unit, named ''[[Suomen Meriekipaasi]]'' was
defending the Finnish coast, alongside the [[Baltic Fleet]] of the [[Imperial Russian Navy]]. The ''Meriekipaasi'' participated in the [[Crimean War]], albeit mostly with on-shore duties. The ''Meriekipaasi'' also manned the [[Coastal artillery|coastal batteries]] at the [[Santahamina]] Island during the [[Siege of Sveaborg]] in Helsinki.  The ships the ''Meriekipaasi'' operated included the steam frigates {{ship|Russian frigate|Rurik|1851|2}} and ''Kalevala'', named after the Finnish national epic. These ships later served in the [[Russian Pacific Fleet]].

=== Independent Finland ===
The first ships that the independent Finnish Navy obtained were a mix of obsolete vessels left behind by the Russians during the [[Finnish Civil War]] and vessels that had not been able to make [[Ice Cruise of the Baltic Fleet|the winter voyage]] to Kronstadt as the Russian Navy retreated from German forces. Thus, the Finnish Navy of the late 1910s and early 1920s consisted of a few gunboats ({{ship|Finnish gunboat|Klas Horn||2}}, {{ship|Finnish gunboat|Matti Kurki||2}}, {{ship|Finnish gunboat|Turunmaa||2}}, and {{ship|Finnish gunboat|Karjala||2}}), six [[S-class torpedo boat|S-class torpedo boats]], eight C-class torpedo boats, one minelayer ({{ship|Finnish minelayer|Louhi||2}}), several minesweepers, and five T-class minelaying boats. In addition to the warships, the Russians also left behind numerous other types of vessels.

Additionally, the Germans handed over two netlayers ({{ship|Finnish gunboat|Hämeenmaa||2}} and {{ship|Finnish gunboat|Uusimaa||2}}) to the Finnish Navy, and these two ships formed the core of the Finnish Navy until the coastal defence ships were commissioned. With the [[Treaty of Tartu (Russian–Finnish)|Treaty of Tartu]], Finland had to return some of the equipment they had operated earlier. This equipment included three S-class torpedo boats (''S3'', ''S4'' and ''S6''), the minesweepers ''Altair'', ''Mikula'', ''MP 7'', ''MP 11'', ''Ahvola'', ''T 12'', fifteen tugs, four smaller transports and 54 motorboats. Finland lost three more ships (the torpedo boats ''C1'', ''C2'' and ''C3'') in supporting the [[British campaign in the Baltic (1918–1919)|British campaign in the Baltic Sea]]. The three vessels remained in the Baltic even when winter froze over the sea, and the expanding ice damaged the vessels beyond repair, and they were all scuttled. The last remaining C-class torpedo boats were placed in reserve after this incident.

In 1927, after years of wrangling with various plans for how to modernize the navy, and partly due to the loss of the [[Finnish torpedo boat S2|torpedo boat ''S2'']] in heavy seas in October 1925, the [[Parliament of Finland]] [[Finnish naval armament program|approved a plan]] to build two [[coastal defence ship]]s (''Panssarilaiva'' in Finnish), as well as four [[submarine]]s. Motor torpedo boats were also acquired both from [[United Kingdom|Britain]], as well as from domestic sources. New minesweepers were also constructed. The training ship {{ship||Suomen Joutsen}} was also acquired.

=== World War II ===
The strength of the Finnish Navy at the beginning of [[World War II]] was limited. Some of the planned ships had not yet been constructed and wartime constraints on the economy prolonged ship building times.

The Finnish Navy operated the following vessels in the Baltic Sea:
* Two coastal defence ships ({{ship|Finnish coastal defence ship|Ilmarinen||2}} and {{ship|Finnish coastal defence ship|Väinämöinen||2}})
* Five submarines ({{ship|Finnish submarine|Vesihiisi||2}}, {{ship|Finnish submarine|Iku-Turso||2}}, {{ship|Finnish submarine|Vetehinen||2}}, {{ship|Finnish submarine|Vesikko||2}} and {{ship|Finnish submarine|Saukko||2}})
* Four gunboats ({{ship|Finnish gunboat|Turunmaa||2}}, {{ship|Finnish gunboat|Karjala||2}}, {{ship|Finnish gunboat|Uusimaa||2}} and {{ship|Finnish gunboat|Hämeenmaa||2}})
* Seven motor torpedo boats (two {{sclass|Sisu|motor torpedo boat|4}}, one {{sclass|Isku|motor torpedo boat|4}}, four {{sclass|Syöksy|motor torpedo boat|4}})
* One minelayer ({{ship|Finnish minelayer|Louhi||2}})
* Eight minesweepers (six {{sclass|Ahven|minesweeper|4}}, two {{sclass|Rautu|minesweeper|4}})
* One training ship {{ship||Suomen Joutsen}}

On Lake Ladoga, the Finns operated:
* One icebreaker (''Aallokas'')
* One gunboat (''Aunus'')
* One minelayer (''Yrjö'')
* One tug (''Vakava'')
* Two motor boats (''S 1'' and ''N. K. af Klercker'')

The navy also had several [[armed merchantmen|auxiliary warships]], [[icebreaker]]s and patrol boats from the coast guard.

==== Winter War ====
{{Main|Naval warfare in the Winter War}}
{{See also|Finnish Ladoga Naval Detachment}}
When the [[Winter War]] broke out the Finnish Navy moved to occupy the de-militarized [[Åland|Åland Islands]] and to protect merchant shipping. In the first month of the war, battles between Soviet ships and Finnish coastal batteries were fought at [[Hanko, Finland]], [[Utö, Finland|Utö]] and [[Primorsk, Leningrad Oblast|Koivisto]]. At Koivisto and Hanko, the batteries forced Soviet battleships to retire with damage. Finnish efforts to use submarines ({{ship|Finnish submarine|Vesikko||2}} and {{ship|Finnish submarine|Saukko||2}}) to sink Soviet capital ships failed. In December 1939 the ice became so thick that only the icebreakers could still move. The two coastal defence ships were moved to the harbour in [[Turku]] where they were used to strengthen the air defences of the city. They remained there for the rest of the war.

==== Continuation War ====
{{Main|Baltic Sea campaigns (1939–1945)}}
{{See also|Finnish Ladoga Naval Detachment|Naval Detachment K}}
Before the [[Continuation War]] five more torpedo boats were ordered from [[Italy]]. The base that the Soviets had acquired after the Winter War at the [[Hanko Peninsula]] divided the areas where the Finnish Navy would operate in two. This included the coastal artillery positions at [[Russarö]] and [[Osmussaar]], which guarded the minefields blocking the entrance to the Eastern [[Gulf of Finland]]. Large mine fields were laid down in cooperation with the [[Nazi Germany|German]] [[Kriegsmarine]] when the war began. The coastal defence ships bombarded the Soviet base at Hanko until the Soviets [[Battle of Hanko (1941)|evacuated Hanko]] in December 1941.<ref>{{cite book |last1=Auvinen |first1=Visa |title=Leijonalippu merellä |trans-title=Lion flag at sea |year= 1983 |publisher=Satakunnan Kirjapaino Oy |location=Pori, Finland |language=fi |isbn=951-95781-1-0}}</ref>

Between 1941 and 1945 some 69,779 mines and mine sweeping obstacles were laid in the [[Gulf of Finland]] by Finnish, Soviet and German naval forces. The Soviet Navy laid 16,179 mines and 2,441 mine sweeping obstacles, the Finnish navy 6,382 mines, and the German navy's vessels, submarines and aircraft laid some 45,000 mines, of which 3,000 were magnetic mines. The last mine sweeping season was held in 1957, but the mine danger continued for some 10 more years, and there are still hundreds of World War II-era mines in the Baltic Sea.<ref>''Rannikon Puolustaja'' 3/2006, p. 59</ref> The greatest loss of the Finnish Navy occurred on 13 September 1941 when {{ship|Finnish coastal defence ship|Ilmarinen||2}} ran into a mine and sank. 271 sailors died and only 132 were rescued. Most of the survivors later served in the Lake Onega flotilla, using old captured ships, including a steam-engined paddlewheeler.

In 1942 the main focus of the war at sea was on anti-submarine warfare. Finnish and German naval forces tried to prevent Soviet submarines from gaining access to the Baltic Sea. However, the mine barrier had proven to be insufficient to completely stop Soviet submarines activities. The Soviet subs sank 18 ships, seven of which were Finnish. 12 Soviet submarines were also sunk - three by Finnish submarines. The next step in submarine warfare was to completely block the Gulf of Finland with anti-submarine nets between [[Naissaar]] and [[Porkkala]]. This was done immediately after the ice cover melted on the sea. That barrier with its accompanying minefields effectively contained Soviet Naval vessels to the eastern part of the Gulf of Finland until the autumn of 1944, when the Soviets were able to use Finnish coastal seaways to circumvent the barrier.

In spring 1942 Finnish forces [[Battle of Suursaari|captured]] the island of [[Gogland]]. In July 1942 the Soviets made an attempt to occupy the small island of [[Sommers]] in the [[Gulf of Finland]]. The Soviets lost several smaller vessels (patrol and torpedo boats) together with 128 men. One-hundred and two Soviet soldiers were taken prisoner. During 1943 the navy received 14 new motor torpedo boats which were used to replace the old pre-war ones.

In 1944 the Soviets launched a [[Fourth strategic offensive|major offensive against Finland]], during which the navy fought in support of Finnish land forces the [[Gulf of Vyborg]]. In the end the ships were forced to pull out.
[[Image:Finnish submarines.jpg|thumb|Finnish {{sclass|Vetehinen|submarine|1}}s]]

==== Lapland War ====
{{main|Lapland War}}
{{See also|Baltic Sea campaigns (1939–1945)}}
In September 1944, the military operations against Germany started. The main focus was in the north, the [[Lapland War]], but the Germans also tried to capture [[Battle of Suursaari|Suursaari]] in an operation named ''[[Tanne Ost]]''. The attack was repulsed. During the battle, Finnish motor torpedo boats sank several German vessels.

The last action of the Finnish Navy was during the amphibious landing of troops from [[Oulu]] in [[Tornio]]. The Finnish gunboats successfully shelled German batteries, which had posed serious threat for the transport ships, while their anti-aircraft batteries defended the convoy from German air attacks. The navy also hunted German U-boats in the Baltic, laying its last mines of the war while doing this.

After the Finnish-Soviet armistice, the Finnish Navy was ordered to participate in the demanding mine clearance operation. The operation lasted until 1950. There were many casualties among the clearance crews.

===The Cold War era===
[[File:100 56 TK Kuivasaari 2009-08-02.JPG|thumb | 250px | [[100 56 TK]] in the [[Kuivasaari]] Island]]
The war time fleet was replaced in the 1950s and 1960s. Due to Finland's neutrality she tried to balance her purchases of equipment between the two blocs and also tried to produce its own vessels. A {{sclass2|Bay|frigate|1}} ([[HMS Porlock Bay (K650)|''Matti Kurki'']]) for training purposes, two {{sclass2|Dark|patrol boat|0}} fast patrol boats (''Vasama 1'' and ''Vasama 2'') and four {{sclass2|BYMS|minesweeper|1}}s were bought from the UK, two {{sclass2|Riga|frigate|1}}s ({{ship|Finnish frigate|Hämeenmaa||2}} and {{ship|Finnish frigate|Uusimaa||2}}) and four [[Osa-class missile boat|Osa II-class]] fast attack craft ({{sclass|Tuima|missile boat|1}}s) were obtained from the Soviet Union. Some of the vessels, such as two {{sclass|Turunmaa|gunboat|1}}s ({{ship|Finnish corvette|Turunmaa||2}} and {{ship|Finnish corvette|Karjala||2}}) and the [[Nuoli-class gunboat|Nuoli-class fast attack craft]] were produced domestically.

The Paris peace talks in 1947 resulted in a treaty that limited the offensive capability of the Finnish military. For the navy, this meant a limitation to a fleet of no more than 10,000&nbsp;tons and 4,500 personnel. As for the weaponry, torpedoes, submarines, mines and missiles were forbidden. The restrictions were eased in the 1960s and missiles and mines were allowed. The torpedo restriction was not either fully exercised as the Riga-class frigates were equipped with torpedoes and a number of torpedo boats were manufactured as gunboats that could quickly be converted to carry torpedoes. Torpedoes were re-introduced in 2018.

The Cold War limitations are no longer in place (they were nullified with the breakup of the Soviet Union), but the size of the navy has still remained roughly the same size (with the exception of tonnage).

=== Current status ===
In the late 1990s, the Finnish Navy was developing a new missile squadron called ''Laivue 2000'' ({{langx|en|Squadron 2000}}). At first it was supposed to consist of two ''Hamina''-class missile boats (already built at this date) and four {{sclass|Tuuli|hovercraft|0}} [[hovercraft]]. The Navy experimented with one prototype hovercraft, but announced in 2003 that the ''Tuuli'' class would not enter active operations and that no more of them would be built. Instead two new ''Hamina''-class missile boats were built, and the extra weaponry from the hovercraft were installed on the ''Hämeenmaa''-class minelayers.

Once Squadron 2000 was operational, the Navy shifted its attention to mine countermeasures with a view to replacing the old Kuha- and Kiiski-class minesweepers with three {{sclass|Katanpää|mine countermeasure vessel|1}}s, previously known as the MCMV 2010 and MITO classes.<ref>[http://www.mil.fi/paaesikunta/artikkelit/2552.dsp] {{Webarchive|url=https://web.archive.org/web/20090202044705/http://www.mil.fi/paaesikunta/artikkelit/2552.dsp|date=2009-02-02}}[http://tietokannat.mil.fi/data/1628/3 picture] {{webarchive|url=https://web.archive.org/web/20070927221359/http://tietokannat.mil.fi/data/1628/3|date=2007-09-27}}</ref>

The cable layer {{ship|Finnish cable layer|Putsaari||2}} and pollution control vessel {{ship|Finnish pollution control vessel|Hylje||2}} were replaced in 2011 by a new multipurpose vessel built by the ''[[Uudenkaupungin Työvene]]'' shipyard.<ref name="putsaari">Uudenkaupungin Sanomat: [http://www.uudenkaupunginsanomat.fi/uutiset/132179.html Kaapelialus Putsaari jää eläkkeelle ensi vuonna] {{webarchive|url=https://web.archive.org/web/20110720194149/http://www.uudenkaupunginsanomat.fi/uutiset/132179.html |date=2011-07-20 }}. 2010-05-07. {{Retrieved | access-date=2011-01-20}}</ref> A new [[icebreaker|icebreaking]] oil spill response vessel was named {{ship|Finnish pollution control vessel|Louhi||2}} on 8 March 2011.<ref name="syke2011">[http://www.ymparisto.fi/default.asp?contentid=378337&lan=fi&clan=en New oil and chemical spill response vessel was given the name Louhi] {{webarchive|url=https://web.archive.org/web/20110720195314/http://www.ymparisto.fi/default.asp?contentid=378337&lan=fi&clan=en |date=2011-07-20 }}.

The 1979-built minelayer {{ship|Finnish minelayer|Pohjanmaa||2}} was decommissioned in 2013, after which the minelayer ''[[Hämeenmaa-class minelayer|Hämeenmaa]]'' took over the role of [[flagship]] of the Finnish Navy.<ref>[https://web.archive.org/web/20130826072450/http://www.iltasanomat.fi/kotimaa/art-1288592301743.html Miinalaiva Pohjanmaa jätti hyvästinsä torstaina - katso video].

In 2018 Finnish Navy announced procurement of [[Israel_Aerospace_Industries|IAI's]] [[Gabriel_(missile)|Gabriel 5]] naval strike missile system. The system will replace the current maritime anti-ship missile [[RBS_15|85M (SAAB RBS15)]] system, which will reach the end of its life cycle in the 2020s. The new [[Gabriel_(missile)|PTO2020]] missiles will be installed on [[Hamina-class_missile_boat|Hamina-]] and [[Pohjanmaa-class_corvette|Pohjanmaa-]] class ships and vehicle platforms. The planned life cycle of the system extends to the 2050s. As the [[Finnish Defence Forces]] are building multi-branch joint strike capability and Gabriel 5 is capable of strikes to both naval and land domain, the new missile was given designation of PTO2020, (Pinta Torjunta Ohjus 2020 or Surface Strike Missile 2020) instead of old designation(Anti Ship Missile).<ref>[https://merivoimat.fi/-/merivoimille-uusi-pintatorjuntaohjusjarjestelma].

=== Future vessels ===

In October 2012, The Finnish Navy signed a 34 million euro contract for 12 fast transport boats with an option for more vessels with [[Marine Alutech]], a Finnish company that had also built the ''Uisko''- and ''Jurmo''-class transport boats. The {{convert|19|m|ft|0|adj=on}} ''Jehu'' transport boats can carry 25 troops and have a maximum speed in excess of {{convert|40|kn}}. Defensive capability is provided by a remotely controlled turret capable of providing [[fire support]] during a landing operation.<ref>[https://web.archive.org/web/20210227160809/https://www.defmin.fi/index.phtml?9_m=5204&s=8&v_5204=9569 Merivoimat tilaa nopeita kuljetusveneitä].

=== Vessels ===
====Fast attack craft====
* Four [[Hamina-class missile boat|''Hamina''-class]] fast attack craft
* Four [[Rauma-class missile boat|''Rauma''-class]] fast attack craft

====Mine warfare====
* Two [[Hämeenmaa-class minelayer|''Hämeenmaa''-class]] minelayers/escort ships
* Three [[Pansio-class minelayer|''Pansio''-class]] minelayers

=== Coastal forces ===
Coastal forces include both coastal infantry and the Marines (''Coastal Jaegers'') as well as the remnants of the coastal artillery units, which have moved from fixed and towed guns to truck-mounted and infantry-carried [[anti-ship missile]]s. The towed guns have been phased out as obsolete and all artillery-based coastal defences are to be retired in the near future.

* [[Spike-ER]] coastal missiles (infantry carried)
* MTO-85M anti-ship missiles, truck mounted ([[Saab AB|SAAB]] [[RBS-15]]SF)
* Coastal artillery with fixed turrets ([[130 53 TK]])
* [[BOR-A 550]] ground and coastal surveillance radar (GSR)

The [[Euro-Spike]] coastal missile system was taken into use in 2005 at the [[Uusimaa Brigade]] and the older truck-mounted [[RBS-15]] missiles have been complemented with new, upgraded RBS-15 Mk.3 (known as ''MTO-85M'').
