The Finnish Navy is one of the branches of the Finnish Defence Forces. The navy employs 2,300 people and about 4,300 conscripts 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.
The Baltic Sea campaigns were conducted by Axis and Allied naval forces in the Baltic Sea, the Gulf of Bothnia, the Gulf of Finland and the connected lakes Ladoga and Onega on the Eastern Front of World War II. After early fighting between Polish and German forces, the main combatants were the Kriegsmarine and the Soviet Navy, with Finland supporting the Germans until 1944 and the Soviets thereafter. The Swedish Navy and merchant fleet played important roles, and the British Royal Navy planned Operation Catherine for control of the Baltic Sea and its exit choke point into the North Sea.
Vesihiisi was a Finnish 500-tonne Vetehinen-class submarine that was constructed in the early 1930s. The vessel served in the Finnish Navy during the second World War. The name Vesihiisi refers to a mythological Finnish sea creature similar to a Siren.
Saukko (Pu110) was a small submarine that served in the Finnish Navy during the Second World War. It was designed not to exceed 100 tonnes, as it was planned for use in Lake Ladoga, and according to the 1920 Treaty of Tartu, no nation was allowed to use naval ships of more than 100 tonnes on the lake. The submarine could be divided into separate sections and transported by rail. The conning tower could be lifted off entirely. The engines were in the aft section and the batteries in the forward section. The name "Saukko" means European otter.
Turunmaa was a Finnish gunboat built in 1918. She served in the Finnish Navy during World War II. The ship was named after Turuma, a type of frigate designed for use in shallow waters of the archipelago and served in the Swedish Archipelago fleet in the late 18th century. The frigates had in turn been named after the region of Finland.
Karjala (ex-Filin) was a Finnish gunboat, built in 1918 at Ab Crichton shipyard in Turku. She served in the Finnish Navy during World War II. Karjala was named after the Finnic cultural region of Karelia. Like her sister ship Turunmaa, she served as cadet training vessel during peacetime and was nicknamed as Kurjala by cadets.
Motoscafo armato silurante, alternatively Motoscafo antisommergibili and commonly abbreviated as MAS, was a class of fast torpedo-armed vessels used by the Regia Marina during World War I and World War II. Originally, "MAS" referred to motobarca armata SVAN, Società Veneziana Automobili Navali.
The Hurja-class motor torpedo boats or H class was an Italian-designed class of Finnish motor torpedo boats, seeing service with the Finnish Navy during World War II. The five boats of the H class were built by Cantieri Baglietto in Genoa, Italy. The ships were converted into patrol boats in 1949, in accordance with the Paris peace treaty and their torpedo armament, forbidden by the treaty, was removed. The H class were stricken from the naval vessel register in 1963.
The name Hurja ("Wild") have been used for several vessels of the Finnish Navy:
The Jymy-class motor torpedo boats or J class was an Italian-designed and built class of motor torpedo boats, seeing service during World War II with the Royal Italian Navy and later with the Finnish Navy. The four boats of the J class were built by Cantieri Baglietto in Genoa, Italy and purchased by the Finns on 5 June 1943. Following World War II, the vessels were rearmed according to the Paris Peace Treaty of 1947, losing their torpedo capabilities and given more guns. They were removed from service in 1961.
The Isku-class motor torpedo boat was a Thornycroft type motor torpedo boat of the Finnish Navy. The vessel was constructed in 1926 by the Borgå varv, in Porvoo, Finland, and she saw service in World War II. Isku differed from the original Thornycraft design through its torpedo launching method. However, she was not a successful design and she only participated in the Winter War and during the first months of the Continuation War. She was stricken from the navy lists in 1942, due to extensive wear damage on the hull. She was moored at Suomenlinna and was scrapped after the war.
The Syöksy-class motor torpedo boats was a series of four British Thornycroft type motor torpedo boats of the Finnish Navy. The vessels were constructed in 1928 by the John Thornycroft & Co. shipyard in Woolston, UK. The vessels saw service in World War II. The Thornycroft type released its torpedoes by dropping them from rails in the aft. The ship then had to steer away from the torpedoes path, a manoeuvre that could be quite tricky in the close waters of the Gulf of Finland.
The Finnish Navy used several different types of motor torpedo boats during World War II. Four Soviet motor torpedo boats were captured and commissioned by the Finnish Navy during the World War II. One of these was of larger D-3 class while three others belonged to G-5 class.
Naval Detachment K was a Finnish military detachment—specifically, a flotilla that operated on Lake Ladoga during World War II.
Finnish Ladoga Naval Detachment was a Finnish naval unit stationed on Lake Ladoga between 1920–1940 and 1941–1944.
The Battle of Someri took place in the Gulf of Finland during World War II on 8–9 July 1942, between the Soviet Union and Finland. Starting as a modest operation to clear a Finnish observation post from a small island, it became one of the largest surface ship engagements in the Baltic theater.
The XIIª Squadriglia Squadriglia MAS was a formation of the Italian Royal Navy which served on Lake Ladoga as part of the Axis siege of Leningrad during World War II.
Louhi was a Finnish Navy minelayer. The ship was originally constructed for the Imperial Russian Navy but was taken over by the Finns during the Russian Civil War. She had originally been named Voin, but was renamed as M1 in Finnish service. In 1936 she was given the more personal name Louhi, following the procedure of all other major ships in the Finnish navy.
The Uskok class was a class of two motor torpedo boats built for the Royal Yugoslav Navy during the late 1920s. Named Uskok and Četnik, the boats were built by the Thornycroft Company based on their existing class of 17-metre-long (55 ft) Coastal Motor Boats, but were almost 1.5 metres (5 ft) longer. As their main armament they were equipped with cradles that carried two British-designed 456-millimetre (18 in) torpedoes, were fitted with hydrophones, and could carry depth charges instead of torpedoes if used in an anti-submarine role. The boats were lightly-built using mahogany, powered by two petrol engines, but lacked transverse bulkheads within the hull to mitigate leaks.
Sisu was a Finnish state-owned icebreaker. Built in 1939 at Wärtsilä Hietalahti Shipyard in Helsinki, she was one of the world's first diesel-electric icebreakers. In addition to icebreaking duties, she served as a submarine tender for the Finnish Navy during the summer months until the end of the Continuation War.
