Rautu-class Minesweeper
''Rautu'' and ''Vilppula'' were Kljuz class Minesweepers left by the Soviets to Finland in 1918 since they would not have survived the harsh sailing to the Leningrad. Ships had weak hulls and their engines were not particularly powerful. During peacetime they were used as depot and test ships. ''Vilppula'' was designated as ''T-2'' and ''Zashtshitnik'' and ''Rautu'' as ''Murman'' before they were included to the Finnish Navy In war time the ships were used as minesweepers but occasionally were assigned with more exotic tasks. On 5 December 1941 after Soviets had fled from Hanko there was urgent and pressing need to clear inshore seaways for merchants however the weak hulled minesweepers could not operate in the prevailing conditions. ''Rautu'' and ''Louhi'' were used as icebreakers breaking clearing the waters for the smaller minesweepers to operate. On 25 July 1944 ''Vilppula'' and small Finnish coastal minesweeper ''Merkurius'' (former customs boat of ~20 tons in displacement) ...

Finnish Navy
The Finnish Navy ( fi, Merivoimat, sv, Marinen) 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. Organization The current Commander of the Navy is rear admiral Jori Harju. 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 '' Coastal Jaegers'' are trained. Nyland Brigade is also the only Swedish language unit in the country and it carries on the traditions and battle-honours of the Nyland (Uusimaa) Regiment of the Swedish Army.

Minesweeper (ship)
A minesweeper is a small warship designed to remove or detonate naval mines. Using various mechanisms intended to counter the threat posed by naval mines, minesweepers keep waterways clear for safe shipping. History The earliest known usage of the naval mine dates to the Ming dynasty.Needham, Volume 5, Part 7, 203–205. Dedicated minesweepers, however, only appeared many centuries later during the Crimean War, where they were deployed by the British. The Crimean War minesweepers were rowboats trailing grapnels to snag mines. Minesweeping technology picked up in the Russo-Japanese War, using aging torpedo boats as minesweepers. In Britain, naval leaders recognized before the outbreak of World War I that the development of sea mines was a threat to the nation's shipping and began efforts to counter the threat. Sir Arthur Wilson noted the real threat of the time was blockade aided by mines and not invasion. The function of the fishing fleet's trawlers with their trawl gear was ...

75mm 50 Caliber Pattern 1892
The 75 mm 50 caliber Pattern 1892 was a Russian naval gun developed in the years before the Russo-Japanese War that armed the majority of warships of the Imperial Russian Navy during the Russo-Japanese War and World War I. The majority of ships built or refit between 1890-1922 carried Pattern 1892 guns. During its career the role of the guns evolved from one of anti-torpedo boat defense to coastal artillery and anti-aircraft use. History In 1891 a Russian naval delegation was shown three guns designed by the French designer Canet. One was a 75 mm/50 caliber gun, one a 120 mm/45 caliber gun and the last was a 152mm/45 caliber gun. All three guns used fixed QF ammunition which produced a rate of fire of 15 rpm for the 75 mm gun, 12 rpm for the 122 mm gun and 10 rpm for the 152 mm gun. The Russians were impressed and in 1892 they negotiated a production license for all three guns. Construction 75mm/50 caliber Pattern 1892 guns were produced at the Obu ...

Madsen 20 Mm Anti-aircraft Cannon
The 20 mm AA Machine Cannon M/38 was a 20 mm rapid fire autocannon produced by the Danish company Dansk Industri Syndikat (DISA). The gun, which could be adapted to several tactical uses, was a primary weapon of the military of Denmark. It was also exported to numerous countries around the world because of its versatility. The cannon was built at the DISA works in Herlev near Copenhagen. The company supplied several different types of mountings with the weapon which allowed it to be employed in a variety roles such as aerial defences, anti-tank warfare or on naval ships. Design The 20 mm Madsen Cannon was originally built by Colonel V. H. O. Madsen of the Royal Danish Army. A version with a necked-out 23 mm round was also produced for the cannon known as the 23 mm Madsen. Combat Several 20 mm machine cannons of the Danish Army were responsible for knocking out eleven armoured cars and two Panzer I's during the German invasion on April 9, 1940. A ...

Soviets
Soviet people ( rus, сове́тский наро́д, r=sovyétsky naród), or citizens of the USSR ( rus, гра́ждане СССР, grázhdanye SSSR), was an umbrella demonym for the population of the Soviet Union. Nationality policy in the Soviet Union During the history of the Soviet Union, different doctrines and practices on ethnic distinctions within the Soviet population were applied at different times. Minority national cultures were never completely abolished. Instead the Soviet definition of national cultures required them to be "socialist by content and national by form", an approach that was used to promote the official aims and values of the state. The goal was always to cement the nationalities together in a common state structure. In the 1920s and the early 1930s, the policy of national delimitation was used to demarcate separate areas of national culture and the policy of korenizatsiya (indigenisation) was used to promote federalism and strengthen non-Russian ...

Finnish Minelayer Louhi
''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 (''Miinalaiva 1'') 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 ship was designed as a minelayer but was not particularly good at it due to its slow speed, bad seakeeping qualities and inadequate storage space. During peacetime, ''Louhi'' or ''M1'' was used as depot ship with its storage rooms refitted as crew quarters. ''Louhi'' sunk on 12 January 1945, while returning from a mine laying operation. An explosion at the stern of the ship at 12:50 sank the ship in two minutes, with 11 casualties. From the Russian Navy to the Finnish Navy The minelayer ''Voin'' was built during World War I in Kolomna near Moscow, and it was deployed at the Baltic Sea. I ...

Porkkala
Porkkalanniemi ( sv, Porkala udd) is a peninsula in the Gulf of Finland, located at Kirkkonummi (Kyrkslätt) in Southern Finland. The peninsula had great strategic value, as coastal artillery based there would be able to shoot more than halfway across the Gulf of Finland. If the same power controlled the Estonian coast, on the opposite side of the gulf, it would then be able to block Saint Petersburg's naval access to the Baltic Sea. The distance to Estonia at the closest point is only . Porkkala is furthermore located only from Helsinki, the Finnish capital, and a foreign power based there would be able to exert significant pressure on the Finnish government. Nowadays, the coasts of the peninsula are popular birdwatching areas during the spring migrations of Arctic geese and other waterfowl. History At the end of the Second World War, the Soviet Union secured the rights of lease to a naval base at Porkkala, in accordance with the Moscow armistice agreement that ended ...

Douglas A-20 Havoc
The Douglas A-20 Havoc (company designation DB-7) is an American medium bomber, attack aircraft, Intruder (air combat), night intruder, night fighter, and reconnaissance aircraft of World War II. Designed to meet an Army Air Corps requirement for a bomber, it was ordered by France for their air force before the USAAC decided it would also meet their requirements. French DB-7s were the first to see combat; after the fall of France, the bomber served with the Royal Air Force under the British military aircraft designation systems#Names, service name Boston.
