Finnish Navy (Cold War)

The Finnish Navy c136 ships 1947-Today

The Finnish Navy in the cold war: The second armistice in 1944 and the subsequent Treaty of Paris brought problems for the Finnish Navy; a maximum of 10,000t and 4500 men were allowed, and submarines and torpedoes were forbidden. The remaining coast defence ship Vaindmdéinen was taken as ‘reparations’ by the Soviet Union, the submarines were scrapped and the MTBs deprived of their tubes and reclassified as patrol boats.


The minelayer Pohjanmaa (launched 1978)

Throughout the cold war, Finland was in a very difficult position, both geographically and politically, but managed to survive as a free nation, albeit one whose policies were strongly influenced by the need not to offend the Soviet Union. The navy received only small grants from the restricted defence budget and found it difficult to replace the losses to Soviet reparations. The fleet is principally composed of mine warfare vessels, missile boats and patrol vessels, mostly of Finnish construction. The world-famous Wartsila yard was the world’s most successful builder of icebreakers, exporting to the former Soviet Union and Sweden.

Inheritance of WW2

After the Finnish-Soviet armistice, the Finnish Navy was ordered by Soviet authorities to take part in mine clearance operations, until 1950, and this caused many casualties in the crews.
Wartime vessels startred to be replaced by a new generation of ships in the 1950s and 1960s. Neutrality obliged the country balance purchases between West and East and to produce its own ships as much as possible.
British purchases:
1x Bay-class frigate Matti Kurki (training ships)
-2x Dark-class fast patrol boats (Vasama 1 and Vasama 2)
-4x BYMS-class minesweepers
Soviet Purchases:
-2x Riga-class frigates (Hämeenmaa and Uusimaa)
-4x Osa II-class fast attack craft (Tuima-class missile boats)
Local construction:
-2x Turunmaa-class gunboats (Turunmaa and Karjala)
-4x Nuoli-class fast attack craft

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 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).

The Finnish Navy Post 1990

In 1990 the abrogation of various clauses in the Treaty of Paris left Finland free to acquire submarines and torpedo-armed vessels, but financial limitations mean that there is likely to be little construction in the short term.
In 1995 there were 1800 personnel, plus 600 Border Guards. The fleet was organised into four flotillas (gunboats (Turku), missile craft, mine warfare vessels and patrol units (all at Helsinki)), until 1993 when it was reformed into the Archipelago Fleet, based at the main naval base at Turku, and the Gulf of Finland Fleet at Helsinki. FLEET STRENGTH 1947 The coast defence ship Vaindiméinen was ceded to the Soviet Union as part of reparations and renamed Vyborg, capital of the conquered southeast province of Finland, The submarines Vetehinen, Vesthiisi, Iku-Turso, Saukko and Vestkko were all stricken, the last preserved as a museum boat at Sveaborg, outside Helsinki.

In the late 1990s, the Finnish Navy started to create a new missile squadron, “Laivue 2000” (“Squadron 2000”). It was composed initially of two Hamina-class missile boats already built at this date and four Tuuli-class hovercraft. But only one prototype hovercraft was tested at the time, and in 2003 trials showed further constructions were not desirable, the lead vessel would not enter commissioned service. The squadron was thus reinforced by two new Hamina-class missile boats and the hovercraft weapons and sensor suite was recycled on the the new Hämeenmaa-class minelayers.


Hamina-class fast attack craft Pori before modernization in an MLU program

The cable layer Putsaari and pollution control vessel Hylje were both retired in 2011, replaced by a new multipurpose ship from the Uudenkaupungin Työvene shipyard. On 8 March 2011, the Louhi was launched, a new icebreaking oil spill response vessel.
The minelayer Pohjanmaa (1979) was decommissioned in 2013, Hämeenmaa becoming flagship.
In February 2015 it was reported that fatigue cracks were found in the hulls of the refitted Rauma-class missile boats. They were announced to be placed in reserve for a possible later decommission and return to full commission at any moment, especiallt given the present conflict in Ukraine ongoing since 2022.


Jehu-class landing craft

In 2018 procurement was agreed for several IAI’s Gabriel 5 naval strike missile system, to replace current maritime anti-ship missile Saab 85M (RBS15) system arriving at the end of their useful life in 2020s. The new IAI PTO2020 Gabriel are destined to the Hamina and Pohjanmaa class ships for a planned life cycle to the 2050s. Finnish Defence Forces also planned this as a multi-branch joint strike capability since these missiles are usable against ground targets. The Finnihsh designation of PTO2020 standard for Pinta Torjunta Ohjus 2020 or Surface Strike Missile 2020.

Actual Plans

The current plan is to increase Finnish mine countermeasures capabilities, starting with replacement of the Kuha- and Kiiski-class minesweepers with three Katanpää-class mine countermeasure vessels (MCMV 2010 and MITO class).
The plan evolved in 2011 to adress the Navy’s needs for fast troop deployment. In October 2012, a 34 million euro contract was signed to procure 12 fast Jehu class transport boats, plus an option for more. The awarded company is Marine Alutech i Finland, already responsible for the Uisko and Jurmo class transport boats. The Jehu class vessels are 19-metre (62 ft) long and can carry 25 troops at 40 knots (74 km/h; 46 mph), armed with a remotely controlled turret.

In September 2015, the Finnish MoD Jussi Niinistö authorized the Finnish Navy to plan “Squadron 2020” and published an official Request for Information (RFI) to shipyards in December. Following responses, a letter of intent was awarded to Rauma Marine Constructions for four vessels to fill the “Squadron 2020” program on 14 September 2016. Design stage went on until 2018 with construction started in 2019–2024 with a projected cost of 1.2 billion euro for all four on a 35 years service, known officially known as the Pohjanmaa class.

With the integration into NATO in 2020, the next-generation surface combatant of Finland were confirmed to be larger than missile boats, better suited for international (NATO) co-operation, in pre-development stage under the project name Monitoimialus 2020 (“Multi-purpose vessel 2020”) or Laivue 2020 (“Squadron 2020”) to replace the Hämeenmaa and Pohjanmaa-class minelayers and Rauma-class missile boats at the horizon 2030, seven vessels. These new ships are corvettes, the largest, most capable warships in Finnish service ever. In fact with a displacement above 4000t it is argued thay are rather small frigates and should be classed as such. Commission is now advanced to 2028 at the earnest.

On 5 May 2021 the MoD announced the purchase of four Kewatec Work 1920 vessels (now delivered) and five additional in option so service the new corvettes under 12.8 million Euros program. An additional 17 Jurmo-class ships were ordered on 29 June 2023 as Finland ramps up its military budget at every level.

Post-1990 Finnish Fleet

The current fleet still mixes mine warfare and coastal missile fast attack ships with extra coastal defences.
-Four Hamina-class fast attack craft
-Four Rauma-class fast attack craft
-Two Hämeenmaa-class minelayers/escort ships
-Three Pansio-class minelayers (one undergoing renovation as of 2015)
-Three Katanpää-class mine countermeasure vessels
-Three Kuha-class minesweepers
-Six Kiiski-class minesweepers

Coastal Forces

The Coastal forces include coastal infantry and Marines (Coastal Jaegers) and the last coastal artillery units still operable. The latter uses a variety of fixed and towed guns as well as truck-mounted anti-ship missiles. The towed guns were phased out as obsolete. The artillery-based coastal defences are to be upgraded for the most valuable, retired for the others. The coastal infantry can deploye and operate short range Spike-ER coastal missiles, wheread at a longer range, Finland uses a battery of MTO-85M (SAAB RBS-15SF) anti-ship missiles, truck mounted.
The Coastal artillery comprised fixed point, armoured turrets armed with 130mm 53 TK guns (soviet era) with mopre modern guidance and a BOR-A 550 ground and coastal surveillance radar (GSR).


The Euro-Spike missile are operated from 2005 at the Uusimaa Brigade and the RBS-15 trucks are complemented by those with the upgraded RBS-15 Mk.3 (MTO-85M). 18 Spike ER systems are deployed with Rannikko-ohjus 2006 as launchers for coastal anti-ship use src. Range 400–8,000 m (440–8,750 yd).

130 53 TK located in Isosaari.
130 53 TK or 130 TK (“130 mm rifled, 53 length caliber, turret gun”) is a Finnish fixed, heavy artillery piece, manufactured by Tampella and produced from 1982 to 1990. The caliber is 130 mm. The 130 53 TK (130 mm TorniKanuuna or “turret-cannon”) is the main weapon of the Finnish coastal artillery. Maximum firing range with HR, Frag is 27 km and with anti-ship base bleed shells; 40 km. Initial velocity 860 m/s or more. 3 rds in 20 sec. in temporary bursts with auto-loader, 6 rpm sustained. The entire turret weight weighs 16 tonnes with a 6,818 mm barrel operated by 3 NCOs and 7 soldiers. The same guns are also carried by trucks.

152 50 Tampella (now retired, with possible reactivation in case of war).
The main coastal defence artillery system was a program started at the end of WW2 by Tampella, ordered to construct new gun barrels for venerable 152 mm 45 caliber Pattern 1892 Russian Guns still in inventiry. The treaty signed with USSR deprived the Finns of that possibility and imposed neutrality, but in early 1950s funds were available to modernize these guns with a longer barrel ported to 50 calibers, new rifling allowing to use the same ammunition with cased charges but pushed at a range of 25 kilometres (16 mi) and better muzzle brakes.

The new 152 50 T were installed on coastal batteries from 1959 with a total of 29 guns converted and in the 1960s they were protected by metal cupola and overpressurization system. The cupola was in thin metal, only protected from direct hits by its shape, able to deflect rounds, but was vulnerable to even small shrapnel. Recoil springs were also modernized, and maintenance performed, but in 1976 rthere was a program to replace them by modern 130 mm guns, and in the 1980s the 152 50 T were replaced and the last withdrawn from service by 2003.
