Finnish Minelayer Keihässalmi
Keihässalmi (pennant number "05") was a minelayer of the Finnish Navy. She was commissioned in 1957 and remained in service until 1994, after which she was turned into a museum ship in Turku. The vessel was named after the strait of Keihässalmi, which is located in Sipoo. ''Keihässalmi'' was the first Finnish minelayer to be constructed after World War II. ''Keihässalmi'' was designed according to lessons learned from the ''Ruotsinsalmi'' class minelayers, but with increased size and tonnage. It was stronger, more seaworthy and faster than its predecessor. The construction took place from 1956 to 1957 at the Valmet Oy shipyard in Helsinki. The sinking of the minelayer ''Riilahti'' in 1943 had left a big gap in Finnish mine warfare capabilities, and a new vessel was needed. It would last until the mid-1950s before this was addressed, due to the harsh after-war conditions and war-payments which included many ships to be constructed at Finnish shipyards. The ''Keihässalmi'' w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Museum Ships In Finland
A museum is an institution dedicated to displaying or preserving culturally or scientifically significant objects. Many museums have exhibitions of these objects on public display, and some have private collections that are used by researchers and specialists. Museums host a much wider range of objects than a library, and they usually focus on a specific theme, such as the arts, science, natural history or local history. Public museums that host exhibitions and interactive demonstrations are often tourist attractions, and many draw large numbers of visitors from outside of their host country, with the most visited museums in the world attracting millions of visitors annually. Since the establishment of the earliest known museum in ancient times, museums have been associated with academia and the preservation of rare items. Museums originated as private collections of interesting items, and not until much later did the emphasis on educating the public take root. Etymology Th ...

Minelayers Of The Finnish Navy
A minelayer is any warship, submarine, military aircraft or land vehicle deploying explosive mines. Since World War I the term "minelayer" refers specifically to a naval ship used for deploying naval mines. "Mine planting" was the term for installing controlled mines at predetermined positions in connection with coastal fortifications or harbor approaches that would be detonated by shore control when a ship was fixed as being within the mine's effective range. An army's special-purpose combat engineering vehicles used to lay landmines are sometimes called "minelayers". Etymology Before World War I, mine ships were termed mine planters generally. For example, in an address to the United States Navy ships of Mine Squadron One at Portland, England, Admiral Sims used the term "mine layer" while the introduction speaks of the men assembled from the "mine planters". During and after that war the term "mine planter" became particularly associated with defensive coastal fortificati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ballast Tank
A ballast tank is a Compartment (ship), compartment within a boat, ship or other floating structure that holds water, which is used as ballast to provide hydrostatic stability for a vessel, to reduce or control buoyancy, as in a submarine, to correct Trim (vessel), trim or Angle of list, list, to provide a more even load distribution along the hull to reduce structural Hogging and sagging, hogging or sagging stresses, or to increase Draft (hull), draft, as in a semi-submersible vessel or platform, or a SWATH, to improve seakeeping. Using water in a tank provides easier weight adjustment than the stone or iron ballast used in older vessels, and makes it easy for the crew to reduce a vessel's Draft (hull), draft when it enters shallower water, by temporarily pumping out ballast. Airships use ballast tanks mainly to control buoyancy and correct trim. History The concept of ballast tanks, inspired by nature, can be seen in aquatic life forms like blowfish and the argonaut octopus, ...

Finnish Frigate Matti Kurki
HMS ''Porlock Bay'' was a anti-aircraft frigate of the British Royal Navy, named for Porlock Bay on the northern coast of Somerset. Commissioned in 1946, she served on the American and West Indies Station and as a Fisheries Protection Vessel before being put into reserve in 1949. She was sold to Finland in 1962 and served as the training ship ''Matti Kurki'' until 1974. Service history HMS ''Porlock Bay'' After sea trials ''Porlock Bay'' was commissioned on 14 February 1946 for service in the America and West Indies Station under the command of Lieutenant Dudley L. Davenport. After training she was attached to the Plymouth Local Flotilla and finally sailed for Bermuda with sister ship on 22 July. On arrival a minor collision meant that she did not participate with the Squadron in the Autumn Programme of visits to U.S. ports. Once repaired she took part in visits to Newfoundland and Canada, arriving at St John's on 7 September for the National Convention on the political fut ...

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, when 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 a blockade aided by mines and not an invasion. The function of the fishing fleet's trawlers with their trawl ge ...

Finnish Minelayer Riilahti
Riilahti was a Ruotsinsalmi class minelayer of the Finnish Navy. ''Riilahti'' was commissioned in 1940 and sunk in 1943. The vessel was named after the battle of Riilahti, which was fought between Sweden and Russia in 1714. New minelayers for the navy Funding for two new minelayers had been secured as early as in 1937, but instead the money was used to refurbish the garrison at Mäkiluoto. ''Riilahti'' was launched on December 14, 1940, three weeks after her sister ship ''Ruotsinsalmi''. The ship had an extensively modified propulsion system and hull, compared to her sister vessel, and it took some time before the crew had figured out all the characteristics of the vessel. Originally, the vessels were intended as escort minesweepers for the Finnish navy's coastal defence ships ''Ilmarinen'' and ''Väinämöinen'', and they were therefore designed with a draft of only 1.5 m. ''Riilahti'' was armed with one 75 mm gun, one Bofors 40 mm guns and two Madsen 20 mm anti-a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ruotsinsalmi Class Minelayer
The ''Ruotsinsalmi''-class minelayers were a two-strong class of minelayers in the Finnish Navy. The two ships, comprising and , were constructed in Finland and saw service in the Winter War and World War II. ''Riihahti'' was sunk in an engagement with Soviet motor torpedo boats on 23 August 1943. ''Ruotsinsalmi'' survived the wars and remained in service in the post war Finnish Navy until being withdrawn in the 1970s. Design and description By the late-1930s, the Finnish Navy was focused on defence of the nation and the only ships under construction by Finland were the ''Ruotsinsalmi''-class minelayers and assorted smaller craft. This was due to the majority of the defence budget being awarded to the Finnish Army. The ''Ruotsinsalmi''s measured long overall with a beam of and a draught of . They had a standard displacement of . The vessels were powered by two Rateau diesel engines turning two shafts creating and giving the minelayers a maximum speed of . They had a comple ...
